10. NOTE:
Channel state provisioning provides IS, AUTO, and NMON states for
VT/STS1 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-1-2-1 in other OC-3 shelves, use the
ent-crs-vt1:m-1-2-1,m-1-2-1:cct=twoway
command.]
11. At both terminating (drop) nodes of the circuit being established, use the
ent-crs-( )
command to make the terminating cross-connections at OC-3
or OC-12 nodes (for example at the OC-3 or OC-12 Node 2 and 3 in Figures 4
through 7,
ent-crs-vt1:m-1-2-1,b-2-1:cct=twoway
).
12. At the host FT-2000 OC-48 ring node sites, make proper cross-connections.
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.
14. At OC-3 or OC-12 terminating nodes equipped with BBG4B DS3 circuit packs,
use the
set-trace-sts1:
command to verify the proper cross-connect path
of a STS-1 cross-connected STS-1 signal.
15. After all cross-connections are made, use the
rtrv-alm:
command to verify
no alarms are present.
16. If DS3 cross-connections have been established and the terminating nodes
are equipped with BBG4 DS3 circuit packs, use
set-trace-sts1:
command to check integrity of cross-connect path.

17. If
ne-acty
,
inc. VT AIS
,
inc. STS1 AIS
,
inc. VT unequipped
, or
inc. STS1 unequipped
alarms are present, look for missing or improperly
made cross-connections. Use TAP-120 to locate missing cross-connections, if
required.
