Modems
V.29
Network hardware; Modems
An ITU-T standard for facsimile operations that specifies modulation at 9,600 bps, with fallback to 7,200 bps.
V.32
Network hardware; Modems
An ITU-T standard for modem communications at 9,600 bps and 4,800 bps. V.32 modems fall back to 4,800 bps when line quality is impaired.
V.32 bis
Network hardware; Modems
An ITU-T standard that extends the V.32 connexion range: 4,800, 7,200, 9,600, 12,000, and 14,400 bps. V.32 bis modems fall back to the next lower speed when line quality is impaired, fall back ...
V.34
Network hardware; Modems
An ITU-T standard that currently allows data rates as high as 28,800 bps.
V.34+
Network hardware; Modems
An enhancement to V.34 that enables data transfer rates as high as 33,600 bps.
V.42
Network hardware; Modems
An ITU-T standard for modem communications that defines a two-stage process of detection and negotiation for LAPM error control.
V.42 bis
Network hardware; Modems
An extension of ITU-T V.42 that defines a specific data compression scheme for use during V.42 connections.
