1 PREFACE

A. The Telecommunications Distribution Design Guide (TDDG) is written to communicate the requirements of Central Washington University (CWU) for the design and installation of telecommunications distribution systems at CWU facilities. • The TDDG is written for an audience of Architects, Engineers and

Designers who are responsible for the design of new or remodeled facilities for CWU where telecommunications infrastructure currently exists or will be installed.

• It is also intended for other low voltage telecommunications Contractors installing telecommunications infrastructure at CWU facilities.

• This document also applies to infrastructure designed and installed by CWU staff, when a formal design is not developed.

B. Telecommunications distribution systems designed for CWU are expected to

support and integrate voice, data, and video telecommunications with common media (fiber optic and unshielded twisted pair (UTP) copper cable).

C. This document was originally adapted (in 1997) from information contained in

the telecommunications standards in use at that time for CWU’s Academic facilities. Under the current revision (2005), it has been again updated to reflect current methods, materials and Standards. The TDDG reflects CWU and Industry Standards in effect as of this publication, including CWU’s Strategic Plan of the Information Technology Services Department (April 2004).

D. It is the responsibility of the telecommunications distribution Designer to

coordinate with the other Designers on a project (architectural, electrical, mechanical, etc.) to determine that other systems are both compatible with and complementary to the telecommunications cabling system. It is critical to coordinate between disciplines during the design phase of a project, rather than making adjustments in the field during construction.

1.1 LOW VOLTAGE SYSTEMS

Wherever practical, telecommunications pathway and cabling systems designed for CWU facilities are expected to support and integrate Building Automation Systems (low voltage systems) that convey information within and between buildings. Telecommunications infrastructure shall be designed in accordance with the requirements in ANSI/TIA/EIA 862 – Building Automation Systems Cabling Standard for Commercial Buildings, and the requirements in this document, to support the Ethernet telecommunications channels on low-voltage devices. Throughout this document, references to “low voltage systems” shall include those referenced in ANSI/TIA/EIA 862, and shall be subject to specific requirements in that standard and as discussed below:

PREFACE LOW VOLTAGE SYSTEMS

5

1.1.1 SHARED OSP PATHWAY

The common outside plant (OSP) telecommunications pathway infrastructure is intended for shared use by the following low-voltage systems, in addition to voice and data systems:

• Building Automation Systems • Fire Alarm Systems • Closed Circuit Television Systems (Analog) • Security Systems • Video Systems (Digital) o Access Control Systems • Energy Management Systems o Alarm Systems • Environmental Control Systems • PLC Control Systems

1.1.2 SHARED OSP MEDIA

The common OSP telecommunications media (cabling) shall be 62.5/125 micron multimode fiber optic cable, singlemode fiber optic cable and 24 AWG unshielded twisted pair (UTP) copper cable (Category 3-rated). The common OSP telecommunications media is intended for shared use by the following low-voltage systems, in addition to voice and data systems:

• Building Automation Systems • Fire Alarm Systems • Video Systems (Digital) • Security Systems • Energy Management Systems o Access Control Systems • Environmental Control Systems o Alarm Systems • PLC Control Systems

1.1.3 SHARED ISP PATHWAY AND MEDIA

The common inside plant telecommunications media shall be 62.5/125 micron multimode fiber optic cable and 24 AWG UTP copper cable (Category 6-rated). The common inside plant (ISP) telecommunications pathway is intended for shared use and the common ISP telecommunications media is intended for separate use by the following low-voltage systems, in addition to voice and data systems:

• Building Automation Systems • Fire Alarm Systems • Video Systems (Digital) • Security Systems • Energy Management Systems o Access Control Systems • Environmental Control Systems o Alarm Systems • PLC Control Systems

Inside plant telecommunications infrastructure intended to support Ethernet telecommunications (or other similar protocols for security and fire alarm systems) shall be designed in accordance with the inside plant telecommunications infrastructure requirements in this document. However, due to the critical nature of these systems, inside plant pathway and cabling serving these systems shall typically homerun to a Mechanical Room or other Low Voltage Electronics Room rather than to a common shared telecommunications rooms. Where low-voltage systems require different media (other than fiber optic cabling and 24 AWG UTP) the systems shall be designed to comply with the pathway and space requirements of this document wherever practical.

1.2 DOCUMENT INTENT

A. CWU has standardized on the ANSI/TIA/EIA1 Commercial Building Telecommunications Standards series and has adopted the BICSI2 Telecommunications Distribution Methods Manual (TDMM), the BICSI Customer-Owned Outside Plant Design Manual (CO-OSP) and the BICSI Telecommunications Cabling Installation Manual (TCIM) as the basis for telecommunications distribution design in CWU facilities. The CWU TDDG is the guide to the application of the ANSI/TIA/EIA Standards, the BICSI TDMM, the BICSI CO-OSP and the BICSI TCIM to the unique circumstances present in CWU facilities and projects. See Figure 1 below for further information.

B. The TDDG is intended to be used in conjunction with the TDMM and CO-OSP

in order to reinforce selected TDMM content as well as highlight any restrictions and/or limitations on TDMM and CO-OSP content in order to meet the specific requirements of CWU facilities. The TDDG is not intended to replace or detract from the TDMM or CO-OSP.

C. The TDDG is not intended to serve as a master specification nor for stand-

alone use on design build projects. This document should serve as a guide for making standards-compliant design decisions that, in due course, will be reflected in a project specification based upon CWU’s Telecommunications Construction Guide Specification (TCGS).

• Designers shall adapt the TCGS “as written” for creating specifications for

a particular project according to the instructions in the TDDG. In other words, Designers shall use the electronic specification section documents (provided by CWU in MSWord format) and then shall make any project-specific edits to the specifications in those documents. Any changes to the specifications shall be done using the “Revision Tracking” features in MSWord.

• Rewriting the TCGS or modifying the format structure or requirements will

not be accepted. D. In addition to the telecommunications specifications for a project, plan

drawings and schematic diagrams shall also be produced by the Designer, in conformance to the guidelines contained in the TDDG.

E. The following diagram depicts the relationships between the ANSI/TIA/EIA

Standards, the BICSI Design Guidelines, the CWU documents (TDDG, TCGS) and the project-specific Construction Documents. Telecommunications distribution infrastructure at CWU facilities shall be designed based on the BICSI design guidelines (the TDMM, the CO-OSP and the TCIM) and compliant

1 Effective December 29, 2000, The Washington State Department of Information Systems has mandated that all Washington State Agencies adopt the ANSI/TIA/EIA Commercial Building Telecommunications Standards as the basis for telecommunications distribution design in State facilities (see Computing and Telecommunications Architecture Standards – Building Wiring, http://www.wa.gov/dis/portfolio/ ). 2The BICSI TDMM is widely considered to be the industry reference text for the design of standards-compliant telecommunications distribution systems (see http://www.bicsi.org/manuals.htm ).

K. Requests to deviate from the CWU requirements may be submitted on a case-by-case basis, in accordance with the instructions in the Project Procedures section of this document. No deviation from the requirements of the National Electrical Code will be allowed. For further information regarding codes and standards, please refer to Chapter 1 in the BICSI TDMM as well as the BICSI CO-OSP Bibliography.

L. The requirements contained in the TDDG are considered to be in addition to

those listed in Instructions for Architects and Engineers Doing Business with Division of Engineering and Architectural Services and the State of Washington Conditions of the Agreement. Where the requirements differ, the issue shall be brought to the attention of the CWU Project Manager - otherwise the more stringent requirement shall apply.

1.3 DOCUMENT STRUCTURE

The TDDG is organized in six sections:

1. Preface 2. CWU Policies 3. Project Procedures 4. Design Criteria 5. Construction Document Content 6. Appendices

A. The Preface (this section) describes this document, its intent and its

relationship to industry standards, practices and the various audiences affected by the document. It also describes how to use this document.

B. The CWU Policies section describes internal CWU telecommunications

policies, requirements, standard practices and processes for designing, installing and operating telecommunications infrastructure.

C. The Project Procedures section describes the required qualifications for

telecommunications Designers as well as the procedures that Designers must follow when working on telecommunications infrastructure projects at CWU facilities. It includes activities that are required throughout the project as well as phase-specific requirements.

D. The Design Criteria section serves two purposes. The first is to describe the

general requirements for CWU telecommunications infrastructure along with the typical features required for different categories of building spaces and construction types. The second purpose is to place limitations on the materials and methods described in the BICSI TDMM and CO-OSP. While the TDMM and CO-OSP describe many materials and methods that are generally accepted in the industry for providing telecommunications infrastructure, CWU facilities have some unique characteristics that impose limitations on some of the materials and methods that otherwise might be acceptable. Some of the practices discussed in the TDMM and CO-OSP are expressly prohibited in CWU facilities. Other practices are permitted in certain areas

PREFACE EXTENTS-OF-CONSTRUCTION

10

(residential halls, for example) but prohibited in other areas such as academic buildings.

Generally speaking, if the BICSI TDMM and CO-OSP do not describe a particular material or method for use with telecommunications distribution infrastructure, it will not be allowed for CWU facilities. In addition, the CWU TDDG places further restrictions on the use of some materials and methods that the BICSI design guidelines support.

E. The Construction Document Content section defines the minimum level of

detail that CWU requires to be present in the telecommunications portion of the Construction Documents for a project. In this section, the required types of details along with the content in the details are both described. This section also briefly describes how to use the TCGS for producing the specification for a particular project. More detailed instructions for producing a project specification based on the TCGS are included with the TCGS.

F. The Appendices section provides standard forms and diagrams along with

example forms and diagrams that are required for CWU telecommunications infrastructure designs.

1.4 EXTENTS-OF-CONSTRUCTION

For the purposes of this document, construction projects are categorized by the extent of the construction work, as follows:

Extent of Construction Definition

• Telecommunications-only Projects involving minor remodeling to create telecommunications spaces and the installation of telecommunications infrastructure

• Light Remodel An existing building undergoing minor or cosmetic remodeling, typically not including significant spatial changes

• Full Remodel An existing building undergoing extensive remodeling, frequently including reallocation of internal spaces

• New Construction A new building or new utility infrastructure Unless otherwise stated, the guidelines defined in the TDDG apply to all four extents of construction. The Designer shall assume that adherence to BICSI guidelines, referenced industry standards, the TDDG and the TCGS are required (unless specifically indicated otherwise) for all facility types and for all extents-of-construction. Where exceptions are permitted, this document will specifically note the facility type and/or extent-of-construction type where CWU’s requirements may differ from generally applicable practices and standards. Adherence to applicable code is always required.

PREFACE CWU PERSONNEL

1.5 CWU PERSONNEL

A. The CWU Telecommunications Policy section of this document applies specifically to CWU personnel. In addition to the CWU Telecommunications Policy section, CWU personnel should be aware of the instructions, requirements and guidelines for Designers contained in the other sections of this document. Also, the TCGS contains additional requirements related to telecommunications distribution system materials and installation methods applicable at CWU facilities.

B. CWU personnel should be familiar with these requirements with respect to

their application on both large-scale telecommunications distribution projects and small-scale “moves/adds/changes” projects. These requirements also apply to in-house operations and maintenance of existing telecommunications distribution systems.

1.6 TELECOMMUNICATIONS DISTRIBUTION DESIGNERS

Telecommunications distribution designers shall be responsible to apply the guidelines, instructions and requirements in this document along with the “hidden-text” guidelines contained in the TCGS, in the course of designing telecommunications distribution infrastructure at CWU facilities.

1.7 CONTRACTORS AND CABLING INSTALLERS

Contractors and cabling installers involved in projects without a formal engineering and design process shall be fluent with and adhere to the requirements of this document and also the requirements for telecommunications distribution system materials and installation methods contained in the TCGS.

2 CWU TELECOMMUNICATIONS POLICIES

The TDDG has been prepared pursuant to Goal #2 / Objective #7 of CWU’s Strategic Plan of the Information Technology Services (ITS) Department (April 2004), regarding the documentation of ITS’ procedures and standards for reference by CWU personnel. This section describes internal CWU telecommunications policies, requirements, standard practices and processes associated with designing, installing, and maintaining and operating telecommunications infrastructure. It is directed toward an audience of CWU staff, including Information Technology Services (ITS) personnel, Facilities Planning & Construction Services (FP&CS) personnel, building maintenance personnel, and any others that may be involved in the design, installation, or maintenance and operation of telecommunications infrastructure at a CWU facility. CWU also operates, occupies, shares or constructs facilities jointly with other academic institutions, such as Washington State University, and Yakima Valley Community College. CWU ITS staff, in conjunction with the CWU Assistant to Provost for University Centers and Community College Relations shall specifically identify when, and to what extent, the TDDG applies to personnel involved in a joint project with another institution. A. CWU personnel designing telecommunications infrastructure for CWU facilities

shall follow the requirements in this document and in the TCGS.

B. Input from CWU ITS must be incorporated in developing the initial and on-going construction schedules. This input is especially important when an early or phased turn-up of buildings is required, but is also vital for the initial start-up of a new facility. Timing on the construction of the main telecommunications room and building, and the backbone cable plant connecting it to key buildings, is a vital consideration for bringing key buildings online at required dates.

C. Management of CWU’s Enterprise Network is the responsibility of the ITS

staff. This includes network design, operations, performance monitoring, optimization, troubleshooting, and disaster recovery. The ITS staff is also responsible for the planning and development of operational and design standards for local area networks (LANs) at all CWU facilities, including the telecommunications infrastructure.

D. CWU’s ITS staff is responsible for installation and support of LAN hardware,

software, data telecommunications and voice systems for both administrative/academic and residential telephones, and certain enterprise network hardware and software.

E. Acquisition of IT services, hardware, software, and related products is the

responsibility of CWU’s ITS staff. IT acquisition rules, licensing agreements, and contracts fall under the authority of the Washington State Department of Information Services (DIS), with very detailed authority delegated to CWU. CWU’s ITS staff who acquire IT goods and services are accountable for ensuring that the procurements meet CWU technology standards and that the

2.1.2 CWU PERSONNEL INSTALLATIONS

A. CWU personnel who install telecommunications infrastructure at CWU facilities must be familiar with the requirements of this document. They must also be familiar with and have a current copy of both ANSI/TIA/EIA-568-B & 569-A.

B. Telecommunications pathway work (both inside plant and outside plant),

when performed by CWU personnel, will require the prior approval of the CWU ITS Infrastructure Specialist. Prior to constructing telecommunications pathway, an RCDD shall be contracted to prepare drawings and specifications for the project. The RCDD shall also be contracted to periodically observe the work while in progress, and upon completion, providing written observation reports following each visit. The RCDD shall also be contracted to produce as-built drawings bearing the RCDD’s logo stamp and signature.

CWU TELECOMMUNICATIONS POLICIES INITIATING NEW PROJECTS – GENERAL

14

C. Use of an RCDD is required for all telecommunications infrastructure work performed by CWU personnel. In the case of horizontal distribution pathway (inside plant conduit), the CWU ITS Infrastructure Specialist may agree to waive this requirement for the design documentation, engineered specifications, and construction observation on a case-by-case basis, or may serve as the RCDD if they hold the designation. The waiver request must be submitted in writing to the CWU ITS Infrastructure Specialist. This waiver cannot be granted for outside plant telecommunications pathway or telecommunications maintenance hole/handhole work.

2.2 INITIATING NEW PROJECTS – GENERAL

The following information is provided as guidance to any CWU department desiring telecommunications or low voltage additions to facilities, or who will be involved in projects requiring such infrastructure.

2.2.1 NEW CONSTRUCTION

2.4 PROCUREMENT AND INSTALLATION POLICY

A. The primary responsibility for the management and use of information systems, telecommunications, and information technology equipment, software, and services rests with each state agency head. Equipment is defined as machines, devices, and transmission facilities used in information processing, such as computers, telephones, and cables. This section highlights certain procurement policies applicable to the telecommunications infrastructure. Readers should consult the Department of Information Services Policy and CWU Policy for the Acquisition and Disposal of Information Technology Equipment for complete details.

B. There are two general methods used for the procurement and installation of

the telecommunications infrastructure. In larger construction projects, the telecommunications infrastructure installation might either be part of the general construction contract or it could be a separate contract.

C. Use of the DIS Master Contract is recommended whenever possible. A

competitive acquisition should be pursued with the Contractors listed on the DIS Master Contract web site3. The procurement of telecommunications infrastructure in large construction projects is a combined effort between the CWU FP&CS Project Manager and the CWU ITS department.

The following policies and procedures apply to the planning and management of telecommunications infrastructure installation as a separate (non-public works) project:

2.4.1 PROCUREMENT POLICY FOR INFORMATION TECHNOLOGY EQUIPMENT

The Department of Information Services (DIS) manages the Washington State policy for the acquisition of information technology equipment. DIS grants CWU a delegated level of acquisition authority based on an IT portfolio style strategic plan

CWU may acquire information technology (IT) resources in one of the following methods: o Conducting a new competitive solicitation o Using an existing CWU contract or DIS Master Contract o Through strategic partnerships o Transferring resources from one agency to another o In limited cases, through a sole source method

B. Typically, the most efficient, cost effective, and preferred method for

procuring telecommunications infrastructure installation services is through the use of the pre-existing DIS Master Contracts for Cabling Equipment, Installation and Maintenance.

C. For additional methods of acquisition, refer to the Department of Information

Services Policy for the Acquisition and Disposal of Information Technology Equipment.

2.4.1.3 Cabling Infrastructure Materials

Standardization on a cabling infrastructure product line permits CWU personnel to be familiar with the installed infrastructure components at all facilities, and helps them to be prepared to handle moves, adds, and changes to the infrastructure in an efficient manner. Standardization also ensures that there will be performance compatibility with the installed base when additions are made to the infrastructure, and that spare parts and components from one facility can be used at other facilities as needed. Finally, product standardization allows CWU to benefit from and manage consistent warranty coverage throughout campus.


19

2.4.1.3.1 Copper Cabling

CWU has standardized on the use of AMP Netconnect® Structured Cabling System (SCS) products and currently uses Category 6 rated products for all new cabling installations. The majority of CWU facilities have an installed base of AMP Netconnect® Structured Cabling System (SCS) products. A. Where additions are made to existing facilities that currently use AMP

Netconnect® SCS products (including new buildings on an existing campus) the addition shall exclusively use AMP Netconnect® products.

B. Where additions are made to existing facilities that currently do not have an

AMP Netconnect® SCS installation, products from the AMP Netconnect® SCS product line shall be used where practical with the eventual goal of standardizing on these SCS products. Written requests for exemption from using AMP Netconnect® products in these cases must be submitted to the CWU ITS Telecom Manager for consideration.

C. The telecommunications infrastructure design for new facilities shall be based

upon the AMP Netconnect® SCS product line. D. Fiber optic related materials from AMP shall not be used on CWU projects.

2.4.1.3.2 Fiber Optic Cabling

The majority of CWU facilities have an installed base of LANscape® fiber optic products from Corning Cable Systems. LANscape® fiber optic products shall be used for both outside plant and inside plant fiber optic infrastructure.

