Board 1 was _really_ board 1 for 2 years ... don't think they just swaped by themselves. 
Any way ... i replaced board 1 and 3 and now it's everyting back to normal... 
thx for the help...

Re: [Asterisk-Users] Problems with TDM400P and FXO modules

[Sharon Lim]

I am sorry cause i post this questions is not related to your problem, but i am having problem detecting my TDM400P which is a TDM400P problem. I manage to installed the card with compiling with zaptel and it got 2FXS and 2FXO. 
I am having problem while reboot or restart the system. Kudzu seem to detect TDM400P network card which is Tiger Jet Network Modem /ISDN hardware removed. Is quiet confusing cause if i remove the hardware configuration is still working and something the card no circuits flow. 
I am using centos 4.2, asterisk , zaptel, libpri 1.2.2 and runnning freepbx as interface to asterisk. When i run ztcfg -v , output as below :Zaptel Configuration==
Channel map:Channel 01: FXO Kewlstart (Default) (Slaves: 01)Channel 02: FXO Kewlstart (Default) (Slaves: 02)Channel 03: FXS Kewlstart (Default) (Slaves: 03)Channel 04: FXS Kewlstart (Default) (Slaves: 04)
4 channels configured.Thanks in advance. On 5/9/06, Rich Adamson <[EMAIL PROTECTED]

Which part of the previous post did you not understand?

You wrote the entries in /etc/zaptel.conf "assuming" that what you are 
calling Board 1 really is Board 1, and its not. Its Board 3 using your 
numbering scheme.


I don't know of any way to determine exactly how three identical boards 
are numbered, so you'll have to experiment to determine which board 
holds channels 1-4, which has channels 5-8, and which has channels 9-12.


Its obvious from the error message that you posted that channel 9 and 10

in the first two positions of that board).


So, change your /etc/zaptel.conf and zapata.conf to address the empty

Hi , I have an asterix (1.2.7.1 ) box with 3 TDM400P and

The problem is that 6 modules can't be initaized and i get the folowing 
error:

such device

here = 0, tmp->channel = 9, channel = 9


In general terms, the problem seems to be related to exactly which TDM 
card is considered first, second, and third. The order in which they are 
used is not necessarily related to which pci slot they are located in. 
(Just went through the same issue yesterday.)


Since channel 9 is the one causing the issue, it is the TDM card with 
only two fxo modules on it. The other two cards are channels 1-4 and 5-8.



ztcfg output is:

Zaptel Configuration

Channel map:

Channel 03: FXS Kewlstart (Default) (Slaves: 03)
Channel 04: FXS Kewlstart (Default) (Slaves: 04)
Channel 05: FXS Kewlstart (Default) (Slaves: 05)
Channel 06: FXS Kewlstart (Default) (Slaves: 06)
Channel 07: FXS Kewlstart (Default) (Slaves: 07)
Channel 08: FXS Kewlstart (Default) (Slaves: 08)
Channel 09: FXS Kewlstart (Default) (Slaves: 09)
Channel 10: FXS Kewlstart (Default) (Slaves: 10)
Channel 11: FXS Kewlstart (Default) (Slaves: 11)
Channel 12: FXS Kewlstart (Default) (Slaves: 12)

10 channels configured.


The above is only reflective of what you define in /etc/zaptel.conf. If 
those definitions are incorrect (eg, incorrect order), you will see the 
above display.  Since you already know channel 9 does not have a module 
in it, the zaptel.conf should probably read something like:


fxsks=1-8,11-12

After correcting the above, you'll need to change zapata.conf to exactly 
match the entries in zaptel.conf.

Well, if you would like another data point, my current system has:
1 x X100p
1 x TDM40b  (I think, quad FXS)
1 x TE410p  (Quad E1 card)

it never has 0% under the idle column, though it does occassionally
approach 50% (eg, 52% etc) and is a dual AMD Athlon MP CPU.

Results from zttest (while asterisk is running):
--- Results after 63 passes ---
Best: 100.00 -- Worst: 99.987793

All samples are 100% except 13 which are 99.987793

All cards are on their own IRQ (16/17 and 18)

Kernel 2.6.11 (plain linux kernel, custom compiled)

More details available on request, just let me know what you want...

