<p class="MsoNormal"><font color="black" face="Times New Roman" size="3"><span style="font-size: 12pt; color: black;">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.<br>

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