CAUTION:
DDM-2000 circuit packs contain static sensitive components
which can be damaged by electrostatic discharge. A static
ground wrist strap must be worn when handling the circuit
packs. See electrostatic discharge considerations in Trouble
Clearing: TAD-100 .
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.
2.
Use the rtrv-alm: command to verify that no alarms, locks,
loops, or switches are present.
3.
Verify no DS1/DS1PM circuit packs are installed in slots
associated with new TMUX group being added.
4.
Set line build out (LBO) option jumpers and install TMUX circuit
packs into proper slots of FUNCTION UNITS group (A, B, or C)
being equipped.
5.
Make the appropriate connection(s) to the DS3 cross-connect
point(s) or equivalent connection point(s) for the circuit(s) being
added.
