CCITT V.17 and V.32bis were both unanimously adopted by the CCITT on February 22, 1991. They are presently being prepared for publication at this time, but since there were no changes made to the "ballot version" released last November most manufacturers have had copies of the "final text" for a long time. > For those who don't know, V.32bis will the standard for communication > at the real speed (not effective throughput) of 14,400bps.

Well, but ISDN is 64000bps raw synchronous throughput, and with V.42bis on top of V.120 you'll see effective throughput of over 250,000bps. > Forval already makes a V.32bis V.42bis modem (also with MNP5) that > sells for about $1000. I want one! :) There are several other companies already shipping V.32bis modems, including Digicom, Penril, Codex, Prometheus, and US Robotics, and many that have announced the intention to do so (like Hayes). Most of these are under $1,000 (Penril and Codex a bit more, which is to be expected).
