Product Features
V.92 Technology
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 31,200 bps.
The second enhancement is Quick Connect, which permits quicker dial-up
connections by allowing the modem to remember the line conditions of 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. You can then return to the connection when the call is completed without losing the connection. If you are connecting to a service provider that supports V.92, you will receive a message informing you of an incoming 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. You will then have the option to accept the call or to ignore it. If you are connecting to a V.92 server and 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 server that does not support V.92, you will receive a message informing you of an incoming call. You will then have the option to accept the call or to ignore it. If you choose to accept the call, your data connection will be terminated.
Included on the Installation CD-ROM is the Instant Update software. The Instant Update software automatically notifies you of any updates to your modem's code.
Contact your service provider to find out when your ISP will offer V.92 technology. This modem is backward compatible and will negotiate the highest possible speed when connecting to a service provider.
* You must subscribe to Call Waiting service with your phone company
in order to use the “Modem On Hold” enhancement.
† If your incoming calls immediately forward to voice mail, you will
not receive this message.
V. Everything Technology
The modem supports all key ITU analogue communications protocols and many
proprietary ones to provide you with ultimate compatibility. The modem
also supports V.25bis synchronous mode using bisync and HDLC protocols
and 2-wire leased line operations for compatibility with many legacy systems.
V. Everywhere Technology
The V.Everywhere technology in this modem allows this modem hardware and
firmware to be used anywhere in the world. A simple setup to configure
the modem for the country of operation is all that is required.
Remote Flash
You can easily upgrade your modems in the field from the convenience of
your local office by enabling the remote “flash” capability
of the modem. See the “Upgrading” chapter of the Command Reference
included on the Installation CD-ROM.
Dial and Dialback Security
The modem provides you with a robust mechanism for providing dial and
dialback security for your network. See the “Dial Security”
chapter of the Command Reference included in the Installation CD-ROM.
Remote Manageability
The modem can be remotely configured and monitored for the convenience
of your local office. See the “Accessing and Configuring Remotely”
chapter of the Command Reference included in the Installation CD-ROM.
