A CCITT standard for data compression. It can compress data with about a 3:1 compression ratio, 4:1 under the right conditions. Any modem with V.42bis also has V.42 error control.
data compression, theoretically capable of 4:1, more commonly gets 1.5:1 to 2.5:1 on non-compressed data. In practice, it is usually limited by DTE (serial port) speeds.
CCITT industry standard for modem data compression (Up to 4:1 compression)
An international data compression protocol that can compress data by as much as 4-to-1.
A CCITT Recommendation for data compression on a modem circuit.
CCITT data compression protocol. Two modems which both have V.42bis can compress data "on the fly" at one end, and decompress it again at the other end, so that throughput can be effectively doubled under ideal conditions. V.42bis incorporates MNP 5 (and V.42), so all V.42bis modems can communicate with MNP 5 modems.
V.42 + modem compression up to 4:1 (and see eg MNP5)
ITU standard protocol for doing compression.
CCITT analog modem data compression standard. Provides a theoretical maximum of 4:1 compression, although 2:1 is more commonly experienced.
