Introducing the BSC3i and upgrades

2 Introducing the BSC3i and upgradesThe following sections describe the basic functionality of the BSC3i and its upgrades to Flexi BSC ("the network element"). The emphasis is on the hardware implementation of the system.

2.1 Overview of the network element in GSM/EDGE mobile networkThe base station controller (BSC3i) is a modern fault tolerant system for GSM800/GSM900/GSM1800/GSM1900 networks. The network element is based on modular software and hardware architecture. The distributed architecture of the network element is implemented with a high-capacity and redundant multiprocessor system - the DX 200 computing platform. The system enables the distribution of processing capacity to several computer units with dedicated tasks.

The DX 200 computing platform product family covers a wide application area in GSM/EDGE mobile networks and fixed telephone networks. The DX 200 computing platform product family contains products for digital mobile applications, such as base station controller (Flexi BSC product family), third-generation transcoder submultiplexer (TCSM3i), second-generation transcoder submultiplexer (TCSM2), DX MSC (MSC), MSC Server, DX HLR (HLR), and 2G/3G serving GPRS support node (SGSN), and also contains fixed network applications.

The main function of the network element is to control and manage the base station sub-system (BSS) and the radio channels. Based on long experience in cellular networks, the Flexi BSC product family is designed for efficient use of radio resources and is easy to operate and maintain. It is a stable, mature and highly reliable product. One major feature of network element is its field-proven multivendor functionality.

Together with the functionally distributed modular architecture of the DX 200 computing platform and the latest commercially available industry standard hardware components, the network element has high capacity and is simple and cost-efficient to expand.

Figure Flexi BSC in the GSM/EDGE (and 3G) mobile network shows the position of the BSC3i in the GSM/EDGE and 3G mobile network.

Figure 1 Flexi BSC in the GSM/EDGE (and 3G) mobile network

Modular structure of the network elementThe Flexi BSC product family is designed with a modular structure enabling a distributed processing architecture. This quality, combined with the wide range of both standard and optional features available, makes it readily adaptable to the needs of each individ-ual operator, as it allows for capacity dimensioning according to individual need. External costs resulting from surplus capacity are avoided, and the operator can choose a selection of features and services tailored to meet the demands of his customers. When additional capacity or new facilities are needed, the network element can easily be expanded by adding new hardware and/or software modules to the existing configu-ration.

The modular structure also allows for a compact design, which makes the network element easy to install and helps to maintain efficient power consumption.

2.2 DX 200 system architecture and network element block diagramLike the previous generations of DX 200 products, the Flexi BSC product family is designed with a modular software and hardware structure, which enables a distributed processing architecture. The distribution of processes is achieved by using a multi-pro-cessor system, in which the functions of the network element are divided among several functional entities, called functional units. Each functional unit has its own, separate hardware and software; most of them are equipped with a dedicated Pentium computer. These units are referred to as computer units, and they are interconnected by the

Introducing the BSC3i and upgrades

Ethernet-based Message Bus (EMB) introduced in S12 release, or, in releases prior to S12, by the Message Bus (MB), which again is organised as a functional unit of its own.

Each functional unit has a separate task group to handle. For example, the switch matrix has been organised as a separate unit, group switch (GSW2KB/GSW1KB/GSWB) and it is controlled by another unit, called the marker and cellular management unit (MCMU). The key operation and maintenance functions are performed by the operation and main-tenance unit (OMU), the external lines are interfaced by the Exchange Terminals (ETs), and the transcoder submultiplexer (TCSM) performs transcoding and submultiplexing functions. In releases prior to S12, the second-generation transcoder, the TCSM2, houses the TCSM units.

Figures Block diagram of the Flexi BSC (S14 release), Block diagram of the BSC3i (S13 and S12 releases) and Block diagram of the BSC3i (releases prior to S12) present the block diagram of the network element, which also shows the interfaces between the functional units and those connecting the system to the environment. The hardware of the functional units and the tasks each unit handles are described in more detail in Func-tional unit descriptions. More information is available in Product Description.

The S14 release introduces Ethernet Exchange Terminals (EETs) and equipment pro-tection for ETS2 and ETIP1-A plug-in units as new functionalities to BSC3i 1000/2000 and TCSM3i configurations.

In the following figure,

On S13 level, transcoding capacity can be increased by installing up to two extension cabinets (TCSA 1 and TCSA 2) in addition to old TCSA 0 cabinet to the TCSM3i part of TCSM3i for combined BSC/TCSM installation option. On S13 level, however, the BSC3i part must be BSC3i 1000, when extension cabinets TCSA 1 and TCSA 2 are to be equipped. S13-level equipment room layout is presented in Equipment room layout. For more information on TCSM3i for combined BSC/TCSM installation option, see Engi-neering for TCSM3i.

In S12 release, a new third-generation Transcoder Submultiplexer (TCSM3i High Capacity Transcoder Submultiplexer, the TCSM3i) housing the TCSM functional units is introduced. The TCSM is a functional unit of the BSC, but normally it is located in the MSC site in order to utilize to the fullest the transmission savings of the submultiplexing

2.3 DX 200 protection principlesThe reliability of the operations in the DX 200 network elements has been ensured by backing up all crucial parts of the system following various protection principles, as described in the sections below.

Protection of the functional unitsDifferent protection techniques are used for backing up different types of functional units. Each unit participating in the switching functions or recording of statistical data is backed up according to the 2N protection principle, that is, by duplication according to the hot-standby or spare-device method. On the other hand, each signalling unit is backed up according to the N+1 or N+1/L principle. The former term means that there is one spare unit available to take over the tasks of a faulty unit; in the latter case, the workload is shared between all devices, and if one malfunctions the other units are able to carry the full load.

Redundant functional units should be consistent, owing to protection principles. The pro-tection principle applied to each type of functional unit in the network element is given in Functional unit descriptions.

Protection of the power distribution, clock signal distribution and wired alarm col-lection systemsVirtually the entire power distribution chain from the rectifiers and power feed cables to individual pieces of equipment in the cabinets has been duplicated to minimise the risk of downtime due to power failures in the DX 200 equipment or cabling. On one hand,

Introducing the BSC3i and upgrades

the protection for the power supply from the rectifiers to the cabinets has been achieved by duplicating the power inputs in the cabinets, along with the input cables. On the other hand, the cabinet is equipped with a duplicated power distribution and fuse unit, which allows for feeding the voltages to units backing each other up through two separate dis-tribution lines.

Likewise, the DX 200 network elements have a duplicated clock distribution and alarm collection system. The basic clock signal can be fed to each BSC3i network element from up to six inputs, four from other network elements (in the same network or PSTN) and two from external sources.

Ensuring reliability at unit levelAt unit level, the following methods are used to ensure proper operation:

• error correcting RAM in critical parts • parity bit or ECC in read-write memories • parity checks in data transmission • reporting on certain error events in data transactions on the system bus • memory area protection (standard Intel processor capability) • automatic testing of connections • time-out supervision • validity checks for input data on different program levels • vital data (for example, call/event data) in protected memory • continuous supervision of the functioning of processes including restarts, when

required • continuous testing of operations (as background run) in all computer units

Backing up units without nominal protectionSome of the functional units of the network element are described as having no protec-tion at all. These include, for example, the ETs, that is, units which interface the network element to the environment. In fact, these units can also be backed up by ensuring that there is a sufficient number of circuits available in the same direction.

Another way to look at these units is to consider all units of a given type as a pool of resources, with several units available at a time to handle an assignment. A failure in one unit will only reduce the size of the pool but not interrupt the traffic; consequently, protection for the pool as a whole can be ensured simply by reserving some extra capacity for it when dimensioning the capacity of the network element.

SDH/SONET and IP/Ethernet protectionTwo optional protection methods are available for ETS2 SDH/SONET STM-1/OC-3 and ETIP1-A Gigabit Ethernet interfaces:

• transmission protection • equipment protection

Transmission protection

Transmission protection (see the following figure) is implemented as follows:

• ETS2, MSP 1+1 with two working and two protecting STM-1/OC-3 interfaces on one ETS2 plug-in unit

• ETIP1-A, one working and protecting GigE interface on one ETIP1-A plug-in unit

3 Mechanical construction of BSC3i and upgradesThe basic mechanical structure of the network element follows a standard hierarchy:

• cabinets • cartridges • plug-in units • internal cables

The system is easy to install, maintain, and operate. Particular attention has been paid to thermal and interference factors.

