In stereophonic sound, sound is recorded on two different channels and then mixed or blended back together, for an observable effect in playback. This is in contrast to monophonic sound, which involves only one channel. Stereophonic sound is also known as stereo sound or stereo.
V.22bis is an ITU Telecommunication Standardization Sector (ITU-T) standard that extends the V.22 standard by providing a faster transmission rate using quadrature amplitude modulation (QAM) at 600 baud to carry digital data at 1,200 or 2,400 bits per second, although the 1,200 bit rate is more compatible with the standard.
V.22bis is pronounced "v-dot-twenty-two-biss."
V.22bis was developed in 1984 to allow synchronous and asynchronous 2,400 bps full duplex modems to be used on dial-up lines and two-wire leased lines.
Modems that adhere to V.22 standards are intended for use on general switched telephone network (GSTN) connections and on point-to-point, two-wire leased telephone circuits.
The important features of V.22 modems are:
