V.27ter
ITU-T standard for 4800 bps full-duplex modems connected to switched telephone networks.
V.29
ITU-T standard for 9600 bps half-duplex modems included in FAX machines.
V.42bis
ITU-T standard for the compression of asynchronous data. V.42bis is based on a dictionary that looks up
common strings and replaces the strings with code words. This reduces the amount of characters actually being
transmitted. V.42bis has been found to be most effective for file transfers that contain long strings of repetitive
information and least effective for short strings of unique data. It requires LAPM, MNP2, MNP3, or MNP4 as
error correcting.
