    As a key member of Baudcom “MetroEdge-Express” SDH/MSPP Product family, BD-STM1-TM series terminal multiplexer delivers bonded E1 lines, Ethernet services and V.35 links over legacy SDH networks. Installed at the customer site or directly on STM-1 access ring,the STM-1 terminal multiplexer leverages the SDH infrastructure for LAN connectivity and Internet access, while providing leased line services to end users.

    The Ethernet frames are encapsulated in SDH frame by using GFP (Generic Frame Protocol) and transported through the SDH network in a VC-12 group, configuring the bandwidth of IP channel in increments of 2Mbps.The SDH STM-1 multiplexer introduces LCAS technology and VCAT technology to benefit the SDH network to better fit busty data traffic. Each Ethernet module groom up to two WANs, aggregating two direction Ethernet services into SDH networks. The PDH traffic and V.35 traffic are mapped into the SDH frame; enabling E1 and V.35 link to support cross connection, and can be terminated at any point on the network.

    The multi-service STM-1 terminal multiplexer provides Console interface for management. The EMS network management system supports remote configuration and monitoring, reducing operating expenses, eliminating technical visit and maximizing network performance and uptime.
