Location Description
NEND The threshold for severely errored seconds
has been crossed.
Suggested Corrective Action
1. Check the optical output level at the upstream
transmitter.
2. Check the optical receive level at the input to the local
BDL1-3R11 blade.
3. Replace the blade.
Location Description
NEND The span loss variation is above the
threshold level.
Suggested Corrective Action
1. Verify the proper threshold levels with local standards.
If needed, reset the PM threshold to correct.
2. Follow local practices to check the physical
characteristics of the existing span.
