1 edit | [HELP] 3640 MLPPP 3 T1's bouncing Have been going back and forth with ATT for about a week now. They thought the problem with 3 of our 4 t1's bouncing and taking errors was a smart jack in another office. Well after a few days the problem is still there. 3 of the T1's are still taking errors. One of the T1's however is rock solid, no errors. When I plug this 1 t1 that has no errors in any of the other csu's it follows that circuit, so unless I'm wrong, this should help prove it's not my equipment correct? Just today I replaced the WIC's and the same problem is still there. Granted, the errors aren't all that high at time, but sometimes when they do get higher, the 3 t1's taking errors will bounce up and down for a minute or two. Any advice what to do next? I can call att and they will dispatch someone out to check it, but they said if it ends up being something on my equipment, that it will be billed at a very pricey rate.... | |

Would AT&T know when or if the circuit is bouncing? | |

| Re: [HELP] 3640 MLPPP 3 T1's bouncing Yes and Yes, I just don't have a managed router with them. They have been seeing it bounce also, and alot of times auto generated tickets have been popping up alot this week with them. I'm fairly certain it's not my router, but would like some other people's take on the situation. | |

| Re: [HELP] 3640 MLPPP 3 T1's bouncing Any telco (including AT&T) always say "no issue" when they don't see it right in front of their eyes. Probably there was no issue seen or happened during the after-hour intrusive testing, hence they said "no issue"  | |

1 edit | You already tried different WIC's, but have you tried a different cable from the smartjack to your WIC's? It could be an issue between the smartjack and the WIC.
Unfortunatly I think the only way to determine if its something wrong with the smartjack is to go ahead, and have AT&T dispatch a field tech with a t-berd to test the smartjack port.
You said that they bounce up and down so are all 4 DS1's in a MLPPP circuit? In thats the case you should be able to try and schedule the testing around the time you experiance the problem.
Weather can sometimes effect things too. Remote box/repeater overheating or getting wet/humid and causing problems.
