NOTE:
The following commands may be used to delete, enter, and retrieve
cross-connections: dlt-crs-vt1, ent-crs-sts1, ent-crs-vt1,
ent-crs-sts1, and rtrv-crs-vt1. and rtrv-crs-sts1.Seethe
Commands and Reports section of this manual for a description of
commands.
From work order or circuit order, determine the cross-connections (STS-1 or
VT1.5) to be made at each node associated with the kind of service being
established.
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/DS1PM
circuit pack in slot #2ofLOW 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.
8.
NOTE:
Channel state provisioning provides IS, AUTO, and NMON states for VT
and STS channels similar to the port states for DS1 and DS3 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: or
ent-crs-sts1: command to provision pass-through connections. [For
example, to make the DS1 pass-through cross-connection for channel
m-1-2-3, use the ent-crs-vt1:m-1-2-3,m-1-2-3:cct=twoway
command. To make pass-through cross-connections for STS-1 #1, use the
ent-crs-sts1:m-1,m-1:cct=twoway command.]