Regards,
Adam

First time I compiled my own kernel I followed the instructions on
this page : http://www.voip-info.org/wiki-Asterisk+Zaptel+Installation

And this page : http://www.digitalhermit.com/linux/Kernel-Build-HOWTO.html

All this to install Zaptel on kernel 2.6

Now that I've got a distructable system, I'd like to try that.

Can you point me to some basic doc on how to do that? I'm rather
familiar with linux (about ten years worth), but have never tried to
flop kernels like that.

Thoughts?

Very good Rich, the results of that work will be very interesting.

And now for the results (thus far)
Built a new system from scratch using ECS PM800-M2 Mobo, ide 7200 rpm
drive, 2.7ghz celery, 512 meg, fedora 3 (v2.6.9-1.667, no updates).
With TDM04b installed only (new system):
 - 'vmstat 1' shows 100% cpu every 8 seconds with no significant changes
while processing a single pstn or iax call.
 - zttest shows 99.987793% consistently with no significant variation
 - wctdm using Int #11 (no sharing)
With Digium X100P installed only (new system):
 - 'vmstat 1' shows 12% cpu every 8 seconds with no significant changes
   while processing a single pstn or iax call.
 - zttest shows 99.987793% consistently with no significant variation
 - wcfxo using Int #11 (no sharing)
Conclusions:
 - the vmstat indication of 12% peak on x100p vs 100% peak on TDM04b
   suggests that each fxo module/port is being accessed by asterisk
   every 8 seconds, and not likely to be a kernel config/version issue.
 - the zttest ran exactly the same error rate regardless of the x100p
   vs TDM04b, and regardless of the significant changes in the Mobo.
   Since the x100p uses wcfxo and the TDM uses wctdm, either the same
   issue exists in both drivers (or its zaptel), or, its a Tigerjet 
   pci issue.
 - the 2.2ghz vs 2.7ghz celery processor differences had zero impact.
 - the kernel for RHv9 (2.4.20-31.9) vs Fedora3 (2.6.9-1.667) appears
   to have no significant impact on the TDM/pci throughput or
   interrupt servicing.
 - the improvement in zttest results from 99.975586% on a three year old
   mobo vs 99.987793% for the newer PM800-M2 mobo is _almost_ insignificant
   but its unknown whether the mobo, the slight cpu speed increase, or
   the kernel differences actually contributed to that slight improvement.
   (I have not tried spandsp on the new system.)
 - a modified zttest.c run on both systems to show the delays in reading
   8192 bytes from the TDM card as 23,850 microseconds lateness on
   the old mobo, and 24,000 microsecond lateness on the new system. No
   significant change resulting from the differences in mobo, pci
   structure, interrupt structure, cpu speed, quantity of ram, kernel
   differences (v2.4 vs v2.6), etc.

All of the above testing would suggest that in order to make the TDM04b
(and x100p) work reliably with things like spandsp (and probably better
echo cancellation), one or more of the following would need to be 
investigated:
 - issues with the Tigerjet pci controller on the TDM & X100p cards,
 - since asterisk code was not running when zttest was running, code
   within asterisk should not an issue.
 - with only wctdm/wcfxo/zaptel drivers loaded (no asterisk), the vmstat
   results suggest the OS is still doing something with the cards that
   is not being done when used on FreeBSD. Whatever that is, could "that"
   be the reason for the 24,000 microsecond lateness? (Probably not
   likely since that peak traffic occurs every 8 seconds, and that
   peak does not impact the 24,000 microsecond lateness measured every
   second.) Could there be code in wctdm/tcfxo/zaptel that is instigating
   the unusual vmstat results? Are the vmstat results a smokescreen?
 - is there anything unusual about the zap/pseudo OS interface that would
   impact these measurements (eg, is this the correct way to measure it)?
 
Any suggestions on the above would be greatly appreciated!!!

Hello Rich,
You're doing outstanding research.
As I recall, I've seen CPU spikes every four seconds, and I believe it 
was on an Intel mobo with a P4 w/ hyperthreading.

El wrongo kimster, they're described in this post to the asterisk-bsd list:

http://lists.digium.com/pipermail/asterisk-bsd/2005-March/000719.html

The patches are in this post:

Very good Rich, the results of that work will be very interesting.

Realtime scheduling modifications for Linux and FreeBSD are
discussed on Mantis at:

http://bugs.digium.com/bug_view_page.php?bug_id=0003203

Should you decide to evaluate Asterisk on FreeBSD, you might want to
take a look at Staffan Ulfberg's excelllent contribution on the above site,
with links to patches near the bottom of the page.

The system described in my recent post was built from * CVS Head of
4-22-05 with these patches applied, with the exception of the changes
which cause Asterisk to lower it's priority to normal after forking.

The zaptel drivers for FreeBSD are from 4-26-05, downloaded
from the Subversion repostory as described at:

http://www.voip-info.org/wiki-FreeBSD+zaptel

Patches to the zaptel drivers are described on the Mantis link above.

One of the easiest ways to determine whether any disk drive is
impacting audio quality is evaluate the system in a no-load
environment. (eg, process a single call with nothing else going
on in the system including no swapping.)

Then compare the audio to the same test repeated while generating
large amounts of disk activity. (If I recall, 'hdparm -t' generates
lots of disk activity.)

Tests conducted this weekend (but incomplete right now) suggest the
OS is doing something that impacts the TDM card specifically. Not
sure what that is as yet, but likely to have something to do with
the pci bus and/or interrupt handling.

Seems the TDM card implementation (at least in the RHv9 distro) is
not being serviced in reasonable timeframes. I modified the zttest.c
app to display the length of time required to receive 8192 bytes
of data from the card. In all cases tested thus far, the 8192 bytes
are received in about 1.021000 seconds (21000 microseconds to late).
That would suggest the data arriving from a TDM card will miss a
frame of data roughly every ten frames. That has a serious impact
on trying to run things like spandsp, but less of an impact on pure
audio.

The tests on this single system indicate that playing with the 
pci latency values had zero impact on the TDM timing. Also, suggestions
involving 'udma2' on the drive had zero impact. That only confirms
that if there isn't any disk activity, those parameters would have
no audio impact.

To help identify the source of the delays, I built a new system this
weekend from scratch. When that is complete, I'll use it to compare
the differences in motherboards, OS distro's, and maybe kernel versions.

There have been some references recently regarding disk drive types
relating to tdm400 noise problems.

Has anyone established there is a correlation between drive hardware
and noise?

If this is the case, it may be indicative of marginal interrupt timng
performance
on that hardware.

FWIW the system described earlier has a single sata drive attached to
the Intel 925XCV mb on-board controller, from dmesg:

atapci1: 

The drive is a Seagate ST3250823:

ad4: 238475MB

That's interesting; so that can potentially narrow the problematic code down 
to any bits specific to Linux and not BSD.  This is very helpful!

RE: RE: [Asterisk-Users] Problems with TDM400P card

[Rich Adamson]

The way that zttest is written makes it a little difficult to
interpret, but it essentially means that zttest tried to read
8192 bytes from the TDM card, and it took more then 1 second to
do it (the objective is exactly 1.0 seconds, or 100%).
The 99.987 numbers says it took something like 1.02 seconds
to read the 8192 bytes instead. Because it took about 21,
microseconds too long, frame slips are going to be happening
approximately every 10 seconds. (That's why spandsp doesn't work
right.)
I'm not sure (as yet) what the source of the delays are, but that's
what some of us are trying to figure out.

What OS distro are you using?

Good enough and what do I need to check in order to make 100%? What does the
test actually measure?

Kim, that is helpful. I'm not a FreeBSD user, but does it have a
vmstat utility?

If so, what do see if you run 'vmstat 1' and let it run for about
twenty seconds?  Do you see the cpu utilization going to about
100% every five or six seconds?

Since there appear to be several combinations of hardware and operating system
which don't work well, here is a combination which appears to work fairly well:

Intel 925XCV mb

P-4 560 (3.6 gHz)

wcfxs0: 

FreeBSD 5.4-STABLE

zttest -v

Re: [Asterisk-Users] Problems with TDM400P card

[John Novack]

I too wish I had a solution.
What I REALLY wish is that Digium would acknowledge that there is a 
whole bunch of problems, firstly with the card and MANY motherboards, 
then with reported problems some have with the FXO, either card or 
drivers? and FXS problems as well, again with the card and drivers.
Support is no support.
My ( and some others ) peculiar requirements make the use of many other 
devices difficult at best, and perhaps Digium wouldn't solve those, but 
this business of many having to go through a stable of motherboards to 
find one that works really makes it difficult to suggest using this card 
to others.

