Frequently Asked V.92 Questions
What is V.92?
V.92 is a new standard for dial-up communications that offers several important
improvements over the existing V.90 standard. These improvements are intended to
make communications faster, easier and more enjoyable. V.92 and its companion
compression standard V.44, have been officially adopted by the ITU, the International
Telecommunications Union.
What makes a V.92 modem faster than V.90?
There are three features that allow the V.92 modem to give you faster speeds.The first is
the V.92's improved "automatic negotiation" or "handshake" which is the way modems
determine compatibility and decide what standards to use to communicate. With a
typical V.90 modem this can take as long as 30 seconds. With QuickConnect, the entire
process can take as little as half that time.The V.92 Modem also includes V.44, a new
international data compression standard. V.44 was designed specifically for the
Internet, and can double the effective speed of your Internet page loading. Finally, the
V.92 standard increases the upload speed by as much as 30%., from 33,600 bps (the
maximum upload speed using V.90) to 48,000 bps.
How does V.44 increase the speed of my web browsing?
V.44 is the latest compression standard approved by the ITU. Compression increases
the effective speed of your connection by analysing the data and encoding it so that it
can be sent more efficiently. The old standard (V.42bis) was created about 10 years ago,
so it wasn't designed with the Internet in mind. V.44 was, and it is therefore much more
efficient at compressing web pages - up to 100% more efficient in some cases.
Do I need a special service or new ISP?
No. But you may not be able to take advantage of all these features right away. While
your current ISP will almost certainly support V.92 and V.44 at some point, it may take a
while before the equipment manufacturers that your ISP or online service uses sends
them an upgrade, or until they implement the upgrade. However, V.92 and V.44 are true
international standards, so over time you can be assured of nearly universal support.
In the meantime you can use the V.90 protocol, which is also in your V.92 modem, until
your ISP switches over.
