V.42bis
<communications, standard> An extension of the ITU-T V.42
standard modem protocol to included compression using a
Lempel-Ziv related technique, which detects frequently
occurring character strings and replaces them with tokens.
This is similar to the Unix compress utility. Typical
compression for text is 50% or better; with nearly 20% gain
from synchronous conversion this gives reduces transmission
time by almost 60%.

List of ITU-T V-series recommendations
The ITU-T V-Series Recommendations on Data communication over the telephone network specify the protocols that govern approved modem communication standards and interfaces.
Note: the bis and ter suffixes are ITU-T standard designators of successive iterations of a standard (bis and ter are derived from the Latin for "twice" and "thrice").