2.4.1.3.3 Other Materials

In addition to the standards listed above, CWU has selected several manufacturers of products for telecommunications cabling systems (racks, cable tray, enclosures, etc.). These manufacturers and their products are identified in the TCGS. The telecommunications distribution designer shall incorporate only these manufacturers into the design, and to design a telecommunications distribution system that can be implemented using products from these manufacturers.

2.4.1.4 Sole Source Procurement

Standardization on the AMP Netconnect® SCS product line and the Corning Cable Systems product line does not imply that there is a sole source for procurement or installation of these products. AMP products and Corning products can be procured through multiple supply sources, and installation can be procured through multiple AMP Netconnect Design and Installation (ND&I) certified cable installation contractors and Corning Cable Systems certified contractors, using competitive solicitations and existing contracts. Refer to Section 2.4.1.2 - Criteria and Methods for Acquisition, above.

CWU TELECOMMUNICATIONS POLICIES LARGE TELECOMMUNICATIONS PROJECTS

2.5 LARGE TELECOMMUNICATIONS PROJECTS

Large telecommunications infrastructure installation projects may be standalone projects to prepare for the installation of new technology, or a separate project concurrently run with a locally managed public works project.

2.5.1 DESIGN PHILOSOPHY

A. An engineered telecommunications design is required for all new construction, major full remodel or light remodeling, including technical specifications and drawings to be used as the basis for competitive bidding for the construction contract.

B. CWU requires the use of Registered Telecommunications Distribution

Designers (RCDD) to design the telecommunications distribution infrastructure for all new construction, major full remodel or light remodeling, and major telecommunications upgrades at CWU facilities. The RCDD designation is recognized worldwide as a design professional that has met specific professional design experience requirements and has successfully completed an extensive examination on the subject of telecommunications distribution design. RCDDs are employed by architectural and engineering firms, and also by telecommunications infrastructure installation Contractors.

C. Telecommunications infrastructure shall be designed and installed in

accordance with applicable codes and industry standards. Due to the unique physical characteristics of many CWU facilities, some technical design solutions are better suited than others. This document identifies which design solutions are appropriate for and approved for common types of buildings and areas at CWU facilities.

D. Telecommunications infrastructure design shall be incorporated during the

preliminary design phase of each project. This will provide CWU ITS the opportunity to influence the design from the start and address telecommunications requirements at appropriate points in the design process. It is imperative that the A/E firm and their RCDD work closely with the CWU ITS Infrastructure Specialist, the CWU ITS Telecom Manager, and the CWU FP&CS Project Manager from the start of each project.

2.6 SMALL TELECOMMUNICATIONS PROJECTS

A. Depending on the size and scope of a small project, the CWU ITS Telecom Manager, working with FP&CS, will determine whether an engineering firm is required to develop a telecommunications distribution design.

B. For small projects or installation of additional cabling, a certified AMP

Netconnect® ND&I contractor can be hired for a limited scope installation. The AMP ND&I contractor must be currently listed as a Contractor on the DIS Cabling Master Contracts.

The only alternative to using a certified AMP Netconnect® ND&I contractor (for copper cabling installation only) is to use AMP-trained CWU personnel under the AMP Netconnect® “Corporate/Institutional program”. (See section

CWU TELECOMMUNICATIONS POLICIES REVIEWING TELECOMMUNICATIONS DESIGNS

3.2 DESIGN REVIEW PROCESS

As noted in Section 3.5 titled “Procedures Related to Project Phases”, the project documents will pass through the design review process at the end of each design phase plus follow-up reviews when necessary. These requirements are in addition to those contained in the State of Washington Conditions of the Agreement and the Instructions for Architects and Engineers.

The following steps correspond to the numbered activities shown on the Design Review Process diagram below: c Each time a review is required, the A/E shall provide copies of the complete project documents set (drawings and specifications for all disciplines involved in the project) for the following people:

• CWU Capital FP&CS Project Manager (PM) (one set) • CWU ITS Infrastructure Specialist (one set) • RCDD Review Consultant5 (two sets)

A B The RCDD Review Consultant will have 3, 5, or 10 days (depending on the project phase) to review the design documents and provide written RCDD Review Comments to the CWU FP&CS PM and the CWU ITS Telecom Manager. def The CWU FP&CS PM and the CWU ITS Infrastructure Specialist will have 5, 8, or 10 days (depending on the project phase) to review the design documents and the RCDD Review Consultant’s comments. The CWU ITS Infrastructure Specialist will create the CWU ITS Review Report, and incorporate the RCDD Review Comments into the report. Following their review, they will distribute the complete set of comments to the RCDD Review Consultant (if present on the project) and hold brief discussions about the comments. If there is no RCDD Review Consultant assigned to the project:

• The CWU ITS Infrastructure Specialist will create the CWU ITS Review Report without RCDD Review Comments

• The CWU ITS Review Report will then be sent to the CWU FP&CS PM for review.

5 On some projects, CWU may hire an RCDD Review Consultant to act in the capacity of an independent reviewer and consultant to CWU. The RCDD Review Consultant will be responsible to review the overall design, paying particular attention to areas of the design that are related to the current or future operation and maintenance of the telecommunications system, and sometimes low voltage systems other than voice and data. The RCDD Review Consultant will identify issues that do not appear to be compliant with the requirements in the TDDG and the requirements contained in the TCGS.


28

gh The CWU FP&CS PM will submit the RCDD Review Report to the Designer. The Designer will then be given five days to review the comments and respond to them in writing. Negative responses to any comment shall include a discussion of the reasons for non-compliance. ij Finally, a meeting or teleconference will be held with the CWU FP&CS PM, the CWU ITS Infrastructure Specialist, the RCDD Review Consultant and the Designer to discuss the review comments and the Designer’s responses. Following the meeting, the Designer shall revise the design in accordance with the CWU’s resolution for each comment.

A. The Designer shall require CWU to review the documents and respond

with written review comments to the Designer at each phase of the design. The Designer shall not proceed with the next phase of telecommunications design without receipt of written comments from the CWU ITS Infrastructure Specialist.

B. The Prime Consultant shall be responsible to determine that the review

process is conducted in accordance with CWU’s requirements, and shall participate in the review process to determine that the review comments are satisfactorily addressed.

3.2.1 RCDD REVIEW CONSULTANT

For projects where CWU hires an RCDD Review Consultant, the prime consultant (Designer or A/E) shall provide two sets of the drawings and specifications (from all disciplines involved in the project) for the RCDD Review Consultant. The RCDD Review Consultant will not perform any design services. The RCDD Review Consultant could be asked to do the following:

3.2.1.1 Typical Document Review Scope

1. Review telecommunications distribution system design:

o For compliance with CWU and Industry standards o To identify apparent conflicts (routing, electromagnetic interference, etc.)

with other discipline’s designs o For indications of coordination with telephone service providers or other

utilities o For general document clarity

2. Review the completed needs analysis report. 3. Review the cutover plans. The RCDD Review Consultant shall review the documents according to CWU’s requested review scope and then produce a report consistent with the format shown in Appendix 6.1 that addresses at a minimum the following items:

3.2.1.2 Other Services (upon specific CWU request)

A. On some projects, CWU may also use an RCDD Review Consultant to provide services during the construction phase. These services may include submittal review and “big-picture” construction observation services. In these situations however, the Designer always remains responsible for submittal review, construction observation, punchlist management, and other standard services as indicated in the Instructions for Architects and Engineers Doing Business with Division of Engineering and Architectural Services (published by the Washington State Department of General Administration).

B. In these situations, the RCDD Review Consultant shall provide written

comments to CWU and to the Designer. In turn, CWU will decide how to act on the written comments, and then direct the A/E, Designer or Contractor accordingly. The RCDD Review Consultant shall not, under any circumstances, give direction to the A/E, Designer or Contractor.

PROJECT PROCEDURES ARCHITECT/ENGINEER TEAMS

33

3.3 ARCHITECT/ENGINEER TEAMS

It is imperative that the telecommunications design be incorporated during the preliminary architectural design phase. To accomplish this, the architects and engineers on the design team shall work closely with the designated project RCDD, the CWU ITS Telecom Manager, and the CWU FP&CS Project Manager beginning with the Schematic Design phase of the project.

3.3.1 CROSS DISCIPLINE COORDINATION

Successful telecommunications projects require frequent, thorough design coordination between the disciplines involved in the project. The Designer shall be primarily responsible to coordinate the telecommunications requirements and design features with the designs produced by the other Designers on the project. At a minimum, the following aspects of the design shall be coordinated:

3.3.1.1 Outside Plant Telecommunications Infrastructure:

• Ductbank routing around obstacles (trees, tunnels, buildings, existing ductbanks, etc.)

• Coordinate the locations of maintenance holes and hand holes to determine that they are not located in areas of water concentration. Site requirements, drainage, traffic, joint usage, utility requirements, etc.

• Proximity of ductbanks to sources of EMI, including power distribution feeders • Proximity of ductbanks to steam piping • Routing of entrance conduits through buildings • Backbone cabling requirements of other disciplines (fire alarm, HVAC,

security, CATV, etc.)

3.3.1.2 Horizontal and Intra-building Backbone Telecommunications Infrastructure:

• HVAC cooling requirements for telecommunications rooms (TR) • HVAC ductwork routing (avoiding TR ceiling spaces) • Plumbing routing avoiding TR spaces • Lighting requirements for TRs • Power requirements for TRs • Power requirements for work areas (receptacle locations near

telecommunications outlet locations) • Proximity of cabling to sources of EMI • Routing of telecommunications conduits through and location of

telecommunications pullboxes in congested areas (HVAC ductwork, plumbing, electrical, etc.)

• Floor treatments in TRs More information regarding the above requirements is available in the Design Criteria section in this document.

PROJECT PROCEDURES GENERAL PROCEDURES

34

3.4 GENERAL PROCEDURES

3.4.1 PROCUREMENT AND INSTALLATION

A. CWU uses several methods for the procurement and installation of the telecommunications infrastructure: • DIS Master Contract • Competitive Bid • Existing CWU Contract • Strategic Partnerships • Inter-agency Resource Transfer • Sole Source (limited use)

B. In larger construction projects, the telecommunications infrastructure

installation might be part of the general construction contract or it could be a separate contract. CWU uses the Washington State DIS Master Contract6 whenever appropriate for a given project. When the DIS Master Contract is not being used, a competitive bid shall be sought, using the Contractors listed on the DIS Master Contract website that are approved by CWU. Generally, the procurement and construction of telecommunications infrastructure will be a combined effort between the CWU FP&CS Project Manager and the CWU ITS Telecom Manager.

3.4.2 CAD FILES

The Designer shall coordinate with the A/E to determine that the electronic CAD files used for backgrounds for the telecommunications design are consistent with the CAD file backgrounds used by the other disciplines on the project.

3.4.3 ALTERNATIVE DESIGN REQUEST (ADR)

A. It is not the intent of CWU to rigidly impose standards on every aspect of a telecommunications system design. Each design is unique and special requirements may lead to situations in which deviations from the standards are warranted.

B. This document identifies specific design solutions that are intended to meet

the technical requirements of CWU telecommunications and information technology systems at most CWU facilities. Design issues that are not consistent with the requirements in this document shall require prior approval through the CWU Alternative Design Requests (ADR) process. Requests to deviate from industry standards or CWU design solutions will be considered on a case-by-case basis. Any request to deviate from applicable code requirements or to deviate from manufacturer’s warranty requirements will not be approved.

C. If the Designer feels that deviation from a given standard is warranted, the

Designer shall submit a written deviation request to CWU. The Designer may, upon written approval from CWU, incorporate the design deviation into the overall design. CWU approval is required on a project-by-project basis - the

6 As of this writing, more information about the Washington State DIS Master Contract is available at http://techmall.dis.wa.gov/master_contracts/MC.asp


35

Designer shall not assume that a deviation approval for one project means that the deviation will necessarily be approved for a subsequent project.

The request shall include a complete description of the proposed alternative design identifying: 1. The type of facility; 2. The conditions at the facility; 3. The approved design solution as described in this document or as

described in the standards referenced in this document; 4. The proposed alternative design; 5. A list of the guidelines and standards referenced in this document with

which the alternative design will not be in compliance, and the effect of non-compliance, both short and long term;

6. The reason for wishing to use the alternative design; 7. The Contractor or personnel performing the construction;

Finally, the Designer shall provide written comments indicating that the proposed alternative design will meet the applicable CWU system performance requirements, and identifying any performance limitations, drawbacks and benefits from using the alternative design.

D. The Designer shall be responsible to determine that the ADR process is

properly conducted. For projects where the Designer is not the prime consultant, the prime consultant shall also be responsible to determine that the ADR process is properly conducted, and shall participate in the process (review, acknowledge and address issues) to determine that CWU’s requirements are met.

PROJECT PROCEDURES PROCEDURES RELATED TO PROJECT PHASES

SCHEMATIC DESIGN AND FIELDWORK

37

3.5 PROCEDURES RELATED TO PROJECT PHASES

Telecommunications projects are typically conducted in phases. In addition to the requirements contained in the State of Washington Conditions of the Agreement and the Instructions for Architects and Engineers, Designers of telecommunications distribution systems for CWU facilities have the following phase-related responsibilities:

3.5.1 SCHEMATIC DESIGN AND FIELDWORK

A. Telecommunications projects on existing CWU campuses will require preliminary fieldwork to document the existing cabling and infrastructure systems into which the new cabling and infrastructure will integrate. CWU believes that this information is vital to a successful project.

B. The Designer shall visit the project site during the Schematic Design phase to

perform the preliminary outside plant fieldwork. The Designer shall create the following types of documentation based on information gathered while onsite: • Take digital photographs of existing telecommunications pathways, spaces

and cabling that affect or are affected by the new project work. • Verify existing or create new butterfly diagrams of each existing

maintenance hole and handhole that is associated with the project, identifying each cable and conduit in each maintenance hole and handhole. A sample butterfly diagram is shown in Appendix 6.2.

• Verify existing or create a new backbone schematic diagram showing the existing outside plant cabling in the area associated with the new project and the existing cross connection strategy. A sample backbone schematic diagram is shown in the Appendix 6.3.

C. The Designer shall visit the project site during the Schematic Design phase to

perform preliminary field investigation of the horizontal and intra-building backbone telecommunications infrastructure. The Designer shall create the following types of documentation based on information gathered while onsite: • Take digital photographs of existing telecommunications rooms and work

areas that affect or are affected by the new project work. • Verify existing or create a new riser diagram showing the existing intra-

building backbone cabling associated with the new project and the existing cross connection strategy.

• Investigate and document the routing of existing horizontal pathways and cabling that are affected by the project.

• Verify existing or create new elevation diagrams of each telecommunications rack and each wall within each TR affected by or affecting the new project work.

D. The Designer shall also conduct a needs analysis (involving CWU personnel) to

identify and describe the required features and functionality of the new telecommunications infrastructure.


DESIGN DEVELOPMENT

38

E. The information gathered during the fieldwork, combined with the results of the needs analysis shall be the starting point for Schematic Design of the proposed new work.

F. Schematic Design documents shall show the following information:

• Building and local distribution • Telecommunications Room sizes and locations • Major distribution pathways • Backboard locations

G. Upon completion of the Schematic Design documents, the standard Design

Review Process shall be conducted prior to progressing to the Design Development phase.

3.5.2 DESIGN DEVELOPMENT

A. The Designer shall modify the design documents to address the review comments received during the Schematic Design Phase.

B. During the Design Development phase, the Designer shall obtain the

assistance of manufacturer product representatives to review the project specification (adapted by the Designer from the CWU Telecommunications Construction Guide Specification) to determine that the correct part numbers have been included for each product in the specification.

C. If the design will make use of existing outside plant pathway, the ducts must

be proven during the Design Development phase in order to ensure that the selected pathway is clear and serviceable. Proving the ducts prior to construction will not only aid the Designer in selecting the appropriate pathway for use, it will also minimize unexpected (and costly) problems encountered during construction. Acceptable proving methods are, in order of preference:

• Pushing/pulling a test mandrel through the duct • Blowing/pushing/pulling a ball through the duct • Pulling on a previously installed pull cord and observing free movement on

both ends

The proving method should be selected only after determining the quantity and size of the telecommunications media to be placed in the duct and after reviewing the condition of the duct in the field.

D. In addition to the content shown on the Schematic Design documents, the

Design Development documents shall show the following information: • Schematic diagrams • Outlet locations and port counts for each outlet

E. Upon completion of the Design Development documents, the standard Design

Review Process shall be conducted prior to progressing to the Construction Document phase.


CONSTRUCTION DOCUMENTS

39

3.5.3 CONSTRUCTION DOCUMENTS

A. The Designer shall modify the design documents to reflect the accepted review comments received during the Design Development Phase.

B. In addition to the content shown on the Schematic Design and Design Development documents, the Construction Documents shall show the following information: • Raceway routing plans • Telecommunications room wall elevation details • Rack elevation details • Maintenance Hole/Handhole details. Ducts are to be assigned during the

course of design, not during construction. Duct assignments must be approved by CWU prior to the release of construction documents.

• Ductbank details The Construction Documents are also expected to contain the items discussed in the Construction Document Content section of this document.

C. It is expected that the Designer will expend considerable effort coordinating details between different disciplines during the design process. Non-coordinated pathway/raceway is not acceptable to CWU.

D. Upon completion of the Construction Documents, the standard Design Review

Process shall be conducted. The Designer shall then modify the documents to reflect the accepted review comments associated with the Construction Documents prior to the Bidding Phase.

E. Upon completion of the Final Construction Documents, the standard Design

Review Process shall be again conducted as described above. The Designer shall modify the documents to address the review comments associated with the Final Bid Documents prior to the bidding phase rather than “by addendum.”

3.5.4 BIDDING

On projects where a pre-bid walkthrough is held, the Designer shall attend the walkthrough and shall provide the bidders with a written list of materials and practice requirements that the bidders might find peculiar and that might affect the bids if such requirements are overlooked. Noteworthy items would typically be requirements that are more restrictive than practices considered acceptable for other commercial projects. The Designer shall consider the following items for inclusion on such a list, as well as any other items applicable to the project: • The use of flex-conduit is prohibited. • The installation of conduit under-slab or in-slab is prohibited. • The requirement for no more than two 90 degree bends in any conduit run. • The fact that telecommunications standards are more stringent than electrical

installation requirements.


CONSTRUCTION OBSERVATION

40

3.5.5 CONSTRUCTION OBSERVATION

A. The Designer shall review the Contractor’s submittals that are required by the Construction Documents. When the Contractor’s submittals include materials or methods that deviate from CWU standards, the Designer shall either: • Reject the specific materials and methods that do not comply, when the

Designer believes that they constitute undesirable solutions. • Pursue the ADR process to seek separate approval for each specific

material and method that the Designer believes would constitute a better solution.