3.1 BSC3i cabinetsIC209-AThe equipment of the base cabinet (BSCC) and extension cabinet (BSCD) of the BSC3i network element is installed in a IC209-A cabinet variant.

Standards and recommendations

The IC209-A cabinet has a welded frame structure and it is designed following principles based on IEC, EN, ETSI, UL and Telcordia recommendations, with advanced features in terms of safety, protection against interference, stability, and durability.

The IC209-A meets the EN 60950 and UL 60950 safety requirements, along with the ETSI ETS 300019-1-3, Class 3.1E environmental requirements. The earthquake resis-tance of the cabinets is in accordance with Telcordia GR-63-CORE Zone 4, and the EMC emission and immunity features comply with the EN 300386 and (FCC) CFR 47, Part 15 standards, respectively.

The IC209-A is dimensioned according to ETS 300119-2 standard. The emphasis of the design is on easy transportability and suitability for installations in premises with normal room height. Because of the simple mechanical structure with relatively few compo-nents, the equipment cabinets are easy to assemble and disassemble when necessary.

BSCC and BSCD cabinet

The IC209-A cabinet from S12 release onwards consists of the following parts (see also figure BSCC and BSCD cabinets and their components in BSC3i 1000/2000):

• welded cabinet frame (IC209-A) • power supply connector groups (PSCG3-B) • power distribution fuse units (two PDFU-B units or four PDFU-A units) • upper air guide (can also be used for running cables from front to rear) • four fan trays for forced cooling (FTRB-A) • doors rear and front, left and right (DLH209-B and DRH209-B) • two side plates (SCP) • support rails for cartridge shelves • cartridge shelves • cable supporting shelves • wheels • adjustable feet for permanent installation

Figure 10 Side cable conduit (SCC)

The dimensions of the SCC are (H × W × D) 2000 mm × 600 mm × 75 mm.

3.2 CartridgesIn the design of the cartridges, particular attention has been paid to durability even under demanding conditions, along with dimensioning for optimal use of cabinet space. One cartridge usually contains the equipment of one functional unit. Two types of cartridges are used in the network element:

• 2 mm hard metric (HM) cartridges • Euroconnector cartridges

2 mm hard metric cartridgesThe plug-in units in the 2 mm hard metric cartridges connect to the motherboards of the cartridges through hard metric connectors, which are designed in accordance with the IEC 1076-4-101 standard. Empty plug-in unit slots of the 2 mm hard metric cartridges are covered with dummy panels.

In the network element deliveries, the 2 mm hard metric cartridges come in four sizes:

• 1/2-shelf cartridge, comprising type CM2C-A • 1/3-shelf cartridge, comprising type CC3C-B, CC3C-A • 1/4-shelf cartridge, comprising types CC4C-A, GT4C-A, SW1C-C, and SW10C-A • 1/6-shelf cartridge, comprising types GT6C-A, and LASWC-A

Figure 11 2 mm hard metric cartridge and the cartridge shelf

Euroconnector cartridgesThe Euroconnector cartridges house, for example, the Exchange Terminals, interwork-ing equipment, and clock equipment. The plug-in units in the Euroconnector cartridges connect to the motherboards of the cartridges by standard Euroconnectors.

In the network element deliveries, the Euroconnector cartridge comes in two sizes:

• 1/2-shelf cartridge, comprising type ET4C-B • 1/6-shelf cartridges, comprising type CLOC-B, CLAC-B

3.3 Plug-in unitsThe plug-in units fall into two categories: plug-in units in 2 mm hard metric cartridges and plug-in units in Euroconnector cartridges.

Mechanical construction of plug-in units in 2 mm hard metric cartridgesThe plug-in units in 2 mm hard metric cartridges are designed according to advanced construction principles based on the IEEE P1101.10 standard. The 2 mm hard metric cartridge environment sets somewhat stricter requirements for the construction of the hardware than that of a standard computer cartridge.

For example, the insertion and extraction forces to be managed when installing or removing the plug-in units in 2 mm hard metric cartridges are considerably greater than they are for the 'normal' plug-in units. For a single plug-in unit, the force to be managed may be as high as 400 N, equal to the weight of 41 kilograms. To overcome such forces, the plug-in units in 2 mm hard metric cartridges are equipped with attachment and removal handles at the top and bottom of the front plate for easy installation.

The front panels of the units are made of aluminium or aluzinc plated steel metal. In addition to durability, particular attention has been paid to logical and user-friendly design, with systematical positioning of the LED indicators and switches for easy oper-ation and monitoring of the unit's condition.

As a general rule, connectors for cables entering the equipment in the 2 mm hard metric cartridges are placed on the motherboards of the cartridges; only connectors for service

Mechanical construction of BSC3i and upgrades

terminals, which are needed only for temporary use, are located on the front panels of the plug-in units.

The printed boards of the plug-in units in 2 mm hard metric cartridges are all of an equal size: 233.4 mm x 220 mm (9.2 in x 8.7 in).

Mechanical construction of plug-in units in Euroconnector cartridgesThe mechanical construction of plug-in units in Euroconnector cartridges is based on principles familiar from previous generations of DX 200 products. The plug-in units in Euroconnector cartridges are equipped with lock springs for easy and firm installation in the cartridges.

The plug-in units in Euroconnector cartridges come in a single or double Eurocard size:

• 100 mm x 220 mm (3.9 in x 8.7 in) • 110 mm x 220 mm (4.3 in x 8.7 in); or • 233.4 mm x 220 mm (9.2 in x 8.7 in)

3.4 CablingThe cabling of the network element consists of interconnection (that is, intracabinet and intercabinet) cables and external cables.

The intracabinet cables comprise the cables inside each cabinet (BSCC or BSCD) and cables between BSCC cabinet and the cabling cabinet. They are cut to length and equipped with connectors of either hard metric or Euroconnector type.

The intercabinet cables comprise cables running between BSCC cabinet and BSCD cabinet, between BSCD cabinet and the cabling cabinet, and between the BSC-part and the TCSM-part in the combined BSC/TCSM installation option.

The external cables include:

• E1/T1 cables • external alarm cables • power supply cables • grounding cables • I/O cables • LAN/Ethernet cables • STM-1/OC-3 cables • IP/Ethernet (GigE) cables • X.25 cables (not in S12 deliveries).

The general cabling principles for the network element are the following:

• Intracabinet cables connect plug-in units located inside the same cabinet. • Most intracabinet cables are equipped on the left side of the cabinet, viewed from

the back. There are some exceptions, such as power supply cables and cables con-necting plug-in units located on the same shelf.

• Intracabinet cables may also include cables that are connected either on the other cable end or on both cable ends to the front panels of the plug-in units. These types of cables can be equipped on either left and/or right side of the cabinet. Other cable end can also be on the other side of the cabinet.

Id:0900d8058067fc13Confidential

The S14 upgrade release is built on top of the previous releases. On S14-level, ETIP1-A plug-in unit is introduced to the network element.

Note that all cables (with the exception of power cables, STM-1/OC-3 and GigE cables) entering the cabinets are grounded at the CPGO or the CPRJ45-A at the cabinet top or at the CPETx connector panels at the cabinet top or in the cabling cabinet (CPETS-G, CPETS-E, CPETC-E; CPETS-H, CPETS-F, CPETC-F).

S13 release

In S13 and S12 releases, all cables (with the exception of power cables and STM-1/OC-3 cables) entering the cabinets are grounded at the CPGO the CPRJ45-A at the cabinet top or at the CPETx connector panels at the cabinet top or in the cabling cabinet (CPETS-G, CPETS-E, CPETC-E; CPETS-H, CPETS-F, CPETC-F).

Releases prior to S12

In releases prior to S12, the general cabling principle for the network element is as follows: all cables except power cables entering the BSCC cabinet are grounded at the cabling panels with grounding outlets (CPGO; X.25, trunk circuit cables, and an alterna-tive external alarm input cable) and at the CPRJ45 connector panel (all other cables).

