Spirent Selected as the First Supplier of Test & Measurement Solutions for Alcatel-Lucent's Industry Leading IP Transformation Center

SUNNYVALE, Calif. -- Spirent Communications plc (LSE: SPT), a global provider of performance analysis and service management solutions, today announced that it signed a formal partnership agreement with Alcatel-Lucent (ALU) to provide Triple Play testing solutions that enhance operations of Alcatel-Lucent's global IP Transformation Center (IPTC). The IPTC is the industry's only state-of-the-art operation dedicated to the advancement of triple play, IPTV, IMS and FMC deployment projects across the globe.

Alcatel-Lucent's IPTC develops, integrates, tests and conforms end-to-end IP networking solutions towards sustained KPI's and KQI's. This helps operators and enterprises, faced with a highly competitive environment, to transform their networks to a full IP-based architecture. Through this partnership, Alcatel-Lucent and Spirent help advance the interoperability of collaborative IP networking solutions up to end to end service delivery.

"Shortening the IP transformation period and ensuring seamless customer network migration is the prime objective of our global IP Transformation Center," said H. Derrey, vice president of Network Integration & Convergence - Wireline at Alcatel-Lucent. "Spirent's triple play and IPTV testing solutions coupled with its professional services expertise make it an ideal partner to help us meet the challenges of next generation networks and the requirements of the IPTC."

Alcatel-Lucent's IPTC recently deployed Spirent TestCenter[TM] along with the Spirent TestCenter GUI, which easily converts test cases into automated scripts for around-the-clock testing. Alcatel-Lucent also uses Spirent TestCenter with the L4-7 Triple Play bundled solutions to test with real H.264 video, real voice using SIP, and real application data.

"The Alcatel-Lucent IPTC was developed as a showcase for Next Generation Network (NGN) and IP transformation technologies and services and plays an important role in the development efforts for both Alcatel-Lucent and Spirent," said Rob Piconi, president and chief operating officer of Spirent Communications. "This new partnership is a very positive step for Spirent TestCenter and we are pleased to be a formal partner in what is proving to be an accelerator for seamless network transformation in our industry."

Spirent TestCenter delivers significant improvements in testing productivity during every stage of product development and service creation to accelerate time to market and reduce operational and capital expenses. The new platform was built on the all-new Inspire Architecture[TM] in response to the market's growing demand for a test system that improves time to market and reduces product development costs while ensuring the highest subscriber quality of experience (QoE).
