MNP 5 Data Compression

The modem masters the Microcom Networking Protocol Level 5.
MNP 5 data compression can only be performed for an error
corrected MNP 4 connection. MNP 5 replaces frequently used
characters by shorter characters, so-called tokens.
MNP 5 cannot re-pack packed data.
5.4.3

V.44 Data Compression

The V44 data compression offers better compression of typical
Internet content than V.42bis. V.44 also requires an error
corrected connected, just as V.42bis, and cannot re-compress
already compressed data.