Cabinet configuration and capacity BSC3i and up-grades

4 Cabinet configuration and capacity BSC3i and upgradesThis section describes the dimensions and configurations of the BSCC and the BSCD cabinet, and those of an optional cabling cabinet.

The capacity of the network element is increased by adding functional units to the con-figuration.

S14 release

In S14 release, a number of upgrade options are available from BSC3i to Flexi BSC. This document discusses BSC3i and upgrades (that is, upgraded Flexi BSC). For more information on the first-delivery Flexi BSC cabinet configuration and capacity, see Engi-neering for Flexi BSC.

S13 release

In S13 release, there are no changes in the BSC3i configuration and capacity. However, TCSM capacity is increased by mounting up to two extension cabinets (TCSA 1 and TCSA 2) in addition to old TCSA 0 cabinet to the TCSM3i for combined BSC/TCSM installation option with a BSC3i 1000 as the BSC3i part.

4.1 Cabinet descriptionsThe network element features the base cabinet BSCC, the extension cabinet BSCD, and an optional cabling cabinet CC.

The BSCC and the BSCD cabinet have fixed cartridge configuration. Although they may be only partially equipped, if the operator does not need to utilise the full BSC capacity, each cartridge in the cabinet accepts a functional unit of only certain type. All cartridges are installed in the cabinets at the factory with plug-in units included or without the plug-in units. The equipment configurations are described in more detail in the following sec-tions.

In the S14-level Flexi BSC upgraded from BSC3i, however, the BSCD cabinet is used only for routing external ET interfaces if more ET capacity is needed. In the upgrade deliveries, the plug-in units of most of the functional units of a S12 or S13-level BSCD cabinet are removed but the cartridges are left in the cabinet with shim plates covering the empty cartridges. In other words, the cabinet is equipped only with ETC 0 and ETC 1 (in GT6C-A cartridges) and CLAC 1 (in CLAB-B cartridge) on shelf 1 and ETC 2 to ETC 5 (in GT4C-A cartridges) on shelf 2.

The cabling cabinet contains five connector panels that are installed in the cabling cabinet at the factory.

4.1.1 CabinetsThe dimensions of the BSCC and BSCD cabinet (IC209-A) are (H × W × D) 2000 mm × 900 mm × 600 mm. The depth of the cabinet doors is included in the depth measure. When installed, the cabinet stands on approximately 50-mm-high adjustable feet or rails.

The dimensions of the cabling cabinet (IC203-A) are (H × W × D) 2000 mm × 300 × 600 mm. The depth of the cabinet doors is included in the depth measure. When installed, the cabinet stands on approximately 50-mm-high adjustable feet or rails.

Cabinet configuration and capacity BSC3i and up-grades

In releases prior to S12, the CPRJ45 is located in the middle and the two cabling panels with grounding outlets (CPGO) on both sides as seen from the front.

Both the CPRJ45-A and the CPRJ45 are used for providing external LAN connections, serial connections, external synchronisation input connections and external alarm con-nections.

Small CPETx (optional)

The CPETS-G, CPETS-E or CPETC-E is used for ET connections. CPETS-G and CPETS-E provide connections with RJ45 connectors. CPETS-G provides two external PCMs from one RJ45 connector, which reduces site cabling by half compared to CPETS-E. CPETS-E provides only one external PCM from one RJ45 connector and fulfils all line protection requirements in ANSI environment. CPETC-E provides connec-tion with coaxial connectors.

CPGO

On S14 level, the CPGO is used also for routing external multi-mode cabling or copper cabling from the ETIP1-A plug-in unit.

From S12 onwards, the external single-mode cabling or fibre from the ETS2 plug-in units is routed from the ETS2 front panels (SFPS1L modules) to the rear side of the cabinet using the holes on the cartridge shelves 1 and 3 or the hole in the upper air guide of the cabinet and then at the rear of the cabinet to the grounding outlet, CPGO, through it, and onwards to the operator network.

In releases prior to S12, the CPGO is used for lead-in for external cables (ET cables, X.25 cables, and optional external input-type alarm cables). The sheaths of all external cables (E1/T1 cables and X.25 cables and optional alarm cables) must be grounded at CPGO when they leave or enter the cabinet. The cables are stripped, and the EMC gasket clamps the cable sheaths against the panel body.

Note that the CPGO panel is always installed at the site.

CPETS-G, CPETS-E or CPETC-E at the BSCD cabinet top (optional)There are three openings at the top of the BSCD cabinet. The opening in the middle is covered with a plate, and from S12 release onwards, small CPETx connector panels are installed on both sides when the number of external E1 interfaces exceeds 704.

Connector panels in the optional cabling cabinetThe cabling cabinet is needed with the BSCC cabinet when the number of external E1/T1 PCM interfaces in use exceeds 48.

In S12 release and from S12 release onwards, the connector panels in the cabling cabinet come in two sizes: the small CPETx panels (CPETS-G, CPETS-E, and CPETC-F) are used for 48 PCMs, and the large CPETx panels (CPETS-H, CPETS-F, and CPETC-F) are used for 256 PCMs.

4.1.4 Other items

Cover for cable conduit (COCC)The cover for cable conduit (COCC) is used in the BSCC and BSCD cabinet to protect and section out the power supply equipment.

Power distribution fuse unit (PDFU-B and PDFU-A)To ensure 2N redundancy for the power distribution lines, the BSC3i cabinet is provided with power distribution fuse units located at the top of the cabinet, above the top shelf.

On S12 level, the BSC3i cabinets are provided with two PDFU-B units. Each PDFU-B forms an independent feeding input branches consisting of circuit breakers, diodes, filters, and fuses.

In releases prior to S12, the BSC3i cabinet is provided with two PDFU-B or four PDFU-A units.

Fan tray (FTRB-A and FTRB)To ensure forced cooling, the BSC3i cabinets are equipped with fan trays.

In S12 first deliveries, the BSCC and the BSCD cabinets are equipped with four fan trays (FTRB-A), each of which contains five fans. The FTRB-A is included in the upgrade deliveries as well (that is, when BSC3i 660 is upgraded to BSC3i 1000). The FTRB-As are located in pairs above the shelf housing BCSUs 0 to 2 (FTRBs 0 and 1) and below the shelf housing BCSUs 3 to 5 (FTRBs 2 and 3).

In releases prior to S12, the BSCC cabinet is equipped with four fan trays (FTRB), each of which contains three fans.

Cover plate (COP48T, COP4T) and shim plate (SHIM16T, SHIM4T)The IC209-A cabinet is designed to use forced cooling. To achieve sufficient cooling capacity and upward air flow, the non-equipped CC3C-B or CC3C-A cartridges housing the BCSU units and/or the individual plug-in unit slots are to be covered. There are cover plates and shim plates that are used for this purpose: empty CC3C-B or CC3C-A car-tridges are equipped with cover plates (COP48T) and empty plug-in unit slots are equipped with shim plates or cover plates (SHIM16T, SHIM4T, and COP4T). The COP48T is 48T wide, the SHIM16T is 16T wide, and the SHIM4T and COP4T are 4T wide.

The number of BCSUs used determines the number of COP48Ts needed. When all BCSUs are installed, the COP48Ts are no longer needed.

4.2 Capacity stepsOwing to its modular hardware structure, the BSC3i can be flexibly configured to meet the capacity requirements of individual operators. The call handling capacity of a network element depends on the number of call control computer units in the system on one hand, and on its PCM capacity on the other hand. When it is necessary to increase the capacity, the system can be easily expanded by adding BCSU functional units (note N+1 protection) to the existing configuration.

g When the minimum configuration, that is, BCSU 1+1 is used, during BCSU switchover there will be a mimimum of 5-10 seconds break on A interface and all ongoing calls will be dropped. A interface break may last even a couple of minutes if a large radio network is in use. A interface break can only be avoided when there is at least BCSU 2+1 con-figuration in use.

Cabinet configuration and capacity BSC3i and up-grades

Upgraded Flexi BSCOn S14 level, Flexi BSC is introduced. This document, however, discusses only Flexi BSC upgraded from BSC3i. For more information on the first-delivery Flexi BSC, see Engineering for Flexi BSC.

