14.4.56 FE-LOS
•
Not Alarmed (NA) (Condition)
The far end LOS (FE-LOS) condition means a far-end node reports a DS-3 LOS. The prefix FE in an
alarm/condition message means that the main alarm is occurring at the far-end node, and not at the node
reporting this FE-LOS alarm. Troubleshoot the FE alarm by troubleshooting the main alarm at its source.
Both alarm/conditions clear when the main alarm clears.
Procedure: Clear the FE-LOS Condition on the XTC28-3 Card in C-bit Format
Step 1
To troubleshoot the FE alarm/condition, determine which node and card link directly to the card
reporting the FE alarm.
Step 2
Login to the node that links directly to the card reporting the FE alarm.
Step 3
Clear the main alarm.
14.4.57 FEPRLF
•
Minor, Non-Service-Affecting
The far end protection line failure (FEPRLF) alarm means that there was an APS switching channel
failure of signal on the protect card coming into the node.
Note
The FEPRLF alarm only occurs on the ONS 15327 when 1+1 bidirectional protection is used on optical
cards in a 1+1 configuration.
Procedure: Clear the FEPRLF Alarm on a Four-Fiber BLSR
Step 1
To troubleshoot the FE alarm, determine which node and card link directly to the card reporting the FE
alarm.
Step 2
Login to the node that links directly to the card reporting the FE alarm.
Step 3
Look up and troubleshoot the main alarm.
