Symmetrical DSL Chipsets for Japan
Business Editors/High-Tech Writers
FREMONT, Calif.--(BUSINESS WIRE)--Sept. 5, 2000--
Sumitomo Electric Industries to Deploy Central Office and
Customer Premises Equipment Based on Centillium's G.dmt Annex H
CopperFlite DSL Chipsets
Demonstrating continued leadership in broadband communications
technology for Japan, Centillium Communications, Inc. (Nasdaq:CTLM)
announced today availability of software to enable CopperFlite Central
Office (CO), CopperFlite Utopia, and Flite Optimizer Customer Premise
Equipment (CPE) chipsets to comply with the G.dmt (G.992.1) Annex H
standard for Synchronized Symmetrical Digital Subscriber Line (SSDSL).
Now Japanese businesses and residential users can utilize SSDSL for
high-speed access to the Internet and corporate networks reaping the
full benefits of broadband technology.
Sumitomo Electric Industries, the leading DSL equipment vendor in
the Japanese market, introduced Japan's first residential Asymmetrical
DSL (ADSL) equipment based on Centillium chipsets in 1999 and will
manufacture Annex H SSDSL CO equipment and CPE utilizing Centillium's
CopperFlite Octal CO chipset and CPE utilizing CopperFlite Utopia CPE
The ITU G.dmt Annex H specification is the standard allowing
symmetric DSL to coexist with TCM-ISDN within the same bundle,
addressing the unique requirements of Japanese copper loop plants.
Centillium's Annex H implementation can achieve data rates well over 3
Mbps for SSDSL, exceeding the requirement of 1.6 Mbps. Japan has one
of the largest installed bases of ISDN in the world with more than
seven million ISDN subscribers.
"Centillium's technology leadership in developing DSL chipsets
which address the special needs of the Japanese market has been
unmatched," said Mr. Yoshikazu Nishiwaki, general manager of Sales &
Marketing, Sumitomo Electric Industries. "By using Centillium's highly
integrated low power products for Annex C ADSL and Annex H SSDSL, we
are able to offer a complete suite of high performance products for
both residential and business markets in Japan."
Centillium's G.dmt Annex H Chipsets
Centillium's CopperFlite CO chipset is a fully programmable DSL
transceiver. Each port consumes less than 1/2 a watt of power and
occupies about one square inch of total board space. CopperFlite uses
just two chips to deliver the integrated silicon and software needed
for a low-power, high-density 8-port SSDSL transceiver.
Centillium's CopperFlite Utopia and Flite Optimizer chipsets each
deliver a complete CPE transceiver with just two chips, significantly
reducing the form factor, power-usage, component count, and BOM costs
normally associated with broadband access devices. The CopperFlite
Utopia chipset interfaces with Ethernet for such products as routers
and gateways. The Flite Optimizer chipset supports USB, PCI, Mini-PCI,
and CardBUS interfaces for PC Centric solutions.
In addition to support for Annex H, Centillium CopperFlite and
Flite Optimizer chipsets conform to a wide range of international DSL
standards, including Turbo G.lite, G.lite (ITU-T G.992.2) Annex A and
C, and G.dmt (ITU-T G.992.1) Annex A, B, and C.
Centillium's CopperLite chipset, which has been shipping to
network equipment makers since early 1999, is the only ADSL Annex C
solution that has been actively deployed by NTT and CLECs in Japan.
