Hello, Over the past several weeks, we have been having an intermittant problem with our deployment of a TDM400P card (4 fxo). ?We have tried many things, and the problem still re-occurs. The Problem: Occasionally (every 48 hours), the TDM400p card will stop answering incoming calls on ALL fxo ports. ?Attempts to send outbound calls on any Zap channel will result in hearing a loud 'static' noise on the line. On one occasion the problem actually occurred while someone was on an active call with the PSTN. ?25 minutes into the call, this loud static noise occurred, and the call was dropped. Debug log files show nothing unusual. It's obvious that * is unaware that there is any problem with the card. The Environment: - TDM400p card (REV F), with 4 FXO modules - Server power is filtered through a UPS and a noise canceling powerbar - RHEL with 2.4.2 kernel - Zaptel from 2004.06.29 cvs - Asterisk from 2004.06.29 cvs More Details: - No interrupts are being shared - We have tried replacing the server with a completely new server (same tdm card) - Reloading Asterisk will NOT correct the problem - Reloading the wcfxs module WILL temporarily correct the problem I've had conversations with others that have had this exact same problem. Some resolved the issue by changing PCI slots, changing computers, or filtering power. Others find that a nightly restart of the server helps. And at least one other, is just like me and struggling to find a solution ;-) Digium support has yet to find a solution. I'm really out of ideas here - I'll take any bone you can throw me. Thanks -- .................................. Ryan Courtnage Coalescent Systems Inc 403.244.8089 www.voxbox.ca

Are you sure the noise is coming from the FXO ports? Are you using SIP phones, or ZAP?

Is it ever during ALIT times (usually very early morning)? Have you tried calling the telco to see if it could be their problem? How far away from the CO/mux are you? Have you tried a new/different card? If you didn't want to fork out the cash for a new one, you could try a X100P/knockoff* on one of the lines to see if that fixes the problem... if so you can deduce a bad card. Nick *I usually don't recommend the knockoffs, but for a day of testing $10 sure beats $100... everybody else should support Digium! :-)

We have tried many things, and the > problem still re-occurs.We have a nearly identical problem with a TDM400P with 1FXO and 3FXS ports. In this setup only *one* of the ports is connected>: a FXS port is connected to an analog phone.> Occasionally (every 48 hours), the TDM400p card will stop answering incoming > calls on ALL fxo ports.

Rebooting the server corrects the problem. I haven't yet tried stopping and starting Asterisk and the drivers. Because of the similarity of the symptoms and the fact that this card isn't connected to the PSTN or anything, I suspect a driver problem or card design problem. -- Robert Withrow, BWithrow@NortelNetworks.com, +1 978 288 8256, ESN 248
