There was some discussion on transmit levels a while back -- check the archives. If I remember right, David Bolen said that ANS made a habit of setting all their modem pools (for AOL mostly) to -13dBm. We had a few people have problems when we tried backing ours down, so for now I've left it alone until I can get a better idea. Complicating things more is that we have both Quads and DSP's, and the Quads default to -11, but the DSP's default (or at least used to default) to -12. The Courier I-Modem I have at home defaults to -12. What the actual transmit power works out to in all these cases at each modulation is anyone's guess...
