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 in the computer's
message window. 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. If you are connecting
to a service provider that does not support V.92, you will still have
the option to accept the call or to ignore it. If you choose to accept
the call, your data connection will be 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.
