I just heard about V.32bis on this newsgroup, the wonderful 14.4Kbps
full duplex modem protocol. I have several questions:

1. How does it achieve this phenomenal speed? With some sort of
   even more sophisticated constellation? How many points?

2. Does it have the adaptive nature of Telebit multi-carrier
   protocol, that takes advantage of any extra bandwidth beyond
   the promised standard?

3. Is this a finalized protocol, formally adapted by CCITT,
   and

4. has any one implemented this yet? If not, how many years can we
   expect to wait before it is a reality?


Please post publicly, as I am sure many people are also interested
to hear about the nitty gritties.
