CENTILLIUM DELIVERS
INDUSTRY'S FIRST ADSL G.LITE CHIPSET SOLUTIONS FOR JAPAN
Centillium CopperLite
and Optimizer Chipset Solutions Support G.992.2 "Annex C"
Specification, Accelerating Rollout of DSL Services in Japan
FREMONT, Calif., October 19, 1999 - Centillium Communications, Inc.
extended its commitment to international industry standards today by
announcing new CopperLite™ and Optimizer™ chipset solutions
that support Annex C of the ADSL G.lite (ITU-T G.992.2) standard. Annex
C addresses the unique characteristics of copper loop plants in Japan,
which require different modem and central office technology than plants
in the United States (Annex A). These characteristics include paper
insulation for copper wiring and widespread deployment of TCM-ISDN systems.
Annex C describes specifications that solve line interference issues
and allow an ADSL system to coexist with TCM-ISDN in the same binder.
Centillium is the first and only company to make G.992.2 Annex C chipset
solutions available to manufacturers of DSL equipment like modems and
DSL access multiplexers (DSLAMs). Now these companies can sell their
products into the networking equipment market in Japan, accelerating
the rollout of DSL services in the world's second largest economy. Momentum
is rapidly building for ADSL G.lite services in Japan, led by NTT's
announcement of plans to begin rolling out a commercial ADSL service
in the third quarter of 1999. NTT has selected Sumitomo Electric and
other major Japanese networking equipment manufacturers to supply DSLAM
equipment based on Centillium's CopperLite chipset solutions. The service
offers a downstream rate of 500Kbps and an upstream rate of 200Kbps
in the Tokyo and Osaka metropolitan areas.
"Centillium has been in production with the Annex C product for
a few months now," said Faraj Aalaei, co-founder and vice president
of marketing for Centillium Communications. "We worked very closely
with our partners and customers in Japan to develop a chipset solution
that overcomes the interference issues specific to Japanese copper loop
plants. As a result, equipment manufacturers can confidently use Centillium
chipsets as the foundation for building ADSL G.lite products that provide
high-performance Internet connectivity all over the world, including
Japan. In fact, modems based on the Optimizer chipset are the first
to deliver ADSL G.lite connectivity anywhere around the globe."
"The opportunity for DSL services in Japan is enormous," said
Laurie Falconer, DSL Analyst, TeleChoice, Inc. "Unlike the U.S.
market, the Japanese residential market does not have a pervasive coaxial
cable infrastructure capable of being upgraded to handle broadband communications.
DSL is the only technology that will permit broadband network access
from the home in Japan and availability of Centillium's CopperLite chipset
solutions will help speed the rollout of services."
Centillium Chipset Solutions Support G.992.2 Annex A and Annex C
Centillium's CopperLite Central Office (CO) CT-L41SC04 and Optimizer™
Customer Premises Equipment (CPE) CT-L42SU15 chipsets are the industry's
highest performance, lowest power dissipation ADSL G.lite solutions
specifically designed for mass consumer markets.
Centillium has developed patent-pending software technology that implements
either G.992.2 Annex A or G.992.2 Annex C specifications on a single
hardware platform. This provides telecom equipment manufacturers with
enormous flexibility, allowing them to design a single line card for
carriers in Japan and the rest of the world. The CopperLite CT-L41SC04
eliminates costly infrastructure upgrades by offering the industry's
lowest power consumption (600 mwatts /per port) and ensures software
upgradability over time by delivering ample processing power.
Centillium's flexible hardware platform also allows end users to utilize
a single ADSL G.lite modem anywhere around the globe. Centillium's Optimizer
chipset family is the most highly integrated, lowest power-consumption
CPE solution for consumer DSL modems. Based on third-generation patented
technology, the Optimizer CT-L42SU15 dramatically reduces the cost,
form factor, and power usage normally associated with DSL modems. For
the first time ever, modem manufacturers can develop business card-sized
G.lite ADSL modems, while carriers and consumers can leverage the preferred
Universal Serial Bus interface to ease the deployment of DSL services.
