Here is my system: POWER SUPPLY 450W ALLIED ATX450P4 R(41) MB NFORCE2 A7N8X DELUXE ASUS RTL(Standard) CPU AMD|2500/333 ATHLON XP BARTON R(Standard) DDRAM 256M|DDR333 PC-2700 -K %(Standard) HD 40GB|WD 7200RPM 8MB WD400JB%(70) VGA ASUS|V8170MAGICII/T 64M MX440SE(58) CD ROM 56X|AOPEN CD-956 RTL(22) Besides the above parts, i have 2 X100P FXO PCI cards, and 1 TDM40B I bought 2 phones from radio shack: 1: "trim phone with caller id" this is a standard phone with caller id, no wall plug - $14 2: 2.4Ghz radioshack single line cordless phone with caller id (looks similar to uniden phones) The system has a minimal server install of RH 9 with all patches There seems to be a problem with the (not "my") TDM400P hardware. Here is the origional problem: Sometimes there is a clean dialtone. Sometimes there is a loud crackling sound over the dialtone. Eventually, over the course of 2-4 hook transitions, the TDM40B fails consistantly with the message: "Power alarm on module N, resetting!" where N is the number of the module that the phone is plugged into. This usually, or always happens on the transition from on-hook to off-hook. Once this happens i lose dialtone on all of the modules, and it doesn't come back until the drivers are reloaded, * restarted Battery is lost sporatically, but usually comes back with no dialtone Here is what i looked at so far: First i looked over the software setup; drivers, config files, and linux I tried both loop start and kewl start signalling. Results were more or less the same with both. I called Digium. They are very friendly, and they worked with me to try to find the problem. The wcfxs driver was modified so that it now doesn't need to be reloaded when the module resets. The problem of the card reseting was not solved here, and the operation of the card is more or less the same. If a good dialtone is found (which does happen occasionally) it won't last more than a few hook transisitons. They suggested i try the cards in another machine. The other machine is a P2 MMX with what i think is an asus AB-BX6 motherboard, 512MB ram, fresh RH 9 installation. The motherboard has both PCI and ISA, and AGP busses. I pulled some cards out of the older machine and installed the 2 X100P's and the TDM400P into this machine. After installing asterisk, and the drivers I found that the FXS driver was not loading. I looked at the box and the 4 green LED's on the card were not lit. I double checked the power connector on the TDM400P, and it was connected to the same power cable as the HD. I doubt there is a problem in this PC as i have been using it for years, and quite a bit lately. At the request of Digium tech support i ran 'lspci' and the TDM400P card did not show in the list of cards, while the 2 X100P's were represented. At this point I thought that i had gotten a bad TDM400P. Digium agree'd and sent me a new one. I just put the new one into my origional system and i have the same intermittent operation. The error message is a little different since the driver was edited, but the problem is the same. The card operates exactly the same as the one i just sent back to Digium. It is unusable. The origional system is about 2 weeks old (i bought it for this project), and I have no reason to beleive that there is something wrong with it. I've tested the voltage at the TDM card's rear power plug, and both the 12V and 5V busses are there. Could this a systemic problem with all new TDM400P cards??? Could the driver be reseting the tdm400P's modules erroneously??? (my fingers are crossed) Has anyone else who has used this card with analog phones had the same problem?

A phone connected to the TDM400P (only one port) will hear a loud crackling over the dialtone. The reverse (microphone) audio is even worse -- almost totally drowned out by noise. I can post a recorded sample if it would be helpful, but it sounds like crispy white noise. Asterisk can not decode the touch-tones, of course. Stranger yet, the card seems to have gotten worse over the last four days. When it was first installed, it was fine. Then a little static, then a lot of static, and now it's useless. Temperatures have been stable, and no other hardware changes explain it. I have tried connecting an 8-pin RJ45 cable with RJ11 adapter, with no improvement.> "Power alarm on module N, resetting!"I do not get this error. I have only one phone attached. I've tried multiple known-good phones. I have the power connector attached (since it would not work without it). The machine (Intel P-III) has been stable for over two years and has four other PCI cards in it. The X101P Wildcard FXO works fine. I'm looking for clues as well, especially regarding the degenerate behavior. -Steve
Here is some more information about my problem: With 2 phones plugged into the 4 port FXS card, here is a situation I have witnessed: I have a clean dialtone one phone. The instant the other phone goes from on-hook to off-hook, the clean dialtone on the first line turns into a loud crackling sound with a faint dialtone in the background. I have also noticed that if I start the computer from power off with both phones plugged in, that seems to have more of a chance of normal operation (for a few minutes max), than if I plug the phones in after the machine has started up. There is also an additional problem now of the driver occasionally flooding my screen with kernel error messages. These are different error messages than the original "Power alarm on module N, resetting!", (sorry I don't have the new error text available at this location). Once it starts the flooding does not stop until I unload the driver. Anyway, this problems seems to have less to do with * than it does Digium. Can anyone tell me if they have had any problems using the Digium X100P cards and the Cisco ATA186 together with asterisk??

The only codec that is compatable with Asterisk without additional non-free codecs is the ULAW or ALAW codec. See the URL in my .sig for sample sip.conf and the various other configs, including the ATA-186 config. -- Sample configs and more: http://www.fnords.org/~eric/asterisk/ BTEL Consulting +1-850-484-4535 x2111 (Pensacola) +1-504-595-3916 x2111 (New Orleans) +1-877-677-9643 x2111 (Toll Free)
>So, do you have the P/S 4-way connector plugged into the TDM400P ?>Regards...MartinYes, and I've tested the voltage to the card. Both the 12V and 5V supplies are OK to the card. -Sean
I noticed a similar thing with my new TDM400P. I noticed I was getting the line noise when the hard drive was running. I had the drive on the power cable first then the TDM400P card. I moved the hard drive to a different power connector and it seemed to fix the problem. May have just been a coincidence, but you may want to try that. -------------- next part -------------- An HTML attachment was scrubbed...
