   I *do* run into crosstalk here at zswamp. The modem line runs down the 
black/yellow pair around my voice line, and I can hear - and so can the 
other party on the line - DTMF codes and carriers from the other line. Of 
course, these are many deciBels below the conversation, so they're not 
interfering and I expect that they'd be even less significant if I were 
speaking, as another modem would, much louder.

   Still, I can't help but wonder if, under certain marginal conditions, that 
crosstalk might be the difference between a usable connection and a noisy 
one.