In the upgraded Flexi BSC, a maximum of seven BCSU functional units (1 + 6) are installed in the BSCC cabinet. The BCSUs that are not in use are covered with COPT48T cover plates. The minimum configuration is two BSCUs (1 + 1 BCSU with capacity of 500 TRX). The capacity can be increased in steps of one functional unit (500 TRX) at a time, and the maximum capacity of an upgraded Flexi BSC is 3000 TRX.

In upgraded Flexi BSC, the BSCD cabinet is used only for routing ET interfaces and so there are no BSCU functional units in the BSCD cabinet.

BSC3i 1000/2000In S12 release deliveries, BSC3i 1000 and BSC3i 2000 are introduced.

BSC3i 1000 features one cabinet, the BSCC, and BSC3i 2000 features two cabinets, the BSCC and the BSCD. The capacity of the cabinets is increased in five steps, one BSCU functional unit (200 TRX) at a time. The BCSUs that are not in use are covered with COPT48T cover plates. The minimum configuration of BSC3i 1000 features one cabinet with a minimum number of BCSU functional units, that is, with two BCSUs (1 + 1 BCSU with capacity of 200 TRX). The maximum configuration of BSC3i 2000 features two cabinets with a maximum number of BCSUs, that is, with eleven BCSUs (10 + 1 BCSUs with maximum capacity of 2000 TRX).

BSC3i 660The minimum configuration of the BSC3i 660 features one BSCC cabinet with a minimum number of BCSU functional units, that is, two BCSUs (1 + 1 BSCU with capacity of 110 TRX). The BCSUs that are not in use are covered with COPT48T cover plates. The capacity can be increased in steps of one functional unit (110 TRX) at a time. The maximum number of BCSUs in BSC3i 660 is seven (6 + 1) and the maximum capacity is 660 TRX.

4.3 TCSM3i for combined BSC/TCSM installation optionThe TCSM3i part of the TCSM3i for combined BSC/TCSM installation option is a third-generation transcoder submultiplexer (TCSM3i). It is connected to the BSC-part (BSC3i 1000/2000) at the BSC3i site. On S13 level, however, extension cabinets (TCSA 1 and TCSA 2) can be connected to BSC3i 1000 only.

Note that in S14 release deliveries, the use of Flexi BSC (first-delivery or upgraded Flexi BSC) as the BSC-part decreases the capacity by 500 TRX per TCSM3i cabinet.

For more information on TCSM3i for combined BSC/TCSM installation option, see the separate document Engineering for TCSM3i.

5 Functional unit descriptions for BSC3i and upgradesThe functional unit types of the BSC3i and the Flexi BSC upgraded from BSC3i network elements are described in the following sections. Each description includes the informa-tion on the basic configuration of the functional unit and the expansion possibilities, if such exist. The descriptions are presented in alphabetical order except for the PDFU, which is presented last.

Note that this document discusses BSC3i and its upgrades (upgraded Flexi BSC); for more information first-delivery Flexi BSC, see Engineering for Flexi BSC.

The following functional units are used in the BSC3i and its upgrades:

• Bit group switch (GSW2KB/GSW1KB/GSWB) in the network element • BSC signalling unit (BCSU) in the network element • Clock system in the network element • Ethernet-based message bus (EMB) in the network element • ETIP and EET in the network element - introduced on S14 level • Exchange Terminal (ET) in the network element • IP interfaces in the network element • Marker and cellular management unit (MCMU) in the network element • Message bus (MB) in the network element • Operation and maintenance unit (OMU) in the network element • STMU and SET in the network element • Power distribution fuse unit (PDFU) in the network element

General configuration rulesThere are some general rules in configuring the network element:

• Shim plates are used for covering empty slots in each computer cartridge and cover plates are used to cover empty BCSU cartridges.

• Memory modules are installed into the central processor unit (CPU). Depending on memory requirements, the type of memory module and the number of modules needed is selected (1 x 1 GB, 2 x 512 MB, 512 MB, 2 x 256 MB).

• Configuration of the functional units must be done according protection principles.

5.1 Bit group switch (GSW2KB/GSW1KB/GSWB) in the network elementThe following sections describe bit group switches GSW2KB, GSW1KB, and GSWB.

5.1.1 GSW2KB, 2048 PCM bit group switch

The equipment of the GSW2KB functional unit is housed in an SW10C-A cartridge. The configuration of a GSW2KB in BSC3i includes eight SW256B switching units per SW10C-A cartridge.

Separate power supply plug-in units are not needed in GSW2KB because the SW256B plug-in unit has a built-in power supply.

Because of protection requirements, the BSC3i always contains two GSW2KBs. The GSW2KB equipment housed in the SW10C-A cartridge and the basic configuration is shown in figure GSW2KB equipment in the SW10C-A cartridge and table Plug-in units of the GSW2KB in an SW10C-A cartridge.

Figure 18 GSW2KB equipment in the SW10C-A cartridge

Purpose: The duplicated 2048 PCM bit group switch is the switching fabric of the BSC3i. The GSW2KB is housed in two identical SW10C-A cartridges. It conveys the traffic passing through the BSC3i and switches the tones to the subscribers and to the trunk circuits. It also establishes the needed connections to the signalling units and the internal data transmission channels, and is responsible for the submultiplexing functions of the BSC3i.

The operation of the GSW2KB is controlled and supervised by the marker and cellular man-agement unit (MCMU; two SWCOP-As).

Note that in S14-level Flexi BSC upgrade deliveries, one SWPRO-C is used in MCMU instead of two SWCOP-As.

Functional unit descriptions for BSC3i and upgrades

S12 release upgade BSC3i 660 deliveries with AS7-C plug-in unitsOn S12 level, memory upgrade is mandatory. In other words, there must be two MR256M modules in slot F10 instead of one when the CP710-AB, CP710-AC or CP710-A is used. When the memory capacity of the BSC3i (660) is upgraded to S12 level, but no BSC3i 660 to BSC3i 1000 upgrade is done, the number of AS7-C plug-in units remains unchanged (1) in the BCSU, see BCSU S11.5 with AS7-C.

S12 release BSC3i 660 deliveries with AS7-B plug-in unitsOn S12 level, memory upgrade is mandatory. In other words, there must be two MR256M modules in slot F10 instead of one.

When the BSC3i (660) is delivered with AS7-B plug-in units, the configuration of the BCSU is the same as presented in BCSU S11.5 with AS7-B.

5.2.5 Releases prior to S12The minimum number of BCSUs in the BSC3i (in one BSCC cabinet) is two; the maximum number is seven. The BCSU equipment is housed in the CC3C-A cartridge.

t Because of general N+1 protection principle of the fault tolerant DX 200 computing plat-form, equal number of AS7 plug-in units must be configured in every BCSU unit. This means that all BCSUs have to include either 3 x AS7-B plug-in units (standard S10.5 configuration) or 1 x AS7-C plug-in unit (standard S11 configuration). Therefore S10.5-based hardware configurations have to be extended with S10.5-based BCSU hardware extensions and S11-based hardware configurations have to be extended with S11-based BCSU hardware extensions.

5.4 Ethernet-based message bus (EMB) in the network element

In S14 Flexi BSC upgrade deliveries, note that

• only EMB is in use • only ESB24-D is in use in MCMU

In BSC3i 1000/2000 on S12 level, Ethernet-based message bus (EMB) replaces MB used by the BSC3i 660.

The EMB is a new type of message bus designed for the DX 200 network elements. The EMB uses a switched LAN, whereas the MB uses a shared bus. Despite the difference, the applications that work correctly on top of MB, also work correctly on top of EMB without modifications.

The plug-in unit used for the cabinet-level LAN switching unit is ESB26 or compatible. The ESB26s for EMB are installed in the MCMU. All computers can be connected to one ESB26 pair.

The plug-in unit required for the central processor units is CP816-A, CP816-AC or com-patible, with four Ethernet ports. EMB-specific address modules are installed in the pro-cessor units.

All connections are full duplex. The speed of the links between computers and cabinet-level LAN switching units is 100 Mbps (1000 Mbps for the MCMU) because of the limi-tation in the Ethernet link capacity. To achieve protection, EMB LAN hardware is dupli-cated.

5.5 ETIP and EET units in the network elementIn S14 deliveries, Exchange Terminal for IP Transmission (ETIP1-A) is introduced. It is represented by two functional units, Exchange terminal for IP transmission unit (ETIP) and Ethernet Exchange Terminal unit (EET).

