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.
nod, I have those emails. The thing is, that was on the Quads. The quads could do analog or digital. The default modem templates were optimized for analog calls not digital. So you would have to make some changes to the Quads to optimize for CT1/PRI. David did clarify however that the HDM's didn't have this problem. But that was when they first came out, who knows whats what since then.
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...
