Hi all, I've struggled for several days trying to get a Digium TDM04B 4-port wxfco card working on a Dell 1U PowerEdge 750 machine running Fedora Core 1. I finally got a call back from Digium who indicated that there is a fundamental conflict between the card and the PowerEdge having to do with PCI interrupts. Asterisk version is stable v1-0 12/29/04. The symptoms of the problem were as follows: 1. issue "modprobe zaptel" which immediately returns with no feedback 2. issue "modprobe wcfxo" which returns init_module: No such device Hint: isnmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters 3. issue "modprobe wcfxs" which immediately returns with no feedback, however the four lights on the card go on and then the machine locks up completely, requiring a power cycle to get it running again. After the power cycle, if I look in /var/log/messages I see a long cycle of the following messages before reboot: kernel: Dazed and confused, but trying to continue kernel: Do you have a strnage power saving mode enabled? kernel: Uhhuh, NMI received for unknown reason 20 on CPU 0 4. if I cat /proc/interrupts, I don't see any entry for a wcfxo module. In any case, I did follow the setup instructions on the Digium site (make install in /usr/src/zaptel, edit /etc/zaptel.conf, edit /etc/asterisk/zapata.conf, etc.) and we currently have a X100P wcfxo card in another machine running well so we've already had experience getting a card working. If anyone has insight into what might be wrong, please do let me know. Ultimately, if I trust the Digium support information, then this card will never work, so I'd be grateful to hear about any other PCI card that provides four or so wcfxo interfaces that might work with the PowerEdge. TIA, Michael Swan Neon Software, Inc.

Try the modprobe wcfxo then zaptel, then check your /proc/interrupts. If that doesn't work, try modprobe zaptel only. I think someone mentioned a readme in the src/zaptel directory for Fedora as well. Might look.
TDM400's use the wcfxs module to drive both FXO and FXS ports on them. I have an IBM xSeries 305 (1U P4 2.4ghz 1gb of RAM) server and I just picked up a TDM04B today, and I am getting the exact same problem. When I make calls to/from the TDM04B card I get this really really staticky sound. Calls show up however. Any resolutions to this? -Tim -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Rich Adamson Sent: Wednesday, January 05, 2005 6:54 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] TDM04B vs Dell> I've struggled for several days trying to get a Digium TDM04B 4-port > wxfco card working on a Dell 1U PowerEdge 750 machine running > Fedora Core 1.

I dug around and found my newest UpdateXpress cd from IBM and ran it on this box and updated the BIOS and my problem went away. *shrugs* -Tim -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Michael Swan Sent: Wednesday, January 05, 2005 7:35 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] TDM04B vs Dell At 06:53 PM 1/5/2005 -0600, you wrote:> > I've struggled for several days trying to get a Digium TDM04B 4-port > > wxfco card working on a Dell 1U PowerEdge 750 machine running > > Fedora Core 1.

I gave up having concluded that the problem was either: 1) the passive PCI Riser that is used in many 1U cases 2) the on-board server management ASIC (lights out managment, fan speed etc) It would be great to track this problem down.

Asterisk version is stable v1-0 12/29/04.Sorry to revive this older thread, but I thought it might be of interest to add a new data point into this. I have a Dell 750 with a T100P card in it now and it is seeing interupts just fine. Granted it is missing some from time to time on a system not even running asterisk yet. -- Steven Critchfield <critch@basesys.com>

I had the exact same issue with a Dell PowerEdge 750. I went round and round with digium over it and never got anywhere. I was talking to digium support around the same time you were or possibly a week or so after. They seemed to know nothing of the problem. I ended up sending my card back and getting a Mediatrix FXO->SIP gateway which works perfectly. -- Tracy Reed http://copilotcom.com This message is cryptographically signed for your protection.
