INFORMATION
Overview
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.
