19. Use the rlgn command, if possible, or have the central maintenance center
login to a shelf where the service should be pass-through cross-connected (for
example, m-1-1-1 to c-1-1-1). Use the rtrv-crs-( ) command to determine
if the time slot identified in Step 12 is cross-connected as specified in circuit
layout or other office records. If service is cross-connected through other
maintenance subnetworks, such as dual ring interworking (DRI), look for
missing cross-connections in the other subnetworks.
20. Are there any missing cross-connects?
If YES, then continue with Step 21.
If NO, then proceed to Step 24.
21. At any shelves with missing cross-connects use ent-crs-( ) to provision
the pass-through cross-connect.
22. Use the rtrv-alm: command to see if alarms have cleared.
23. Did alarms clear?
If YES, then STOP. YOU HAVE COMPLETED THIS PROCEDURE.
If NO, then continue with Step 24.
24. Repeat this procedure from Step 19 to look for other missing
cross-connections.