B. The Designer (RCDD) shall visit the construction site frequently to observe

the construction quality and status. The Designer shall confer with the CWU FP&CS Project Manager prior to proposing services for the project to determine an appropriate site-visit frequency for the project. On average, one site visit per week will typically be required for building-wide projects and one and a half site visits per week will be typically required for campus-wide projects. The site visit frequency will likely change during the construction as the telecommunications-related activity increases and decreases.

C. During the site visits, the Designer shall take digital photographs of existing

and new telecommunications pathways, spaces and cabling, both intra-building and outside plant and that are related to the project. In particular, the Designer shall photograph infrastructure that will later be concealed during the course of construction.

D. It is the responsibility of the Designer to verify that the Contractor properly

labels all outside plant cabling during construction. Inadequate or incomplete labeling is not acceptable.

E. Accurate record drawings are considered critical for the efficient operation of

CWU facilities. During these site visits, the Designer shall observe and report on the Contractor’s progress toward staying current with the record drawings notations.

F. After each site visit, the Designer shall submit a written report describing the

observed construction progress. Observations shall be documented in the report with annotated digital photographs and a written description of any problems, a description of the requirements in the Construction Documents and the resolution to the issues. For each item requiring corrective attention, the report shall describe the following:

• A description of the issue • Applicable requirements in the Construction Documents • Applicable CWU standards, industry standards and codes • Corrective options available to CWU • Designer’s recommendation

G. The Designer shall submit the construction observation reports via email to

the CWU FP&CS PM and the CWU ITS Infrastructure Specialist as soon as possible following each site visit. The reports shall also be reviewed at the


POST-CONSTRUCTION

41

next construction meeting. A timely report submission will aid the Designer and CWU in identifying potential problems early in the construction process.

H. The Designer shall review the cable test reports produced by the Contractor

for each cable installed during the project. The Designer shall verify that the following conditions are addressed in the cable test reports:

• The cable test report shall be automatically produced by the test

equipment • The report shall indicate that the cable passed the test • For Fiber Optic Cabling: the cable test report shall indicate a headroom dB

value that is equal to or better than the value calculated in the link-loss budget

• For Fiber Optic Cabling: the cable test report shall indicate the correct Nominal Velocity of Propagation (NVP) indicated on the cut sheet from the cable manufacturer

3.5.6 POST-CONSTRUCTION

A. The Designer shall review the Operation and Maintenance information provided by the Contractor for the telecommunications distribution system. The Designer shall verify that information is included for each component in the telecommunications distribution system. Upon approval of the content in the Operation and Maintenance information, the Designer shall submit the information to local CWU ITS Staff with written documentation indicating that the Designer has reviewed the information and that it appears to meet the requirements in the Construction Documents.

B. The Designer shall provide record drawings and record documentation to CWU

(based on documents that have been “red-lined” by the Contractor). Record documents shall be provided in electronic CAD format where applicable, in addition to requirements put forth by the Designer’s contract with CWU.

C. The Designer shall verify that the cabling contractor provides the appropriate

manufacturer warranty certification documentation to CWU.

DESIGN CRITERIA PROCEDURES RELATED TO PROJECT PHASES

POST-CONSTRUCTION

42

4 DESIGN CRITERIA

A. The CWU TDDG is not intended to be a comprehensive design guide resource for telecommunications design at CWU facilities. The Designer shall look primarily to the BICSI TDMM and CO-OSP for design guidance. The Construction Documents produced for each project shall be consistent with the installation practices described in the BICSI Telecommunications Cabling Installation Manual (TCIM).

B. Where ANSI/TIA/EIA standards or BICSI manuals offer multiple choices with a

preferred method identified, and where the CWU TDDG does not select one method over another or define specific requirements precluding use of the preferred method, the ANSI/TIA/EIA or BICSI-preferred method shall be selected.

C. Where ANSI/TIA/EIA Standards or BICSI manuals identify warnings regarding

potential adverse effects from certain design or installation methods, the design or installation method used should typically be the method with the least potential for adverse effects.

D. Telecommunications distribution systems shall be designed for construction

using materials from the current product lines of the manufactures upon which CWU has standardized. For copper cabling and related materials, CWU has standardized on the AMP Netconnect® Structured Cabling System (SCS) product line. For fiber optic cabling and related materials, CWU has standardized on the Corning Cable Systems LANscape® product line. In addition to the standards listed above, CWU has selected several manufacturers of products for telecommunications cabling systems (cable, connectors, termination blocks, patch panels, etc.) and telecommunications distribution hardware (racks, cable tray, enclosures, etc.). These manufacturers and their products are identified in the TCGS. The Designer is required to incorporate only these manufacturers into the design (unless otherwise directed by CWU) and to design a telecommunications distribution system that will be suitable for the use of products from these manufacturers. The construction documents shall require that the installation workmanship fully comply with the current installation requirements from the manufacturers of these products.

E. Any request to deviate from the requirements of the National Electrical Code or the AMP Netconnect SCS warranty will not be accepted. The Designer shall seek approval for designs that are not consistent with CWU TDDG requirements through the CWU Alternative Design Request (ADR) process. Requests to deviate from industry standards or CWU design solutions will be considered on a case-by-case basis by the CWU ITS Infrastructure Specialist. Designers shall contact the CWU ITS Infrastructure Specialist to discuss proposed alternatives before spending significant time researching or

DESIGN CRITERIA CODES, STANDARDS AND REGULATIONS

preparing an ADR.

F. Telecommunications distribution infrastructure shall fully comply with the current CWU TDDG, the current Washington State Department of Information Services (DIS) “Computing and Telecommunications Architecture Standards – Building Wiring”, the current ANSI/TIA/EIA Commercial Building Telecommunications Standards and the National Electrical Code (NEC).

G. The following subsections are arranged to mirror the chapter sequence of the

BICSI TDMM 10th Edition (the subsection numbers below are in the form of 4.x where x represents the chapter number in the BICSI TDMM). • Each TDDG subsection contains commentary and requirements regarding

the application of the BICSI TDMM to CWU Projects. In particular, each section contains limitations and prohibitions on specific materials and methods discussed in the BICSI TDMM.

• Where no TDDG subsection is written (addressing comments about or requirements for the corresponding TDMM subchapter) the Designer can assume that the TDMM subchapter applies as written.

H. Please refer to the Bibliography and Resources section and Glossary section of

the BICSI TDMM for definitions, abbreviations, acronyms and symbols used for describing and documenting telecommunications infrastructure at CWU facilities.

Other terms are defined in the Glossary located in Appendix 6.8 of this document.

4.1 CODES, STANDARDS AND REGULATIONS

Please refer to the Codes, Standards and Regulations section of the BICSI TDMM for information regarding the codes, standards and regulations required for telecommunications infrastructure at CWU facilities.

4.2 PRINCIPLES OF TRANSMISSION

Please refer to the Principles of Transmission section of the BICSI TDMM for general information regarding the design of telecommunications distribution infrastructure.

4.3 ELECTROMAGNETIC COMPATIBILITY

Please refer to the Electromagnetic Compatibility section of the BICSI TDMM for general information regarding the electromagnetic interference with and clearance requirements for telecommunications infrastructure. The following requirements take precedence over the BICSI TDMM guidelines for telecommunications infrastructure at CWU facilities: Telecommunications infrastructure shall maintain minimum separation distances from sources of electromagnetic interference (EMI) as listed below. Where the NEC or local codes require greater separation distances than those listed below, the largest separation distance shall be maintained.

DESIGN CRITERIA WORK AREAS

TELECOMMUNICATIONS & EQUIPMENT ROOMS

44

Separation distances apply equally to both copper cabling and fiber optic cabling. Even though fiber optic cabling is impervious to EMI, once a pathway is established for fiber it could later be used for copper cabling.

4.3.1 TELECOMMUNICATIONS & EQUIPMENT ROOMS

TRs shall not be located in or adjacent to areas containing sources of electromagnetic interference or radio frequency interference (RFI) such as photocopy equipment, large electric motors, power transformers, arc-welding equipment, radio transmitting antennas, etc. This is a critical consideration, as EMI and RFI can render data networks inoperable. No point within the TR or ER shall be closer than 3 m (10 ft) to transformers, power panels or equipment rated at greater than 480 V.

4.3.2 INSIDE PLANT PROXIMITY TO SOURCES OF EMI

Based on previously published telecommunications design guidelines, ISP telecommunications pathways shall be designed to have the following clearances: o 4 feet from motors or transformers o 1 foot from conduit and cables used for electrical power distribution o 5 inches from fluorescent lighting

4.3.3 OUTSIDE PLANT PROXIMITY TO SOURCES OF EMI

OSP telecommunications infrastructure designs shall adhere to the governing clearance requirements of the NEC and NESC.

4.4 WORK AREAS

Please refer to the Work Areas section of the BICSI TDMM for general information regarding the design of work area telecommunications infrastructure. The following requirements take precedence over the BICSI TDMM guidelines for telecommunications infrastructure at CWU facilities: A. Goal #6 of CWU’s Strategic Plan of the Information Technology Services (ITS)

Department (April 2004) describes CWU’s intent as follows:

“Implement and support a reliable and capable technology infrastructure in support of voice, video and data while allowing for near anywhere/anytime system access via available technology and services.”

The Designer shall identify work areas pursuant to the above goal, and shall work cooperatively with CWU ITS staff to design telecommunications infrastructure to appropriately meet the goal.

B. CWU considers undercarpet telecommunications cabling (UTC) solutions to be

undesirable in most cases. The Designer shall discuss any apparent justifications for undercarpet cabling with the CWU ITS Infrastructure Specialist prior to its inclusion in a design.


DEVICE BOX CONSIDERATIONS

45

C. There shall be at least one general-purpose convenience power outlet (120VAC, 15 Ampere minimum) located within three feet of every telecommunications outlet. The Designer shall discuss any application-specific needs with CWU IT staff and adjust the power outlet locations and amperage accordingly.

• In the case of new construction and full remodel projects, the power

outlet associated with each telecommunications outlet shall be a 4”x4” device box (dual gang) with four power receptacles. It is the Designer’s responsibility to coordinate with the electrical engineer to ensure that power outlets are located near telecommunications devices boxes.

• In the case of light remodel and telecommunications-only projects, it may

be difficult to meet this requirement. Therefore, where existing power outlets are not located within six feet of each telecommunications outlet, the Designer shall alert CWU IT staff and request their consideration of the situation on a case-by-case basis.

4.4.1 DEVICE BOX CONSIDERATIONS

A. Device boxes shall not be “combo” boxes (i.e. boxes used for both telecommunications and power, CATV, etc.)

B. Device boxes shall not be mounted in the floor (i.e. “floor boxes”) except

where no suitable alternative exists. If device boxes must be mounted in the floor, each device box shall be served with its own individual conduit - floor boxes shall not be “daisy-chained” together.

C. Power outlets may be combined with CATV and telecommunications cabling in

floor boxes if the power wiring is routed to the floor boxes separately from the other cable media and if the floor box provides for metallic barrier segregation of the power and telecommunications cabling within the box.

D. Providing spare ports for an outlet in a work area and providing spare outlets

in a room are encouraged within the limitations of the project budget to meet projected future needs.

E. CWU may wish to terminate both telecommunications cabling and CATV

coaxial cabling in a shared device box. CWU permission for this method is required on a project-by-project basis.

F. Device boxes for telecommunications outlets shall be mounted at the same

height as the electrical power receptacles.

4.4.1.1 For New and Full Remodel Construction

A. A device box shall be provided for each telecommunications outlet. Device boxes shall be 4”x4”x3-½” (where 3-½” is the depth of the box and extension ring). Device boxes shall be recess-mounted.

B. Surface mounted device boxes are not acceptable. However, for CMU walls or


DEVICE BOX CONSIDERATIONS

46

other wall types that may obstruct cable or conduit installation, the Designer shall request direction from the CWU ITS Infrastructure Specialist on a case-by-case basis.

C. In general, two device boxes shall be provided for each work area and shall be located (subject to design constraints) on opposing walls. Each device box shall have two ports, unless the telecommunications outlet is intended to serve a wall-mounted phone or other dedicated application requiring a single port.

D. For classrooms in academic buildings, a minimum of one device box shall be

located on each classroom wall. E. For Residence Halls, each dorm room shall be provided with no less than two

ports per resident, located within each resident’s study space. Some study spaces may serve two students within a single space, in which case it might be possible to install a single device box located where it would be reachable from both workspaces within the space. For dorm rooms having a common/living area, an additional device box with two ports shall be installed in the common/living area. These situations shall be investigated by the Designer and reviewed with CWU.

4.4.1.2 For Light Remodel and Telecommunications-only Projects

A. Existing device boxes and conduits shall be reused where existing boxes are standards-compliant or where it can be verified that the existing conduits and boxes will permit telecommunications cabling to be installed without negatively affecting the performance of the cabling. The bend radius of the cabling inside each box will be considered carefully in evaluating existing boxes. For concealed conduits that can not be verified, the CWU ITS Infrastructure Specialist will decide whether they should be reused on a case-by-case basis.

B. A device box shall be provided for each telecommunications outlet. Device

boxes shall be recess-mounted wherever possible and shall be 4”x4” and at least 2 ½” deep (a 3 ½” depth is preferable). Surface mounted device boxes (if required) may be standard single gang (2” x 4”) and at least 2 ½” deep.

C. In general, a minimum of or two device box shall be provided for each work

area, preferably on opposite walls. A minimum of one device box shall be located in each classroom.

D. For Residence Halls, a minimum of one device box shall be located in each

dorm room, with no less than one port per resident.

• It may be permissible to use faceplate mounting brackets in lieu of device boxes. CWU permission for this method is required on a project-by-project basis.

DESIGN CRITERIA HORIZONTAL DISTRIBUTION SYSTEMS

HORIZONTAL PATHWAY SYSTEMS

47

4.5 HORIZONTAL DISTRIBUTION SYSTEMS

Please refer to the Horizontal Distribution Systems section of the BICSI TDMM for general information regarding the design of horizontal distribution pathway and cabling. The following requirements take precedence over the BICSI TDMM guidelines for telecommunications infrastructure at CWU facilities:

4.5.1 HORIZONTAL PATHWAY SYSTEMS

CWU has standardized on the use of cable tray as the primary feeder pathway and the use of conduit to route cabling from cable trays to outlets in its buildings. CWU sometimes uses J-hooks for routing cabling. The process of selecting the type of pathway for a particular project shall be a cooperative effort involving the Designer and the CWU ITS Infrastructure Specialist.

4.5.1.1 General Pathway Design Considerations

A. During the Schematic Design phase, the Designer shall discuss pathway type and size with the CWU ITS Infrastructure Specialist.

1. The Designer shall discuss the relative merits of the pathway options

available and shall assist the CWU ITS staff and the project design team to select the most appropriate pathway solution for the project.

2. The future growth anticipated for the facilities affected by the project shall be discussed. Horizontal feeder pathways (cable trays, conduits from TRs to distribution junction boxes) shall be sized to support the initial cabling installation plus a minimum of 25% growth.

B. Spare pathway shall be designed to terminate at building perimeters where

future expansion is anticipated. C. When considering the design of a ceiling-located cable tray or J-hook

pathway, the Designer shall verify that the pathway locations will comply with accessibility and clearance requirements. Cable tray and J-hook pathways routed through ceiling spaces shall be designed such that all installed cable is conveniently accessible after construction for both cable maintenance and to install subsequent cable additions. Conduit shall be used to span inaccessible areas where the pathway will cross “hard-lid” ceilings or where ceiling tiles are not readily removable or where accessibility is impeded.

D. Pathway routing shall remain on the same floor as the telecommunications

room and telecommunications outlets served by the pathways. Where project-specific conditions exist that justify other routing, the Designer shall request CWU approval through the ADR process.

E. “Poke-thru” penetrations to the ceiling space of the floor below are normally

not permitted. Permission to use poke-thru pathways in any circumstance requires an ADR on a project-by-project basis.

1. For light remodel construction, poke-thru penetrations may be allowed

given budgetary, project size, or other limiting factors.



48

2. If no other option is available, poke-thru’s may be used if there is a

suitable telecommunications room on the same floor as the telecommunications outlet. In this case, an additional sleeve, slot, or conduit raceway must be installed which to serve as pathway back to the originating floor. The length of pathway through the ceiling space of the floor below shall be minimized. Even if there is not a telecommunications room on the originating floor, it is desirable to bring the pathway back to the originating floor so that it may join with other pathway on the originating floor, and thus route together to the telecommunications room.

3. For Residence Halls, using poke-thru pathway floor-to-floor and

distributing horizontally either in the bottom floor or in the attic may be permitted.

F. For computer lab applications, CWU has standardized on the use of 3” high

access flooring to distribute telecommunications cabling to each computer workstation.

4.5.1.2 Pathways for New Construction and Full Remodel Projects

A. J-hook pathway systems are not permitted. B. Surface raceways and surface mounted device boxes are not permitted.

4.5.1.3 Pathways for Light Remodel and Telecommunications-only Projects

A. For light remodel construction, there may not be an existing (or suitable space for a new) telecommunications room available on the same floor as an outlet. While pathways shall generally be designed from the device box serving the telecommunications outlet to the nearest telecommunications room on the same floor as the outlet, his requirement may be waived.

B. Existing pathways shall be reused where existing raceway is standards-

compliant or where it can be verified that the existing pathway will permit telecommunications cabling to be installed without negatively affecting the performance of the cabling. Where a pathway is concealed or cannot otherwise be verified, the Designer shall request direction from the CWU ITS Infrastructure Specialist on a case-by-case basis.

C. Where existing pathways cannot be reused, or where additional pathways are

required:

1. J-hook pathway may used. J-hook pathways shall be established through concealed spaces. J-hook pathways shall be sized for a minimum of 100% expansion. D-ring pathways are not permitted.

2. When 40 or more cables are designed to be routed through an area, the

use of cable tray or conduit shall be considered in lieu of J-hooks. D. It may be permissible to use faceplate mounting brackets in lieu of device



49

boxes. In these cases, cabling is routed to the outlet location through interstitial wall spaces. CWU permission for this method is required on a project-by-project basis.

E. For Residence Halls, it may be permissible to route pathway (such as soffits)

or raceway directly from room to room. Where soffit is used, the soffit lids shall be secured with tamper resistant screws (such as Torx head) in order to discourage vandalism. CWU permission for this method is required on a project-by-project basis.

4.5.1.4 Cable Tray Pathway Systems

A. In general, cable tray systems shall be located in corridor or office throughway spaces, and shall not be installed above office or classroom space. Distances from EMI/RFI sources shall be maintained according to the Electromagnetic Compatibility section (above), regardless of whether the raceway is routing copper or fiber optic based media.

B. Projects designed using cable tray shall use welded-wire type trays. Where it

is not possible, to conceal cable trays, the design shall specify aesthetically finished aluminum or steel cable trays.

C. Cable trays shall not be shared with power cables. D. Conduit used to route cabling from the cable tray to the work area outlet shall

be sized a minimum of 1”.

