Industries to Bring a Full Range of DSL
Solutions to Japan
Business Editors/High-Tech Writers
FREMONT, Calif.--(BUSINESS WIRE)--March 6, 2001--
Sumitomo Electric Utilizes Centillium CopperFlite Chipsets In
Leading Edge MegaBit Gear CU4000 DSLAM
Centillium Communications, Inc. (Nasdaq:CTLM), innovator of
broadband communications technology, today announced a partnership
with Sumitomo Electric Industries (SEI) to provide a full range of DSL
technology to carriers in Japan. SEI recently announced availability
of its MegaBit Gear(TM) CU4000 DSLAM, which supports multi-mode ADSL
(Annex A and C) and symmetric DSL (Annex H) for Japan and throughout
the world. Centillium's CopperFlite multi-mode chipset, which is the
only DSL chipset that conforms to the Annex C and H standards for
Japan, is the basis for the CU4000 product.
Annex C addresses the unique requirements for operating with
Japan's existing telecommunications network, where time compression
multiplexing integrated services digital network (TCM-ISDN) is widely
deployed. The prevalence of ISDN service significantly increases the
adverse effect of crosstalk from other lines in the loop bundle, a
serious barrier for the wide deployment of ADSL in such environments.
Centillium's innovative and patented technology is the foundation of
the Annex C standard that overcomes the crosstalk problem and enables
Japanese carriers to deploy DSL in the same bundles that contain ISDN.
Centillium's Annex H solution, which also addresses the unique
network characteristics in Japan, provides symmetric DSL for customers
requiring greater bandwidth upstream than is available in typical ADSL
services. Centillium's technology features support for multiple
embedded 64 kbps channels carried on a single DSL line, which can be
used for applications such as channelized voice over DSL (CVoDSL) and
ISDN over DSL.
SEI's MegaBit Gear CU4000 Series DSLAMs are scalable, high
capacity, standards-based platforms that can accommodate up to 480
lines in a 23-inch wide chassis. Utilizing the latest ATM technology,
the CU4000 series offers service providers extensive bandwidth
management capabilities and network accessibility. With integrated,
front-access shelves, the CU4000 series greatly improves system
maintainability. Additionally, the CU4000 series provides superior
reliability by offering redundancy for the DSL lines, high-speed
uplinks and ISDN clock cascade connection.
"With Centillium's network-proven CopperFlite chipsets, SEI has
been able to quickly provide world-class DSL solutions to carriers in
Japan," said Hideo Takahashi, vice president of Business Development,
Sumitomo Electric U.S.A., Inc. "The relationship we have with
Centillium has helped us build a strong position in the DSL market in
Japan and throughout the world."
The CU4000 series features full support for international
standards of ADSL, including G.lite (Annex C), full rate and
symmetrical DSL for Japan (Annex C and H), the United States (Annex
A), and throughout the world (Annex A). Centillium's CopperFlite
chipset features support for all these standards, making the unique
technical functions available for SEI's leading edge equipment
"We're thrilled to continue this strong relationship with SEI by
providing full rate Annex C and Annex H ADSL chipsets for the CU4000
platform," said Dori Braun, vice president, Access Business Unit,
Centillium Communications, Inc. "Japan's ADSL market is strong, and we
look forward to continuing to support SEI in their market leadership
into the future."
