equalization
A compensation circuit designed into modems to counteract certain distortions introduced
by the telephone channel. Two types are used: Þxed (compromise) equalizers and those
that adapt to channel conditions. U.S. Robotics high-speed modems use adaptive equaliza-
tion.
error control
Various techniques which check the reliability of characters (parity) or blocks of data.
V.42, MNP, and HST error-control protocols use error detection (CRC) and retransmission
of errored frames (ARQ).