99.975 and as a result not being able eliminate an intermitent but consistent

Which card do you recommend using instead of the tdm400p?

The above suggests the hisax driver is loaded for that card. According
to what I see in man pages; that driver has something to do with isdn.
I'd have to guess that because that driver is loaded, the zaptel
drivers can't load.

Sounds like another response you already received somewhat addresses
the problem.

Could you post the contents of dmesg that are relavant when you load the
modules?? Just want to make sure that things are actually loading in the
order you have your zapatel.conf set for. It sounds like the cards are
not loading in the same order you have the channels configed for.

What does zttool indicate?

Have you tried moving the cards around in different slots?

Any shared interrupt issues?

Try loading wctdm before wcfxo.

Try removing the x100p's and loading the TDM card only. Any issues?

Why do you configure 6 channels if you only have 4 FXS? Try

The 2 100p cards load perfectly but the TDM is not. 

Any ideas?

Echo is miserable to try to fix.  Newer zaptel CVS checkouts have a tool
called "zttest"  What are the results of running zttest?  Unbalanced
lines can cause echo, both IRQ sharing, IDE DMA, framebuffer, and
graphics (as well as crappy motherboards) can introduce latency on the
PCI bus and cause echo.

This is not a general problem.  It sounds like you are not using group=
in your zapata.conf to put the TDM ports into a hunt group.

Sounds like something isn't providing far end disconnect supervision.

You don't have Caller*ID on your lines, but Asterisk is configured to
use (and waiting for) Caller*ID.  See the usecallerid= and callerid=
options.

RE: [Asterisk-Users] problems with TDM400P

[David J Carter]

Wim,

If ya don't need callerid then add the patch at
http://www.nodomain.org/asterisk to zaptel and asterisk directories.
I did this for UK callerid and the phone now rings on the first ring of the
CO.
Bit of a bodge but it works.

Subject: [Asterisk-Users] problems with TDM400P


Hi,

We have two of these 4 port FXO cards.

However, we are having some problems with incoming/outgoing calls.

The latest version of Asterisk/zaptel from CVS is being used. Voicemail,
internal SIP <-> SIP calls between Pingtel xpressa hard phones work
terrific, echotest is fine, and so on.

The zaptel and wcfxs modules load fine, and show all 8 FXO interfaces in
dmesg:

-
Zapata Telephony Interface Registered on major 196
Freshmaker version: 63
Freshmaker passed register test
Module 0: Installed -- AUTO FXO
Module 1: Installed -- AUTO FXO
Module 2: Installed -- AUTO FXO
Module 3: Installed -- AUTO FXO
Found a Wildcard TDM: Wildcard TDM400P REV E/F (4 modules)
Freshmaker version: 63

Registered tone zone 0 (United States / North America)

Following problems have been observed, and are preventing us from
dumping our existing Nortel Merdian PBX:

1. echo at beginning of call for several seconds, even with various
combinations of echocancel and echotraining in zapata.conf

2. even though multiple incoming lines are connected, only the first ZAP
channel is picking up. So if
one line is in use, nobody else can call in even though there are other
lines free. When in debug mode (-gcvvv) nothing is showing up that
there's another call coming in.

3. channels don't always hang up properly - HookState shows as offhook
for quite some time.

4. Asterisk Zap channels don't see an incoming call until 2 rings after
the existing Nortel PBX sees it. Both people calling in and people
answering don't like that.

I've gone through whatever documentation and mailing list archives, but
haven't been able to find working solutions. Have tried various
combinations in zaptel.conf and zapta.conf but no luck yet :-(

Ideas anyone?

Thanks,

Wim

Hi,

I had ordered a TDM40B and developers kit a few months ago.  I have

When placing a call it sounds like a very bad cordless phone - lots of
hiss / static in the background.  This even happens with the dialtone,
though it is much worse one the call is connected.  This does not occur
when the phone is directly connected to the line.  I have also tried a
bunch of different phones.  I tried messing with txgain and rxgain with
no success.

Call Digium support.  The current batch of TDMXX cards had a problem 
with the capacitors that causes the buzz when used in certain computers.

They are engineering a fix; it's supposed to be ready in the next few weeks.

The Digium cards seem to be very sensitive to sharing IRQs.  Try to make
sure the TDM40B is not sharing an interupt with any other devices in the
system.  That may or may not be your problem.
