    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.

    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.

    NE Software

    Figure 5-1System software structure

    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.

    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