4.5.1.5 Conduit and Junction Box Pathway Systems

A. In “slab-on-grade” constructed buildings, conduits both in and under the ground floor slab are considered “wet locations” where indoor-rated cabling is not permitted. Therefore, conduit serving the main floors of such buildings shall be routed in walls and ceilings - not in or under the slab. Intra-building and horizontal pathways shall only be installed in “dry” locations where indoor cabling can be protected from humidity levels and condensation that are beyond the intended range of indoor-only rated cable.

B. Where conduit runs terminate at cable trays, the conduits shall be arranged in

an organized, uniform manner to facilitate an orderly cable transition from conduit to cable tray.

C. Where conduit runs terminate in telecommunications rooms, the conduits

shall be arranged in an organized, uniform manner to facilitate an orderly cable transition from conduit to backboard.

D. Non-metallic conduit and flex conduit shall not be used for horizontal

pathways. E. Conduits shall not be filled beyond 40%. The Designer shall verify the outer

diameter of the cabling for a project at the time of the design to determine the maximum number of cables that can be placed inside a conduit without



50

exceeding the 40% fill limitation.

The following table shows the quantity of cables that can be placed in a single EMT conduit, based on the typical current outside diameter dimensions for both CMR and CMP rated CAT3, CAT5E and CAT6 cables from AMP:

AMP Netconnect Cables, OD (in.)

F. In new construction, all work area outlets shall have a minimum 1” conduit

routing from the device box to an accessible cable pulling location. The conduit size shall be increased as necessary for the quantity of cables to be installed. Where new conduit is installed in existing buildings, the Designer shall notify CWU when existing conditions prevent the use of one-inch trade size conduit as a minimum conduit size.

G. Device boxes shall not be “daisy-chained.” Each device box shall be complete

with its own dedicated conduit to the nearest distribution point/pathway. H. Junction boxes and pull boxes shall be oriented for access doors to open from

the area where the cable installer will normally work. This is typically from the bottom (floor) side of the box.

I. Ceiling access to junction boxes and pull boxes shall be designed to allow full

access to the door and adequate working room for both the installation personnel and proper looping of the cable during installation.

J. Junction boxes and pull boxes shall be located in spaces that are easily

accessible during normal working hours – such as hallways and common areas. Junction boxes and pull boxes shall not be located in classrooms or offices unless there is an overriding design reason for doing so, dependent upon approval from CWU.

4.5.1.6 Surface Raceway

A. Surface raceway may be permissible in areas where no suitable alternatives exist. Surface raceway shall conform to bend radius requirements for Category 6 and fiber optic cable.

B. Surface raceway may be either plastic or metal. For Residence buildings,

surface plastic raceway shall not be used without permission from CWU on a project-by-project basis.


HORIZONTAL CABLING SYSTEMS

51

4.5.2 HORIZONTAL CABLING SYSTEMS

4.5.2.1 General

A. The Designer shall work with the CWU FP&CS Project Manager and the CWU ITS staff to identify and understand the needs and requirements for the facility on a project-by-project basis. This includes understanding the expected future uses of the facility. The Designer shall design the horizontal cabling accordingly.

B. CWU has standardized on the AMP Netconnect® Structured Cabling System

product line for inside plant copper telecommunications infrastructure. CWU has also standardized on the Corning Cable Systems LANscape® fiber optic cabling product line for all fiber optic cabling, both inside plant and outside plant. Therefore, telecommunications infrastructure designs and specifications shall be based upon these manufacturer’s products.

C. For the purposes of this document, references to Category 6 cable shall be

interpreted as AMP Netconnect® Category 6 UTP cable. D. In addition to the manufacturers listed above, CWU has selected several

manufacturers of products for telecommunications cabling systems (cable, connectors, termination blocks, patch panels, etc.) and telecommunications distribution hardware (racks, cable tray, enclosures, etc.). These manufacturers and their products are identified in the TCGS. The Designer shall incorporate only these manufacturers into the design, and shall design a telecommunications distribution system that will be suitable for the use of products from these manufacturers.

E. Generally, the eight-position pin/pair assignment for new cabling in new

construction shall be the T568A configuration. The T568B configuration shall only be used in the following two cases (but only after receiving written approval from the CWU ITS Infrastructure Specialist):

1. For new cabling in a new building on an existing site, when the T568A

configuration does not exist anywhere on the campus. 2. For new cabling added to existing cabling in an existing building, where

the existing cabling is to remain in operation and where the T568A configuration does not exist anywhere in that building.

In all other cases, new cabling shall be terminated using the T568A configuration.

F. Splitting of wire pairs degrades the performance of the split pairs and voids the AMP Netconnect® warranty.

1. Under no circumstances shall cable pairs be split or removed from the

back of a modular jack or patch panel. All four (4) pairs of each horizontal distribution cable must be terminated to a single eight (8)-position, eight (8)-conductor jack.



52

2. To support an additional telephone at a work area on existing cable, install an external line-splitting device on the outside of the faceplate and connect the additional cross-connect wires to the appropriate pins on the connecting blocks in the TR.

4.5.2.2 Horizontal Cross-connect (HC)

A. CWU has standardized on termination blocks for terminating horizontal telecommunications media. All horizontal cabling shall be terminated on 110 termination blocks, regardless of the intended use of the horizontal cabling, including cabling that will be used for voice, data or video.

B. The only exception is horizontal cabling serving Computer Labs which shall be

terminated on patch panels.

4.5.2.3 Horizontal Cable to Support Data Applications

A. At CWU facilities, horizontal distribution copper cable and components for data applications shall be rated-for and installed to support the IEEE 802.3ab 1000Base-T Gigabit Ethernet standard.

B. In new installations, horizontal cable supporting data applications (and all

other low voltage systems that are capable of operating with 24 AWG UTP copper cabling) shall be AMP Netconnect® 4-pair Category 6 cable. 1. Category 6 cables shall be terminated at the work area end with AMP

Netconnect® modular jacks. 2. Modular jack color shall be coordinated with CWU by the Designer.

C. In existing buildings, where additions are made to an existing Category 5 or

5E installation, the Designer shall seek direction from CWU regarding whether to install Category 5E or Category 6 cabling. If the number of additional cables to be installed is small compared to the installed base, CWU will likely wish to add new Category 5E cabling. On the contrary, if the number of new cables to be installed is relatively large, the additions shall be made using AMP Netconnect® Category 6 cable and matching components. Where Category 6 cabling is installed among other different cable types, the color of the Category 6 sheath shall be different from other existing cable. 1. Category 5 cable and components shall not be purchased or installed. 2. Category 5E or 6 cables shall be terminated at the work area end with an

AMP Netconnect® modular jack matching the category of the cabling. 3. Modular jack color shall be coordinated with CWU by the Designer.

4.5.2.4 Horizontal Cable to Support Voice Applications

A. Horizontal distribution cable intended to support voice services shall be the same AMP Netconnect® 4-pair Category 6 cable that is used for data applications. This cabling shall meet the same test requirements as cabling intended for data applications.

B. In existing buildings with Category 3 cabling serving voice applications, where

5 or fewer voice cables are to be added to the existing horizontal cabling



53

system, AMP Netconnect® 4-pair Category 3 cable or a Netconnect® approved substitute of equivalent or better performance are permissible.

1. If more than 5 voice cables are required, AMP Netconnect® 4-pair

Category 5E cable or Category 6 cable shall be used. The Designer shall request direction on this issue from the CWU ITS Infrastructure Specialist on a project-by-project basis.

4.5.2.5 Horizontal Cable to Support Serial Cabling Applications

A. CWU uses Category 6 cable for a number of applications that require serial telecommunications, including card access, point of sale, vending machines, laundry machines, etc. While these applications are not dependent on cabling that complies with ANSI/TIA/EIA 568B standards (in particular regarding cable length limits) it is desirable to comply with these standards wherever possible to provide the greatest degree of flexibility for future uses.

B. At the application end of the cable, the Designer shall require the Contractor

to provide a 50-foot coil for future termination by CWU, and the cable shall be left coiled in the nearest pathway or distribution point that will accommodate the coil.

C. At the TR end of the cable, the Category 6 cabling serving these applications

shall be terminated at the bottom of the termination block serving the floor of the building where the application end of the cable is located.

D. The Designer shall discuss the serial cabling requirements with CWU on a

project-by-project basis and shall expect each building to have unique requirements.

4.5.2.6 Horizontal Cable to Support Low Voltage and Building Automation Systems

A. During planning for intra-building telecommunications cabling installations, the Designer shall identify options for supporting power limited (low voltage) and building automation systems with the common structured cabling system, and present the options to CWU for consideration. These options shall comply with ANSI/TIA/EIA 862 – Building Automation Systems Cabling Standard for Commercial Buildings.

B. By providing a common cabling distribution system for the various building

automation systems, it may be possible to reduce construction costs and operational costs while creating an intelligent building that can contribute many other benefits (see TDMM Chapter 19 for further information). Low voltage systems that are capable of using a common structured cabling system (either backbone or horizontal cabling) shall be designed to use the AMP Netconnect® Structured Cabling System cable and termination hardware wherever possible.

C. The Designer shall request from CWU a list of systems that will require

telecommunications outlets for operations. The Designer shall then include outlets in the design as necessary to meet the listed requirements.



54

4.5.2.7 Patch Cords

A. Patch cords shall be AMP Netconnect® factory-manufactured patch cords. Patch cords shall be certified by the manufacturer to match the cable type used in the horizontal distribution.

1. Category 6 patch cords shall be used with all horizontal cabling

applications, regardless of its category rating. 2. Field connectorized patch cords are not acceptable. Any existing field-

connectorized patch cords used in areas affected by a project shall be replaced under the project with factory assembled Category 6 patch cords. See Table 4.2 below for information regarding the 110-block termination of patch cords.

B. The Designer shall quantify and specify the required patch cords in the

Contract Documents to be provided by the Contractor for each particular project, as shown in Table 4.2, below:

TABLE 4.2 PATCH CORD REQUIREMENTS

Patch Cord Applications

All Buildings Except Residence Halls

Residence Halls

Work Area Data Typically require CAT6 patch cords to be provided by the Contractor for each known immediate use plus 10% spare. This shall be confirmed with the CWU ITS Infrastructure Specialist on a case-by-case basis.

Do not require patch cords to be provided by the Contractor. Students will provide their own patch cords.

Work Area Voice Do not require patch cords to be provided by the Contractor. Patch cords are typically provided with telephone equipment.

Do not require patch cords to be provided by the Contractor. Students will provide their own patch cords.

Telecommunications Room Data

Require the Contractor to provide CAT6 patch cords, at least 30 feet in length. The Contractor shall be required to cut the patch cords in half and terminate the cut end of each patch cord on the 110-block for each data connection. The Contractor shall be required to connect the modular end of the patch cord to a network switch port, and shall route/groom the patch cords from the 110 blocks through the cable management to the network switches. For Academic buildings, require the Contractor to provide a quantity equal to the number of known immediate use requirements divided by two (cords will be cut in half) plus 5% spare patch cords.

For Residence Halls, CWU ITS may wish to “turn-up” all or just a portion of the ports. The Designer shall contact CWU ITS for direction. A possible formula for calculating the number of patch cords that the Contractor shall be required to provide is a quantity equal to the number of residents (at full capacity) divided by two (cords will be cut in half) plus 5% spare patch cords.

Telecommunications Room Voice

Jumper wire shall be provided by the Contractor for making cross-connections. No patch cords required.

DESIGN CRITERIA BACKBONE DISTRIBUTION SYSTEMS

INTRA-BUILDING BACKBONE PATHWAYS

55

4.6 BACKBONE DISTRIBUTION SYSTEMS

Please refer to the Backbone Distribution Systems section of the BICSI TDMM, the Pathways and Spaces section and the Cabling section of the BICSI CO-OSP, and the Installing Backbone Pathways section of the BICSI TCIM for general information regarding the design of backbone distribution pathway and cabling. The following requirements take precedence over the BICSI TDMM, the BICSI CO-OSP, and the BICSI TCIM guidelines for telecommunications infrastructure at CWU facilities:

4.6.1 INTRA-BUILDING BACKBONE PATHWAYS

A. Intra-building backbone pathway shall utilize a physical star topology. Backbone raceway shall consist of conduit, chases or shafts, sleeves, and/or ladder racking.

B. In new construction and full remodel projects, all telecommunications rooms

shall have a direct pathway connection to the main telecommunications room in the building (which typically serves as the entrance facility). Backbone pathways between two intermediate telecommunications rooms are generally not required.

1. For light remodel construction, it may be prudent (due to budgetary or

other project limitations) to design the intra-building backbone pathway in an arrangement that sub-feeds an intermediate telecommunications room from another intermediate telecommunications room.

2. Even though pathway from one telecommunications room may connect to

another telecommunications room before connecting to the main telecommunications room, backbone cabling shall not cross-connect in the interposing telecommunications room — intra-building backbone cabling shall be continuous (non-spliced) between the main telecommunications room and each intermediate telecommunications room.

4.6.1.1 Backbone Raceway Size and Quantity Requirements

A. Future growth requirements shall be considered when sizing intra-building backbone pathways. The cost to install additional spare pathways during initial construction is significantly less than the cost of retrofitting additional pathway in the future.

B. In general, for new construction and full remodel projects, CWU requires a

minimum of one 4” EMT conduit (or sleeve) and two spare 4” conduits (or sleeves) between the main telecommunications room/entrance facility and each intermediate telecommunications room.

4.6.1.1.1 Single-story buildings

A. For single-story buildings with multiple telecommunications rooms, 4” conduit pathways shall be routed through the ceiling, not in or under the floor slab. The Designer shall determine the number of 4” conduits required to serve initial and future backbone cabling requirements.


INTRA-BUILDING BACKBONE CABLING

56

1. In cases where it is not possible to route 4” conduits to each of the

telecommunications rooms, three 2” conduits may be substituted for each required 4” conduit.

4.6.1.1.2 Multi-story buildings

A. In new construction and full remodel projects, telecommunications rooms shall be stacked wherever possible. Sleeves may be substituted for conduit if the telecommunications rooms are stacked. Sleeved vertical pathways shall be extended to the roof (or to an attic space with access to the roof), to facilitate access for future roof or side-of-building mounted telecommunications equipment.

B. Ladder racking shall be vertically mounted in the stacked telecommunications

rooms to route and support backbone cable passing from the room below to upper rooms.

C. If design constraints prevent vertical stacking of telecommunications rooms, a

centrally located vertical pathway (chase) shall be provided and shall be dedicated to the telecommunications distribution system. This pathway shall have a minimum cross-sectional area of 2 ft2, shall be accessible at a maximum interval length of 3 feet, and shall extend to the roof or attic space. 1. 4” conduits shall be routed between the vertical chase and the

telecommunications rooms on each floor. The Designer shall determine the number of 4” conduits required to serve initial and future backbone cabling requirements.

2. In cases where it is not possible to route 4” conduits to each of the

telecommunications rooms from the vertical chase, three 2” conduits may be substituted for each required 4” conduit.

4.6.2 INTRA-BUILDING BACKBONE CABLING

4.6.2.1 Intra-building Backbone Cable Types

A. CWU uses three types of telecommunications cabling for intra-building backbone systems:

• 24 AWG UTP -- used for voice or analog applications • Multimode fiber optic, 62.5/125µm, graded index, extended grade (200

Mhz @ 850nm) – used for data and voice applications • Singlemode fiber optic – used for data, video, and voice applications

B. In addition, CWU occasionally uses Category 6 UTP for connections between

telecommunications rooms (or between telecommunications rooms and ER’s) that do not exceed 295 feet. This requires approval on a project-by-project basis.

C. CWU does not use 50/125µm multimode fiber optic cabling. CWU uses


INTER-BUILDING (CAMPUS) BACKBONE PATHWAYS

57

singlemode fiber wherever 62.5/125µm fiber is unable to meet the requirements of a particular application.

4.6.2.2 Strand and Pair Counts

A. Each telecommunications room shall be served with multimode fiber, singlemode fiber, and 24 AWG UTP copper intra-building backbone cables.

B. Backbone cable sizing (pairs / strands) shall be considered with respect to

possible future requirements. The cost to add additional backbone pairs and strands during the initial installation is significantly less than the cost of adding another cable in the future.

C. The minimum number of UTP backbone cable pairs to be provided shall be

equal to the number of horizontal cable ports served by the telecommunications room in which the port is terminated, plus one hundred percent expansion capability. At a minimum, require the Contractor to provide each telecommunications room with a 50-pair UTP cable.

D. The minimum number of multimode fiber optic strands to be provided shall be

equal to 2 strands per piece of equipment being hosted in the telecommunications room plus one hundred percent expansion capability. At a minimum, require the Contractor to provide each telecommunications room with a 12-strand multimode fiber optic cable.

E. The minimum number of singlemode fiber optic strands to be provided shall

be 12. Additional singlemode strands shall be considered on a project-by-project basis.

F. CWU permits the appropriate use of hybrid singlemode/multimode fiber optic

cabling, and allows both types of fiber to be terminated on separate bulkheads in a single fiber optic patch panel.

4.6.2.3 Cable Segregation

A. In no case shall copper or fiber optic backbone cabling be run in the same raceways as those used by electrical power conductors.

4.6.2.4 Innerduct

A. Intra-building fiber optic backbone cabling shall be designed using innerduct. B. The practice of populating a conduit with spare innerduct for future use is not

permitted.

4.6.3 INTER-BUILDING (CAMPUS) BACKBONE PATHWAYS

4.6.3.1 Telecommunications Outside Plant Pathway Master Plan

A. Each design for installation on the CWU campus is expected to conform to



58

and integrate with the CWU Telecommunications Outside Plant Pathway Master Plan. This plan provides a 10-year strategy for the use and expansion of the underground telecommunication pathways at the CWU campus.

B. The Master Plan divides the campus into nine areas, called “clusters.” Each

building within a cluster is connected via OSP telecommunications pathway (ductbank) to a building within the cluster that serves as the “cluster hub.” The cluster hub buildings are in turn connected via OSP telecommunications pathway to the Telecommunications Center, forming a standards-compliant two-level hierarchical star topology as shown the Figure below:

4.6.3.2 General Design Considerations

An OSP pathway system designed with attention to CWU’s standards and future needs provides for ease of administration, maintenance, future expansion, and replacement of cabling as technology changes. At the start of the project, the Designer shall request direction from CWU regarding the following aspects of an OSP pathway design: • Proposed pathway routing • Aesthetic requirements (exposed conduits on building walls, etc.) • Long range construction plans for buildings, paved areas, opens spaces, etc. • Any unique circumstances that may be specific to the project

4.6.3.3 Ductbank

4.6.3.3.1 Conduit Types

A. CWU requires 4” Schedule 40 PVC for all outside plant pathway except ducts serving Blue Light Emergency Telephones which shall be trade-size 1½” conduit.

B. OSP conduit shall transition from PVC to PVC-coated rigid steel conduit when



59

it enters within 10-feet of the building foundation and shall route from that point to the building entrance facility. PVC-coated, rigid steel conduit is intended to defend against the shearing effects of differential ground settling around the building foundation. It also increases the protection against future landscaping activities near the building.

