Does anyone know a Type 102 milliwatt number that I can call to adjust the RxGain? I have tried the telco but no one is responding on their number.

However, before you go blindly upping the value, you should know that you run
the risk of making echo problems worse by messing around with rxgain/txgain.
However, tuning rxgain/txgain is something that you *should* do on all your
FXO ports anyways... properly tuned ports will create far less echo than
those using default values most of the time.
Tuning rxgain/txgain is a little bit of a tedious task however, and I can;t
really say there are alot of good guides out there on how to do it.
The way I did it was first I tuned my rxgain by dialing a telco-owned
milliwatt test number (should be able to get this from your telco, i believe
its referred to as a Type 102 milliwatt test). You use that to tune rxgain,
then the way I tuned txgain was by using the app_milliwatt application to
essentially create my own milliwatt test number (need multiple FXO ports to
do this), so basically i;d dial out from one FXO port and back into the other
and adjust the txgain until i got it right...
You need to use ztmonitor to watch the levels as you adjust tx/rxgain, I
believe the magic number you want to hit in ztmonitor is around 14840 (thats
off the top of my head so i might be off)...

You could always do a hairpin call, make the call out on the PSTN to
your own number and have asterisk supply the Milliwatt signal. That's
how I set up my current client's Zap settings |

How do you get asterisk to send a 102 Milliwatt signal?

Nice trimming!
Your method doesn't really take into account the local loop from the
telco, does it?
The earlier suggestion is the correct way to do it
The only missing piece was Sanjay's location, and the location of the
box he needs to set up.

The Milliwatt() dialplan application sends a 1000 Hz tone. (I'm still
waiting for the developers to agree that it should be 1004 Hz, but
that's another issue.)

Ok how do you use this then?
I dialed 909-390-0002 Milliwatt and apart from hearing a tone my
ztmonitor was just on full to the right.

That'll only work well if you have your txgain pre-tuned... kinda need a telco
controlled one (or another * box that you know is tunted properly) to use as
a reference.

app_milliwatt provides a Milliwatt() function
I actually wrote up this guide on tuning rx/txgain yesterday and pointed
Sandjay towards it... which I;m assuming is why he;'s asking for the number:
http://www.mattgwatson.ca/2008/05/howto-tune-zaptel-dahdi-fxo-interfaces-on-asterisk-pbx/
it also covers how to generate the 102 millliwatt signal.
I basically learned the procedure from a post dating back to 2004 to this
list... hopefully its fairly accurate... i wrote the guide more or less from
memory without actually trying it.

The visual bar indicator from ztmonitor shouldn;t be used when using a
milliwatt number, you want to run ztmonitor with -vv so you get the numerical
indicators. THe goal is to try and hit 14844 on your Rx. I have no idea why
14844 is the magic number... but i;m sure somebody else here could explain
that.

1004Hz has been the Telco standard for many a year.
Just another example of why the developers need to go to a basic Telco
school before reinventing the wheel ( sometimes incorrectly )

1004Hz has been the Telco standard for many a year.

You can already do that with simple dialplan:
exten => 8114,1,Answer
exten => 8114,n,PlayTones(1004/1000)
exten => 8114,n,Wait(300)

There is no need to insult the developers. Yes, there's a reason why the
typical milliwatt application is not exactly 1000Hz. I think we've actually
left the Milliwatt application the way that it is for historical reasons,
ironically enough.

That'll only work well if you have your txgain pre-tuned... kinda need a telco
controlled one (or another * box that you know is tunted properly) to use as
a reference.

This is true, most definitely. However, in a pinch it's helped  |
