V.34
V.FAST
<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}.
