Solution
Check the neighboring
node/transport/regenerator for SONET
Layer 1 issues (LOS, LSF).
This is a SONET Layer 1 issue with an
intermediate unit (usually transport
connection or regenerator) forwarding an
AIS.
None.
Solution
User initiated, none.
User initiated, none.

Keepalive failure—LSD.
WTR period is 10 to 360 seconds (user
configured), node will unwrap at end of
WTR. None.
