*Which protocol will be used? Assuming that the ISP
supports both, it
depends on the firmware. Some version will prefer K56flex,
others will Prefer V.90. Click

How
do I disable X2,V.90 or Flex to be able to
connect to 33.6 K modem.
If
you have a 56K modem but you're dialing into a V.34 modem bank, your
modem will still try to negotiate a 56K connection, even though it's
impossible. You may want to use one of the commands below to tell the
modem to not attempt a 56K connection. Check before if your modem supports
X2 or Flex only, X2 with V.90 compatible or Flex with V.90 compatible.

DIAL-UP ACCESS GETTING FASTER
The new V.92 dial-up modem standard promises
to maximize the limited potential of analog connections. Once Internet
Service Providers upgrade their hardware to handle the V.92 standard,
the new protocol will shave a few seconds off of logon time, allow
free Internet call waiting, and speed data conversion for faster downloads
and uploads. Actiontec's Lesley Kirchman notes that, while the future
definitely belongs to broadband, the V.92 standard could be the last
great leap forward in analog modem technology. ISPs America Online,
EarthLink, and MSN have yet to adopt the technology because it is so
new, but representatives have promised that the companies will soon
test and debug V.92. Among the new features are "Quick Connect"
technology, which helps a modem to learn connection patterns and hook
up more quickly, and the new V.44 compression protocol that makes text
and Web pages move faster. (Washington Post, 23 February 2001)
