U.S. ROBOTICS ANNOUNCES MOST COMPLETE V.34 LINE IN THE INDUSTRY, INCLUDING
DESKTOP, RACKMOUNT, LAN-BASED AND PCMCIA PRODUCTS

U.S. Robotics Only Company Providing Data Center, Network, Desktop and
Portable V.34 Solutions

SKOKIE, Ill., -- July 19, 1994 -- U.S. Robotics, Inc. (NASDAQ:USRX) today
announced its complete V.34 product line. The company will offer ITU-T
V.34 products in four categories, creating the most broad-based V.34
product line in the industry. Its V.34 product offerings will include:
desktop modems; PCMCIA modems; network communications and remote access
products; and data center products.

The company's first V.34 product, the Courier desktop modem, is expected to
ship in mid-August, 1994. The Sportster V.34 product will follow soon
after, and is expected to ship by the end of August, 1994. Courier and
Sportster V.34 upgrades will also be available in August. Other V.34
products will be available by the end of the calendar year The company has
not yet disclosed pricing for all its V.34 products.

"U.S. Robotics is the first company to provide an enterprise-wide
communications solution, allowing personnel in the field, branch offices,
data centers and home users to reap the time- and cost-saving benefits of
V.34," said Jonathan Zakin, U.S. Robotics executive vice president.

"To take advantage of V 34, every dial-up application must incorporate V.34
products on each end of the connection," added Zakin. "Remote access,
telecommuting, high-speed file transfer, bulletin boards -- none of these
applications can benefit from V.34 unless both the host sites and the
remote sites support it. U.S. Robotics customers have the advantage of
standards-compliant products designed to work together in any wide area
network environment, allowing them to reap the benefits that V.34
provides."

New V.34 Products: Rackmount and PCMCIA

U.S. Robotics has nearly thirty products that are upgradable to V.34.
Additionally, the company is announcing new products to make its V.34
product family complete.

In the portable arena, U.S. Robotics will offer a V.34 PCMCIA product, for
PCMCIA 2.0 slots. Like all U.S Robotics V.34 products, the new PCMCIA
modem will be backward-compatible with ITU-T V.32 bis for 14,400 bps data
transmission and other slower-speed protocols. The product will also
include ITU-T V.17/14,400 bps fax capabilities. List pricing has not yet
been established. The product is expected to ship this fall.

U.S. Robotics will also offer a variety of V.34-compliant cards for use
with its Total Control Enterprise Network Hub and Transaction Processing
Hub rackmount systems. Products include quad analog, digital and
analog/digital cards (four modems per card), and dual card V.34 analog
modems (two modems per card). U. S Robotics' digital and analog/digital
cards are for use with T-l systems; the analog/digital cards also support
analog communications. The products will allow backbone services, online
services, corporate data centers and Regional Bell Operating Companies
(RBOCs) to take advantage of V.34 capabilities. Total Control V.34
products and pricing will be available this fall.

Designed for the Future: Desktop, LAN-Based, Rackmount Products Upgradable
to V.34

For several years, U.S. Robotics has been creating designs with an eye
towards the coming V.34 standard. Courier modems and Shared Access
LAN-based products have been based on upgradable designs since mid-1992,
assuring an easy upgrade path to V 34. U.S. Robotics has also developed
Total Control and Sportster products that are upgradable. Upgrade paths
include FLASH ROM software download, daughterboard upgrades and EPROM
(chip) upgrades. The company's current V.34-upgradable product offerings
include:

Desktop Products

U.S Robotics' premier V.34 desktop product is the Courier "V.Everything"
desktop modem, the only product to support all three high-speed modem
protocols (AT&T V.32 terbo for 19.2 Kbps, Rockwell V.Fast Class for 28.8
Kbps and the ITU-T V.34 standard). The "V.Everything" modems, available
since early June, 1994, provide a free, FLASH ROM software upgrade to
V.34. List prices for these products range from $545 to $795.

Also available are the company's value brand Sportster desktop modems.
Current Sportster V.Fast Class products are upgradable to V.34 via a $29
EPROM chip upgrade. Alternatively, they may send their modems to the
company, and U.S. Robotics will replace the chip for $49. These products
support V.FC, V.32 bis and all slower-speed protocols; list pricing ranges
from $299 to $329.

LAN-based Products

The Shared Access LAN modem 2.0 includes dial-in remote node/remote control
capabilities, dialin PPP support, dial-out capabilities, and dial-up
LAN-to-LAN routing. The product is upgradable to V.34 via FLASH ROM;
previous models are upgradable to V.34 via daughterboard swap.

The Shared Access COM server is an open platform product supporting a
variety of network communications software for remote control,
message/mail routing and modem sharing. The product is upgradable to V.34
via FLASH ROM; previous models are upgradable to V.34 via daughterboard
swap.

Rackmount Products

In addition to its new V.34 high-density rackmount products, U.S. Robotics
will provide upgrades to V.34 for Total Control dual-card modems Upgrades
