∗∗ IMPORTANT! All x2 products are capable of 56 kbps downloads; however, due to FCC rules
which restrict power output of the service providers' modems, current download speeds are limited to
53 kbps. Actual speeds may vary depending on line conditions. Uploads from users to service
providers travel at speeds up to 33.6 kbps. An x2-capable modem, an x2-compatible analog phone
line and an x2-capable Internet Service Provider are necessary for these high-speed downloads.

Thelatestbreakthroughin
onlinecommunications
Until now, 33.6 kbps was thought to be the
practical limit for speed over standard phone
lines. Now, x2 Technology shatters that
barrier, to bring you high speed downloads. x2
Technology is capable of 56kbps downloads,
but, due to FCC rules which restrict power
output of your service provider’s modems,
current download speeds are limited to 53
kbps. This modem is software upgradable,
allowing easy upgrades to new features and
enhancements as they become available.
Anintegratedend-to-end
solutionfromtheleader
3Com is well positioned to bring you x2
Technology. Our U.S. Robotics 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
3Com to offer x2 Technology to virtually
anyone.

Takingadvantageofthe
moderntelephonenetwork
x2 Technology takes advantage of the typical
network configuration found when an analog
subscriber connects to a digitally connected
server. 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.

Read the section of this manual titled “U.S.
Robotics Modem Update Wizard” (page 41)
for information about using this software (on
the Connections™CD) to update your
modem’s code to the latest version.

3Com has already submitted x2 to the ITU-T
standards committee for acceptance as the
next online standard. For more information on
U.S. Robotics’ x2 technology, see our World

HowtoInserttheModem
NOTE: Before installing your
modem, write down the modem's
serial number in the manual. (The
serial number is on the bar coded
sticker on the modem and on the
outside of the box the modem came
in.) If you ever need to call our
technical support department, the
technical support representative will
ask you for the serial number. This
will help him or her identify the type
of modem you have.
1. Turn off your computer and unplug it from
the electrical outlet.
2. Unplug any peripheral devices (printer,
monitor, keyboard, mouse, etc.) from the
computer.
TIP:If you haven’t added
accessories to your computer before, we
suggest labeling the cords and cables
before unplugging them.
CAUTION:To avoid being
shocked, make sure your computer and
all peripheral devices are turned off and
unplugged from the electrical outlets.
