Actually the V.34 standard uses the Tx level defined by the %L command as

the *maximum* not the starting point.

Yes it *is* implemented in the M34F - it's a standard part of V.34!



Unfortunately a lot of the problems that people have are due to Telstra and

not V.34 or individual brands of modems.  The Tx level set by the %L command

is really only effective from your modem to your local exchange after that

Telstra exchange equipment sets/holds the signal/attenuation level.  But,

some line cards are faulty and attenuate the signal much more that the

recommended 6dB.



Fortunately, I have a pretty good line and I use %L13 (-13dBm, default) and

I get receive levels around -21dBm.  I'm happy. ;-)
