( BW)(ADSL-STANDARDS) DMT silicon vendors charging ahead to achieve
ADSL interoperability goals
CLEARWATER, Fla.--(BUSINESS WIRE)--May 12, 1997--
Standards group's efforts will enable consumers access to advanced communications services such as high-speed Internet access over ordinary copper wire
Mass deployment of Asymmetric Digital Subscriber Line (ADSL)
technology is getting closer, thanks to the efforts being put forth
by such industry-leading silicon developers as Alcatel, Amati,
Analog Devices/Aware, Motorola Semiconductor, Orckit and Texas
Instruments.
The companies Monday reported on progress that has been made in
the ANSI T1E1.4 Standards Body.
The standards group has been diligently focused on drafting
Issue II of the ADSL standard which, among other things, seeks to
achieve interoperability among different vendors' Discrete Multitone
(DMT)-based ADSL silicon and equipment. DMT is an international
standard for ADSL technology, recognized by ANSI, ETSI and most
recently by the International Telecommunications Union (ITU).
Interoperability has been cited as one of the key success
factors for mass deployment of ADSL. A comprehensive, clearly
written standard that is based on proven technology will provide the
basis for the interoperability work ahead. Although other
techniques based on proprietary single source technology exist, such
as Carrierless Amplitude/Phase (CAP) modulation and Quadrature
Amplitude/Phase (QAM) modulation, these are not standardized and are
incapable of interoperating with the standard DMT-based silicon and
equipment.
For the ADSL user, interoperability of standards-based modems
provides greater confidence that the technology will flourish. In
addition, interoperability will allow a user in Virginia to achieve
multimegabit access speeds with the same modem if they move to
California.
This week, the ANSI T1E1.4 working group is finalizing Issue II
of the ADSL specification. Most of the work for Issue II is focused
in the following areas:
-- Backwards compatibility with Issue I of ANSI T1.413
-- Clarifications to Issue I text for multi-vendor
interoperability
-- Rate adaptation both at start-up and during operation (RADSL)
-- The transport of ATM cells over ADSL
-- Extending the highest data rates to over 8 Mbps
-- Reducing the overhead for increased upstream capabilities
Since January 1996, 18 vendors and service providers have made
more than 150 contributions towards Issue II of the existing ADSL
standard. Issue II is expected to culminate in a new issue of the
current standard by the end of this year. To date, eight
independent semiconductor companies have DMT-based ADSL projects
underway or chipsets available, and more are continually entering
the market. In fact, more than 40 vendors are actively developing
DMT-based equipment. Meanwhile, semiconductor vendors continue to
increase functionality, and reduce system chip count, power
consumption and cost, to enable mass deployment of ADSL-based
services.
"The standards process is a key ingredient for the successful
evolution of telephone networks worldwide," said Tom Starr, chairman
and ANSI T1E1.4 working group. "As evidenced by the
accomplishments of this group, an open forum where all companies
work together to develop specifications can bring a multitude of
benefits to the industry. I am pleased with the high levels of
cooperation demonstrated by the working group in the development of
an Issue II specification for ADSL. This will set the stage for
multi-vendor interoperability."
DMT Technology
In March 1993, the American National Standards Institute (ANSI)
working group T1E1.4 selected DMT technology as the standard line
code for ADSL. This selection was made from a pool of competing
technologies, including CAP modulation and QAM modulation. DMT's
most significant advantage is its ability to dynamically adapt to
the line conditions to attain the maximum throughput per channel.
As a result, DMT modems can reach more customers providing greater
coverage for service providers. A DMT-based transceiver has
sometimes been called "The Optimized Transceiver" for this reason.
In a separate action, the ITU Study Group 15 recently undertook
the task to address ADSL for worldwide portability and has agreed to
generate short ITU Recommendations pointing to ANSI T1.413.
About the Companies
Alcatel's activities in North America include the design,
manufacture and service of a full line of voice, data, video and
multimedia telecommunications products -- such as ATM switching
systems, digital cross connects, DSL systems, fiber optic
transmission systems, optical amplifiers, microwave radios, wireless
communications switches, video codecs, and network management
systems. The telecommunications and broadcast industries, private
operators and corporations use these products to create high
performance networks. The global operations of Alcatel make it one
of the world's leading communications equipment manufacturers.
Alcatel is part of the Alcatel Alsthom group, (NYSE:ALA), which
maintains its headquarters in Paris.
Amati Communications Corp. (NASDAQ:AMTX) is a pioneer and
leading developer of advanced transmission equipment utilizing DMT
technology for the ADSL, Very High-Speed Digital Subscriber Line
(VDSL) and cable modem markets. The DMT technology was first
developed by Amati, who holds the ADSL/DMT patents and has licensed
the technology to companies such as Nortel and Motorola. Amati has
been involved in standards-based ADSL trials using DMT longer than
any other supplier in the market. Amati has been supplying DMT
commercial modems since early 1996 at speeds from 1.5 Mbps to 8 Mbps
for services ranging from Internet access to video broadcast. These
trials include services being offered by PTTs in Europe,
Asia-Pacific and Australia, with such companies as Philips, Italtel,
Tadiran and Samsung. In the U.S., Amati is providing ADSL/DMT
equipment in GTE's current Internet access trials in the states of
Washington and Texas.
Additionally, Amati is also a provider of network connectivity
systems for the internetworking and OEM marketplaces. the
company's connectivity products include local area network
gateways, client-based workstation software and network data
