DDM-2000 OC-3 MULTIPLEXER
Add New MXRVO Group for DS1 Service
System In Service
DO ITEMS BELOW IN ORDER LISTED . . . . .FOR DETAILS, GO TO

!
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,orC) is being
equipped.
2. Use the rtrv-alm command to verify that no alarms, locks,
loops, or switches are present.
3.
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.
DLP-506At DS1 terminating end, install MXRVO circuit packs into proper
slots of FUNCTION UNITS group (A, B,orC) being equipped.
