Business Editors/High-Tech Writers

AUSTIN, Texas--(BUSINESS WIRE)--Sept. 22, 2003

Legerity Inc. today reinforced its position as the dominant supplier of line interface solutions with the announcement of the Le5712 Dual SLIC device, the most cost-effective solution for Digital Loop Carrier (DLC) applications in India and North America. This newest addition to the VoiceEdge(tm) 580 chip set family further solidifies Legerity as the leader in low-priced, solid-state line interface solutions for the fastest-growing voice telephony market segments.

The Le5712 device is pin compatible with Legerity's Le5711 Dual SLIC product that targets low-cost carrier-class line cards for China as well as Private Branch Exchange (PBX) and Key Telephone System (KTS) equipment. Value-added features designed into the new Le5712 Dual SLIC include ground start, foreign fault detection and indication, pulse metering support and optional high longitudinal balance (better than -63dB).

Six of the world's largest telecom OEMs, centered in China, India and the United States, have adopted Legerity's Le5712 Dual SLIC for new line card designs. Legerity began shipping production units in August 2003 and expects to exceed 1 million lines shipped in the first quarter of 2004.

"Legerity's VoiceEdge chip set with the Le5712 is an essential element enabling UT Starcom to deliver a dense and economical system to major carriers in Asia, and the rest of our global markets," said Jerry Soloway, senior vice president of engineering for UT Starcom. "This translates into increased revenue and captured market share."

"The overwhelming popularity of the Le5712 for low-cost, basic line cards once again showcases Legerity as the market leader for carrier-class voice telephony line interface solutions," said Rick Beale, director of marketing for Legerity's Voice Network Access business. "The depth and breadth of our VoiceEdge product family provides equipment vendors tremendous design flexibility and reuse potential."

Packaged in a 44-pin eTQFP small footprint plastic package, the Le5712 is pinout and firmware backward compatible to the Le5711, enabling equipment vendors to design one line card platform for multiple applications and multiple countries. And by using Legerity's VoicePath(tm) software development tools and reference designs, equipment vendors can significantly shorten their time-to-market and drastically lower their system development costs.

The Le5712 Dual SLIC is a part of the VoiceEdge 580 chip set family, which includes the 58 Series 4 channel and 8 channel programmable SLAC devices, the 57 Series and 79 Series SLIC devices, and the small footprint Line Card Access Switch (LCAS) devices with single, double and triple two-Form-C switches in a single plastic package. Samples of the Le5712 device are currently available through the local Legerity sales offices. Pricing starts at less than $3.30 per unit ($1.65 per channel) in high volume production.
