V.34
<protocol> An ITU-T standard modem serial line protocol using symbol
rates of 2400, 2743, 2800, 3000, >3200 and 3429 and up to 28800 bits per second.
The official V.34 draft recommendation was titled:
Modem operating at data signalling rates of up to 28 800
bit/s for use on the general switched telephone network and
on leased point-to-point 2-wire telephone-type circuits.
During the lengthy process of approval by ITU-T, many manufacturers
released 28.8 kbps modems described as "V.FAST". The
V.34 recommendation was ratified by ITU-T on 20
September 1994. Rockwell and US Robotics both have
seats on the ITU-T, and have both released chip
set/BIOS combinations that they feel will meet V.34.
V.34 modems will also support V.FC if the
manufacturer currently supports V.FC (e.g.
Rockwell). Some (all?) V.34 modems will also support
line probing.