• Transitioning back to PVC conduit after passing five feet inside the

building foundation is acceptable as long as the conduit remains in or under the slab, otherwise it shall transition to rigid galvanized steel conduit.

• The design shall require that a slack loop be installed inside the nearest

maintenance hole or handhole (not stored in the TR). The Designer shall require that sufficient racking hardware be provided in the maintenance hole or handhole to support the slack loop.

• The length of the loop shall be a minimum of 25 feet. The Designer shall

consider the arrangement of the telecommunications room and the possibility of a rearrangement that might consume the cable slack. If necessary, additional slack shall be required in the design, up to the NEC limit of 50 feet of exposed OSP-rated cabling.

• A maximum of fifty feet of outdoor-rated cable is permitted in a building

space. Therefore, rigid galvanized steel conduit shall be used to route the cable until will be it is close enough to its termination point that fifty feet or less outdoor-rated cable (including slack loops) will be exposed.

C. The use of flexible metallic conduit and flexible non-metallic conduit is

prohibited.

4.6.3.3.2 Burial Depth and Slope

A. Campus distribution conduits shall be buried a minimum of 30 inches deep. Where this minimum depth cannot be achieved due to physical constraints, approval for burial at an alternative depth may be requested through the ADR process.

• As an absolute requirement, conduits shall be buried beneath the frost

line. The Kittitas County Building and Construction Code 14.04.020 lists the frost line at 24 inches in Ellensburg. (See http://www.co.kittitas.wa.us/boc/countycode/title14.asp for further information.)

B. Conduit to be used for routing entrance cables from third party service

providers to an entrance facility shall be installed per the service providers’ requirements, generally 36 to 48 inches deep. The Designer shall consult with the service providers prior to designing conduits serving an entrance facility.

C. A continuous drain slope should exist at all points along the ductbank to allow

drainage and prevent the accumulation of water. • A drain slope of ¼” per foot is desirable where possible.



60

• Where ¼” per foot is not possible due to inadequate natural slope or long duct runs, a drain slope of no less than 1/8” per foot is acceptable.

• If no other option exists, require the Contractor to provide a “center crown” drain slope by sloping the first half of the ductbank up towards the midpoint, and then down from the midpoint to the end. Of course, the center crown technique can not be used for conduits between a maintenance hole and a building, because water would then drain into the building.

4.6.3.3.3 Conduit Sweeps (Bends)

A. CWU has standardized on the use of factory-manufactured sweeps with a minimum bend radius of 48” for all OSP ductbanks with the following exceptions and alternatives:

• Shallow curves comprised of continuous lengths of individual straight RNC

conduit are permissible with a minimum sweep radius of 40 feet. • Where cabling larger than 400-PR UTP copper is intended to be installed,

conduit bends shall have a radius larger than 48”. The Designer shall consult with the CWU ITS Infrastructure Specialist on a case-by-case basis to select appropriately-sized conduit sweeps.

B. The Designer shall minimize the effects of sidewall pressure between the

cable and conduit at bend points where possible by designing bends with the most tightest bend radii to be near the cable feed end of the duct section rather than the middle or end of the duct bank.

4.6.3.3.4 Concrete Encasement

CWU has standardized on concrete encasement with full length reinforcement and formed sides for all ductbanks except ducts serving Blue Light Emergency Telephones which shall not be encased in concrete. A. Prior to concrete being poured, the CWU ITS Infrastructure Specialist or a

designated representative shall observe the OSP conduit installation to identify unacceptable installations that need to be corrected prior to concrete encasement.

B. In general, direct-buried conduit ductbanks are not permissible, unless

extenuating circumstances warrant and approved by CWU through the ADR process. Should the use of direct-buried conduit ductbank be warranted, the Designer shall ensure that all bends in the ductbanks are encased in concrete.

4.6.3.3.5 Number of Ducts

A. The OSP pathway system shall accommodate the requirements for signal and low voltage cabling systems at CWU facilities. The Designer shall inquire with CWU staff about the potential for future buildings or building expansions that may adversely affect an existing or proposed distribution pathway and accommodate those plans within the design.



61

B. The number of ducts in a ductbank should meet the needs of the specific application and should offer future expansion capability. The following list is a guideline for consideration when designing a new ductbank.

• Small utility buildings up to 5,000 sq. ft.: 2 ducts (approvable on a case-

by-case basis) • Buildings up to 100,000 sq. ft.: 4 ducts • Buildings 100,000 sq. ft. to 300,000 sq. ft.: 6 ducts • Buildings larger than 300,000 sq. ft.: multiple redundant entrances with 6

ducts each • Building serving as a Cluster Hub Building: 6 ducts • Pathway between Cluster Hub Buildings and the Telecommunications

Center: 4 ducts

4.6.3.3.6 Ductbank Length

A. In general, ductbank systems shall be designed with section lengths averaging 400 feet and as straight as possible.

B. The maximum permissible ductbank length (between maintenance holes

and/or buildings) is 600 ft. Ductbank runs that exceed this distance require intermediate maintenance holes or handholes. This requirement may be waived through the ADR process in rare cases having the following conditions: • The duct run is straight. • The Designer can demonstrate that the pulling tension of several typical

OSP telecommunications cable types will not be exceeded during installation.

4.6.3.3.7 Separation from Other Utilities

A. In general, ductbank used as pathway for telecommunications and other low voltage cabling should not be routed with other utilities. Budgetary constraints, space limitations, and various obstructions can make this difficult to achieve at times. Should shared routing be a necessity (perhaps for overbuild construction projects), the Designer shall ensure that adequate separation exists between ducts used for telecommunications and ducts used for other utilities.

B. The pathway system shall be designed such that telecommunications and

other low voltage systems do not share conduits, maintenance holes, handholes or tunnels with the electrical power distribution system. The telecommunications distribution pathway shall also maintain minimum separation distances from electrical power distribution infrastructure as required by CWU.

The vertical and horizontal separation requirements for OSP telecommunications pathways from other underground utility infrastructure are as follows:

4.6.3.3.7.1 PROXIMITY TO POWER OR OTHER FOREIGN CONDUITS

NESC requirements state that outside plant telecommunications conduits shall not be installed closer to power conduits or other unidentified underground conduits than:



62

o 3” where the surrounding material is concrete o 4” where the surrounding material is masonry o 12” where the surrounding material is well-tamped earth The NESC requirements above are focused on safety issues, and the performance of telecommunications systems can be negatively affected by the presence of nearby sources of EMI, even though the NESC safety-related separation requirements are met. Where the Designer is concerned about EMI due to the proximity of power distribution infrastructure, the Designer shall discuss the issue with the CWU ITS Infrastructure Specialist.

4.6.3.3.7.2 PROXIMITY TO WATER, GAS OR OIL CONDUITS

Outside plant telecommunications conduits shall not be installed closer to conduits that can be identified as not containing electrical power distribution conductors than: o 6” where the conduits cross o 12” where the conduits run in parallel with each other Telecommunications conduits running in parallel with water, gas or oil conduits shall not be installed vertically above the other conduits, but rather to the side of the conduits. This arrangement should contribute to decreased disruption to the telecommunications conduits in the event of excavation maintenance activities associated with the other nearby conduits.

4.6.3.3.7.3 PROXIMITY TO STEAM LINES AND STEAM UTILIDORS

A. A minimum separation distance of 12” is required between a steam utilidor and telecommunications conduits.

B. Steam lines pose two primary risks to telecommunications cabling:

• Under steady state operating conditions, objects in the vicinity of steam lines may warm due to heat lost through the insulation of the steam line. As the temperature of telecommunications cabling increases, its performance can degrade. In situations where there is concern about the risk of exposure to steady state heat, the separation distance between the steam line and telecommunications infrastructure shall be increased.

• In the event of a steam line failure in the proximity of telecommunications

infrastructure, significant damage to the conduits and cabling can result from the high temperature steam. In situations where there is concern about the risk of exposure to high temperatures from steam line failure events, the design shall require telecommunications conduits shall be encased within an insulating sleeve in the vicinity of the risk.

C. High temperature insulation may be necessary to protect telecommunications

conduits and cabling. D. CWU’s practice is to install steam lines in utilidors, rather than to direct-bury

the steam lines. The utilidors are typically 3 to 4 feet high, and may be buried with 0 to 2 feet of surface cover. Therefore, the bottom of most utilidors on campus is typically somewhere between 3 and 6 feet deep.



63

E. The Designer shall field-investigate the actual utilidor routing in cooperation

with CWU surveying staff to identify accurate field conditions. Potholing to confirm record drawing information is typically required.

F. Where physical conditions appear to preclude compliance with the following

requirements, an Alternative Design Request shall be submitted demonstrating solutions for mitigating exposure to worse-case conditions, including steam line failure where steam vents in the direction of the telecommunications conduits.

4.6.3.3.7.3.1 Crossing Above Steam Utilidors

A. Due to the requirement to bury conduit beneath the frost line, a cover depth

of 43 inches is required for a topside conduit crossing. Unless a utilidor has at least this much topside cover, it will not be possible to install a single-level conduit ductbank over the top of the utilidor while maintaining 12” separation from the top of the utilidor and while keeping the conduit below the frost line.

• It is unlikely that a circumstance permitting a topside crossing will occur

at CWU. B. Telecommunications ductbanks shall not cross over the top of a steam utilidor

in a live load area where vehicle traffic passes without specific CWU approval.

4.6.3.3.7.3.2 Crossing Beneath Steam Utilidors A. Most commonly, where telecommunications conduits must cross a steam

utilidor, the conduits must cross underneath the utilidor. Care shall be taken to avoid creating a dip in the conduit at this point where water will collect – the conduit slope shall be designed to permit any water entering the conduits to drain out. The following diagram depicts this concept:

B. The Designer shall design a utilidor crossing similar to the pre-approved



64

solution shown in the diagram above or some other solution that accomplishes a utilidor crossing without trapped water and without risking cable damage due to nearby steam heat. The Designer shall include details of any steam utilidor crossings in the Construction Documents.

4.6.3.3.7.3.3 Direct Buried Steam Lines

A. If it becomes necessary to install telecommunications conduits in the vicinity

of direct-buried steam lines, the following requirements apply:

• Telecommunications conduits shall not be installed closer than 12 inches to steam lines, and shall perpendicularly cross the steam lines.

• Direct-buried steam lines within 12 to 24 inches of telecommunications conduits shall be encased with an insulated pipe sleeve surrounding the steam line. The sleeve shall be constructed from a material designed to withstand steam temperatures and protect against physical/mechanical damage from jets of steam. The insulated sleeve shall extend at least 5 feet on both sides of the crossing point of the telecommunications conduits.

4.6.3.3.8 Innerduct

A. While OSP innerduct for fiber optic cabling has been used on past CWU telecommunications projects, CWU no longer installs innerduct on its projects unless the application specifically requires it.

B. In the event that OSP innerduct is needed, sufficient innerduct to meet the

needs shall be designed into the project. However, spare innerduct shall not be included.

4.6.3.3.9 Coordination with Utility Service Providers

The Designer shall inquire with CWU to determine whether services from utility service providers will be necessary. If so, the Designer shall contact the utilities to obtain their entrance pathway, entrance facility and demarcation point requirements.

4.6.3.4 Maintenance Holes and Handholes

A. Typically, maintenance holes are installed for main ductbanks (i.e. ductbanks used for routing large portions of the telecommunications system backbone), and handholes/pullholes are installed for subsidiary ductbanks (i.e. ductbanks serving small clusters of buildings or a single building).

B. Maintenance holes and their covers shall be appropriately sized for the

application.

• Covers for maintenance holes and handholes shall be either lockable or use bolts to prevent unauthorized access.

• Diamond plate hinged covers and removable diamond plate covers are not

permitted for maintenance holes at CWU.



65

C. Telecommunications maintenance holes and handholes shall not be shared with electrical power distribution infrastructure. In general, powered devices should not be located in telecommunications maintenance holes and handholes.

D. The number of duct entrances in a maintenance hole or handhole should be

sized for both immediate and future requirements. Also, splayed duct entrance arrangements are preferred over center entrances.

• It is desirable to have ducts enter and exit from opposite ends of a

maintenance hole or handhole. Sidewall duct entrances should be avoided because such entrances may obstruct racking space, may cause cable bends to exceed limits, may interfere with cable maintenance activities, and may increase construction costs during cable installation.

• CWU recognizes that sidewall duct entry may be necessary or desirable in

some circumstances. In these cases, sidewall ducts shall enter and exit at diagonally opposite corners - ducts shall not enter and exit at the midpoints of the endwalls or sidewalls. The Designer shall ensure that endwall and sidewall duct entry in a maintenance hole or handhole will not hinder the proper installation and maintenance of cabling.

E. Ducts shall be designed to enter the maintenance holes and handholes

starting at the lowest conduit knockouts and moving upward, preserving remaining knockouts accessible for future conduit additions. The Designer shall design the duct entrances such that the relative position of each duct does not change as it enters and exits the maintenance hole or handhole. Also, the Designer shall endeavor to design ductbank arrangements so that the conduits enter and exit a sequence of maintenance holes or handholes in the same relative positions.

F. Splices in backbone fiber optic cable are not allowed, and while splices in

backbone copper cable may be permitted in some rare cases (through an approved ADR), they are discouraged. However, when sizing OSP telecommunications maintenance holes, the design shall require the Contractor to provide space for possible future splice closures when required (for example, to repair cable breaks when and if possible).

G. Some situations may require placement of maintenance holes at below-typical

depths. In such cases, the top of the maintenance hole shall be placed at normal depth and the height of maintenance hole shall increased through the use of intermediate riser extensions between the base and the top. CWU wishes to avoid deep-collar entrance portals to improve lighting and ventilation wherever possible. Where the collar will exceed 24” in height, the Designer shall require that the collar be equipped with permanently affixed galvanized steps (rungs).

4.6.3.5 Aerial Distribution

Aerial distribution of telecommunications cabling at CWU facilities is not authorized. If an application requires aerial distribution, permission to use this method shall be


CAMPUS CABLING

66

requested through the “Alternative Design Request” process.

4.6.3.6 Bridge and Waterway Crossings

The Designer shall review the construction of bridge and waterway crossing distribution systems for compliance with the design. The design and installation shall also be reviewed, approved, and inspected by the CWU ITS Infrastructure Specialist or designee.

4.6.3.7 Wireless and Radio System Distribution

A. CWU facilities frequently use wireless or radio systems for telecommunications with mobile units and personnel, both on and off of the campus. These systems typically use one or more radio antennas connected by cabling to radio transceiver equipment. In some cases, the radio equipment may be interfaced into the telephone system. The outside plant telecommunications substructure shall be designed with adequate cable routing pathways between antenna locations, radio transceiver locations, and the telephone backbone cabling system.

B. Radio antenna transmission cables that connect the antenna to the radio

transceiver emit radio frequency (RF) radiation. These cables may be routed through the common telecommunications ductbank and maintenance hole system if necessary, but shall be routed in a separate conduit from other telecommunications cables. Cables containing RF radiation shall be shielded cables.

C. Radio interconnection cables (for analog or digital signaling to remote radio

operating positions or to the telephone system) typically emit low levels of radio frequency radiation. These interconnection cables shall be routed through the common telecommunications ductbank and maintenance hole system. Individual conduits may be shared for these interconnection cables and other telecommunications services, and available cable pairs in telephone backbone cables may be used for these interconnections, provided that the signaling is analog or digital signaling, and is not direct radio frequency signal.

4.6.4 CAMPUS CABLING

4.6.4.1 General

A. CWU uses three types of telecommunications media for the campus backbone system:

• 24 AWG UTP (copper) – used for voice, analog signaling, and various

metering applications • Singlemode Fiber Optic – used for data, video, and increasingly, voice

applications • 62.5/125 um Multimode Fiber Optic – used primarily for data applications

and various metering applications.


CAMPUS CABLING

67

CWU does not use 50/125µm multimode fiber optic cabling on campus. CWU uses singlemode fiber wherever the existing 62.5/125µm fiber is unable to meet the requirements of a particular application.

B. Each building shall be provided with the above three types of

telecommunications media. C. As discussed in the Preface section of this document, telecommunications

distribution systems designed for CWU facilities are expected to support and integrate all low voltage, power limited signal systems and Building Automation Systems that convey information within and between buildings wherever practicable.

• During planning of backbone cable installations, the opportunity for these

systems to use the common structured cabling system shall be evaluated by the Designer and discussed with CWU. The backbone cabling design shall reflect the needs and requirements identified during these discussions.

D. Where cables are to be pulled through maintenance holes and handholes, the

duct selected for cable installation shall be the same as it enters and exits the maintenance hole or handhole. Changes in duct selections, especially in elevations, should be avoided to reduce the risk of damage to cable sheaths and to minimize pulling tension.

E. Ducts shall be assigned during the course of design, not during construction.

Duct assignments must be approved by CWU prior to the release of construction documents. If a choice of ducts to use is available, the bottom ducts should be used first in order to facilitate future cable placement.

F. Cabling entering a building should be routed so as not to block or obstruct the

planned usage or expansion of any other facility that occupies or will occupy the space.

G. Telecommunications backbone cables shall be segregated by type of cable

(fiber optic, copper, coaxial, other). Segregation can be accomplished by using different ducts (the most desirable solution), or by using separate innerducts within the same duct. Segregation is desirable because when maintenance work is performed on a backbone cable serving a specific system, work on that cable will not disrupt the functionality of other backbone cables serving other systems.

H. OSP cable shall be installed in the lowest available conduit in a ductbank,

working up as additional cables are installed. I. The use of direct buried cabling and aerial cabling is not authorized. If

circumstances appear to justify either of these cable distribution methods, the Designer shall seek approval via the Alternative Design Request process.


CAMPUS CABLING

68

4.6.4.2 Copper Backbone Cabling

A. Outside plant copper backbone cabling shall be 24 AWG UTP cabling. B. CWU requires that copper backbone cabling be designed and installed in an

unspliced, home-run configuration.

• For copper cabling, indoor dry splice enclosures shall be provided just prior to the building entrance terminals.

• For long cable runs, the longest cable reel lengths obtainable shall be

used. Splices shall not be used except where cable reel lengths are exceeded. If splices are used, the Designer shall ensure that the splice location will have enough space for storing cable slack loops after the splice is completed.

• The Designer shall design OSP copper backbone cabling such that it does

not exceed 2,200 feet in length. This is the length limitation for the digital telephone sets used on campus. Where a project appears to require lengths longer than this amount, the Designer shall alert the CWU ITS Infrastructure Specialist to cooperatively consider other options, including the use of fiber optic cabling with remote telephone system electronics.

C. Typically, CWU uses OSP copper cabling that is “outdoor-only” rated for its

inter-building copper needs.

• At most end-use buildings, OSP copper cabling is spliced immediately upon entrance into the building, transitioning to smaller pair-count, indoor-rated cabling.

