Cisco ONS 15454 SONET 12-Port DS-3 Transmultiplexer Cards
PICS Telecom is set to receive in 12 units of the Cisco ONS 15454 SONET 12-port DS-3 transmux cards. These have been very hard to source over the past couple of years. Because of this, the pricing has been very high on the secondary market. With this quantity hitting our shelves, we can be much more aggressive with our pricing. If you currently run 15454 in your network and could find a need for an upgrade or spare, please let us know.
The Cisco ONS 15454 SONET 12-Port DS-3 Transmultiplexer Card (Figure 1) provides 12 Telcordia-compliant, GR-499-CORE DS-3 C-Bit or M2/3 framed interfaces operating at 44.736 Mbps. The card demultiplexes 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 transmultiplexing 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. The 12-port DS-3 transmultiplexer card offers grooming flexibility by supporting two ways to receive the DS-3 signal, ported or portless.
