V.34 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. {ITU document (http://itu.int/itudoc/itu-t/rec/v/v34_25302.html)}. (1998-07-03)
