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 #1inanOC-3orOC-12shelf,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 or OC-12 ring node sites, make proper cross-connections.
For example in Figures 5 and 6, at Node 5, if VT1.5 channel #1, VTG #1, STS
#1fromtheMAIN 1 OLIU is to be cross-connected to FUNCTION UNITS
group A, OC-1 line #1, then the command
ent-crs-vt1:m-1-1-1,a-1-1-1:cct=twoway wouldbeusedtomake
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.
14. After all cross-connections are made, use the rtrv-alm: command to verify
no alarms are present.
15. 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.
