2.3 Built-in WDM Technology
The OptiX OSN 3500 provides a two-channel optical add/drop multiplexing board
MR2A and an arbitrary bit rate wavelength conversion board LWX to implement
built-in WDM function. There are two types of MR2 boards: the MR2A board and
the MR2C board. They are identical in function but are installed in different slots.
These boards have the following characteristics.
The MR2 board adds/drops two adjacent standard wavelengths compliant
with ITU-T G.692 (DWDM), with signals transmitted transparently and
operating wavelength ranging from 1535.82 nm to 1560.61 nm.
The MR2 board serves as an OTM station adding/dropping two channels of
signals.
Two MR2 boards connected in serial can form an OTM station
adding/dropping four channels.
The MR2 board can work with the LWX to form an OADM stationadding/dropping two channels of signals.
The LWX board converts client-side signals into standard wavelength signals
as stated in ITU-T G.692 (DWDM) and transmit the signals transparently.
The LWX board provides 3R function to client-side uplink/downlink signals
(at the rate of 34 Mbit/s2.7 Gbit/s), performs clock recovery and monitors its
rate.
Two types of LWX boards are available: single-fed single receiving and
dual-fed signal selection.
The dual-fed signal selection LWX board supports intra-board protection,enabling optical channel protection with one board. The protection switching
time is less than 50ms.
The single-fed single receiving LWX board supports inter-board protection,
that is, 1+1 inter-board hot backup protection. The protection switching time
is less than 50ms.

2.7.3 Adjustable MS Bandwidth
"MS bandwidth" refers to the number of VC-4s on an MSP ring or the number of
VC-4s on a linear MSP chain.
The OptiX OSN 3500 supports adjustable MS bandwidth without interrupting
services. For an STM-16 two-fibre bidirectional MSP ring, the MS bandwidth is
adjusted between one and eight VC-4s. For an STM-64 two-fibre bidirectional
MSP ring, the MS bandwidth is adjusted between one and thirty-two VC-4s.
2.7.4 Upgrading MS Bandwidth
The OptiX OSN 3500 supports upgrading MS bandwidth by replacing it with the
board of higher bit rate without interrupting services. For example, upgrading the
STM-16 two-fibre bidirectional MSP ring to the STM-64 two-fibre bidirectional
MSP ring.
2.7.5 Squelching Function in Multiplex Section
The OptiX OSN 3500 supports the function of squelching misconnected VC-4
traffic.
Each protection time slot in a multiplex section protection ring is shared by the
traffic from different segments or occupied by extra traffic. With no extra traffic in
the ring, and under the situation that a certain node is isolated because of multiple
points failure, the traffic from different segments of the same time slot may
contend for the same protection channel time slot. This brings misconnection of
traffic. With extra traffic in the ring, and even under the situation of a single
nodes failure, the traffic from the working channel may also contend for the time
slot of protection channel carrying extra traffic. This also brings misconnection.
To prevent misconnection, every node of the OptiX OSN 3500 has a detailed
connection table. Every node knows the source and sink point of each VC-12,

VC-3, or VC-4 (VC-12 or VC-3 connections must have the same source and sink).
Such information helps APS protocol to tell possible misconnections in advance.
Traffic with the potentiality of misconnection is discarded through inserting
TU_AIS or AU_AIS.
The OptiX OSN 3500 supports the squelching of misconnected VC-12, VC-3 and
VC-4 traffic in 2-fiber or 4-fiber MS ring protection. VC-12 or VC-3 connections
must have the same source and sink.
2.8 TCM
Tandem Connection Monitor (TCM) is a method monitoring bit errors. If a VC-4
passes through several networks, the bit errors of each section can be monitored
through TCM.
The N2SL1, N2SLQ1, N2SL4, N2SLD4, N2SLQ4, N2SL16 and N2SL64 boards
support TCM at higher level.
2.9 Network Management Information Interworking
2.9.1 Interworking at Physical Layer
NM Information Transparently Transmitted by Third Party Equipment
The DCC consists of two parts:
D1D3 bytes, forming a 192 kbit/s channel.
D4D12 bytes, forming a 576 kbit/s channel.
Currently, only the D1D3 bytes are used. The D4D12 bytes are reserved for
higher management requirements.
When there is a piece of third party equipment between the OptiX OSN 3500
systems, the bytes D4D12 will be used by the third party equipment to transmit the
NM information, as shown in Figure 2-6.

Note 1: If the OSN 3500 is configured with EXCSA or UXCSA, only eight optical interfaces can be used when N1SLT1 is inserted
in any one of slots 14 or slots 1516 and twelve optical interface can be used when inserted in any one of slots 58 or slots 1114. If
the OSN 3500 is configured with GXCSA, only four optical interfaces can be used when N1SLT1 is inserted in any one of slots 15
or slots 1416 and twelve optical interface can be used when inserted in any one of slots 68 or slots 1113.
Note 2: The N1SEP1 and N1SEP are the same physically. They are used with the interface board when they are configured as
"N1SEP" on the T2000, or the signal is directly led out from the front panel when they are configured as "N1SEP1".
Note
One OptiX OSN 3500 subrack can configure two 61COA, N1COA or 62COA.

5 Software5.1 Overview
The software system of the OptiX OSN 3500 is of a modular structure, as shown in
Figure 5-1. The software modules fall into three types: the board software, the NE
software and the NM software. The three types of software respectively run on
various boards, the SCC board and the NM computer for corresponding functions.

5.2 Intelligent Software
The intelligent software is included in the NE software. The intelligent software
requires special license, and it can be enabled or disabled independently.
The intelligent software is represented in a control plane which is layered over the
transmission plane. The control plane interacts with the transmission plane to
realise auto-configuration of service and provide service protection based on user
levels. Figure 5-2shows the relationship between the intelligent control plane and
transmission plane.

Figure 5-2Relationship between control plane and transmission plane
The transmission plane manages service configuration of the OptiX OSN 3500 and
provides SDH-based protection for services. The control plane serves as one client
of the transmission plane. Through the interface adaptation mechanism, the
resource agents of the control plane and the transmission plane interact with each
other to get the state of resource allocation and implement function provisioning of
the NE.

5.3 NE Software
The NE software manages, monitors and controls the operation of the boards of an
NE. Through the NE software, the communication unit between the NM system and
boards, the NM system controls and manages NEs. According to ITU-T M.3010,the NE software belongs to the NE management layer in the telecommunication
management network, implementing the functions including NE functions, some of
coordination functions and operating system functions of the network element layer.
The data communication function implements the communication between the NE
and other equipment (including coordinated equipment, NM system, and other
NEs).
Real-time multi-task operating system
The function of the real-time multi-task operating system of the OptiX OSN 3500
NE software is to manage public resources and provide support for the executiveprogram. It provides an executive environment unrelated to processor hardware by
segregating the application from the processor.
Network side (NS) module
The NS module exits between the communication module and equipment
management module. It converts the data format between the user operation side on
the application layer and the NE equipment management layer, and provides
security control for the NE layer. It can be divided into three sub-modules
functionally:
Qx interface module Command line interface module
Security management module.
Equipment administration module (AM)
The equipment AM is the kernel of the NE software for NE management. It
includes Manager and Agent. Administrator can send network management
operation commands and receive events. Agent can respond to the network
management operation commands sent by the network administrator, implement
operations to the managed object and submit events according to status change of
the managed object.
The equipment AM includes configuration management module, performance
management module, alarm management module and MSP switching management
module.
Communication module
This module fulfills the message communication function (MCF) o
