, as necessary, to
correct the provisioning.

7.
NOTE:
If the service is STS1 cross-connected at either terminating shelf, both
terminating shelves must be properly 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-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.

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.
10. At any shelves with missing cross-connects use the
ent-crs-sts1:
command to provision the pass-through cross-connect (for example, m-1 to
c-1).
