Overview
FBSDH155 is a STM-1 optical transmission system, whose technical performances are fully complied with ITU-T and SDH recommendations. This system is benefit of high integration, flexible construction and strong network adaptability, etc. FBSDH155 provides two 155.52Mb/s aggregate line interfaces of A and B, possessing the network elements timing function of ITU-T G.813 recommendation, and VC-3/VC-12 full-crossing connection and channel protection function.
FBSDH155 has the following usages: As an ADM, it can be inserted in STM-1 ring which provide 63 * E1 tributaries; As a terminal, it can multiplex 63 * E1 to a line port.
Network element management of FBSDH155 system is based on unified network management platform Fi-View-SDH. Fi-View-SDH is designed in accordance with related recommendations of ITU-T, so as to realize network resources, equipment configuration, alarm, performance and security management; it can support unified management of multiple optical-route non-interconnected sub-net, and support remote network monitoring by way of Internet.
