5. Use the rtrv-eqpt: command at each node to verify that each shelf is
properly equipped for the service being established.
6.
NOTE:
The following commands may be used to delete, enter, and retrieve
cross-connections: dlt-crs-vt1, ent-crs-vt1,and
rtrv-crs-vt1. 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 DS1 service being established.
7. Starting at one of the terminating nodes for the DS1 circuit being established,
use the rtrv-crs-vt1: 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 #1 low speed port in the DS1 circuit pack in slot #1of
LOW SPEED GROUP A (a-1-1) is to be connected to timeslot m-2-1-1 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-vt1:
commands.
8.
NOTE:
Channel state provisioning provides IS, AUTO, and NMON states for VT
channels similar to the port states for DS1 ports. When a
cross-connection is made to a point of termination the channel is in the
AUTO state and alarming is disabled. The channel must receive a good
signal from either ring to cause the channel to transition to in-service (IS).
At all nonterminating nodes in the network, use the ent-crs-vt1: command
to provision pass-through connections. [Forexample,inFigure5,node3,to
make the DS1 pass-through cross-connection for channel m-1-1-1, use the
ent-crs-vt1:m-1-1-1,m-1-1-1:cct=twoway command.
