Adam, I have found similar characteristics when the CAT 5 gives out, except that it usually reports Remote out of service. Occasionally, some of them report loos and the other roos. LOOS problems 2 modems at a time can indicate a bad DSP. Check the knowledgebase for more information on bad DSP detection. Modems usually fail in pairs.

chdev tslot span1/tslot1> display atstat

you can see that this snapshot reports timeslot 09 Local Out of Service. 30 seconds later it will be timeslot 22, then 01, then 08, and so on. anyone seen this before in production? adam _______________________________________________ USR-TC mailing list USR-TC@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/usr-tc
