CVX Multi-Service Access Switch 4.1 Release Notes
V.92 support for modems (CSM6 MACs only, for this release)
Although V.92 modem code is not included in this release, the 4.1 release is V.92
ready. V.92 modem code is available for Beta testing, and has the following new
features:
• QuickConnect gives reduced modem handshake time, resulting in up to 40%
faster connections, by remembering call setup details of the previous call.
Remembered details include digital impairments, channel frequency response,
and other characteristics that determine modulation and initial connect speed.
• Modem-On-Hold allows the user to resume their connection to the Internet
without re-authentication or modem negotiation after taking or placing a
voice call.
You may see V.92 references in statistics for this release. For example:
