NOTE:
Ring releases support only manual VT1.5 and STS-1
cross-connections. manual STS-1 and/or DS1
cross-connections have to be made at each shelf to
configure the transmission path for each DS3/DS1 circuit
being established. Either terminating (drop)
cross-connections or “drop and continue” cross-connections
are 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 delete, enter, and
retrieve STS-1 cross connections in a path protected ring
network: dlt-crs-sts1, ent-crs-sts1, and
rtrv-crs-sts1. See the Commands and Reports section
of this User/Service Manual for a description of commands
