Nor could I, but we foound a bad crimp on the cable from the CPE to the PBX. Is yours also a T1/PRI interface?

ok guys what I found here was I kept geting alarm 75 on my Bri links and found alarm 75 was when the link went down the system would log an alarm 75 try it un plug your Bri and see what alarm you get.

I think it would be in relation to a PRI not a BRI. Anyway I am working on a similar issue. I get alarm 75 then five minutes later I get Evt:372-00 s5 meaning that the long term threshold has been exceeded. This re-sets the DTI card and drops all calls on the PRI.

I have heard that there are issues with certain software versions of the MICS. One of the guys on Techtips.com said that if it is 6.0 with a PRI replace it. In working with AT&T the Tier 3 tech told me the same thing. After upgrading the software I am still recieving the Alarm 75 and Evt:372, but it has slowed and all the AT&T commwatch is catching now is clock slips.

Not sure if any of that is relavent but there you go, as an example!
