WARNING:
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(s) is being added with MXRVO circuit
packs for DS1 service. If the group is already equipped with
MXRVO circuit packs, refer to Circuit Order: NTP-006. This
procedure also assumes that STS1E circuit packs have
been installed if the other end is an EC-1 interface. If proper
circuit packs have not been installed at the EC-1 interface,
refer to System Turnup/Circuit Order: IXL-001 for
procedures to add 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.

NOTE:
If the group is to be equipped with any BBF3/BBF3B
DS1PM circuit packs, both service and protection MXRVO
circuit packs must be installed.
At DS1 terminating end, install MXRVO circuit packs into proper
slots of FUNCTION UNITS group (A, B, or C) being equipped.
