Chapter 1 Alarm Troubleshooting
Procedure: Clear the FE-IDLE Condition on the DS3XM-6 or DS3E Cards in C-bit Format
Step 1 To troubleshoot the FE alarm, determine which node and card link directly to the card reporting the FE
alarm. For example, an FE-AIS alarm from the DS3XM-6 card in Slot 12 of Node 1 may link to the main
AIS alarm from a DS3XM-6 card in Slot 6 of Node 2.
Step 2 Log into the node that links directly to the card reporting the FE alarm.
Step 3 Clear the main alarm.
1.3.54 FE-LOCKOUT
• Minor, Non-service affecting
FE-LOCKOUT raises whenever the Lockout Protection Span command is entered from any other node.
This alarm indicates the prevention of any ring switch requests. The alarm clears when the lock out is
removed.
Procedure: Clear the FE-LOCKOUT Alarm on a BLSR
Step 1 Display CTC network view.
Step 2 Find the node reporting the LOCKOUT-REQ.
Step 3 Log into the node reporting the LOCKOUT-REQ.
Step 4 Follow the “Clear the Lockout Switch Request and the LOCKOUT-REQ Condition on an OC-N Card”
procedure on page 1-46.
1.3.55 FE-LOF
• Not Alarmed (NA) (Condition)
A far-end node reports a DS-3 loss of frame (LOF). The prefix FE in an alarm message means that the
main alarm is occurring at the far-end node, not the node reporting this FE-LOF alarm. Troubleshoot the
FE alarm by troubleshooting the main alarm at its source. Both alarms clear when the main alarm clears.
Procedure: Clear the FE-LOF Condition on the DS3XM-6 or DS-3E Cards in C-bit Format
Step 1 To troubleshoot an FE alarm, determine which node and card link directly to the card reporting the FE
alarm. For example, an FE-AIS alarm from the DS3XM-6 card in Slot 12 of Node 1 may link to the main
AIS alarm from a DS3XM-6 card in Slot 6 of Node 2.
Step 2 Log into the node that links directly to the card reporting the FE alarm.
Step 3 Look up and troubleshoot the main alarm.
