V.17 Fax

A ITU-T standard for making facsimile connections at 14400 bps,

12000 bps, 9600 bps, 7200 bps.

V.21

A ITU-T standard for modems operating in asynchronous mode at

speeds up to 300 bps, full-duplex, on public switched telephone

networks.

V.22

A ITU-T standard for modem communications at 1200 bps, compatible

with the Bell 212A standard observed in the U.S. and Canada.

V.22 bis

A ITU-T standard for modem communications at 2400 bps. The

standard includes an automatic link negotiation fallback to 1200 bps

and compatibility with Bell 212A/V.22 modems.

V.27

A ITU-T standard for facsimile operations that specifies modulation at

4800 bps, with fallback to 2400 bps.

V.29

A ITU-T standard for facsimile operations that specifies modulation at

9600 bps, with fallback to 7200 bps.

V.32

A ITU-T standard for modem communications at 9600 bps and 4800

bps. V.32 modems fall back to 4800 bps when line quality is impaired.

V.32 bis

A ITU-T standard that extends the V.32 connection range: 4800, 7200,

9600, 12000, and 14400 bps. V.32 bis modems fall back to the next

lower speed when line quality is impaired, fall back further as

necessary, and also fall forward (switch back up) when line conditions

improve.

V.34

An ITU-T standard that currently allows data rates as high as 33,600

bps.
