Centillium Chipset Delivers 256 Compressed Voice Channels Over Packet Network

FREMONT, Calif., May 17, 2000 –
Centillium Communications, Inc. announced its entry into the Voice-over-Packet market with a new chipset solution for compressing and processing high-capacity voice services over packet-based networks, initially starting with voice-over-ATM (VoATM). Alcatel (NYSE:ALA) selected Centillium's Entropia solution for a new integrated voice gateway in Alcatel's Litespan family of multiservice access platforms. The Entropia-based service card will allow network service providers to merge voice and data traffic onto one network and offer new services to customers.

"Entropia supports higher density than others in the industry and gives us the versatility we need to offer integrated voice and data to our customers," said Hamid Lalani, Vice President of Marketing for Alcatel's Wireline Access Division.

Centillium's Entropia chipset is a complete system solution that includes a communications digital signal processor (DSP), software for voice processing including compression, echo cancellation, ATM adaptation layer processing, and host API software. The Entropia chipset replaces the current practice of using general-purpose DSPs (capable of processing only 12 channels of voice) with a high-capacity system-on-a-chip solution that increases the voice processing by a factor of 20.
