9. Starting at one of the terminating nodes for the DS1 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 #1 low speed port in the DS1 circuit pack in slot #1 of
LOW SPEED group A (a-1-1) is to be connected to timeslot m-1-1-1 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-( )
commands.
10.
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 pass-through nodes in the network, use the
ent-crs-vt1: or ent-crs-sts1: command to provision pass-through
connections. [For example, 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. To make
pass-through cross-connections for STS-1 #1 in an OC-3 shelf, use the
ent-crs-sts1:m-1,m-1:cct=twoway command.]
11. At both terminating (drop) nodes of the circuit being established, use the
ent-crs-vt1: command to make the terminating cross-connections (for
example, Node 1 and FiberReach node in Figure 5,
ent-crs-vt1:m-1-1-1,a-1-1:cct=twoway)
12. At the host OC-3 ring node sites, make proper cross-connections. For
example, in Figure 5, at Node 5, if VT1.5 channel #1, VTG #1, STS #1 from the
MAIN 1 OLIU is to be cross-connected to function group A, OC-1 line #1, then
the command ent-crs-vt1:m-1-1-1,a-1-1-1:cct=twoway would be
used to make the cross-connection.
13. Use the rtrv-crs-vt1: or rtrv-crs-sts1: command to verify that the
proper connections have been made. If an improper cross-connection is made,
use the dlt-crs-vt1: or dlt-crs-sts1: command to delete the
improper cross-connection and reenter the cross-connection.
