Detect Signal Fail)

SONET Layer 1 signal fail

detected

Investigate Keepalive failure. Wrap

occurred.

Keepalive failure—SLOS, SLOF, LSF, or

LAIS.

Detect Wait to Restore

[WTR])

Wrap cleared, node

initiated; Wait to Restore

(WTR) state

WTR period is 10 to 360 seconds (user

configured), node will unwrap at end of

WTR. None.

Span Neighbor Signal Fail)

Neighbor node protected

due to signal fail

Investigate the signal degrade on neighbor

node.

Neighbor node protected

due to signal degrade

Investigate the signal degrade on neighbor

node.

Span Neighbor WTR)

Wrap cleared, node

initiated; Wait to Restore

state

WTR period is 0 to 1440, or never (user

configured), node will unwrap at end of

WTR. None. Setting WTR to never will

prevent the node from unwrapping.

Long Request Forced Switch)

Neighbor node Forced

Switch initiated by user;

Node wrap to protect

failed span; Secondary

problem on the short path

Investigate why the short path request was

not received.

Check other problems on the short span as

indicated on the neighbor node.
