5. Use the rtrv-eqpt: command at each node to verify that each shelf is
properly equipped for the service being established. For example, is the group
or slot being used for service at the terminating ends equipped with the proper
MXRVO and/or DS1/DS1PM circuit packs if DS1 service is being established?
6.
NOTE:
Cross-connections supporting DS3 services are STS-1
cross-connections. Cross-connections supporting DS1 services are
VT1.5 cross-connections. If STS-1 cross-connections are made at a
shelf, there is a fixed mapping of all 28 VT1.5 cross-connections to a
specific shelf group (see ent-crs-sts1 command).
NOTE:
The following commands may be used to delete, enter, and retrieve
cross-connections: dlt-crs-sts1, ent-crs-sts1, dlt-crs-vt1,
ent-crs-vt1, rtrv-crs-vt1, and rtrv-crs-sts1. See the
"Commands and Reports" section of this manual for a description of
commands.
From work order or circuit order, determine the cross-connections to be made
at each node associated with the service being established. See Figures 5
through 9 for examples.
7. Starting at one of the terminating nodes for the DS1/DS3 circuit being
established, use the rtrv-crs-( ): command at each node in the ring to
verify that the cross-connections specified on the work order or circuit order
may be made. For example, if the DS1 #3 low speed port in the DS1 circuit
pack in slot #2 of Low Speed Group A (a-2-3) is to be connected to timeslot
m-1-2-3 and the rtrv-crs-vt1 command shows that the cross-connection
is already established, you should determine from office records if this port is
already in-service before continuing with this procedure.
If cross-connections are already assigned or improperly assigned, refer trouble
to the organization responsible for facility design. Improperly assigned
cross-connections may have to be deleted using the dlt-crs-( )
commands.
