2. Notify maintenance center that alarms will be generated.
3. Use the set-fecom: command to set the User Side/Network
Side parameters.
4.
NOTE:
It may be helpful to make a sketch of the network to visualize
the cross-connections required.
Use rtrv-map-network: and rtrv-map-neighbor:
commands to determine systems (sites) in the network and how
they are connected to each other.
5. From office records or by using the rtrv-crs-vt1:all
command at any site, determine the existing cross-connections.
6.
!
CAUTION:
Critical or Major alarms will be generated if pass-through
cross-connections are not made on the new shelf before
splicing it into the network.
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.