• At the Computer Center, OSP copper cabling is spliced in maintenance

hole G11O02 (just prior to entering the building) and is transitioned to smaller pair-count OSP-rated cabling, and then it is terminated within the 50-foot length limitation immediately inside the building. Slack loops are stored in the maintenance hole.

D. Inter-building copper backbone cables shall be terminated with a primary

protector panel at each cable end. The protector units shall provide sneak-current protection. Building entrance terminals shall be grounded to the building electrical power ground.

E. Twisted-pair copper cabling shall not be used for inter-building data backbone

applications.

F. Pressurized cabling and associated pressurization systems shall not be used at CWU facilities.

4.6.4.2.1 OSP Copper Pair Counts

A. Copper backbone cables shall be sized to support two pairs per work area, plus 25% growth. When calculating size, work area shall also include fax machines and dial-up modems. Copper backbone cables shall have a


CAMPUS CABLING

69

minimum of 25 pairs. B. Backbone cable pair sizing shall be considered with respect to possible future

requirements. The cost to add additional backbone pairs during the initial installation is significantly less than the cost of adding another cable in the future. • CWU uses fiber optic cabling for voice applications at some of its buildings.

The Designer shall inquire about whether fiber or copper cabling is to be used for voice services at a facility, and shall size the copper cabling accordingly.

4.6.4.3 Fiber Optic Backbone Cabling

A. During the Design Development phase, the Designer shall contact Corning Cable Systems fiber optic cable suppliers and obtain their projections of the lead-time requirements for fiber optic cabling. This information shall be submitted to CWU ITS to aid project-scheduling efforts and determine whether cable should be pre-ordered.

B. OSP fiber optic cable installed underground shall be loose tube construction

and gel-filled or be constructed of appropriate waterproofing compounds. C. CWU does not permit the design of any fiber optic cabling system that is

dependent on splices.

D. Typically, CWU uses OSP fiber optic cabling that is “Indoor/Outdoor” rated (Corning Cable Systems’ “Freedm” line of products) for most of its inter-building fiber needs. The reason for this choice is that many (if not most) of the buildings on campus do not have a continuous metallic conduit from the point of entry to the main telecommunications room in the building and the length of the entrance cable typically exceeds 50 feet. This solution also preserves signal headroom that would be lost crossing a spliced Outdoor-to-Indoor rated cabling transition point.

E. Wherever appropriate, designs shall require hybrid singlemode/multimode

fiber optic cabling. Both types of fiber shall be terminated on separate bulkheads in a single fiber optic patch panel.

F. The Designer shall consult with the CWU ITS Infrastructure Specialist prior to

developing the fiber optic design to determine the performance requirements for the network electronics. Selection of fiber optic interface modules for network electronics will be affected by the lengths of the fiber optic cabling to be used by the electronics.

G. Fiber optic cabling shall be terminated in rack-mounted patch panels. On

approval from CWU ITS, fiber may alternatively be terminated in wall-mountable connector housings secured to a plywood backboard.

1. Where equipment racks are installed, the rack-mountable Fiber Optic

Interconnection Units shall be used. 2. The standard fiber optic connector for CWU is the type 568SC Duplex.


CAMPUS CABLING

70

When fiber additions are made to existing facilities where type 568ST connectors are in use, new 568SC Duplex connectors and new Duplex SC patch panels shall be used for new fiber.

3. For full remodel and light remodel to existing facilities where type 568ST connectors are currently in use, CWU may wish to re-terminate the existing fiber and install 568SC Duplex connectors. The Designer shall inquire with CWU ITS for direction with this issue on a project-by-project basis.

4. All strands of a fiber optic cable shall be terminated using fusion-spliced pigtail connectors. The installation of “dark fiber” is not permitted.

H. Fiber optic cable and components shall be rated and installed to comply with

the IEEE 802.3z 1000Mb/s (Gigabit Ethernet) standard. CWU networks operate at Gigabit backbone speeds.

I. In new construction and new conduit, fiber optic backbone cables shall be

installed in fiber optic innerduct that routes continuously to each telecommunications rack or backboard location where the fiber is terminated. Where fiber optic cable is installed into existing conduits, the use of fiber optic innerduct is required if space is available. Design or installation of fiber optic cabling without the use of innerduct shall require approval through the “Alternative Design Request” process.

4.6.4.3.1 OSP Fiber Strand Counts

A. In accordance with the CWU Telecommunications Outside Plant Master Plan, the following guidelines should be considered when determining appropriate strand counts for each type of cabling to be installed:

• Between Cluster Hub Buildings and other buildings in the cluster:

Cable Type Strands Usage Singlemode Fiber 12 strands 4 Data, 4 Video, 4 Spare Multimode Fiber 24 strands 4 Data, 2 Access Control, 4 Fire Alarm, 2 HVAC

Control, 2 Power Metering, 10 Spare

• Between Cluster Hub Buildings and the Computer Center:

Cable Type Strands Singlemode Fiber 48 strands Multimode Fiber 24 strands

4.6.4.3.2 Fiber Optic Patch Cords

A. Fiber optic patch cables shall be factory manufactured Corning Cable Systems cables • Fiber optic patch cables shall interconnect with the site backbone using

Duplex SC connectors. If low voltage equipment is not available with SC connectors, then hybrid fiber patch cables from Corning Cable Systems shall be used.

B. Mode-conditioning patch cords shall be used for 1000BASE-LX runs over


CAMPUS CABLING

71

multimode fiber optic cable where the length is between 275 meters and 550 meters: • Between the work area outlet and the LANattached device. • Between the TR patch panel and the LAN switch.

4.6.4.4 Services Distributed via OSP Cabling

At CWU, the various services carried via OSP cabling are distributed differently depending on the type of service and the type of building as described below. These issues may affect the cabling to be installed on a project.

4.6.4.4.1 Administrative/Academic Telephone Services

A. Telephone services are generally provided centrally at the Computer Center and then distributed campus-wide to campus buildings via the OSP cabling infrastructure.

B. CWU uses Voice-over IP (VOIP) on campus where it is justified. Where VOIP

is used, it is distributed via fiber to each building rather than copper backbone cabling.

• The Designer shall inquire on a project-by-project basis whether fiber for

VOIP or whether copper-based telephone services will be provided, which may affect the number of fiber strands and copper pairs to be installed.

4.6.4.4.2 Student Telephone Services

A. Student telephone services are generally provided directly to each residential building by Ellensburg Telephone. Each residential building has its own demarc. Recently, however, CWU has provided analog voice services using CWU’s PBX to students in Kamola and Sue Lombard via copper OSP cabling.

• The Designer shall inquire on a project-by-project basis whether CWU will

provide telephone services for a Residence Hall or whether it will be necessary to coordinate with Ellensburg Telephone to provide telephone services.

B. At this point, CWU intends to continue using standard analog telephone for

student residences. There is no intention to use VOIP for students.

4.6.4.4.3 Administrative/Academic Cable Television Services

Cable television services are generally provided centrally at the Library building (Media Equipment Services) and then distributed campus-wide to campus buildings via the coaxial and fiber optic OSP cabling infrastructure. • The Designer shall inquire on a project-by-project basis whether OSP coaxial

cabling, OSP fiber optic cabling or ISP coaxial cabling will be required under the project for television distribution to a building.

DESIGN CRITERIA TELECOMMUNICATIONS ROOMS AND ENCLOSURES

TELECOMMUNICATIONS ROOM LOCATION

72

4.6.4.4.4 Student Cable Television Services

Student cable television services are generally provided directly to each residential building by Charter Telecommunications. Each residential building has its own television demarc locations, and the utility provides its own OSP service cable to the building. • The Designer shall inquire on a project-by-project basis whether coordination

with the utility is required and whether inside plant coaxial cabling will be required under the project for cable television distribution inside the building.

4.6.4.4.5 Campus Network and Internet Services

Network and Internet services are generally provided centrally at the Computer Center and then distributed campus-wide to campus buildings via the OSP cabling infrastructure.

4.7 TELECOMMUNICATIONS ROOMS AND ENCLOSURES

Please refer to the Telecommunications Rooms and Enclosures section of the BICSI TDMM for general information regarding the design of telecommunications rooms. The following requirements take precedence over the BICSI TDMM guidelines for telecommunications infrastructure at CWU facilities: A. In CWU facilities, the TRs in a building may also serve as low voltage systems

equipment rooms, typically containing electronic equipment intended to serve the building or a portion of the building. The TR shall not be shared with electrical installations other than those necessary for telecommunications.

B. Telecommunications rooms that contain intermediate cross-connects (IC’s),

while recognized by the ANSI/TIA/EIA standards, shall not be utilized. IC’s contribute significantly to the total cost of ownership for a system and therefore are not allowed by CWU.

4.7.1 TELECOMMUNICATIONS ROOM LOCATION

A. The Designer shall be responsible to inform the Architect of the sizing and location requirements for Telecommunications Rooms during the Schematic Design phase of the project.

B. The most desirable location for telecommunications rooms is to be located as

centrally and as closely as possible to the area being served. In addition, for multi-story buildings, telecommunications spaces shall be vertically aligned wherever possible. This allows for clean, vertical pathway to be easily provided to each space. It also reduces the number of bends and offsets that the intra-building backbone pathway must undergo as it connects each of the telecommunications rooms. In light remodel projects, this requirement may be waived due to budget or space availability limitations. Please see the discussion in the Intra-building Backbone Pathways section in this document for further information.


TELECOMMUNICATIONS ROOM SIZING

73

C. There shall be a minimum of one TR per building. Additional TRs shall be added when the area to be served exceeds 10,000 square feet or where the cable lengths will exceed 295 feet between a TR and the work area telecommunications outlet, including allowance for cable slack loops. Generally, each floor of a building shall be served by a TR located on that floor.

D. Telecommunications Rooms shall not be co-located with any type of electrical

room, mechanical room, and shall not be located directly adjacent to these rooms. The TR location shall maintain the separation distances identified in the Electromagnetic Compatibility subsection of this document.

4.7.1.1 TRs Serving Computer Labs

A. Prior to starting a cabling design for a computer lab, the Designer shall meet with CWU to determine whether to follow the CWU-standard practice of using termination blocks for terminating horizontal cabling (see Horizontal Cross-connects (HC), below), or whether a small rack-mounted Category 6 patch panel system is desired for terminating horizontal cabling serving the computer lab. A patch panel system might give the Instructor more flexibility in configuring the lab network, as well as the ability to easily disconnect the computer lab network from the building network when required. This issue will be addressed on a case-by-case basis.

B. There are two options for a cabling and equipment rack serving a computer

lab. In either case, the rack shall be provided with standard intra-building backbone cabling.

1. An enclosed, lockable cabinet (either free-standing or wall-mounted)

located within the computer lab. 2. A free-standing rack or wall-mounted swing rack located in a small

telecommunications room adjoining and dedicated to the computer lab.

4.7.2 TELECOMMUNICATIONS ROOM SIZING

A. Inadequately sized telecommunications spaces are generally not acceptable. However, reach-in closets and small room designs for light remodel construction projects may be considered through the ADR process.

B. Telecommunications room sizing shall be increased if other low voltage

systems equipment is intended to be hosted in the TR, for example fire alarm panels, security system equipment, etc. The Designer shall seek input from the CWU ITS Infrastructure Specialist regarding room sizing.

4.7.3 ARCHITECTURAL PROVISIONING

A. The Designer shall be responsible to inform the Architect of the architectural provisioning requirements for Telecommunications Rooms and to do this early in the Design Development phase of the project.


ENVIRONMENTAL PROVISIONING

74

B. The Designer shall be responsible to review project documents and determine that the architectural requirements for the telecommunications spaces are met as described in this document. For projects where an architect is involved, the Designer shall coordinate directly with the architect, and verify that the architect’s design documentation meets these requirements. For projects without an architect, the Designer shall alert CWU where additional architectural adjustments are needed to meet the requirements.

C. Doors shall open out from telecommunications spaces wherever possible and

shall be a minimum of 36” wide and 80” high, fitted with a lock. Coordinate lock and key requirements with CWU. Doors shall be located in hallways or other common areas. Telecommunications room doors shall never be located in another building occupant’s designated space.

D. Minimum clearance height within a telecommunications space shall be 8 feet.

False ceilings (t-bar ceilings, ceiling grids, etc.) shall not be installed in telecommunications spaces. The floor, walls, and ceiling shall be sealed to reduce dust.

E. Finishes shall be light in color to enhance room lighting. Flooring materials

shall be light colored, fire retardant and slip resistant — carpet is not acceptable for telecommunications rooms.

F. The walls in telecommunications rooms shall be covered with plywood

backboards. The plywood shall be painted with two coats of white, fire retardant paint. The plywood shall not be fire retardant (fire retardant paint tends to flake off of fire retardant plywood).

• Plywood backboards shall extend from the floor to a height of eight feet

above the finished floor. • In TRs where the power conduits are retrofitted in a surface mounted

fashion, it may be convenient to mount the plywood at a height of 6” above the finished floor, extending to 8’6” above the finished floor. The 6” space below the backboard can then be used to route the power conduits to the outlets without obstructing plywood backboard space.

4.7.4 ENVIRONMENTAL PROVISIONING

A. The Designer shall be responsible to inform the Mechanical Engineer of the environmental provisioning requirements for Telecommunications Rooms and to do this early in the Design Development phase of the project.

B. The Designer shall be responsible to determine that the mechanical (HVAC,

fire suppression, etc.) requirements for the telecommunications spaces are met as described in this document. For projects where a Mechanical Engineer is involved, the Designer shall coordinate directly with the engineer, and verify that the engineer’s design documentation meets these requirements. For projects without the involvement of a Mechanical Engineer, the Designer shall alert CWU where adjustments to the mechanical infrastructure are needed to meet the requirements.


FLOOR-STANDING EQUIPMENT RACKS AND CABINETS

75

C. The Designer shall coordinate with the Mechanical Engineer to ensure that the

HVAC requirements for the telecommunications spaces are met and also that HVAC ductwork and motors do not conflict with cable tray or conduit routing.

D. In addition to the requirements in the BICSI TDMM, telecommunications

rooms shall be environmentally provisioned as follows:

1. A fundamental design assumption is that all TRs will at some time contain active electronic equipment (hubs, routers, switches, etc.) even if the current design does not call for such devices. Network electronics require an HVAC system capable of operating on a 24 hours-per-day, 365 days-per-year basis. If the building system cannot assure continuous cooling operation, a stand-alone unit shall be provided for the TR. In addition, a positive pressure differential with respect to surrounding areas is required to help keep dust and other particles out of the room.

2. Minimum clearance height in the TR shall be eight feet without

obstructions. 3. Fire suppression system sprinklers shall be equipped with wire cages

under the sprinkler heads to prevent accidental discharge. Drainage troughs shall be placed under sprinkler pipes to prevent leakage onto the equipment within the room.

4.7.5 FLOOR-STANDING EQUIPMENT RACKS AND CABINETS

A. Each telecommunications room shall be provisioned with a minimum of one floor-standing 7’ high x 19” wide ANSI/TIA/EIA standard open-frame equipment rack, regardless of whether or not equipment is required at the time of construction.

• For light remodel construction, this requirement may be waived given

budget, project size, or other limiting factors. The use of a wall-mounted swing rack or a wall-mounted hinged bracket may be acceptable, subject to CWU approval via the ADR process.

B. 36” clearances are required surrounding racks, cabinets and any equipment

that may be mounted in the racks, as required by code. See the sample telecommunications room plan drawing in the Appendix for further information.

C. Racks shall be sized to accommodate, at a minimum, all existing and new

equipment that is to be installed in the rack plus an additional 50% of space for additional equipment that may be added in the future. If a rack is more than 50% full at design time, a spare rack shall be specified.

4.7.5.1 Floor-standing Equipment Racks

A. Floor standing racks shall be securely bolted to the floor, and shall be braced to the wall with cable ladder racking. Multiple racks in the same TR shall be


FLOOR-STANDING EQUIPMENT RACKS AND CABINETS

76

interconnected with cable ladder racks. B. To provide the required clearances, rack locations shall be designed to have

72” of clear space between the front of the rack and the wall behind the rack. Also, a workspace access clearance of 36” is required on one side of an aisle of racks. The Designer shall discuss with CWU the potential for future requirements for additional racks, and identify spaces for future racks on the plan drawings. See the sample telecommunications room plan drawing in the Appendix for further information.

C. Racks shall be equipped with horizontal and vertical wire management

modules both front and rear with strain relief brackets to support proper cable bend radius and to maintain strain relief for the cabling.

D. Some IT equipment requires an equipment rack with both front and rear

mounting rails. The Designer shall discuss with CWU the network electronics that will be hosted in each rack in each TR and shall show this equipment on the rack elevation details in the plan drawings.

4.7.5.2 Telecommunications Cabinets

A. When planning the size and location of TRs in existing buildings, the Designer shall make every reasonable effort to meet the requirements for telecommunications rooms. In certain instances, the only viable alternative may be the use of one or several telecommunications cabinets in lieu of TRs.

B. In light remodel projects, some buildings may not justify a separate room as

the telecommunications room. In some circumstances, sufficient space may not be available for a telecommunications room. In these instances, a wall-mounted or floor-standing telecommunications cabinet may be used.

C. Wall-mounted cabinets shall be double-hinged to permit access to both the

front and rear of the equipment. Care shall be taken to specify cabinets with strong hinges that do not begin to sag over time due to the weight of the cabinet’s contents. Telecommunications cabinets shall be constructed of heavy gauge steel, and be lockable.

D. Cabinets shall be sized to allocate space for cabling termination infrastructure,

network electronics, and UPS equipment, and shall also include space allocated for future growth. Wall space shall be allocated to permit cabinets to fully swing open.

E. Cabinets shall be equipped with horizontal wire management modules with

strain relief brackets to support proper cable bend radius and to maintain strain relief for the cabling.

F. Power and telecommunications cables for equipment housed within the

cabinet are to be contained within the cabinet. Exposed wiring or cables are not permitted. Power and telecommunications cables routed to or from the cabinet shall be contained in conduit, surface mounted raceway, or concealed within the adjacent wall.

G. Each cabinet shall be vented and shall be equipped with cooling fans. Vent

filters shall be provided wherever appropriate to minimize the entrance of dust and foreign materials.

H. Each cabinet shall have a telecommunications main grounding busbar (TMGB)

installed inside, in accordance with the grounding requirements discussed in Chapter 17 of the BICSI TDMM.

I. The cabinet shall not be located in or adjacent to areas containing sources of

electromagnetic interference (EMI). See the Electromagnetic Compatibility section (above) for further information.

4.7.6 POWER REQUIREMENTS

A. The Designer shall be responsible to determine that the power requirements for the telecommunications spaces are met as described in this document. For projects where an electrical engineer is involved, the Designer shall coordinate directly with the engineer, and verify that the engineer’s design documentation meets these requirements. For projects without the involvement of an electrical engineer, the Designer shall alert CWU where additional power infrastructure is needed to meet the requirements.

B. Electrical plans for new or altered electrical installations in some CWU

facilities must be reviewed by the Washington State Department of Labor and Industries and approved prior to construction, per WAC 296-46B-010.

