CENTILLIUM COMMUNICATIONS SHIPS 20 MILLION DSL PORTS IN FOUR YEARS

Company focus on technical innovation and customer commitment across multiple market segments enables rapid achievement of key industry milestone

FREMONT, Calif., November 17, 2003 -

Centillium Communications, Inc. (Nasdaq: CTLM), innovator of broadband communications technology, today announced that it has shipped in excess of 20 million ports in less than four years. Continuing its growth in the burgeoning Digital Subscriber Line (DSL) market, Centillium's ability to innovate ADSL technology coupled with its unwavering commitment to serving the customer's needs has made it a major supplier of central office (CO) and customer premises equipment (CPE) chipsets to manufacturers around the world.

Centillium reached the 20 million-port milestone in a relatively short-time frame, but the market for new DSL subscribers still exhibits signs of robust growth. At the end of the second quarter of 2003, there were 45 million active ADSL lines in service globally with each active ADSL line requiring both a CO and a CPE port, according to market research firm Dell'Oro Group. The firm predicts that the worldwide ADSL market will grow to more than 78 million lines by fourth quarter 2004.

"To have shipped in excess of 20 million ports in just four years shows Centillium's ability to turn an idea – ultra-fast broadband access – into an innovative product line while meeting the needs of the customer," said Tony Shakib, General Manager for Centillium’s Access & Networking Business Unit. "We anticipate further DSL subscriber growth, especially in the fast-growing regions of China, Japan and Europe. We expect Centillium's technology will enable the deployment of exciting new broadband services such as up to 50 Mbps in downstream data rates, video on demand, voice over DSL and extended distances to reach more subscribers than ever."

Centillium is well positioned to participate in the growth of DSL in markets such as China, Japan and Europe by continuing its track record of bringing successful innovations to market as a leader in the industry. Centillium's Maximus CO and Palladia 220 CPE chipsets are the first in the industry to produce downstream data rates of up to 50 Mbps and the first to extend the reach of ADSL up to 22,000 feet from the central offices. Centillium was also the first company on the market to introduce ADSL CPE chipsets capable of downstream data rates of up to 24 Mbps and the first company to introduce ADSL chipsets capable of up to 12 Mbps. In addition Centillium was the first company to introduce the multiple channel CO line card and the first to introduce chip sets for Annex C in Japan as well as many other innovations.

Centillium's track record for introducing innovations comes from the company's commitment to listen to the needs of customers and its devotion to working side-by-side with those customers to introduce the technology that they require to remain competitive.
