3.9 DS3 Transmux and VT Grooming
One of the issues that network planners face is finding a flexible and cost effective transport solution to
extend DS1 services to their networks edge while providing high speed aggregate interfaces to network
switching equipment at the CO. Two of the features the TE-2020 provides are:
• Conversion of VT mapped DS1 services to channelized DS3
• High Density 12 Port DS3 Module
The TE-2020 DS3 TMUX PLM provides low-cost, high-density trans-multiplexing between VT1.5
mapped DS-1 interfaces and M13/C-bit compatible DS3 interfaces. It can operate in two modes (or combi-
nations of the two modes simultaneously).
Physical TMUX mode
In the Physical TMUX mode, each TMUX PLM is capable of terminating up to 12 ports of channelized
DS3s, and mapping the 28 DS1s within each DS3 as individual VT1.5s for transport around a SONET
ring.
