[Asterisk-Users] PowerEdge 17500 with TDM400P - 4 FXO -- NMI, loud noise when dialing out
Hello All,
Please let me know if you have any comments or suggestions how to
resolve the following situation. My configuration is:
- Dell PowerEdge 1750 (standard), one CPU Xeon 3.0GHz
- TDM400P with 4 FXO, connected to 4 regular phone lines (PSTN)
- Asterisk 1.0.0 from cvs
- Zaptel and Zapata latest from cvs
- Debian 3.0 Woodoo / compiled kernel 2.4.27
Initially Asterisk works fine for a few hours, hard and soft phones are
able to dial out and receive calls from outside. In about 6-8 hours,
when I would try to dial out from any extension through Zap/1 ... Zap/4
(I have group #1 defined) I would hear continuous loud noise for 20
seconds - then silence. Call stays connected but apparently TDM400P is
not even picks up the line to dial. No sounds could be heard after that.
Repeat dials for any number of times - same thing.
What would fix this: either restart of the whole server or shutdown
asterisk, then rmmod wctdm; rmmod zaptel; modprobe wctdm. Though, in a
few hours after modules are restarted I have the same situation - loud
noise on dial out and no rings detected on inbound calls.
BTW, when on wctdm module load NMI would always occur, though the server
and card works fine after that:
Module 0: Installed -- AUTO FXO (FCC mode)
Uhhuh. NMI received. Dazed and confused, but trying to continue
You probably have a hardware problem with your RAM chips
Module 1: Installed -- AUTO FXO (FCC mode)
Module 2: Installed -- AUTO FXO (FCC mode)
Module 3: Installed -- AUTO FXO (FCC mode)
Found a Wildcard TDM: Wildcard TDM400P REV E/F (4 modules)
Registered tone zone 0 (United States / North America)
Registered tone zone 0 (United States / North America)
Here is some more information about the server:
# cat /proc/interrupts

2: 0 0 XT-PIC cascade

So it is not interrupts problem. Tried to move Digium card in a
different PCI slot (#2 now) and changing IRQ in Bios, loaded the kernel
with pci=noacpi, and nothing would help.

Please help! I would appreciate any comments or suggestions. zaptel.conf
and zapata.conf are standard taken from samples on voip-info.org for
card with 4 FXOs.
Sincerely,

Guys, If anybody interested, removing USB support from Debian kernel (2.4.27) solved the problem. Thank you for your help.

You are mixing them. Get one or the other. Also make sure your Dell has the latest firmware installed for all components they offer newer firmware for. Solved some funky problems I dealt with a while back. If you get any NMI errors, BIOS memory count that's off and really weird behavior, take out the memory modules and reseat them properly. Same applies to the CPU. Might as well do any cards while you are at it. And if you are really suspicious, check the seating of the cables too. Reseating the CPU and memory modules solved all our remaining problems. I will refrain from making obvious comments about Dell's quality control :) Patrick
