U.S. ROBOTICS: THE INTELLIGENT CHOICE IN
INFORMATION ACCESS
1
ongratulations! You have just purchased the
Sportster®Voice 56K faxmodem. Since
1976, U.S. Robotics has grown to become a key
manufacturer and developer of information access
technology. U.S. Robotics’ advanced technology
allows you to use your faxmodem to open up a
new world of information access. And now you
can take advantage of the highest transfer rates
available today with our new x2™technology!
As an innovator in the data communications field,
U.S. Robotics has a history of bringing the latest
technology to market at an affordable price.
U.S. Robotics owns the core technology, known
as the data pump, that works in its access
products. This allows U.S. Robotics to bring new
technologies and features to market faster and at
a lower cost while passing the savings on to you.
Be sure to read the following section to learn
more about the latest U.S. Robotics
breakthrough, x2 technology. Your new Sportster
takes advantage of this technology to make
connecting over analog lines faster than ever
before.

Thelatestbreakthroughin
onlinecommunications
Until now, 33.6 Kbps was thought to be the
practical limit for speed over standard phone
lines. Now, x2 shatters that barrier, to bring
you download speeds of up to 56 Kbps.
However, due to FCC rules which restrict
power output of your service provider’s
modems, current download speeds are limited
to 53Kbps. This modem is easily upgradable
to new features and enhancements as they
become available.
Anintegratedend-to-end
solutionfromtheleader
U.S. Robotics is well positioned to bring you
x2 technology. Our Sportster modems are the
world's number one seller, and our Total
ControlTM and CourierTM product lines are
favored by many Internet service providers.
This widespread acceptance allows U.S.
Robotics to offer x2 technology to virtually
anyone.

Takingadvantageofthe
moderntelephonenetwork
x2 technology uses the increasingly digital
telephone network to bring you faster
downloads, by eliminating the analog-to-digital
conversion in the downstream path.
x2 takes advantage of the typical network
configuration found when an analog subscriber
connects to a digitally connected server.
Because it bypasses the analog-to-digital
conversion in the downstream path, x2 can use
nearly all of the available 64K network
bandwidth. (Upstream data, typically less
speed sensitive, travels at the standard V.34
rate.)
The result is a completely new kind of
transmission technique. Based on “encoding”
rather than “modulation,” it can give you
download speeds that you never thought
possible. What’s more, with standard V.42 bis
compression, x2 can download at speeds up
to a blistering 115.2 Kbps.
Thenewstandardforonline
speed
U.S. Robotics has already submitted x2 to the
ITU-T standards committee for acceptance as
the next online standard.

technology, see our World Wide Web page at

Speakerphone
With the addition of an inexpensive set of
externally powered speakers, your new
Sportster Voice modem provides all the
convenience of a full-duplex speakerphone.
Unlike many half-duplex speakerphones, your
Sportster allows you to converse normally
without annoying echoes and distortion. Simply
plug the speakers into the SPEAKER jack on
the modem and you’re ready to go.
PersonalVoiceMail
Personal Voice Mail turns your modem into a
full-featured messaging system. Enjoy the
convenience of professional voice mail in your
home or office for a fraction of the cost.
With Personal Voice Mail, you can record
custom greetings, receive messages, and set up
multiple voice “mailboxes”. You can even
access your voice messages remotely.
Your modem will automatically detect
incoming fax/voice/data calls and route them
appropriately. The included fax-on-demand
feature allows callers to select information from
a list and have it automatically faxed to them.
