12. Note the Source Address of the VT AIS condition reported in the alarm and
status report (for example, m-1-1-1). Based on the circuit layout or other
office records, determine the other shelf where that time slot is supposed to be
terminated (cross-connected to a DS1 or EC-1 termination).
13. Use the rlgn command, if possible, or have the central maintenance center
login to the other terminal shelf, then use the rtrv-crs-sts1: and
rtrv-crs-vt: commands to determine if the time slot identified in Step 12 is
cross-connected as specified in circuit layout or other office records.
14. Were there incomplete or incorrect cross-connects?
If YES, then continue with Step 15.
If NO, then proceed to Step 17.

correct the provisioning.
16. Have all indications of VT AIS cleared?
If YES, then STOP. YOU HAVE COMPLETED THIS PROCEDURE.

NOTE:
If the service is STS1 cross-connected at either terminating shelf, both
terminating shelves must be equipped to terminate the entire STS1. For
example, if DS1 service is being provided, both ends must be equipped
with MXRVO circuit packs and the same number of DS1/DS1PM circuit
packs in the groups that are STS1 cross-connected.
Use the rtrv-state-eqpt: command at both shelves to verify that the
shelves are properly equipped for the service being provided. If the shelves
are not properly equipped, install circuit packs as required.
18. Have all indications of VT AIS cleared?
If YES, then STOP. YOU HAVE COMPLETED THIS PROCEDURE.
