SKOKIE, Ill.--(BUSINESS WIRE)--May 7, 1997--U.S. Robotics
(NASDAQ:USRX) announced that it licensed discrete multi-tone (DMT)
technology from Aware, Inc. for future releases of ADSL products
under development.
   U.S. Robotics will develop software that incorporates Aware's
DMT technology into the next-generation Digital Subscriber Line
Access Multiplexers (DSLAM) and customer premise equipment (CPE)
available next year.  The design will use a reprogrammable Digital
Signal Processor (DSP) chip so that field units support software
updates.  The companies will collaborate to ensure interoperability
with Aware's other licensees building ADSL equipment in order to help
telephone service providers accelerate ADSL to the mass-market.
   DMT is a technique standardized by ANSI and ETSI for providing
Digital Subscriber Line (DSL) services' multi-megabit data
transmission over local-loop telephone lines.
   "Aware has the best technology and the most productive
relationships with other key ADSL vendors, so that by working
together, we can quickly establish wide interoperability.  We can
adhere to evolving defacto and dejure ADSL standards by means of
modem software upgrades.  We can minimize cost by using a
general-purpose DSP chip.  These factors protect our customers'
investment no matter what directions standards take."  said Laura
Howard, vice president of business development for U.S. Robotics
Broadband Access Communications Division.
   "Aware brings DMT technology and a number of ADSL systems vendors
using the DMT chipset from Aware and Analog Devices Inc.  U.S.
Robotics, as a major remote access vendor, can help us drive
interoperability among all,"  said Jim Bender, Aware president and
CEO.
