[cisco-voip] 3845 pri AIS detected

[Robert Shearrill]

Hi

Can anyone tell me what AIS detected on my pri means.

I had and pri go down, and when i looked at sh log in the gateway, it showed

Controller-5-updown: Controller T1 0/0/0, changed state to down (AIS detected)

Can anyone tell me what AIS detected means. or where can i find a list of errors like this on cisco web site.


Thanks
