          About a year ago, I posted the following to comp.dcom.modems.
********************************************************************

          Many moons ago, I recall learning in a communications theory
     class about Shannon's Law. This law stated that the maximum
     transmission rate thru a channel was twice the bandwidth of that
     channel. Thus, a 4 khz telephone channel would support an 8 khz
     transmission rate.

          Thus, I became curiouser and curiouser as modem speeds
     increased.... has Shannon's Law been repealed, do I mis-remember,
     or what is the magic that permits today's outrageous (and wonderful)
     modem speeds?

**********************************************************************

         I received many responses from the dcom gurus concerning
     the theoretical aspects of modem operation at 28.8. Briefly,
     operation at that speed is possible only under *pristine* line
     conditions... as noted in a tech note from US Robotics.

         For those who are interested, I have the responses to my
     query in a file called shannon.zip available on my digex ftp
     server (address below). Also, I think that comp.dcom.modems would
     be a better place to continue this discussion.....
