<DIV></DIV>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><BR>Regards,<BR>Sanjay Rajdev<BR><BR>----- Original Message

Regards,<BR>> Sanjay Rajdev<BR><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><BR><BR>--
