.
NOTE:
This procedure assumes that the DDM-2000 is in service
and that a new group is being equipped with TMUX circuit
packs for DS3-to-DS1 service. It also assumes that DS1 or
STS1E circuit packs have been installed if the other end is
an DS1 or EC-1 interface. If it has not been installed, refer to
System Turnup/Circuit Order: IXL-001 for procedures to
add a new DS1 or STS1E group.
NOTE:
If the DDM-2000 fails to respond in the indicated manner,
refer to Trouble Clearing: IXL-001.
Determine which FUNCTION UNITS group (A, B, or C) is being
equipped.
