The OSN 2500 works at the 2.5Gbit/s or 622Mbit/s level, inherits all features of the MSTP technology, keeps compatible with traditional SDH and MSTP networks, and integrates the SDH, PDH, DDN, Ethernet, WDM, ATM, IMA, and RPR, ESCON, FICON, FC and DVB-ASI (Digital Video Broadcast-Asynchronous Serial Interface) .
OSN 2500 is used in aggregation layer & access layer, and its service board is compatible with OSN 9560 /7500II /7500 /3500 /2500 /1500. OSN 2500 supports intelligent features, automatic end-to-end service configuration, SLA, traffic engineering, timeslot defragmentation, MESH clock synchronization etc. to enhance network utilization.
The OptiX OSN 2500 intelligent optical transmission system (hereinafter referred to as the OptiX OSN 2500) developed by Huawei is the next-generation intelligent optical transmission equipment.
The OptiX OSN 2500 integrates the following technologies to transmit voice and data services on the same platform with high efficiency:
Synchronous digital hierarchy (SDH)
Plesiochronous digital hierarchy (PDH)
RPR(Resilient Packet Ring)
Asynchronous transfer mode (ATM)
Storage area network (SAN)
Wavelength division multiplexing (WDM)
Digital data network (DDN)
Automatically switched optical network (ASON)
The OptiX OSN 2500 subrack has a one-layer structure. The subrack consists of the slot area for processing boards, slot area for interface boards, slot area for the auxiliary interface board, power supply area and fan area.
1. Auxiliary interface area
2. Interface board area
3. Processing board area
4. Power supply area
5. Fan area
The functions of each subrack area are as follows:
Slot area for the auxiliary interface board: This area is used to house the auxiliary interface board, which provides alarm interfaces, orderwire phone interface, management and maintenance interface, and clock interface.
Slot area for interface boards: This area is used to house the tributary interface boards and Ethernet interface boards.
Slot area for processing boards: This area is used to house the line, tributary and Ethernet processing boards, system auxiliary processing boards and the integrated boards of the cross-connect, timing and SCC units.
Fan area: This area is used to house two fan modules, which dissipate the heat generated by the equipment.
Power supply area: This area is used to house two PIU boards, which are used to supply power to the equipment.
OSN 9560/7500II/7500/3500/3500 II/2500/1500 service board & software are all compatible, significantly reducing OPEX and spare part cost Flexible Configuration OSN 2500 is STM-16/4 compatible, upgradable from 622M to 2.5G Large Grooming Capability OSN 2500 has 60G high order and 20G low order cross-connect capability.
The OptiX OSN 2500 provides the following OAM functions at the equipment layer:
Alarm and performance management: supports the reporting of alarms and performance events. The user can discover and locate the faults on the equipment and on the network in a timely manner.
Laser and optical power management: supports the optical power management at the SDH optical interface and the automatic laser shutdown (ALS) function.
Fault locating and equipment maintenance: provides multiple maintenance measures such as PRBS, ETH-OAM, and TCM. The user can monitor, debug, troubleshoot the equipment conveniently.
Expansion and upgrade: supports the network expansion through board replacement. Supports the in-service software upgrade by using the simulation package loading, diffusion loading, and hot patch loading methods.
