Administration and Provisioning

5. Status and alarm conditions can be present during the provisioning
operation but will clear once the last ring cross-connection for this DS3
service is completed. If they do not, the rtrv-alm; and rtrv-crs-
sts1; commands can be used to isolate the problem (see the TOP
section of this manual [Volume II]).
6. Log in or remote log in to all the nodes and verify appropriate drop or pass-
through ring cross-connections.
7. Test both paths around the ring. Since DDM-2000 OC-12 uses non-
revertive path switching to minimize the number of hits on services, the
initial path selection is arbitrary. Use rtrv-state-path and sw-path-
sts1 commands to test both ring paths around the ring network at the drop
nodes of the new service. The sw-path-sts1 command should be limited
to the addresses that are being tested. For the example, the commands are
sw-path-sts1:mb1-1 and sw-path-sts1:mb2-1.
The rtrv-state-path and sw-path-sts1 commands use slightly
different STS-1 ring channel designations from the cross-connect
designations because these commands need to identify which of the two
paths around the ring is currently active. If the ring path and selected
STS-1 channel are being received on main B-1, the active ring channel
designation for the rtrv-state-path and sw-path-sts1 commands
will be mb1-1, where the mb1 is the path received on main B-1. If the ring
path and selected STS-1 channel are being received on main B-2, the ring
channel designation for the rtrv-state-path and the sw-path-sts1
commands will be mb2-1, where the mb2 is the path received on main B-2.
The DDM-2000 OC-12 allows a per path designation on the sw-path-
sts1 command. This assures that only the new DS3 service being
provisioned will be subject to protection switch hits. If this is not the first
DS3 service being added to the ring, it is strongly recommended that the
pulling of circuit packs or fibers to test the protection path not be done since
it would subject existing DS3 services to protection switch hits.
