It is a new generation multi-services transmission and access device based on SDH technologies. The function models design adopts G.783 suggestions and provides complete monitor, access, protection, network management and Ethernet access function. SDH155 can provide 2 STM-1 uplink interfaces, 63E1 interfaces and 4 10/100BaseT Ethernet interfaces. It adopts modular structure design for flexible service configurations according to different requirements. It can be used as service access and transmission devices on access layer in the data traffic networks, adopts SNMP network management platform which provides grades powerful management based on Service/Client end mode.
