Cisco 7200 with a T3 port.

I have installed a 7200 with a T3 port. However when I connect it, I get an AIS alarm on one end and OOF alarm on the other end. What would I check regarding this error


Re: Cisco 7200 with a T3 port.

It is a frame mismatch problem, here are the explanations of each alarm:

AIS-The alarm indication signal alarm is set when the last FAS and NFAS frames have included less than 3 0s in timeslot 0 (the AIS is an all 1s signal). The AIS is normally set by transmission equipment detecting a fault.

OOF-The out of frame alarm is declared on a G.704 trunk when the frame alignment signal has not been seen for the last three occasions (covering 5 frames). It is cleared when the frame word has been seen on two consecutive occasions (3 frames). When the oof alarm is declared, the remote alarm bit is set.

So you need to match the parameters configured on your 7200 and those configured on the Service provider equipment, for example: framing, clock source, cable lenght, line code...
