Lucent Technologies and 3Com Corporation Agree to Begin 56K Modem Compatibility Testing Using New "V.pcm" Standard

January 20, 1998 1:00 PM EST

Lucent Technologies (NYSE:LU) and 3Com Corporation (NASDAQ:COMS) today 
announced that they will conduct joint interoperability testing of their
56-kilobits-per-second (Kbps)(1) industry-standard modems and modem chip

The collaboration will ensure compatibility between the two companies'
modem products using an emerging industry standard referred to as V.pcm. 

An International Telecommunications Union (ITU) committee began working in
April 1997 to develop a standard for "pulse code modulation" (PCM) modems
-- the fastest analog modems available today. On December 4, 1997 the ITU
working group agreed to a compromise on key technical issues referred to as
V.pcm. The forthcoming standard, comprised of an equitable mix of K56flex
and x2 technology, will be determined at a plenary meeting of the ITU Study
Group 16 in Geneva, Switzerland February 5-6. 

Both 3Com and Lucent expect to have interoperable products on the market
shortly after that ITU meeting, as well as software upgrades to make
existing K56flex(TM) and x2(TM) modems compliant with the
soon-to-be-released standard. 

"Interoperability testing is one of the first steps toward ensuring
compatibility," said Dale Walsh, senior vice president of advanced
development at 3Com. "Our goal is to provide Internet Service Providers
(ISPs) and end-users with universally compatible 56K service as soon as
possible. This is a significant win for consumers because we will be able
to deliver interoperable standards-based products to the market much
faster. We commend Lucent for its support of the ITU compromise reached
earlier this month and look forward to working with them." 

"3Com and Lucent are striving to have standards-compliant products on the
market as quickly as possible, and to upgrade the Lucent K56flex and 3Com
x2 client and server modems already in use with V.pcm software," said Bob
Rango, general manager of modem integrated circuits for Lucent's
Microelectronics Group. "We expect other vendors will join this effort when
they have standard-based products to test."
