NOTE:
To configure the transmission path for each T1 circuit being
established, terminating (drop) cross-connections or "drop
and continue" cross-connections must be made at
terminating nodes and pass-through cross-connections
made at intermediate nodes.
NOTE:
In ring configurations, you should use the following rules in
establishing cross-connections in each ring:
1. All drop connections (including DRI, if present) from
the same STS-1 timeslot must be provisioned the
same, either all VT1.5 or STS-1.
2. If all 28 VT1.5s (DS1s) in an STS-1 are being passed
through at a node in a VT1.5 path-switched ring, then
the cross- connection may be provisioned as either a
pass-through STS-1 or VT1.5. However, if you
anticipate dropping VT1.5s from the pass-through
node in the future, you should provision the
pass-throughs as VT1.5 cross-connections.
3. On STS-1 path-switched rings, all nodes in the ring
must be provisioned as STS-1 cross-connections.
NOTE:
The following commands may be used to convert, delete,
enter, and retrieve cross-connections: dlt-crs-sts1,
dlt-crs-vt1, ent-crs-sts1, ent-crs-vt1,
rtrv-crs-sts1, and rtrv-crs-vt1. See the
"Commands and Reports" section of this manual for a
description of commands. See "Cross-Connection
Provisioning" in the "Administration and Provisioning"
section of this manual for more information on
cross-connection provisioning.
Determine the necessary cross-connections for each node from
the work order or circuit order.
