Zarlink Extends Industry Leadership With Voice Control Processor

- New processor delivers industry-leading voice functionality and diagnostic tools for high density access platforms while lowering cost of ownership for telecom equipment manufacturers

OTTAWA, CANADA--(Marketwire - April 24, 2008) - Zarlink Semiconductor Inc. (TSX:ZL)(NYSE:ZL) today introduced its second-generation Le79114 Voice Control Processor (VCP II). This latest product supports 64 simultaneous call control channels and meets the needs of multiservice access infrastructure equipment manufacturers by enhancing call processing and critical line-testing (LineCare™) capabilities. The Le79114 also supports all functionality of the widely deployed first-generation Le79112 VCP.

LineCare, Zarlink's carrier-grade line diagnostic software, runs on the voice control processor and is the industry's most extensive line test and self-test software package, exceeding the GR844 standard. Telecommunication carriers make use of LineCare to remotely monitor networked subscriber lines more cost-effectively by eliminating the need of expensive test-head equipment.

"The Le79114 improves call processing within the communications network," said Shahin Sadeghi, segment marketing manager at Zarlink. "Today's digital networks bring together voice, video and data, challenging the industry to improve the quality of service for each offering while reducing the solution cost and increasing density. The Le79114, in conjunction with the Zarlink VE790 SLIC-SLAC family, allows service providers to test and provision telephony lines at low cost, yet maintain carrier-grade quality."

Incumbent and new communications carriers worldwide are overhauling existing networks or deploying new equipment to accommodate an increasing consumer demand for voice, video and Internet services.

"The ability to remotely monitor, test and fix telecom infrastructure issues is a critical need for the expanding and changing communications network," said Mr.Xu Ming, Product General Manager, Network Division, ZTE Corporation, a global tier one telecom provider. "Zarlink's LineCare and voice processing solutions help us to provide the highest possible level of support for our customers as we deploy our products, while significantly reducing our time-to-market."

The Le79114 Voice Control Processor II (VCP II) with LineCare supports 64 simultaneously active voice channels and implements critical real-time call control with signaling and monitoring functions. As a standalone product, manufacturers can divide and optimize low level call control and monitoring that have strict real-time requirements from DSP-intensive processing elsewhere in the system. The VCP II is a fully software-programmable line interface supporting multiple country applications as well as all AC, DC, signaling parameters and data.

Availability and Additional Information

The Le79114 device is available in a 128-pin TQFP package and is now in production. For more information on Zarlink's Legerity product line, please visit www.legerity.com.
