Does anyone know:
  1.  How to obtain a copy of the V.32 standard mentioned later
      in the subject article for 9600 bit/sec dialup?
  2.  Any other good papers (hopefully readable without too much
      mathemagic) on trellis coding and other techniques used in
      these incredible-by-212-standards modems?  I'm starting with
      Gottfried Ungerboeck's "Channel Coding with Multilevel/Phase
      Signals" in IEEE Trans. Info. Theory, IT-28 #1, January 1982.
      This is rough going for me, so pointers to more directly
      relevant, diluted, tutorial type articles would be much
      appreciated.

I'm fascinated by the possibility of squeezing a useful bandwidth
from my crummy home phone to a computer or network.
