SDH ADM multiplexer ,2×STM-1 interface,E1,Ethernet,V.35

TK-SDH155-AD STM-1 add & drop multiplexer delivers bonded E1 lines, Ethernet services as well as V.35 links over legacy SDH networks. Installed at the customer site or directly on STM-1 access ring,the device leverages the SDH infrastructure for LAN connectivity and internet access, while providing leased line services to end users. Moreover, inter operating with TKSDH-MSAP, it offers aninnovative and competitive solution to reduce OPEX and CAPEX for carriers orISPs.

The Ethernet frames are encapsulated in SDH frame by using GFP(Generic Frame Protocol) and transported through the SDH network in a VC-12group, configuring the bandwidth of IP channel in increments of 2Mbps, with maximum bandwidth up to 100Mbps.

It introduces LCAS technology and VCAT technology to benefit the SDH network to better fit busty data traffic. Each Ethernet module grooms up to four WANs, aggregating four direction Ethernet services into SDH networks. Instead of providing Ethernet services, It also supports E1 and V.35 tributary. The traffic is 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.

It provides two management methods: SNMP and console. The TK communication company central network management system supports remote configuration and monitoring, reducing operating expenses, eliminating technical visit and maximizing network performance and up time.
