Legerity and Mindspeed Introduce the Industry's First 48-Channel VoIP Reference Solution with Integrated Line Testing.

SAN JOSE, Calif. -- Legerity, Inc., the "V" in VoIP(TM) and Mindspeed Technologies, Inc. (NASDAQ:MSPD), a leading supplier of semiconductor solutions for network infrastructure applications, today announced at Spring VON 2006 a reference and evaluation platform which demonstrates complete system-level voice-over-IP (VoIP) processing for 48 standard telephone lines within an IP Multimedia System (IMS) infrastructure. The reference design will accelerate product design for access equipment vendors developing carrier-grade plain old telephone service (POTS) capabilities on an Ethernet/IP-based access network.

The system, focused on Multi-Service Access Platform (MSAP) and remote fiber-to-the-curb (FTTC) infrastructure equipment, is built around Mindspeed's Comcerto(TM) 500 family of VoIP processors, and Legerity's Voice Edge 790 family of narrowband copper loop termination devices.

The Mindspeed(R) programmable Comcerto VoIP devices integrate digital signal processing, packet processing, signaling, call control and system management, and are available in footprint-compatible versions supporting 4 to 128 VoIP ports. Mindspeed's production-quality voice processing software completes the full-featured offering. Legerity's Ve790 devices provide long-loop, high performance telephone loop termination capabilities, including the industry's most robust, accurate, and feature-rich line testing functions. This automated, remote line testing allows network operators to monitor, diagnose, and pinpoint potential problems, all before involving service technicians, or affecting customers. The entire system can be configured to different standards worldwide, due to the software-programmable nature of both product families.

"The tight collaboration between Mindspeed and Legerity resulted in a solution that will significantly reduce our joint customer's time to market," said Jacques Issa, senior director of marketing and applications at Legerity. "Moreover, the innovation presented in this partnership is setting the standard for the industry. This platform is not only the first true 48 channel solution, but also the first reference platform that shows full functionality from Ethernet packets to copper loops with integrated line-test diagnostic capability."

"Telephone customers expect the phone to work, even when the power fails. This 'lifeline' service is what the carrier telephone network provides, and what the networks of tomorrow must continue to provide. This system demonstrates that there is no need to sacrifice this lifeline or the carrier-class quality that we expect from our wired phones as we move to the advanced IP-based networks and services of the future," said Kurt Michel, director of product marketing at Mindspeed.

Legerity and Mindspeed will be showcasing reference design demonstrations this week at the VON Spring 2006 tradeshow in San Jose, the industry event for VoIP.
