Quick synopsys: T1 PRI's (10) We changed nothing on our end and have checked everything 100 times. Started to get fast busys radomly throughout hunt. Only thing that the DSP console is reporting is Call Block Failure Count is increasing incrementally. We have some Quads and you can see the light flash yellow for 1/5 of a second then they go dark. This indicates the calls are hitting our TC unit, but dump. Then a call will come in on the same modem and will connect. There is no rhyme or reason to it and its driving us nuts. We suspect that its the Telco, but they claim "nothings changed". PRI's are not erroring either. We've tried everything looking for some input. Thanks! Steve Hadow GTI
Hi Steve: Have had exactly the same problem, very very frustrating. Had the same thoughts as you about it being a Telco issue. Our usage is fairly light but we had maybe 10 occurrences over a period of 4 months, plenty of midnight and Sunday trips in to power cycle the TC. The final time the problem occurred I just happened to have my notebook and fired up TCM... noticed that one of the quads was yellowed-out so I had someone pull the quad and the problem was gone just like that. The quad seems to work fine 99% of the time and the occurences didn't seem to correspond with calls coming into that particular card... doesn't make any sense, but replaced that quad about 6 months ago and have not had a problem since. Only thing I can think is that it was flaking out and throwing garbage out onto the bus. If this is happening frequently enough for you, I'd say maybe just start pulling quads one at a time and see if the problem goes away. Your mileage may vary but the symptoms sound just a little too similar :-) Cheers,
Mike <<<<<

Same here.. I had a quad that did not yellow out... but quit taking calls.. and it periodically hosed up the chassis. Once I pulled the card.. and put another one in, the chassis stablized. It was easy to see which card was not accepting calls during prime time. It was the only card that never had connections. It looked okay.. optically.. and via TCM. Cheers, -Tom

Is your ARC logging somewhere? If so, see if there's anything about channels going inactive.

Had some similar behaviour a while ago, but it wasn't the telco. Had to boot a few of the DSPs to clear it up. But the problem was first seen in the arc logs... DSPs had probably been up for about a year and a half at the time. Charles
Thanks!
