!
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 DS3/DS3PM
circuit packs for DS3 service. It also assumes that STS1E
circuit packs have been installed if the other end is an EC-1
interface. If it has not been installed, refer to System
Turnup/Circuit Order: IXL-001 for procedures to add a new
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 DS3 group being added.
4.
Set line build out (LBO) option jumpers and install DS3/DS3PM
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.
