CENTILLIUM COMMUNICATIONS AND MEDIALINCS PARTNER TO BRING FULL RATE ADSL TO SUBSCRIBERS IN KOREA

Medialincs Selects Centillium's Central Office and Customer Premise Equipment Chipsets For High-Density, Low-Power, Full Rate ADSL Equipment

FREMONT, Calif., July 31, 2000 - Centillium Communications, Inc. (Nasdaq:CTLM), innovator of broadband communications technology, and Medialincs, a rapidly growing networking systems vendor, today announced a partnership aimed at increasing the deployment of Full Rate Asymmetric Digital Subscriber Line (ADSL) services in Korea.

Medialincs will design and manufacture Full Rate ADSL equipment based on Centillium's quad-port CopperFlite Central Office (CO) and USB-powered Flite Optimizer Central Premise Equipment (CPE) chipsets, which feature the highest level of port density and lowest power usage currently available on the market. This networking equipment will enable Full Rate ADSL deployments in multi-subscriber environments such as commercial multi-tenant units (MTUs), residential multi-dwelling units (MDUs), office parks, and campus-style settings.

"The receptivity to ADSL in the Korean market has been overwhelmingly strong," said Kimberly Funasaki, Senior Research Analyst, IDC. "The MTU/MDU market is a natural fit for this densely populated region, and the combined efforts of Centillium Communications and Medialincs will help service providers to profitably bring full-rate ADSL services to fruition in this environment."

"We evaluated all of the high-performance Full-Rate ADSL solutions available, and we chose Centillium's CopperFlite and Flite Optimizer chipsets because they have the highest levels of integration and density, as well as the lowest power consumption and bill of materials cost," said C.Y. Park, product manager of ADSL, Medialincs. "CopperFlite allowed us to design Full-Rate ADSL communications equipment that can meet the very restrictive facility requirements typically found in multi-tenant subscriber environments. These include low power consumption, low heat dissipation, and, most importantly, small size. Centillium's Flite Optimizer USB platform eliminates residential deployment challenges due to its ease of system installation and elimination of an external power supply."

"We are very pleased to partner with Medialincs, the fastest growing and most aggressive DSL equipment vendor in Korea," said Al Gharakhanian, director of marketing for network access products, Centillium Communications. "The highly integrated Centillium chipsets are ideal for Medialincs' clustered subscriber applications, such as residential multi-dwelling units, where there is no room for wasted real estate, power consumption, or cost."
