NOTE:
In ring configurations, the following rules are used 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. Also,
provisioning now as a VT1.5 cross-connect will avoid a
hit on traffic if the STS-1 cross-connect has to be
converted to 28 VT1.5 cross-connects to drop DS1s at
a later time.
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: cnvt-crs,
dlt-crs-vt1, dlt-crs-sts1, ent-crs-vt1,
ent-crs-sts1, rtrv-crs-vt1, and rtrv-crs-sts1.
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-connections.
Use the dlt-crs-vt1: command to delete the terminating
(drop) node cross-connections for all LAN service being removed,
if required.
5. Use the dlt-crs-vt1: command to delete the pass-through
cross-connections at each nonterminating node for all LAN
service being removed, if required.
6. STOP. YOU HAVE COMPLETED THIS PROCEDURE.
