Intel 537ep
Owias,
The 537 is, for the most part, a drop-in replacement for the Digium card. Please search the archive and the Wiki, as there have recently been several discussions about this exact subject.
To my knowledge that is about the only modem that works, but keep in mind it is _not_ supported. That being said, follow the instructions on Digium's site for installing the X100P and you should be

Effectively using a telco Type 102 Milliwatt Test line with ztmon itor -v to set txgain/rxgain in zapata?
I am trying to obtain optimum gain settings for a bank of analog lines
connected to a channel bank. My telco has provided a 'Type 102' test line to
use for incoming level calibration. This is functionally equivalent to app
Milliwatt(), but provides tone from the CO inwards.
Question is, how should one use this a 0dbm test source with ztmonitor? Am I
correct in understanding that a 0dbm

Calibrating both RX and TX gain?
Hello!
I'm having an echo problem with a TDM card. The TDM card is being fed by
a channel bank just 12 or so feet away. When you put an analog handset on
the line, both the RX and TX volume seem to be just fine. However, when I
use the TDM card, I have to have an rxgain of 13.5, and even then, the
audio is relatively quiet. I'm also getting echo on these lines, so I
have turned

PRI echo issues: solvable?
Hello,
After solving the other "low hanging fruit" audio issues in our Asterisk
PBX, we are left with occasional cases of severe echo which we have not
found a solution for yet.
Our system:
- Asterisk 1.2.0-beta1
- TE110P on a PRI
- TDM04 and TDM40, but these are unrelated to current echo issues
- Fedora core 3
- Echo canceller KB1
Most calls have minimal, acceptable echo levels. But

sangoma card rx/tx gain level
Hey Guys!
We had echo issue before so we replaced old PRI card with Sangoma A102D HWEC. Now my question is i set rx/txgain level 0.0 default do i need to touch this value or default is best. I have read on google and people say it should around 14844 on ztmonitor for rx/tx level same.
I just use milliwatt and test my default 0.0 rx/tx level and it come around 4600. Do you think i need to make

zaptel compilation problems with linux 2.6.19

How to 'read' ztmonitor and set gains
Being one the many people trying to track down echo 'ghosts' I ran across
this page:
http://lists.digium.com/pipermail/asterisk-users/2004-November/071301.html
suggesting ways to adjust the gain. I have a TDM400P 2x2 config with
Kewlstart lines configured. I've located a local telco milliwatt test line,
and when I call it, the gain numbers are no where near 14844. Now, this

TDMoE hangs the machine
I was trying to use TDMoE and I lasted with two problems. First of all I
can't configure the dynamic span to use CAS signalling but documentation
(by Mark) says that you can use any type of signalling (and this
includes CAS I guess).
My second problem is related that my Linux system crashes frequently
due to ztdynamic and friends. I'm using a 2.4.26 version kernel and

Will Echo problems EVER be solved, I'm scared
I came into this with my eyes wide open. I have read ABSOLUTELY EVERYTHING
there is to be found on the net about avoiding echo problems BEFORE I even
attempted to create a production system. Since lots of people are
apparently using this in production environments now I just assumed that
echo IS avoidable.
As others have recommended, I created a test system with the proposed

Stable clock with 2.6 and without Digium hardware.
Anybody sucessfully got stable 1000Hz clock without Digium harware and kernel 2.6?
We need to consult some peoples how to clock asterisk stable with exactly 1000 Hz without much kernel/drives patching/tweaking.
Some test results we made so far:
2.6 with digium card - stable 1000 Hz.
2.6 with ztdummy - uses RTC and the clock is 1024, not 1000.
2.6 with some Realtime kernel patch - provides stable

Milliwatt Test Number List
Hello:
Does anyone know of a list of milliwatt test numbers for debugging echo?
Specifically I am looking for a milliwatt test number in Canada,
preferrably in a 416 or 905 NPA exchange....different carriers would
also be nice....ie. Bell Canada, GT, Sprint (Now Rogers Telecom)
I called Rogers NOC and asked them for the milliwatt test number....they
didn't even know what it was....so I

Milliwatt Analyzer available
Hi,
some days ago we discused here the need for an analyzer
for the 1000 Hz tone, as opposite application to Milliwatt.
Here it is: Mwanalyze
http://planinternet.net/download/voip/asterisk/app_mwanalyze.c
It performs a Fourier analysis for a fixed frequency
and tells the amplitude.
The frequency is not limited to 1000 Hz, but can be passed
as argument. The periode duration must be a mulitple

Test Line
Hi,
Somewhere in the Wiki I read that the best way to adjust the rxgain and
txgain is to dial a "type 102 milliwatt test line".
This line is usually found in xxx-958-nnnn or xxx-959-nnnn ranges.
I'm in area code 323 in Los Angeles.
Does anybody know the test number here??
Thanks,

WCTDM-24xxp woes
I am currently running Asterisk 1.2.8, on an AMD Sempron 3100+ (ASUS K8N
Nforce based board). I am using a Digium wctdm24xxp to terminate 8 (2x
quad) FXO lines. Using ztmonitor (From zapata) I cannot see that there is
any registerable incoming volume from these lines. I've been running them
at rxgain = 25 (zapata.conf) to make the audio audible, however this
creates poor call quality issues

PSTN line quality
I'm looking for some input from someone with real experience of
telephony. I am having problems with the sound quality on our PSTN line
calls. Our channel banks are Adtran 600 and 750 and I spent a lot of
time on the phone with Adtran trying to work out the problem.
We are getting hum and noise and very low volume on calls. I can
increase the gain in zapata.conf but that increases the echo

tuning an x100p in Australia for echo cancellation
I have an x100p which suffers from echo (no surprise there apparantly
:), and a few of the things I've read about tuning out echo say the
first thing to get right is the tx and rx gain, and for that you need a
few different types of test lines from the telco (Telstra, Optus,
whatever). Does anyone have any numbers in Australia for such lines? I
think they just need to send out a tone of a
