  1.    I thought the D channel was already used on a POTS line, anyway...
  2.    In a somewhat different vein... aren't the B channels derived channels,
  and if so, is there anything magic about 56 or 64 kbps?  What if there
  were lots of 9.6 kbps derived channels. and you only used as many as you 
  needed, at that time.... they everyone with an open connection would be 
  using at most about 17 percent of what a POTS line uses now, for 
  interoffice trunkage....
