V.32bis

V.32bis

(communications, standard)V.32 twice. An extension of theITU-T V.32 modem protocol allowing 14400 bits persecond with fall back to 12000bps, 9600bps, 7200bpsand 4800 bps.

The modem should select the appropriate speed according tothe current line conditions.

V.32bis

An ITU standard (1991) for asynchronous and synchronous 4,800, 7,200, 9,600, 12,000 and 14,400 bps full-duplex analog modems using trellis-coded modulation (TCM) and echo cancellation. It supports rate renegotiation, which allows modems to change speeds as required.