S14 deliveries include both BSC3i 1000/2000 deliveries and BSC3i to Flexi BSC upgrade deliveries. The upgrade deliveries can be either software upgrades or hardware upgrades or both. The tables in the following subsections show GTIC 0 and GTIC 1 cartridges when transmission protection is used and when equipment protection is used.

Purpose: The EMB is the new physical connection between the computer units of the network element.

Protection: 2N

Type: Functional unit with no subunits

Plug-in Units ESB24-D in MCMU of Flexi BSC upgraded from BSC3i /

ESB26 in MCMU of BSC3i 1000/2000

Interfaces: CP816-A or CP816-AC in BCSU, MCMU and OMU (from S13 first deliveries onwards)

Purpose: ETIP represents a functional unit of ETIP1-A plug-in unit, and EET represents functional unit of a physical GigE Ethernet interface, that is, a port in ETIP1-A plug-in unit

Protection: Transmission protection

In S14 Flexi BSC upgrade deliveries and BSC3i 1000/2000 deliveries, transmission pro-tection is the default protection method.

Only even ETIP indexes are used. The number of ETIP units with transmission protec-tion is 0-8 (can be increased in steps of one unit at a time) when maximum ET connec-tivity is in use per ETIP1-A plug-in unit (both Hotlink pairs cabled).

The number of EET units having transmission/line protection in S14 Flexi BSC upgrades 0-16 (can be increased in steps of one working and one protecting unit at a time) when maximum ET connectivity is in use per ETIP1-A plug-in unit (both Hotlink pairs cabled).

All EETs have a unique indexes of their own. Both even and odd EET indexes are used. Active and standby EET units are on same ETIP1-A plug-in units. With transmission pro-tection, a maximum of four ETIP1-A plug-in units are equipped to both GTIC cartridges and maximum ET connectivity is in use per ETIP1-A plug-in unit (both Hotlink pairs cabled).

The following table shows ETIP indexes and EET & ET numbers and control PCMs in GTIC 0 & GTIC 1 cartridges when transmission protection is in use and when maximum ET connectivity is in use per ETIP1-A plug-in unit (that is, both Hotlink pairs cabled).

The number of EET units with equipment protection in S14 upgraded Flexi BSC is 0-16 (can be increased in steps of 2 units at a time; one in working ETIP and one in protecting ETIP).

All EETs have a unique index of their own. Only even EET indexes are used. Active and standby EET units are on different ETIP1-A plug-in units (active EET on active ETIP1-A and standby EET on redundant ETIP1-A).

With equipment protection, a maximum of eight ETIP1-A plug-in units are equipped to both GTIC cartridges (powered by different PDFU-Bs) and maximum ET connectivity / Ethernet/IP capacity is in use per ETIP1-A plug-in unit (both Hotlink pairs cabled). Only the first EET from the ETIP1-A plug-in units is used in equipment protection.

The four first active ETIPs are equipped to GTIC 0 slots 01-04 and their protecting ETIPs are equipped to GTIC 1 slots 01-04. The last four active ETIPs are equipped to GTIC 1 slots 05-08 and their protecting ETIPs are equipped to GTIC 0 slots 05-08.

Mixed plug-in unit configurationMixed plug-in unit configurations are also possible in the GTIC 0 and GTIC 1 cartridges; for example:

• ET16 and ETIP1-A • ETIP1-A and ETS2

5.6 Exchange Terminal (ET) in the network elementThe ET16 plug-in unit can change ETSI frame structure to ANSI frame structure in the ANSI environment, and ANSI frame structure to ETSI frame structure in the ETSI envi-ronment.

In S14 upgrade deliveries, different Flexi BSC network elements are available for the E1 environment (ETSI with transmission rate 2 Mbit/s) and T1 environment (ANSI with transmission rate 1.5 Mbit/s). Since the ET16 plug-in units provide an interface for the network element PCMs to the environment, the connector panels at the equipment cabinet top or in the cabling cabinet the ET16s connect to have to match the environ-ment the network element is used in. The panels at the equipment cabinet top are ordered separately but the panels in the cabling cabinet come with the cabinet.

There are three alternatives for cabling cabinets:

• cabling cabinet, 2 PCMs / cable (balanced CPETS-G; CPETS-H) • cabling cabinet, 1 PCM / cable (balanced CPETS-E; CPETS-F) • cabling cabinet, coaxial PCMs (unbalanced CPETC-E; CPETC-F)

From S12 onwards, ET16 plug-in units are used. They are housed in GT6C-A and GT4C-A cartridges and used in both ETSI and ANSI environments. However, the con-nector panels at the equipment cabinet top or in the cabling cabinet they connect to have to chosen so that they match the environment the network element is used in.

In releases prior to S12, the exchange terminals match the environment of the network element they are used in: ETSI versions of the ET plug-in units (for example, ET4E or

ET4E-C) are used in the E1 environment, while the T1 environment required the use of ANSI version units (for example, ET4A). The ETs of the BSC3i are housed in ET4C car-tridges with two shelves. One shelf can be housed with ET4s or ET2 units with GSW1KB in S11.5. The selection between the ET4s and ET2s is made with the jumpers of the SW128B units.

5.6.1 Exchange Terminal ET16 The 2048 PCM bit group switch GSW2KB is a prerequisite for the implementation of ET16 exchange terminals in BSC3i 1000/2000.

The ETs are housed in GT6C-A or GT4C-A cartridges. One ET16 plug-in unit contains 16 ET functional units, and an "ETC unit" cartridge can contain up to four (GT6C-A) or eight ET16 plug-in units (GT4C-A).

The total number of ET plug-in units in the BSC3i with GSW2KB is 50 and the total number of ETs is 800 (50 × 16).

The plug-in units are equipped in GT6C-A cartridges (ETC 0 and ETC 1), and in GT4C-A cartridges (ETC 2 to ETC 5). Figure ET16 in GT6C-A and in GT4C-A cartridge shows the cartridges.

Purpose: The Exchange Terminal (ET) performs the electrical synchronisation and adaptation of external PCM lines. It performs the AMI or B8ZS (ET4A), or HDB3 (other ET16 plug-in units) coding and decoding, inserts the alarm bits in the outgoing direction and produces PCM frame structure.

Protection: None

Functional unit descriptions for BSC3i and upgrades

The SWU provides access to the operator's IP network as a first level LAN switching unit. It provides up-link interfaces to the IP network (router) or to an additional LAN switching unit through the BSC3i connector panel. The SWU collects data from the computer and packet controller units and sends it further to external routers and the IP network through 1 Gbit/s (ESB24-D/ESB26 only) or 100 Mbit/s up-link connections. Redundant LAN switching units provide ports of 10/100/1000Base-T/-Tx interfaces with RJ45 connectors and 1000Base-Sx interfaces with LC connectors through the BSC3i connector panel.

One LAN SWU pair is dedicated to collecting user-plane traffic from Packet Control Units (PCU) and another to collecting data from computer plug-in units (CPU).

Basic S12 upgrade deliveriesS12 level functionalities require 512 Mbyte memory in the CP710-A, CP710-AC and CP710-AB central processor plug-in units, and therefore two MR256M memory modules must be installed in slot F7 even if BSC3i 660 to BSC3i 1000 upgrade is not made.

It is not necessary to replace ESB20-As with ESB26s, if the ESB20-As have been installed in the MCMU in releases prior to S12.

S12 BSC3i 660 deliveriesIn S12 BSC3i 660 deliveries, the CC4C-A cartridge contains:

• one CP710-AB or CP710-AC (with two MR256M memory modules) • one SWCOP-A • two MBIF-Bs • one PSC6-A • two ESB26s (S11.5 deliveries) or ESB20-As (S10.5 deliveries)

5.9 Message Bus (MB) in the network element

Note that Message Bus (MB) is not used in the S14 Flexi upgrade deliveries.

From S12 onwards, the shared message bus (MB) is used in the BSC3i 660 only.

The duplicated MB has a transfer rate of 32 Mbit/s. It is controlled by the Message Bus Interface plug-in unit (MBIF-B), which also acts as a bidirectional interface between the microcomputer and the 16-bit parallel MB.

