/ V.44 Modem FAQ
Information on the V.92
/ V.44 technology.
The V.92 analog modem standard adds new features to V.90 modems.
Key features of the V.92 standard include:
- Quick connect, which shortens a modem's connection time by
remembering the line conditions to the dial-up server. It then uses that
information to connect quickly without going through the
training sequence. Users will be able to re-establish a connection
significantly faster than with the previous standard, reducing the
waiting period to establish a connection. The increase in connection
speed depends on local line conditions.
- Modem-on-hold, which emulates the combined voice and data
capabilities of broadband modems by giving users the convenience of
being able to accept an incoming phone call during an Internet session
without losing the dial-up connection. The end user and service provider
modems coordinate with each other to temporarily suspend and then
re-activate the connection without having to end the Internet session.
For Internet users with only a single phone line, modem-on-hold allows
them to handle both data and voice calls over the same line.
- Pulse Code Modulation (PCM) Upstream, which increases the speed
at which information is sent to a network -- up to 48,000
bits per second, compared to 31,200 bits per second with earlier
technology. This is a significant advantage for remote-connectivity
applications involving large file transfers and e-mail attachments.
V.44 is the latest ITU-approved standard for compressing data for
faster throughput. Data compression increases the effective speed of an
Internet connection by analyzing the data and encoding it so that it can
more efficiently. V.44 was developed specifically with the goal of
improving real time Internet use. The most notable benefit for Internet
users is the ability to browse the Web at higher apparent speeds.
