Type ’show modems ?’ for help on detailed modem displays.
PCM Upstream is also part of the V.92 protocol, but is not not supported in the
first round of V.92 code.
V.44 support for modems (CSM6 MACs only)
This feature is not visible to the user and there are no new parameters.
V.44 uses a new compression scheme that compresses HTML (and other data with
similar patterns) for faster downloads. The result is an average of 30-40% faster
throughput over older algorithms.
V.44 is a third compression scheme, supplementing use of ITU standard V.42bis
and the old MNP scheme.
You will see V.44 references in statistics for this release. For examples, see “V.92
support for modems (CSM6 MACs only, for this release)” on page 2-6.
Note: V.92 references may also be seen in show_session_table and
show_session_log.
Note: Although V.44 may appear in the same examples used for V.92, it is not
tied to V.92. Either may be implemented independent of the other.