The power supply to the MB terminal resistors at each end of the bus is backed up by a cable which runs between the cartridge housing the terminal resistor and another car-tridge on the same shelf.

5.10 Operation and maintenance unit (OMU) in the network element

Purpose: MB is the physical connection between the computer units of the network element. It is con-trolled by the Message Bus Interface plug-in units (MBIF-B) located in every computer unit.

Protection: 2N

Type: Functional unit with no subunits

Plug-in Units MBIF-B in every computer unit

Interfaces: Host computer units of the MBIF-Bs

Purpose: The Operation and Maintenance Unit (OMU) acts as an interface between the user and the BSC3i and takes automatic recovery measures on the basis of its collected fault data when required. The tasks of the OMU can be divided into five groups:

• LAN supervision and LAN topology management

• traffic control functions

• maintenance functions

• system configuration administration functions

• system management functions

The OMU has dedicated storage devices, which serve as a storage, for example, for the entire system software of the network element as well as for the event buffer for intermediate storing of alarms.

Protection: -

The network element contains one OMU - so there is no protection.

5.10.1 S14 releases

S14 from BSC3i 1000/2000 to Flexi BSC upgrade deliveriesIn S14 Flexi BSC upgrade deliveries - when BSC3i 1000/2000 is upgraded to Flexi BSC - the OMU equipment to be upgraded may be old or new (introduced in S13 deliveries).

For information on BSC3i upgraded to Flexi BSC, see figure New OMU equipment in Flexi BSC upgrade deliveries and tableOperation and Maintenance Unit i (OMU) in upgraded Flexi BSC with new equipment and figure Old OMU equipment in Flexi BSC upgrade deliveries and tableOperation and Maintenance Unit (OMU) in upgraded Flexi BSC with old equipment

Note that HWAT-B is available from 10/2009 onwards.

Note that AS7-C plug-in units are not automatically replaced with AS7-D in S14 upgrade deliveries. If more capacity is needed, an upgrade is possible. In that case, however, the AS7-D plug-in units have to be ordered separately.

5.10.2 S13 releasesNote that HWAT-B is available in S13 release deliveries from 10/2009 onwards.

The S13 first-delivery OMU is equipped with a new mass memory and therefore the plug-in units are reorganised in the CM2C-A cartridge in the following way:

• the digital X.25 interfaces are provided by the use of optional AS7-C plug-in units in slots 04 and 05 (as in S12)

• the SERO-B and HWAT-A are in slots 06 and 07, respectively (as in S12) • the DX 200 carrier for AMC DCAR1-A in the space of slots 08 and 09 • a USB memory stick is plugged to the front panel of the DCAR1-A is used for

software package transfer and software back ups • two SAS hard disks 73 GB HDS07-A / SAS hard disks 147 GB HDS14-A with AMC

carriers for hard disks HDSAM-A are plugged in AMC slots provided by DCAR1-A • a new CPU plug-in unit, the CP816-AC in slot 10, is used instead of the CP816-A,

because the new mass memory does not require an SCSI capable CPU plug-in unit

5.10.3 S12 releases

S12 first deliveryDuring the second half of 2008, S12 new delivery is harmonised to have the same content as S13 new delivery has, that is, the new OMU equipment.

In S12, the OMU equipment is housed in the CM2C-A cartridge. Because of higher capacity requirements, the analog X.25 interfaces are no longer in use.

On S12 level, the plug-in units are reorganised in the CM2C-A cartridge, and

• since the analogue X.25 interfaces are no longer in use in the BSC3i 1000/2000, the digital X.25 interfaces are provided by the use of optional AS7-C plug-in units in slots 04 and 05

• a new variant of SERO plug-in unit, the SERO-B, is taken into use • the MBIF plug-in units removed from the configuration because of the implementa-

tion of the Ethernet-based message bus • a new CPU plug-in unit, the CP816-A, and its memory module (MRD512A) is taken

into use.

Figure OMU equipment in the CM2C-A cartridge (S12) shows the basic configuration of OMU and table Plug-in units of the OMU, S12 lists the plug-in units.

Figure 50 OMU equipment in the CM2C-A cartridge (S12)

Notes

1) If no AS7-C is equipped, SHIM4T remains equipped in this slot.

2) One 2 Mbit/s is used together with the other Digital X.25 interface AS7-C in adjacent slot; the other 2 Mbit/s is left unused.

5.11.1 S14 releasesS14 deliveries include both BSC3i 1000/2000 deliveries and BSC3i to Flexi BSC upgrade deliveries. The tables show GTIC 0 and GTIC 1 cartridges when transmission protection is used and when equipment protection is used.

The ETS2 plug-in units providing the STMUs and SETs are housed in GTIC 0 and GTIC 1 cartridges. The cartridges can contain up to

• four ETS2 plug-in units (transmission protection) • eight ETS2 plug-in units (equipment protection)

Transmission protectionThe following figure and table show ETS2 plug-in units in GTIC 0 and GTIC 1 cartridges when transmission protection is in use.

Purpose: In S12, there are two ways to equip ETS2 plug-in units into GTIC cartridges:

• The default way is to equip four ETS2 plug-in units to both GTIC cartridges (GTIC car-tridges powered by different PDFU-Bs) and to use both STM-1/OC-3 interfaces (two active and two standby SETs per STM-1/OC-3 interface) of ETS2 plug-in units.

• The alternative way is to equip eight ETS2 plug-in units to both GTIC cartridges (GTIC car-tridges powered by different PDFU-Bs) and use only the first one of the STM-1/OC-3 inter-faces (active SET + standby SET) of ETS2 plug-in units.

The optical interface from the front panel of the ETS2 plug-in unit is cabled through the CPGO at the cabinet top.

One STMU unit (that is, one ETS2 plug-in unit) has four SETs in use in the default alternative presented above and in the other alternative one STMU unit (that is, one ETS2 plug-in unit) has two SETs in use.

In optical interface protection, only even STMU indexes are used; either four (by default) or eight (alternative) in both cartridges (GTIC 0 and GTIC 1).

Figure 55 ETS2 plug-in units in GTIC 0 and GTIC 1 cartridges when transmission protection is in use

In S14 BSC3i first deliveries and in S14 Flexi BSC upgrade deliveries, transmission pro-tection is the default protection method.

Only even STMU indexes are used for STMU. The number of STMU units with trans-mission protection in S14 upgraded Flexi BSC is 0-8 (can be increased in steps of one unit at a time) when both STM-1/OC-3 interfaces are used per ETS2 plug-in unit (that is, both Hotlink pairs are connected).

The number of SET units with transmission protection in is 0-32 (that is, 16 active and 16 standby; can be increased in steps of one active and one standby unit at a time).

All SETs have a unique index of their own. Both even and odd SET indexes are used.

Active and standby SETs are on same ETS2 plug-in units.

In S14 BSC3i first deliveries and in S14 Flexi BSC upgrade deliveries, equipment pro-tection is an optional protection method.

Both even and odd STMU indexes are used for STMU. The number of STMU units with equipment protection is 0-16 (can be increased in steps of one pair at a time).

All SETs have a unique index of their own, and only even SET indexes are used. The number of SET units with equipment protection is 0-32 (can be increased in steps of two units at a time - one in working STMU and one in protecting STMU).

Active and standby SETs are on different ETS2 plug-in units - active SET on active ETS2 and standby SET on protecting ETS2.

In equipment protection, a maximum of eight ETS2 plug-in units are equipped to both GTIC cartridges (powered by different PDFU-Bs) and both STM-1/OC-3 interfaces of ETS2 plug-in units are used as follows:

• The first four active STMUs are equipped to GTIC 0 slots 01-04 and the correspond-ing protecting STMUs are equipped to GTIC 1 slots 01-04.

• The last four active STMUs are equipped to GTIC 1 slots 05-08 and the correspond-ing protecting STMUs are equipped to GTIC 0 slots 05-08.

