Hi Guys,
Our T3 controller is down and the SP has asked me what I am seeing on my
end. Below is the show controllers command on my router. Could you tell
me where the problem is based on the output below?
Router#sh controllers t3
T3 3/0 is down.
Applique type is Subrate T3
Description: Carrier_Circuit_ID
Transmitter is sending remote alarm.
You are sending a signal to the other end reporting that the signal that
you are receiving is unacceptable. This is happening because...
Receiver is getting AIS.
You are receiving all 1s from the other end.
Typically, this means that there is a problem with the equipment sending
toward you. Something upstream has lost signal and is sending an AIS
(Alarm Indication Signal) to you. You respond by sending RAI (Remote
Alarm Indicator) notifying the other end of the bad signal that you are
receiving.
