WS-SDH155
General Introduction:
EB-SDH155, STM-1 level multi-business SDH (Synchronous Digital Hierarchy) optical transmission system, its technical performance accords with ITU-T and Chinese SDH standard, has excellences of high integration, perfect structure, flexible network, strong network adapted capability and so on. Device offers double optical ports with 155.52Mb/s, A and B, supports multiplexing of 4/8/16 E1 channels, and owns the functions of ITU-T G.813 standard NE timing, VC-12 across connection and channel protection. EB-SDH155 can be used in the network of point to point, chain or ring as ADM (Add-Drop-Multiplexer) or TM (Terminal Multiplexer).
NE management of EB-SDH155, based on unified NM platform, a NM software designed according ITU-T related protocol, realizes the management in network resource, device configuration, alarm, performance and security, supports unified management of several subnets with independent optical channels, and supports telenet management based on internet.
