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,andrtrv-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 to be made
at each node associated with the service being established. See Figures 5
through 17 for examples.
7. Starting at one of the terminating nodes for the DS1/DS3/T1/EC-1/TMUX/IMA
LAN 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 circuit pack in slot #2 of LOW 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:
The channel state provisioning feature provides IS, AUTO, and NMON
states for VT and STS channels similar to the channel states for DS1 and
DS3 ports. At installation, or 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 command. To make
pass-through cross-connections for STS-1 #1, use the
ent-crs-sts1:m-1,m-1 command.]
9. At the terminating (drop) nodes of the circuit being established, use the
ent-crs-vt1: or ent-crs-sts1: command to make the terminating
cross-connections (for example, ent-crs-vt1:m-1-2-3,a-2-3)or
ent-crs-sts1:m-1,a).
