What To Do About Alarms

Some alarms will clear after the user-configured timeout has

expired. Other alarms require you to take corrective action.

• If an alarm has been cleared, no other action is required.

• If there is a loopback present (unless you are intentially

testing), remove the loopback. (Only if the loopback is from

your end. If it is from your telco, you may need to verify the

loopback with them.)

• If you have a Loss of Frame (LOF), you may have a telco or

module problem. To test, do a Repeater Loopback (RLB) to test

for LOF. If there is no LOF indicated by the test, the problem is

with the telco.

• If you have a Loss of Signal (LOS), check your router cables,

power, and ports.
