Before beginning this procedure, verify ring integrity and path
protection switching function. At the start node, remove the
receive (IN) fiber from ONE of the MAIN OLIUs. Verify no critical
(CR) alarms are present. Reconnect the fiber and wait until
alarms clear. Repeat this step on the other MAIN OLIU.
3.
Notify maintenance center that alarms will be generated.
4.
Use rtrv-map-network: and rtrv-map-neighbor:

Sbyte sync messages. Use set-sync:auto=enabled
command to enable Sync auto-reconfiguration.
7.
At the starting Node 1, switch STS-1 and/or VT1.5 path from
MAIN 2(P) to MAIN 1 with the switch-path-sts1: and/or
switch-path-vt1: commands.
8.
Use the switch-sync: command to force line timing from MAIN
1.
9.
Remote login to Node 2 and switch STS-1 and/or VT1.5 path from
MAIN 1 to MAIN 2(P) with the switch-path-sts1: and/or
switch-path-vt1: commands.
