V.21 The CCITT standard for 300bps communications. Domestic modems
follow the Bell 103 standard, but V.21 can accept international calls at
300bps.
V.22 The CCITT standard for 1200bps communications. The domestic
equivalent is the Bell 212A standard.
V.22bis The CCITT standard for 2400bps.
V.23 CCITT for 1200bps with a 75bps back channel. This is mostly used in
Europe and South America.
V.24 CCITT serial interface standard (EIA/RS232-D).
V.32 CCITT standard for 9600bps and 4800bps communications.
V.32bis CCITT standard for an extensive range of high-speed modems operating
at 14,400bps, 12Kbps, 9600bps,
7200bps, and 4800bps.
V.42 CCITT standard for detection and negotiation for LAPM (Link Access
Procedure for Modems) error control. V.42 will also support MNP levels
2-4.
V.42bis An extension of V.42 specifying the data compression protocol for use
with V.42.
V.34 ITU-TSS protocol. It can operate up to 28,800bps for data and 14,400bps
for send/receive fax.