Mixed plug-in unit configurationMixed plug-in unit configurations are also possible in the GTIC 0 and GTIC 1 cartridges; for example:

• ETS2 and ET16 • ETS2 and ETIP1-A • ETIP1-A and ET16

5.11.2 S13 and S12 releasesIn S13 and S12, the new 2048 PCM bit group switch GSW2KB is a prerequisite for the use of SDH/SONET Exchange Terminal (SET). One ETS2 plug-in unit forms a STMU functional unit. Depending on configuration, each STMU consists of two or four SETs. One SET consists of 63 STM-1 (ETSI) / 84 OC-3 (ANSI) ETs.

The SETs, both active and standby, are installed in the GT4C-A cartridges. The number of SET units with an optical interface protection in S12 first deliveries is from 0 to 32 (16 active and 16 standby; in steps of one active and one standby at a time). All SETs have a unique index of their own.

The GT4C-A cartridges can contain up to eight ETS2 plug-in units, each containing two SET functional units.

To ensure 2N protection for the power distribution lines, the BSC3i cabinets are provided with two PDFU-B or four PDFU-A units, which are located in the upper part of the cabinet and installed at the factory. One PDFU-B contains two independent functional units within one case, A and B. The feed cables are also duplicated.

Each half of PDFU-B and each PDFU-A forms an independent feeding input branch con-sisting of:

• connectors and circuit breakers for the incoming power cables • an integrated filter for EMC protection • connectors for alarm and outgoing power cables • fuses for outgoing distribution cables

• each half of a PDFU-B contains ten fuses • the PDFU-A contains eight fuses

• indicators for blown fuses

The circuit breakers for the incoming power cables have a 30 A rating for PDFU-B and 20 A rating for PDFU-A and the fuses for the outgoing distribution cables a 10 A rating (use part with manufacturer code 10511 20121).

Overview of BSC3i installation site for BSC3i and up-grades

6 Overview of BSC3i installation site for BSC3i and upgradesThis section briefly describes the equipment room layout and some basic requirements for the premises.

6.1 Equipment room layoutEach cabinet should be located in the equipment room with free space of at least 900 mm (35.4 in.) both at the front and the back, and at least 500 mm (20 in.) between the end of a cabinet row and the wall. The recommended space between the cabinet rows is 1000 mm (39.4 in.) or, when the equipment room has a raised floor, 1200 mm (47.2 in.). Any deviations from the above must be agreed upon individually.

In layout planning, the following aspects should be considered:

• cable structures for the power supply and PCM circuit cables • room for expansion cabinets • room for maintenance between two two-cabinet units with SCCs (when the equip-

ment room has a raised floor) • free space above the cabinet rows (height at least 500 mm, or 20 in.)

Figure Layout principles shows the layout principles for Flexi BSC, BSC3i, TCSM3i for stand-alone option and TCSM3i for combined BSC/TCSM installation option.

6.2 Cable structures and estimated power consumptionFor more information on the cables and cable structures, see Installation Site require-ments fro Base Station Controller and Transcoder.

Cables of peripheral devicesThe connectors for the VDUs and LPTs used for temporary service operations are on the front panels of the CPU plug-in units. The cables connect to RJ45 connectors.

The permanent VDU and LPT connections for monitoring the operations of the units are made through the CPRJ45-A connector panels (from S12 release onwards) or CPRJ45 connector panels (releases prior to S12) in the BSCC cabinet.

Engineering for BSC3i and Upgrades Alarm system for BSC3i and upgrades

Id:0900d8058065f186Confidential

7 Alarm system for BSC3i and upgradesThe task of the alarm system is to process the alarm signals collected from the network element and find the basic fault or disturbance behind the alarm condition. The alarm system localises the unit in which a disturbance or a fault has been generated, after which the appropriate automatic recovery functions can be activated. The user is informed of failure conditions with alarm printouts and External Alarm Unit (EXAU-A) controls. The alarm system stores all alarm events on a disk. Alarm history stored on the disk can later be examined with the user terminal.

Alarm functions of the system include:

• collection of alarm data • storing of alarm data • output of alarms • control of alarm printouts

With the user interface, it is possible to cancel or block alarms, output alarm history, and change alarm-specific parameters and EXAU-A controls. See figure Implementation model of the alarm system.

Figure 69 Implementation model of the alarm system

7.1 Collection of alarmsThe alarm data can be divided into the following subgroups:

• hardware alarms • fault observations of the program blocks • fault observations of the preprocessors

All the fault observations and alarms of the network element are saved in the log file of the alarm system.

Alarm system for BSC3i and upgrades

Hardware alarmsSupervision logic has been integrated into some types of hardware. The supervision logic can inform the alarm system about malfunctions in the hardware. The following devices have supervision logic:

• power sources • plug-in units which need basic timing signals for their timing

In addition, the following are supervised by the hardware:

• fuses • premises

In the BSC systems, the hardware alarms of the cartridges are wired to the CLOC car-tridge, from which they are relayed to the plug-in unit HWAT in the OMU cartridge. The alarms are transmitted to normal processing by the alarm system from the HWAT by the software.

Fault observations of the softwareThe observations can be passing disturbances detected in the system, ON/OFF-type alarms, or updates of the error ratio counters. The error ratio counters are used to collect information about statistical errors.

Fault observations of the preprocessorsEach preprocessor supervises its own function and environment. The alarm system provides a service to the preprocessors for sending their alarm data directly to the alarm system. The fault observations of preprocessors (AS7, for example) are transmitted to the alarm system through an application program block.

7.2 Alarms from the TCSM3iThe BSC assigns an identity, a time stamp, an alarm class, a text string, and a physical location to each alarm. The BSC stores information on the physical location of each piece of the TCSM3i equipment. It converts the logical location information of the TCSM3i alarms into a physical address. Alarms which indicate that traffic channels, trunks, or other portions of the traffic capacity are lost because the BSC blocks the respective elements. The TCSM3i is not itself aware of the blocking measures taken by the BSC.

The user is informed of failure conditions with alarm printouts in the BSC. The alarm system stores all alarm events on a disk. Alarm history stored on the disk can later be examined with the user terminal. With the user interface, it is possible to cancel or block alarms, output alarm history, and change alarm-specific parameters.

7.3 Alarms from the TCSM2Alarms are transferred over the operation and maintenance link to the BSC. Current alarms can, however, be viewed on a local MMI terminal. For immediate understanding at a local MMI terminal, the TRCO software assigns a text string to the alarms.

When the BSC receives alarms indicating that traffic channels, trunks or other portions of the traffic capacity are lost, it immediately blocks the respective elements in its own system. The TCSM2 itself is not aware of the blocking measures taken by the BSC.

7.4 BTS alarm handling in the BSCBTS alarm handling in the BSC collects various fault indications of the system, pro-cesses them, and informs the user of the faults in actual alarm printouts. Moreover, the alarm handling system makes decisions on the basis of alarm indications and activates the radio network recovery when needed, so that the automatic recovery actions are started.

The received BTS alarms are stored in a disk file. The alarm history and the currently active alarms can be displayed with an MML command. The BTS alarm handling MML also allows the user to change certain alarm parameters and to cancel alarms manually.

The alarm handling system receives alarm indications from the following sources in the radio network:

• alarms from the BTS equipment • alarms from the BTS concerning the BTS software • external alarms from the BTS site • alarms concerning PCM lines in the radio network • alarms from LAPD links on the A-bis interface • alarms from A-bis interface equipment

7.5 BSS transmission equipment handlingWhen the equipment is located at a BTS site, the management commands between BSC and BTS are sent via the LAPD based operation and maintenance link. The OMU of the BTS forwards the commands to the managed equipment through the local Q1 bus. Possible equipment types at the BTS site are:

• base station interface equipment (BIE) • transmission unit (TRU) • digital microwave radio link (DMR)

Furthermore, four other pieces of transmission equipment (TE), for example optical line equipment, can be connected to the local Q1 bus at the BTS site.

7.6 Nokia Siemens Networks NetAct network management systemNetAct is a network and service management system, which provides centralised man-agement functions for different network technologies and network domains. The NetAct can manage both the network and the services in a centralised manner, meaning that the operator can view the network element status, service quality indicators and traffic from a single screen. A network-wide view is always available.

A unified mediation and adaptation layer (UMA) is the interface towards the different network subsystems, such as the BSS. The UMA is responsible for collecting data from the BSS, such as alarms, events, and measurements. A unified adaptation to network elements and element managers makes it possible to handle alarms and performance indicators in the same way regardless of technology or origin.

