There's an aspect of the design problem that I neglected to mention. 
Cost-per-port is an important consideration. Ideally, I'd like to have 
one DSP chip handling more than one line. And it would be better if the 
modulation technique were in "soft" (i.e. downloadable) code, as 
insurance against firmware bugs and for purposes of upgrading as new 
techniques are defined.
