15.
NOTE:
When the 29-Type OLIU is installed, an
unexpected CP type status alarm will occur. The
inc. OC12 LOS alarm clears at both ends of the span. The
inc. VT and STS AIS alarms clear downstream.
Install a 29-Type OLIU into MAIN-1 OLIU slot and reconnect
optical fibers. Wait until the blinking FAULT LED goes off
before continuing.
16. At the next Node (Node 2 in this example), switch STS-1 and/or
VT1.5 path from MAIN-2 to MAIN-1 with the
switch-path-sts1: and/or switch-path-vt1: commands.
17. Remote login to Node 3 and switch STS-1 and/or VT1.5 path from
MAIN-1 to MAIN-2 with the switch-path-sts1: and/or
switch-path-vt1: commands.
18. Use the
rtrv-sync;
command to verify that MAIN-2 is the
active circuit pack, and active reference/line.
19. Use the
switch-sync:s=src;
and
switch-sync:s=circuitpack;
to force timing to MAIN-2.
20.
NOTE:
A CP removed alarm will occur and an inc. OC3 LOS
alarm will occur at the connecting Node when the MAIN-2
OLIU is removed from this Node. Other nodes will receive
inc. VT and STS AIS alarms.
At Node 2, remove optical fibers and lift the faceplate latch of
MAIN-2 OLIU for next span being established, then remove
MAIN-2 OLIU.