The NetAct consists of functionality areas (for example, monitor, reporter, and planner), which provide management capabilities grouped together according to the most relevant operator processes. For the BSS, there is an extensive set of management functionalities available, for example the following:

• monitoring • reporting • planning • configuring and optimising • system management • service quality management

The hardware solution of NetAct is built of one or more server clusters and operator seats. Regional clusters manage a specific region, while global clusters are intended for centralised network management tasks. When distributing the operations between regional and national management centres, the regional server clusters and third party management systems are connected to the global cluster via a data communication network (DCN). The hardware includes the following:

• high-availability servers (HP-UX) • application servers (Windows and HP-UX) • operator seats • storage area network (SAN) with disk array • DCN backbone

7.7 External Alarm UnitThe network elements can be equipped with an alarm unit to make the alarm monitoring more efficient. The External Alarm Unit EXAU-A (or the earlier variant EXAU) is a small device controlled by the HWAT-A plug-in unit located in the network element. The EXAU-A indicates alarms from the network element with indicator lights and a buzzer.

Note the following:

• EXAU-A is in use in releases from S12 onwards and in S11.5 and S11 first deliveries from 04/2006 onwards

• EXAU is in use in S10.5 deliveries, and in S11 and S11.5 deliveries before 04/2006.

The EXAU-A differs from the earlier variant in the following ways:

• A second D25 in the EXAU-A is used for daisy-chaining outputs to another EXAU-A. • Power on status is indicated by a small low intensity LED (green).

The EXAU-A panel consists of a base assembly and a cover assembly with a compo-nent board attached to it with three attachment pins. The component board accommo-dates also the power supply and alarm connectors. Functionally, the EXAU-A panel consists of the following blocks:

• component board connected to the cover • base frame for mounting on the wall • alarm inputs, D25 connector on the component board • six indicator LEDs connected to the component board • buzzer mounted on the component board • test, buzzer reset, and silent mode buttons connected to the component board • power supply (-48 V)

Alarms that activate the buzzer can be selected with DIP switch SW1. The buzzer is con-nected to six alarm inputs, an so are the indicator LEDs. The buzzer can be switched off by the silent mode button. The test button is used to test the operation of the indicator LEDs and the buzzer.

Power is supplied through a protective switch SW2 and fuse F1. When the cover assembly is opened, the power supply to the EXAU-A unit is disconnected.

Synchronisation for BSC3i and upgrades

8 Synchronisation for BSC3i and upgradesSynchronisation principles on the system levelThe primary synchronisation method in the DX 200 network is based on the so-called master-slave principle. In this method, the network elements in a given network are hier-archically organised in such a way that a network element on a higher level in the hier-archy controls the synchronisation of network element(s) one step below it. A DX 200 network element which is synchronised to higher level equipment can, in turn, function as a synchronisation source for lower level equipment. The synchronisation signals are transmitted through the PCM/SDH lines.

If the connection to the master equipment is broken, the DX 200 equipment can continue operation by switching into plesiochronous mode, that is, by generating their own basic frequency without an external synchronisation reference. When the connection to the master equipment is restored, the equipment will re-synchronise to the synchronisation signal coming from the higher-level exchange or network element.

Architecture of the DX 200 network synchronisationThe DX 200 cellular network synchronisation plan is usually designed in such a way that one of the exchanges in a PSTN or an ISDN network functions as the master exchange and supplies the synchronisation reference to the Mobile Switching Centres (MSCs) in the cellular network. The synchronisation signal is also fed to each MSC from one or more other MSCs of the same network, to ensure the availability of the synchronisation reference in case the connection to the PSTN/ISDN is disrupted.

The MSCs, in turn, supply the synchronisation reference to the DX HRLs (HLRs) of the network, as well as to the base station controllers (BSCs) through the transcoder sub-multiplexers (TCSMs). To ensure protection, each HLR of the network receives the syn-chronisation reference from multiple MSCs, and each BSC from multiple TCSMs.

The protection of the synchronisation reference to the TCSMs and BSCs has been arranged by supplying each reference signal through a separate PCM. Figure Synchro-nisation of the BSC shows the architecture of the network synchronisation system.

Figure 71 Synchronisation of the BSC

Internal synchronisation of the BSC3iEach DX 200 network element has an internal clock generator which receives the refer-ence timing from external synchronisation sources (normally external PCM circuits) and generates pairs of timing signals which are distributed to all other plug-in units in the network element. In the BSC, each pair normally uses the frequencies 8.192 MHz / 8 kHz.

Two clock and tone generator (CL3TG/CL3TG-U) plug-in units are positioned in the CLOC cartridge. Performance characteristics of the CL3TG/CL3TG-U are shown in the following table.

Synchronisation for BSC3i and upgrades

Number of synchronisation inputs for CL3TG/CL3TG-U:

• four for PCM lines • two external inputs (120 Ω balanced / 75 Ω unbalanced) / one external input (120 Ω

balanced / 75 Ω unbalanced)

The line coding/decoding standards shown in the following table are supported for PCM signals.

Note that the PCM cables carrying the synchronisation signal to ET16/ET4/ET2 plug-in units are powered by different power supplies to ensure protection of the power supply.

Management network topology for BSC3i and up-grades

9 Management network topology for BSC3i and upgradesNokia Siemens Networks NetAct offers standard interfaces towards the network ele-ments, the higher-level network management system, and the administrative systems. For more information, see figure NetAct system interfaces.

BSS includes BSC, TCSM (second and third generation transcoder), transmis-sion equipment, and BTS

Figure 72 NetAct system interfaces

The operation and maintenance interfaces between the NetAct and the network elements follow the principles described in the GSM Recommendation 12.01. The protocol stack is implemented in the NetAct for communication between the NetAct and the network elements.

Remote terminal sessions can be established from the NetAct to the DX 200 network elements (BSC, TCSM, MSC). The PAD (packet assembler/disassembler, X.29) protocol over the X.25 connections is used for the remote terminal.

NetAct supports the following physical interfaces:

• X.25 through packet switched network (analog connection - available in releases prior to S12)

• X.25 through time slots reserved from a semipermanently connected PCM link (digital connection)

• LAN

Because BSC releases have introduced more features with increased amount of radio network objects and measurement data, more operation and maintenance link capacity is needed. The minimum operation and maintenance link capacity requirement of 128 kbit/s is feasible no more, and therefore an analog X.25 connection with limited link capacity is available no more in the S12 software release with BSC3i 1000/2000 config-urations.

Digital X.25 connection is still feasible, if multiple 64 kbit/s timeslots are used. However, LAN interfaces are mandatory with data speeds higher than 1024 kbit/s (usually in con-figurations over 1000 TRX). Therefore, a LAN-based operation and maintenance con-nection is a recommended link option method as the most powerful alternative.

Note that in BSCi and BSC2i, operation and maintenance LAN interface requires IP cabling and CPLAN panels as well as external LAN switches and/or routers.

Interface towards the base station subsystemThe interface between the NetAct and the base station subsystem (the BSS) uses the X.25 or LAN connection. The management protocol stack in the BSS follows the princi-ples described in the GSM Recommendations 12.01 and 08.09.

The network management applications in the BSS and in the NetAct use the file transfer, access, and management (FTAM) for file transfer. The common management informa-tion protocol (CMIP) is used for other network management purposes. Some applica-tions use a remote MMI, that is, the network element's local commands are given from a remote site.

The operation and maintenance network is connected to the time slots of the PCM circuit by means of the signalling interface adapter (AS7). To ensure redundancy, a spare time slot can also be allocated for the operation and maintenance connections, which is taken into use when the connection through the main time slot is disrupted.

Interface to the switching subsystemThe interface between the NetAct and the switching subsystem (MSC/VLR and HLR/AC/EIR) uses the X.25 or LAN connection and the PAD (packet assembler/disas-sembler, X.29). The switching subsystem is controlled from the NetAct with a remote MML through the PAD. The switching elements send reports and other output to the NetAct through a protocol on top of the X.25. These outputs can be forwarded to output devices or applications in the NetAct.

The management protocol stack is also implemented in the switching subsystem ele-ments. The FTAM can be used for transferring files between the NetAct and the switch-ing subsystem elements.
