NOTE:
The craft interface terminal (CIT) rtrv-map-network: and
rtrv-map-neighbor: commands may be used to retrieve
a map of the SONET network, including a list of the systems
in the network and how they are connected. The
rtrv-crs-vt1: command may be used to retrieve VT1.5
(DS1) cross-connections within the DDM-2000 OC-3 or
OC-12 system. The rtrv-crs-sts1: command may be
used to retrieve STS-1 cross-connections within the
DDM-2000 OC-3 or OC-12 system.
Use rtrv-alm command to verify no alarms, locks, loops, or
switches are present.
2. Determine which DDM-2000 node (shelf) is being discontinued.
3. Verify that optical line loss budget will not be exceeded by
removing this node.
