Cisco Systems 15454-DS3XM-12= - DS3 Transmux 12 CKT-I-Temperature

The Cisco® ONS 15454 SONET 12-Port DS-3 Transmultiplexer Card provides a cost-effective high-density DS-3 interface solution for hand-offs between interexchange carriers (IXCs) and incumbent carriers as well as a channelized interface for router WAN connectivity.The Cisco ONS 15454 SONET 12-Port DS-3 Trans-multiplexer Card provides 12 Telcordia- compliant GR-499-CORE DS-3 C-Bit or M2/3 framed interfaces operating at 44.736 Mbps. The card de-multiplexes a channelized DS-3 into 28 DS-1s maps each DS-1 to a VT1.5 then multiplexes the 28 VT1.5s into a VT-mapped STS-1 before hand-off to the Cisco ONS 15454 cross-connect card. The integration of trans-multiplexing capabilities into the Cisco ONS 15454 Multiservice Provisioning Platform (MSPP) reduces the need for outboard M13 multiplexers or wideband digital cross-connect systems to access and groom DS-1 signals from channelized DS-3 interfaces.