• Paragraph 14 (a) of this WAC requirement defines the applicable facility

types as follows: “Educational facility refers to a building or portion of a building used primarily for educational purposes by six or more persons at one time for twelve hours per week or four hours in any one day. Educational occupancy includes: Schools (preschool through grade twelve), colleges, academies, universities, and trade schools.”

4.7.6.1 Technical Power Panels

A. The technical power circuits in each telecommunications room shall originate from a technical power panel, dedicated to serving the TR. In the absence of other influencing circumstances, the panel shall be sized for 100 amp service. The technical power panel shall not be used to supply power to sources of electromagnetic interference such as large electric motors, arc welding, or industrial equipment. The power panel shall be located in the TR or in close proximity to the TR. The technical power panel shall be labeled “Telecommunications Equipment Only.”

• If standby generator power is available to the facility, the TR technical

power panel shall be served by the generator. • Some circumstances might not justify a dedicated technical power panel.

In these cases, an available general-purpose electrical panel may be used. The Designer shall seek direction from CWU regarding a decision to not


POWER REQUIREMENTS

78

design a dedicated technical power panel.

B. Where telecommunications cabinets are used in lieu of a TR, an available general-purpose power panel may be used to support the telecommunications cabinet power outlet. However, the power panel shall not be used to supply power to sources of electromagnetic interference such as large electric motors, arc welding, or industrial equipment. The power panel shall be located in close proximity to the cabinet.

4.7.6.2 Technical Power Outlets

A. Duplex power outlets (120VAC / 20 Ampere) shall be provided for exclusive use by telecommunications related electronic equipment and shall be supplied by circuits that are dedicated to telecommunications uses only.

• Outlets shall be colored orange, labeled as “Technical Power” and shall

show the panel and circuit numbers. • Technical power outlets shall be equipped for “straight-blade plugs”

(NEMA 5-20R), rather than twist-lock style receptacles. • Each outlet shall be equipped with a dedicated #12 AWG insulated solid

copper equipment-grounding conductor. • At least three circuits shall be provided for technical power to each

telecommunications room and up to three outlets may be combined on any one circuit.

• Alternate the outlets amongst the different circuits so that adjacent outlets are not on the same circuit.

B. The Designer shall obtain connection/load requirements from CWU for each

piece of equipment, and tabulate the information for review and confirmation by CWU. This equipment may include network electronics, UPS equipment, computers/servers, phone system equipment, voice mail systems, video equipment and service provider equipment.

C. The Designer shall specifically investigate the potential need for voltage or

ampere requirements other than the typical 120VAC / 20 Ampere power outlet. Some UPS and network switch equipment requires specialized plugs or electrical service. The Designer shall inquire with CWU ITS to determine whether any dedicated or specialized circuit requirements exist.

4.7.6.2.1 For New Construction and Full Remodel

A. Each telecommunications cabinet shall be equipped with a minimum of one duplex technical power outlet installed inside, near the bottom of the cabinet.

B. Faceplates for power receptacles and light switches in the TR shall be

mounted at the surface of the plywood backboard (as opposed to being recessed into a cutout in the plywood backboard).

4.7.6.2.1.1 TELECOMMUNICATIONS ROOMS WITH ONE OR TWO FLOOR-STANDING RACKS

A. One duplex technical power outlet per floor-standing rack shall be provided to serve each rack. The outlet(s) shall be mounted on the side wall nearest the racks approximately 18 inches behind the rack. Technical power outlets shall


POWER REQUIREMENTS

79

be mounted at the standard mounting height above the finished floor. B. The rack nearest the wall is expected to host a rack-mounted UPS at the base

of the rack as well as a 72” vertical power strip attached to the vertical cable management on the non-wall side of the rack. The UPS will plug into the duplex power outlet, and the power strip will plug into the UPS.

C. Electronic equipment in the second rack is typically powered by the vertical

power strip. However, if necessary another UPS can be installed in the base of the second rack and the power cord can be routed beneath the first UPS to the second rack-dedicated technical power outlet.

D. Typically, the contractor is required to furnish and install the vertical power

strip, and CWU furnishes and installs the UPS equipment. E. For racks where CWU intends to install equipment with dual-redundant power

supplies, two duplex technical power outlets with separate circuits shall be provided for those racks. The Designer shall inquire with CWU whether equipment with dual power supplies will be used.

4.7.6.2.1.2 TELECOMMUNICATIONS ROOMS WITH MORE THAN TWO FLOOR-STANDING RACKS

A. The first two racks are served as described above. B. A dedicated duplex technical power outlet (pedestal style) shall be floor-

mounted near the vertical cable management of each additional rack. C. Conduit for each pedestal outlet shall be concealed in the floor where

possible. Otherwise, the conduit shall be routed exposed from the wall to the pedestal, above the base-plates of the first and second racks. The bottom rack spaces (reserved for UPS equipment) shall not be obstructed by the power conduit.

4.7.6.2.1.3 OTHER TECHNICAL POWER OUTLETS

In addition to the outlets intended to serve the racks, a minimum of one duplex technical power outlet shall be provided per wall (centered on the wall) except for the wall adjacent to the racks. For walls more than 10’ in length a minimum of 2 outlets shall be provided, and at intervals of no more than 6 feet between outlets.

4.7.6.2.2 For Light Remodel Projects

A. The design shall include technical power outlets according to the “new construction” requirements, wherever possible. However, for some projects it may not be realistic or practical to meet those requirements. The following two paragraphs describe an alternative arrangement of technical power outlets that may be approved on a project-by-project basis via the ADR process:

• If it is not practical to install a new power outlet at the base of each

equipment rack, it may be acceptable to serve the rack’s power needs from a wall-mounted outlet.

• If power outlets are not installed at the base of each rack, the number of

DESIGN CRITERIA EQUIPMENT ROOMS

GROUNDING, BONDING, AND ELECTRICAL PROTECTION

80

wall-mounted technical power outlets shall be increased to an interval of one outlet every 4 feet. Power outlets in this arrangement shall be located such that they are conveniently aligned with the equipment racks to avoid inadvertent disconnection of the power cords.

B. In light remodel projects where telecommunications backboards are applied

to existing walls with existing power outlets and light switches, the design shall require backboards to be provided with cutouts permitting access to the existing electrical devices.

4.7.6.3 Additional Convenience Power Outlets

A. In addition to the technical power outlets described above, the design shall require the Contractor to provide other duplex convenience outlets (120VAC, 15 Ampere) that would be available for use with power tools and testing equipment. Each outlet shall be labeled with its panel identification and circuit number.

B. Where telecommunications cabinets are used in lieu of a TR, there shall be at

least one general-purpose convenience power outlet (120VAC, 15 Ampere) located within six feet of each telecommunications cabinet. This outlet shall be colored consistently with other convenience outlets in the building. The general-purpose outlet shall not be used to power telecommunications equipment associated with the cabinet.

4.7.7 GROUNDING, BONDING, AND ELECTRICAL PROTECTION

All equipment racks, metallic conduits and exposed non-current carrying metal parts of telecommunications and information technology equipment in the TR shall be bonded to the TMGB. Refer to the Grounding, Bonding and Electrical Protection section of the BICSI TDMM and this document for more information regarding the design of grounding, bonding and electrical protection systems.

4.8 EQUIPMENT ROOMS

Please refer to the Equipment Rooms section of the BICSI TDMM for general information regarding the design of equipment rooms. The following requirements take precedence over the BICSI TDMM guidelines for telecommunications infrastructure at CWU facilities: A. The main telecommunications Equipment Room (ER) at CWU’s Ellensburg

campus is called the “Computer Center” and is also known by the nickname “Wildcat”. This facility is dedicated to telecommunications functions and houses the main telecommunications cabling cross connection facilities, the main network switch and server equipment, and the telephone system PBX and voice mail equipment. At remote campuses where CWU has facilities, similar main telecommunications equipment rooms also exist.

• Design of a new equipment room serving an entire campus (for example

replacing the Computer Center, or at a remote campus) is considered to be a relatively rare project and is not anticipated in the foreseeable future.


EQUIPMENT ROOM LOCATION

81

This document may not completely describe the design guidelines for such a significant project. If such a project is undertaken, close consultation with CWU ITS staff is required on all aspects of the project.

• Access to the Computer Center is strictly controlled for security purposes.

For project work inside the building, advance written notice shall be given to CWU ITS and the activities shall be scheduled to coordinate with operations in the building.

B. Typically, CWU incorporates the building-level equipment room functions into

the main telecommunications room for the building, and does not usually create a separate equipment room space. As a result, the size of the main telecommunications room in a building shall be upsized to support the equipment room functions. On a project-by-project basis, the Designer shall seek the direction of the CWU ITS Infrastructure Specialist regarding the sizing necessary to accommodate the equipment intended to be housed in the space.

C. The requirements in the “Telecommunications Rooms and Enclosures” section

(above) shall be followed for designing equipment rooms in CWU facilities. D. The remainder of the “Equipment Room” section of this document (below)

describes the additional requirements that shall be considered for applicability to the equipment room functions within a building’s main telecommunications room. The Designer shall seek direction from the CWU ITS Infrastructure Specialist regarding whether specific requirements shall apply on a project-by-project basis.

4.8.1 EQUIPMENT ROOM LOCATION

A. CWU hosts all telecommunications equipment, including voice, data, and video, in a single equipment room. A separate room for each of these functions is undesirable.

B. The ER shall be located within the main telecommunications room and

entrance facility creating a single telecommunications space serving all three functions.

• If a co-located ER is not practical/possible, the ER shall be located within

close proximity to the telecommunications entrance facility and the main telecommunications room.

C. In new construction, the ER shall be provisioned to host the major voice,

data, and video equipment required to support the building or campus, and the other computer based and networked low voltage systems. In a full remodel or light remodeling project with existing facilities, every reasonable effort shall be made to co-locate these systems in a common equipment room.

D. The ER shall not be located in any of the locations listed below:

1. Areas subject to water or steam infiltration, particularly basements. A


EQUIPMENT ROOM SIZING

82

floor drain (with a trap primer) is required if there is any risk of water entering the ER.

2. Areas exposed to excessive heat or direct sunlight. 3. Areas exposed to corrosive atmospheric or environmental conditions. 4. Near or adjacent to potential sources of electromagnetic interference

(EMI) or radio frequency interference (RFI) such as large electric motors, power transformers, arc welding equipment, or high power radio transmitting antennas.

5. In a shared space with electrical equipment other than equipment serving the telecommunications system.

4.8.2 EQUIPMENT ROOM SIZING

A. The first step in determining the size required for an ER, is to identify the systems that will be installed into the ER. In this process, first identify the size of the area that will be served from the ER. Next, identify the quantity, size and variety of systems to be installed to support the area, and the space required for each of the systems.

B. The Designer shall consult with the CWU ITS Infrastructure Specialist to

determine any sizing requirements for the ER on a project-by-project basis.

C. A model that CWU has used to create a preliminary forecast of the space needed for an ER in a building is to design 0.75 ft2 of ER floor space for every 100-ft2 work area to be served in the building.

D. Once the size and quantity of systems are identified, they shall be laid out in

a functionally efficient arrangement. Some equipment, such as WAN equipment, LAN servers, tape backup equipment, hubs, switches, and patch panels will require regular access, and shall be arranged in an easily accessible manner.

E. When laying out the arrangement of the ER, the following requirements and

issues shall be addressed: 1. Equipment shall be grouped together with like equipment (i.e., voice, data

for both LAN and WAN, video.) 2. Designate wall space and equipment rack space for each specific use.

Allocate specific backboard space for the service providers’ demarcation areas and any associated equipment. The wall space allocated to the service providers shall be located adjacent to each other on a common wall and on a single aisle of equipment racks to concentrate the activities of service technicians in areas away from CWU-owned systems in other areas of the equipment room.

3. Allocate separate wall and equipment rack space for terminating and cross connecting campus distribution cables (both copper and fiber optic). These areas shall be located adjacent to the equipment providing the services, such as the PBX, voice mail system, and data network electronics.

4. Equipment racks and rack-mounted equipment shall have a minimum of three feet of unrestricted clearance in front and back for technician access. In smaller installations, wall mounted swing-out equipment racks


ARCHITECTURAL PROVISIONING

83

can be used to save space, but shall have a three-foot clearance to the front of the rack. Note that some LAN equipment may be large, or may require clearance at both the front and back, and wall mounted swing-out racks may not be appropriate.

F. Once an acceptable equipment layout is developed, the size of the equipment

room can be calculated. The design shall include a minimum of 25% vacant space for future growth.

G. Equipment rooms shall be sized with at least 150 ft2 of usable floor space. H. The CWU ITS Infrastructure Specialist shall approve the final space

requirements and design layout for the equipment and racks.

4.8.3 ARCHITECTURAL PROVISIONING

Equipment room floors shall be structurally designed to accommodate the heaviest equipment intended for the space or BICSI’s 250 lb/ft2 guideline, whichever is greater. • In large equipment rooms, a raised access floor is required. The raised floor shall

have a minimum of 8 inches clearance to the base floor, and shall not be used as an air plenum. If raised access flooring used, the ceiling height must be raised to maintain a minimum clearance of 8 feet. The Designer shall inquire with CWU to determine whether an access floor is desired.

4.8.4 ENVIRONMENTAL PROVISIONING

Where fire suppression sprinklers are used, sprinklers shall be equipped with wire cages under the sprinkler heads to prevent accidental discharge. Drainage troughs shall be placed under the sprinkler pipes to prevent leakage onto the equipment within the room.

4.8.5 FLOOR-STANDING EQUIPMENT RACKS

Some IT equipment requires an equipment rack with both front and rear mounting rails. The Designer shall discuss with CWU the network electronics that will be hosted in each rack in each ER and shall show this equipment on the rack elevation details in the plan drawings. The Designer shall also discuss with CWU the potential for future additional racks, and identify spaces for the future racks on the plan drawings

4.8.6 TELECOMMUNICATIONS CABINETS

A. Other styles of equipment racks and cabinets might be used in the ER, some of which may be proprietary to a particular system or service provider. The Designer shall plan the ER layout to make allowances for proprietary cabinets and racks, and allow expansion room for future equipment.

B. Floor-standing cabinets shall have front and rear hinged doors to permit

access to both the front and rear of the equipment. Telecommunications


POWER REQUIREMENTS

84

cabinets shall be constructed of heavy gauge steel. The side panels of the cabinet shall be removable for maintenance accessibility.

C. Each cabinet shall be vented and where appropriate shall be equipped with

cooling fans.

4.8.7 POWER REQUIREMENTS

4.8.7.1 Technical Power Panels

A. A separate supply circuit serving the room shall be provided and terminated in its own electrical panel located in the ER. This power panel shall be designated as “ER Technical Power.” The ER technical power panel shall be used exclusively for supplying power to electronics equipment in the equipment room. Sizing of electrical power supply is dependent upon the equipment types and equipment load, and shall be calculated on a case-by-case basis, including sufficient spare capacity for future growth.

B. The technical power circuits in each ER shall originate from a technical power

panel, dedicated to serving the ER. The technical power panel shall not be used to supply power to sources of electromagnetic interference such as large electric motors, arc welding, or industrial equipment.

C. If standby generator power is available to the facility, the ER technical power

panel shall be linked to the standby generator power supply.

D. Power for critical network components such as servers, routers, switches, and telephone systems shall always be provided through at least one uninterruptible power supply (UPS).

E. Generally speaking, CWU does not use centralized UPS equipment. However,

if CWU wishes to use a centralized UPS, the following requirements shall be met:

• Some centralized UPS vent noxious battery gasses. The UPS shall

therefore be housed in a room that is equipped to properly vent the gasses. Centralized UPSs shall not be located within the ER itself. Rooms housing centralized UPS systems shall have the same environmental provisioning features as the ER.

• Some battery manufacturers claim that valve-regulated lead acid batteries

do not emit gasses and therefore might not require mechanical systems for venting battery gasses. The Designer shall evaluate such claims for applicability on each project.

• The UPS’ battery bank shall be sized to provide a minimum of two hours

of run time for the supported low voltage systems hardware. The Designer shall request direction from the CWU ITS Infrastructure Specialist regarding project specific needs for increased the run time.



85

• Upon installation, a qualified electrician shall test new centralized UPS units for correct output voltage prior to connecting electronic equipment.

• Centralized UPS equipment shall be provided with a network interface card

so that the UPS can communicate via the network with servers and other equipment to orchestrate a coordinated safe-shutdown of the equipment in the event of an extended power outage. The telecommunications cabling design shall require a telecommunications outlet located in the centralized UPS room near each UPS to support the UPS’ network connection.

4.8.7.2 Technical Power Outlets

A. Generally, the power outlet requirements that are applicable to telecommunications rooms are also applicable to equipment rooms. Technical power outlets shall be provided as described in the “Telecommunications Rooms and Enclosures” section (above).

B. The Designer shall obtain connection/load requirements from CWU for each

piece of equipment, and tabulate the information for review and confirmation by CWU. This equipment may include network electronics, UPS equipment, computers/servers, phone system equipment, voice mail systems, video equipment and service provider equipment.

C. Some telephone PBX equipment, UPS equipment and network switch

equipment require specialized plugs or electrical service. The Designer shall specifically investigate the potential need for voltage or ampere requirements other than the typical 120VAC / 20 Ampere power outlet, and shall coordinate with the design team to design the electrical power infrastructure to serve the needs of the equipment.

4.8.7.2.1 For Remodel Projects

If an equipment room is truly required in a remodel project, budget limitations and other constraints should be resolved through actions that do not deviate from meeting the requirements of this document. In particular, the electrical power requirements of equipment in an equipment room shall not be discounted or taken lightly.

4.8.7.3 Convenience Power Outlets

Convenience power outlets shall be provided as described (above) in the “Telecommunications Rooms and Enclosures” section.

4.8.8 GROUNDING, BONDING, AND ELECTRICAL PROTECTION

All equipment racks, metallic conduits and exposed non-current carrying metal parts of telecommunications and information technology equipment in the ER shall be bonded to the TMGB. Please refer to the Grounding, Bonding and Electrical Protection section of the BICSI TDMM and this document for more information regarding the design of grounding, bonding and electrical protection systems.

DESIGN CRITERIA TELECOMMUNICATIONS ENTRANCE FACILITIES & TERMINATION


86

• The ER have a dedicated/isolated ground wire routed inside a metallic conduit directly from the main electrical service-grounding electrode for PBX equipment. This ground wire is in addition to and separate from the telecommunications grounding system.

4.9 TELECOMMUNICATIONS ENTRANCE FACILITIES & TERMINATION

Please refer to the Telecommunications Entrance Facilities & Termination section of the BICSI TDMM for general information regarding the design of telecommunications entrance facilities. The following requirements take precedence over the BICSI TDMM guidelines for telecommunications infrastructure at CWU facilities: A. The entrance facility (EF) shall be located within the building’s equipment

room or main telecommunications room.

