56K Faxmodem User's Guide and Reference
Welcome to 56K Information Access
The V.92 standard is an exciting advancement in 56K technology. V.92 offers
three functions to enhance the current V.90 standard.
The first enhancement is the "V.PCM-Upstream" technology, which allows a modem's
upstream communication to reach speeds of 48,000 bps. The V.90 standard limited
upstream speeds to V.34 rates.
The second enhancement is Quick Connect, which permits quicker dial-up
connections by allowing the modem to remember the line conditions of the
connection to a service provider that supports V.92. The first time that you
connect with your service provider, the modem will perform the full training
sequence and store the information it receives. This eliminates the need for
the modem to go through the full training sequence during subsequent connection
attempts, reducing the connection time by 30 - 50%. If the modem is unable to
make an optimal connection any time after the initial attempt, the modem will
perform the full training sequence.
The third enhancement is the "Modem On Hold" technology, which allows your
Internet connection to be suspended when there is an inbound telephone call and
allows you to return to your Internet connection when the call is completed. If
you subscribe to Call Waiting service from your telephone company and you
receive an incoming call, you will receive a message informing you of the
call.* In addition, if you subscribe to Caller ID service, the number of the
incoming call will be displayed. If you are connecting to a service provider
that supports Modem on Hold, you will then have the option to accept the call
or to ignore it. If you choose to accept the call, another message will appear
notifying you of the length of time that the provider's system will wait on
hold before the data connection is terminated.
The V.92 enhancements will not immediately be available with all service
providers. To find out if you are able to achieve a V.92 connection, refer to
the following URL:

Contact your service provider to find out if there are V.92 servers for you to
dial into. This modem is backward compatible and will negotiate the highest
possible speed when connecting to a service provider.
*If your incoming calls immediately forward to voice mail, you will not receive
this message.
