IGX UFMU HSSI to 7204 HSSI Interface Reset

Have a strange anamoly...IGX 8430 9.1.15/UFMU HSSI BACKCARD in 2 port mode at 16Mbps connects via direct cable to 7204 12.0(3c) HSSI...IGX also has additional UFMU with 8port V.35 back with T1 remotes coming in...lately started to get interface resets which show up on the Stratacom UFMU/HSSI card a communication failure and then knocks down all of the frame-relay pvcs on the router...replaced router and cards which are only a FE card and the HSSI, all other slots open...replace the entire Stratacom unit with new cards...problem still re-appears....only have 7 of the 12 V.35 ports in use and a total of approximately 20 connections built between the UFMU V.35 TO HSSI.....has anyone out there run into this poblem??


Re: IGX UFMU HSSI to 7204 HSSI Interface Reset

This might not be it, but I just worked on an ATM DS3 issue where interface resets

were seen and it was due to line buildout between a BPX and 7200. Basically the DB levels were to high and the recieve side was being over-driven. If you have test equipment you might want to , if you've not done so, check your signal levels to make sure they are within tolerances. Attenuators, if line to short might help if this is the issue.

Hope this helps,
