12TMUX (LNW18) cable installation

............................................................................................................................................................................................................................................................
Description
This section describes how to connect the TMUX cables to the 1665 DMX High-Capacity
shelf and route the cables out of the bay and to the TMUX terminating equipment.
Perform this procedure if TMUX cables are required for an LNW18 in a function group.
It should be noted that the cables used for 12TMUX support are DS3 cables (12 port). The
new high capacity DS3 cables will also support 12TMUX, but only in a 12 port capacity.

becomes an extension of the 1665 DMX High-Capacity shelf backplane connections.
Therefore, the IN on the 1665 DMX High-Capacity shelf backplane connects to the IN
of the DSX and the OUT of the 1665 DMX High-Capacity shelf backplane connects to
the OUT of the DSX.
TMUX cable options are listed in
(p. 1-44).
TMUX transmission connections are in
(p. 1-57). Total of four function groups fully cabled will have 48 DS3 drop capacity.
