Centillium's Plug-and-Play USB Chipset Solution  
Enables Carriers in Japan's Accelerating DSL Market  
To Deploy Quickly and Cost Effectively  
Centillium Communications, Inc. (Nasdaq:CTLM), innovator of 
broadband communications technology, today announced a partnership 
with Sumitomo Electric Industries (SEI) to provide a high-performance 
customer premises equipment (CPE) solution to the Japanese market. 
SEI, a total solutions provider in broadband networking, will 
integrate Centillium's high-performance, Universal Optimizer(TM) USB 
chipset solution into its CPE equipment. This USB chipset solution, 
which supports both Annex A and C, alleviates global deployment issues 
while meeting the explosive demand for DSL in Japan.  
"This is a very exciting time for SEI," stated Hideo Takahashi, 
vice president of Business Development, Sumitomo Electric U.S.A., Inc. 
"Unlike the rest of the world, Japan's existing telephone network uses 
TCM-ISDN, and therefore requires special DSL solutions like those 
provided by Centillium. We believe our customers will be delighted 
with the consumer-deployable offering they will receive with 
Centillium's advanced CPE solution. Together, Centillium and SEI will 
take the Japanese DSL market to a new level."  
Centillium's USB chipset solution demonstrates the company's 
continued commitment to satisfying the needs of Japan's unique DSL 
market. SEI has chosen Centillium's Universal Optimizer for its 
highest throughput performance, and ease-of-use characteristics. The 
Universal Optimizer is fully compliant with all industry standards, 
including USB v1.1, making the technology fully interoperable.  
"Centillium is excited to be working with SEI for this benchmark 
technology," stated Dori Braun, vice president of Marketing, access 
business unit for Centillium. "We have worked hard to ensure that our 
CPE solution is superior to others on the market providing the user 
with a cost-effective solution offering plug and play, easy 
installation and configuration process. SEI's proven leadership in the 
industry will allow for the continued growth and success of DSL 
deployment, making DSL a more cost-effective and attractive solution 
for not only consumers, but also small businesses."  
This partnership reinforces Centillium's leadership and aggressive 
approach in Japan's DSL market, which is another step in establishing 
a strong international presence. Centillium has been developing 
solutions for Japan's DSL market since 1997. By partnering with one of 
the most prominent equipment providers in the world, Centillium will 
continue to deliver its external USB and external routers to ensure 
the Japanese market has a superior option for their networking needs.