• In light remodel projects, it is possible that the EF may already exist and that it is expected to be reused. This may be acceptable if the size is appropriate, if there is sufficient environmental provisioning, and if adequate separation from sources of EMI is maintained. It may be desirable to extend the incoming entrance conduits (using rigid galvanized steel conduit) from a non-telecommunications space to a dedicated telecommunications room.

B. OSP conduits shall be extended into the entrance facility to the point that no

more than fifty feet of outdoor-rated cabling is exposed, including slack loops and termination. Fire-rated tape wrap is not acceptable. For more information, see the Inter-Building (Campus) Backbone Pathways section and the Inter-Building (Campus) Backbone Cabling section, above.

C. Ducts shall enter the entrance facility parallel to the backboard to be used -

perpendicular entry may cause cables to sharply bend beyond their minimum allowable bend radius.

4.10 GROUNDING BONDING AND ELECTRICAL PROTECTION

Please refer to the Grounding, Bonding and Electrical Protection section of the BICSI TDMM for general information regarding the design of grounding, bonding and electrical protection systems. See also the Grounding, Bonding and Electrical Protection section of the BICSI CO-OSP for more information. The following requirements take precedence over the BICSI TDMM guidelines for telecommunications infrastructure at CWU facilities: A. A Telecommunications Main Grounding Busbar (TMGB) shall be installed at an

accessible and convenient location in each Entrance Facility. A Telecommunications Grounding Busbar (TGB) shall be installed at an accessible and convenient location in each Equipment Room and Telecommunications Room. TMGBs and TGBs shall be sized to accommodate 30% future growth.

B. A green-insulated copper cable (sized between a minimum of #6 AWG and a

DESIGN CRITERIA FIRESTOPPING


87

maximum of 3/0 AWG) shall be provided between each TGB and TMGB and from the TMGB to the building main electrical service ground electrode. The Designer shall evaluate the grounding cable size that will be appropriate for each application.

C. Generally, grounding and bonding infrastructure shall be installed by the

contractor. However, for light remodel construction, the Designer shall coordinate with CWU electricians who may install and connect the ground wire between the existing building ground and the Contractor-installed grounding busbar in a telecommunications room.

D. While CWU does not permit telecommunications design solutions to include

splices to fiber optic cabling and also prefers that copper backbone cabling not be spliced, occasionally it becomes necessary to splice cables. Where any splices are made to backbone cables, the metallic shields of those cables shall be bonded together to maintain shield continuity and shall also be bonded to ground at splice locations.

4.11 FIRESTOPPING

Please refer to the Firestopping section of the BICSI TDMM for general information regarding the design of firestopping for telecommunications infrastructure. The following requirements take precedence over the BICSI TDMM guidelines for telecommunications infrastructure at CWU facilities: A. Penetrations through fire-rated walls and floors shall be firestopped in

accordance with the requirements of the manufacturer of the firestopping materials and satisfy local code officials.

B. The Designer shall avoid design solutions calling for penetration of fire-rated

walls and floors when other reasonable cable-routing options exist.

4.12 FIELD TESTING

Please refer to the Field Testing section of the BICSI TDMM for general information regarding the field-testing of telecommunications cabling. The following requirements take precedence over the BICSI TDMM guidelines for field-testing at CWU facilities: A. The Designer shall review the cable test results submitted by the Contractor.

The test results shall be the actual native machine test results downloaded from the test equipment. In particular, the Designer shall check for the following items on the cable test reports:

• Indications that the cabling has successfully passed the testing • Indications that the cabling meets distance limitation requirements • Indications that the wire-map of the cable is correct • Indications that the cable test equipment was properly configured. For

copper cabling, the test equipment’s configuration parameter for Nominal Velocity of Propagation (NVP) shall match the value stated by the cabling

DESIGN CRITERIA SPECIAL DESIGN CONSIDERATIONS

88

manufacturer for the type of cable installed.

B. The cabling performance characteristics shall meet or exceed the performance guaranteed by the manufacturer, which may exceed standard industry requirements. In other words, even though a particular cable might pass its tests, the cable might still be rejected (requiring re-termination or replacement) if it does not meet the higher standard of performance that the manufacturer may list for its products.

C. The final test results shall have been verified by the Designer to be acceptable

before submission to CWU. Test results shall be submitted to CWU in both electronic and paper forms.

4.13 SPECIAL DESIGN CONSIDERATIONS

Please refer to the Special Design Considerations section of the BICSI TDMM for information regarding the design of telecommunications infrastructure in accordance with the Americans with Disabilities Act (ADA) requirements at CWU facilities. The Designer shall request guidance from CWU regarding the requirements for any special design considerations, including: • Coin-operated and other public-use telephones within CWU facilities. • Spaces within CWU facilities intended to include Americans with Disabilities Act

(ADA) features.

4.14 TELECOMMUNICATIONS ADMINISTRATION

Please refer to the Telecommunications Administration section of the BICSI TDMM for general information regarding the documentation and labeling of telecommunications infrastructure. The following requirements take precedence over the BICSI TDMM guidelines for telecommunications infrastructure at CWU facilities:

4.14.1 IDENTIFICATION STRATEGY

A. The “identifier” is the unique name or description assigned to a telecommunications infrastructure component. The Designer shall assign identifiers to the telecommunications infrastructure components listed below and clearly show the identifier assignments on the Construction Documents.

B. While it is the Contractor’s responsibility to provide marked-up drawings to

the Designer indicating any construction-related changes to the identifiers, the Designer shall verify that the identifiers are clearly and accurately shown on the record drawings.

C. Telecommunications components shall not be labeled with an application-

specific identifier. Ports shall not be labeled with the name or function of the device that is served by the port (server names, computer types. Also, the use of “V-#” and “D-#” are inconsistent with the industry standard-based

DESIGN CRITERIA TELECOMMUNICATIONS ADMINISTRATION


89

philosophy of designing cabling systems that are independent of the application, and are therefore not permitted.

D. The TCGS contains a comprehensive listing of the identification strategy

requirements, including some items that are not addressed below. The items listed below shall be shown on the Construction Documents, whereas the TCGS includes some identification and labeling requirements that do not typically appear on the Construction Documents.

4.14.1.1 New Telecommunications Distribution Systems

The Designer shall assign the identifiers to the telecommunications components based on the following identification strategy: A. Maintenance holes and handholes shall be named by CWU. The Designer

shall not assign names or numbers to maintenance holes or handholes but instead shall contact CWU’s Facility Management Department and obtain authorized identifiers from the Campus Utility Map system. The authorized identifiers are automatically generated according to CWU’s two-tiered alphanumeric grid system. The format for these identifiers shall be “A##B&&” where “A” represents the letter of the alphabet associated with the row in the “major-grid” (vertical axis) and “##” represents a two-digit number (leading “0” if necessary) associated with the column in the “major-grid” (horizontal axis) wherein the maintenance hole or handhole is located. The “B” represents the row (vertical axis) of a “minor-grid” within the major grid and “&&” represents a two-digit number (leading “0” if necessary) associated with the column in the “minor-grid” (horizontal axis) wherein the maintenance hole or handhole is located. o For example, a maintenance hole or handhole located in the major-grid

square identified by the row “G” and the column “11” and within the minor-grid square identified by the row “O” (the letter “O”) and the column “2” shall be identified as “G11O02” (always use two digits for the column number). No distinction is made between maintenance holes and handholes in the identifier scheme.

B. Campus Backbone cables shall be named by CWU. The Designer shall not

assign names or numbers to maintenance holes or handholes but instead shall contact CWU’s Facility Management Department and obtain authorized identifiers from the Campus Utility Map system. The authorized identifiers are assigned in coordination with other existing cables. Campus backbone cables shall have identifiers in the form of “M##” where “M” is either “F” (for fiber backbone media) or “C” (for copper backbone media) and “##” is a unique, two-digit sequential cable number. o For example: The first three outside plant fiber backbone cables designed

on a project shall be identified as “F01”, “F02” and “F03”. The eleventh, twelfth and thirteenth outside plant copper backbone cables designed on a project shall be identified as “C11”, “C12” and “C13”.

C. Telecommunications rooms (and Equipment Rooms) shall have identifiers in

the form of “FX”, where “F” is the floor number on which the

DESIGN CRITERIA TELECOMMUNICATIONS ADMINISTRATION


90

telecommunications rooms resides and “X” represents a sequentially assigned letter to distinguish between multiple rooms on the floor. o For example: A building with two telecommunications rooms on the third

floor would have rooms labeled “3A” and “3B”. D. Racks in telecommunications rooms shall have identifiers of the form “R#”

where “R” stands for “Rack” and “#” is the sequential rack number within a given TR. o For example: The first rack in a given telecommunications room would

have the label “R1”, the second “R2” and so on. E. Patch Panels shall have identifiers sequentially numbered in the form of “PP#”

where “PP” stands for “Patch Panel” and “#” is the sequential patch panel number terminated within a given telecommunications room, regardless of media type (horizontal copper or horizontal fiber). o For example: The first patch panel (terminating horizontal fiber optic

cabling in duplex SC ports) would be labeled “PP1”. o For example: The second patch panel (terminating horizontal copper

cabling) would have the label “PP2”. F. Termination Blocks for Backbone Distribution shall have a single label affixed

above the entire termination block wall field which reads “Backbone”. Also, label each termination block column within the termination block wall field in the form “TR”, where “TR” is the telecommunications room where the backbone cable originates (see the Telecommunications Rooms section above). Use a new column for each telecommunications room. Do not intermix cables from multiple telecommunications rooms in a single termination block column. o For example: If a termination block column on the fourth floor terminates

backbone cabling from the first floor telecommunications room, then the column on the fourth floor would have the label “1A” and the termination block column on the first floor would have the label “4A.”

G. Termination Strips on Termination Blocks for Backbone Distribution shall have

a label of the form “###” where “###” denotes the sequential cable number terminated. o For example: A termination strip used to terminate a 12-pair backbone

cable would be labeled “001, 002, 003, 004, 005, 006, 007, 008, 009, 010, 011, 012” corresponding to the backbone cable pair numbers.

H. Ports on Patch Panels for Horizontal Cabling are typically pre-labeled by the

manufacturer with sequential numbers (i.e. 1 to 48). For ports which are not pre-labeled, label each port in the form “##” where “##” is the sequential port number within the panel. The ports in each patch panel shall start at number “01”. o For example: The ports on a patch panel terminating horizontal fiber

optic cabling in duplex SC ports would be labeled starting with “01” for the first duplex port (one label per pair of fiber strands) and continue sequentially through the remainder of the duplex ports.

DESIGN CRITERIA DESIGN, CONSTRUCTION AND PROJECT MANAGEMENT

I. Termination Blocks for Horizontal Cabling shall have a single label affixed above the entire termination block column indicating the floor number on which the outlets are located, whose cable terminates on that column. o For example: A termination block column terminating workstation cables

from the second floor would have the label “2nd Floor.” J. Termination Strips on Termination Blocks for Horizontal Cabling shall have a

label of the form “###” where “###” denotes the sequential cable number terminated (see Cables, above). o For example: Two termination strips are used to terminate 6 single gang

two jack outlets with sequential cable numbers “001” to “012.” The top termination strip pairs would be labeled “001, 003, 005, 007, 009, 011” and the bottom termination strip would be labeled “002, 004, 006, 008, 009, 012.”

K. Work Area Connectors (Ports) shall have identifiers in the form of “FTR-###”

where “F” is the floor of the telecommunications outlet where the horizontal cable terminates, “TR” is the telecommunications room where the cable terminates (see the Telecommunications Rooms section above), and “###” is the sequential cable number for that telecommunications room. o For example: If an outlet on the third floor has a faceplate with two

copper cables (sequentially numbered 5 and 6) terminated in the second telecommunications room on the fourth floor, then the connectors would have the labels “34B-005” and “34B-006” respectively.

4.14.1.2 Moves, Adds and Changes (MAC)

The only exception to the above identification scheme is for small projects relating to moves or changes to existing cabling, or the addition of new outlets terminated among other existing cables in existing TRs. In such cases, the cable identification scheme for the new cables shall be consistent with the existing identification scheme.

6.8 GLOSSARY

ANALOG

Analog comes from the root word “analogous,” which means “similar to.” In telecommunications, analog is a way of sending signals—voice, data, or video—in which the transmitted signal is analogous to the original signal. In other words, if you spoke into a microphone and saw your voice on an oscilloscope took the same voice as was transmitted on the phone line and viewed that signal on an oscilloscope, the two signals would look the same. See Digital.

AWG (AMERICAN WIRE GAUGE)

The standard measuring gauge of the diameter of copper wires in telecommunications and electrical cables.

BACKBOARD

A plywood sheet mounted to the wall where telecommunications distribution equipment is installed. The backboard must be three-quarter (¾)-inch thick A-C grade fire retardant plywood, mounted with the “A” side exposed. The backboard must be coated with two coats of light colored, non-conductive fire retardant paint.

BACKBONE CABLING

Backbone cable is defined as a major service cable that is used to interconnect various buildings on a campus, connect equipment rooms to telecommunications rooms within a building, or connect one telecommunications room to another within the same building. Backbone cables are typically large capacity (high pair-count) copper cables, or fiber optic cables.

BEND RADIUS

The maximum radius that a cable can be bent to avoid physical or electrical damage or cause adverse transmission performance.

BONDING

The permanent joining of metallic parts to form an electrically conductive path that will assure electrical continuity and the capacity to conduct safely to ground any current likely to be imposed.

BUS

An electrical connection which allows two or more wires to be bonded together.

BUSBAR

A copper bar, drilled and tapped, to allow the bonding together of wires or cables.

CABLE PAIR

Each telecommunications circuit is made up of two copper wires, or a pair of wires. Traditional analog telephone service uses one-pair of wires. Some modern digital telephone systems, and most computer networks operate over two or four pairs of wires. The ANSI/TIA/EIA-568-A standard requires a four-pair cable to each work-area modular jack.

CABLE PLANT

A term which refers to the physical connection media such as optical fiber cable or copper cable. See Telecommunications Infrastructure.

INDEX

111

CABLE PULL TENSION

Stated by the manufacturer as the maximum limit at which the cable’s performance characteristics are altered, experiencing electrical or mechanical degradation. Also known as maximum recommended installation load (MRIL).

CABLE TENSILE STRENGTH

Is the limit point where the cable is pulled apart.

CHANGE ORDER (CO)

Change Orders document the modifications to an existing contract. The change order procedure can be initiated by the Owner, Contractor, or the A/E. The A.E will generally start the process using the Change Order/Change Order Proposal form.

CAMPUS

The buildings and grounds of a complex or facility.

CATV (COMMUNITY ANTENNA TELEVISION)

CATV is commonly referred to as “cable TV.” In the traditional sense, CATV is a master antenna that receives television signals, and distributes the signal over cables to a limited geographical area, such as a campus, or neighborhood (community). Some CWU facilities (such as residence halls) receive cable TV service from a local service provider for a subscription fee. Other CWU facilities receive cable TV service via the campus video distribution infrastructure.

CCTV (CLOSED CIRCUIT TELEVISION)

CCTV is a system where one or more cameras send a television signals to television monitors at another location in the same building or campus.

CROSS-CONNECT (XC)

A cross-connect, or cross-connection, is where individual cable pairs from two different cables are connected together with jumper wires. An XC is intended to be easily reconfigured, as opposed to a cable splice which is permanent.

DATA SERVICES

Data service generally refers to the computer network. For future planning purposes, data shall be considered to be any information that is transferred in digital form. Advances in technology are blending together traditional voice, data, and video services. Eventually, a single telecommunications system may process all forms of telecommunications (voice, data, and video) over a common infrastructure.

DEMARC

The point of demarcation between the service provider and the customer. The demarc is actually a cable termination block with an orange cover where the service provider’s cable terminates. The services are then cross-connected to the customer’s cable for distribution throughout the facility. See Telecommunications Service Entrance Facility.

DIGITAL

In telecommunications or computing, digital is the use of a binary code to represent information. In binary code, the information is represented by a series of “on” or “off” states (a signal, or an absence of a signal). Analog signals—like a voice—are encoded digitally by sampling the voice analog signal many times a second and assigning a number to each sample. During transmission, the signals will lose strength and progressively pick up noise or distortion. In analog transmission, the signal (along with any noise that is picked up) is simply amplified to maintain the proper signal strength at the distant end. In digital transmission, the signal is regenerated, cleaning off any noise, and restoring the signal to its original form. Then the signal is amplified, and sent to the destination. At the destination,

INDEX

112

the digital signal is again regenerated, and restored to its original form for processing. See Analog.

ELECTRO MAGNETIC INTERFERENCE (EMI)

Electro Magnetic Interference is a signal distortion directly related to a foreign signal being imposed through coupling onto a transmission path to which the foreign signal is not physically connected.

ENTRANCE FACILITY (EF)

See Telecommunications Service Entrance Facility (EF).

FACILITY CONTROL AND MONITORING

It is becoming increasingly common for heating, ventilation, air conditioning, power distribution, and water distribution systems to be computer controlled. These computer-controlled systems can be networked on the same LAN, or the same telecommunications infrastructure, as the traditional data services.

FIRE AND LIFE SAFETY

As with Facility Control and Monitoring systems, Fire and Life Safety systems such as smoke detectors, sprinkler systems, and fire alarms are increasingly becoming computer controlled and networked. These systems can also communicate over the common telecommunications infrastructure. Local codes may have certain restrictions on the manner in which Fire and Life Safety systems are networked, and shall be consulted prior to system design.

GROUND

A conducting connection, whether intentional or accidental, between an electrical circuit or equipment and the earth, or to some conducting body that serves in place of the earth.


Proper grounding and bonding serves three very important purposes. First, from a life safety aspect, the ground connection insures that voltages from a malfunctioning system are routed directly to ground to prevent an electrocution hazard to people who may come in physical contact with the system. Secondly, from a telecommunications standpoint, grounding and bonding of telecommunications equipment and systems is an important measure for controlling electromagnetic interference (EMI). Ungrounded systems can pick up energy that is radiated from another electrical source, such as a large electric motor, an arc welder, or a large copy machine. If this energy is absorbed into the telecommunications system, it can result in annoying interference on the signal, or at worst, corruption and loss of critical data. Thirdly, the telecommunications ground may be used as a reference voltage for electronics equipment. The telecommunications ground potential must be consistent to insure reliable system performance.

GROUNDING ELECTRODE

The metallic component that is placed in the earth to form the electrical connection with the earth. A grounding electrode is usually a metal rod at least eight (8)-feet long driven into the earth. Refer to NFPA 70, Article 250, Part H for acceptable electrical service grounding electrodes.

HANDHOLE

HORIZONTAL DISTRIBUTION CABLING (HDC)

Horizontal distribution cable is defined as the cable that routes from the telecommunications room to the work area. Generally, these cables are routed horizontally on the same floor of a building, as opposed to a backbone or “riser” cable that may route vertically in a building. Occasionally, a telecommunications room will also serve the floor above and/or below. In this case, the cables routing from the telecommunications room to a work-area on the floor above or below are still considered to be horizontal distribution cabling.
