Figure 3-38 DS3 TMUX M13 Multiplexing Flow Diagram
A TMUX card at the CO relieves the network provider from installing and managing external M13 muxes
at the remote sites. DS-1s transported from remote sites can be M13 muxed by the CO based TMUX card
before handing off to the switch. This solution simplifies the access network and improves overall network
reliability.
When coupled with the TE-2020's VT grooming capabilities the DS3 TMUX PLM can deliver DS1 ser-
vices to multiple locations on the ring while still providing a single DS3 aggregate handoff to network
switches at the hub site. Similarly, remote DS1s, even if originating from a single location, may be broken
out for handoff to switches over multiple DS3 interfaces. Normally this could not be achieved using
remote M13 muxes without the use of an external 3/1 DCS at the CO.

In addition to the TMUX mode, any port on the TMUX card may be configured as a standard (non-chan-
nelized) DS3/EC1 port.
Portless TMUX Mode
In the Portless TMUX mode each TE-2020 TMUX PLM is capable of terminating up to 6 STS-1s carrying
remotely mapped DS3 ports, breaking out the DS1s and mapping the 28 DS1s from each DS3 back into an
