Spirent Solutions Enable Alcatel's IPTV Service Assurance Proof of Concept Lab

SUNNYVALE, Calif. -- Spirent Communications (NYSE:SPM) (LSE:SPT), a global provider of performance analysis and service management solutions, today announced its participation in Alcatel's IP Video Service Assurance Proof of Concept Lab. This trial lab is hosted by Alcatel to accelerate end-to-end test and measurement solutions for triple play service offerings.

Spirent's world-class test and measurement solutions have been chosen by Alcatel to create an end-to-end solution for IP-based video service offerings. Spirent's SmartSight, IPMax, video performance management and Tech-X solutions are proven service assurance tools for IPTV and triple play. To date, Spirent offers the only solutions available that emulate the subscriber experience through the transport core, access and in the home. Spirent's solutions are used by the NOC and operations service center to quickly and easily diagnose complex IP service impairments.

Spirent's Video Test Solution (VTS) will give the Alcatel lab the capability to do in-depth analysis of video quality via a lab-based test bed. This innovative platform provides IP impairment emulation and video quality assessment for thorough evaluation of device and network performance.

"Spirent's contributions to the Alcatel IPTV ecosystem will help accelerate IPTV deployment," says Jeff Schmitz, vice president of product marketing at Spirent Communications. "The data collected during the lab's operation will offer a pre-deployment analysis of real-world subscriber experiences. By verifying service quality and the subscriber experience prior to launch, operators gain an understanding of what it takes to deliver IPTV right the first time."

The Alcatel IPTV POC Lab was unveiled at the Telco TV Conference & Expo, held in Dallas, TX, Nov 6-8, 2006. This landmark event will push the envelope of IP video service delivery and will accelerate the deployment of FTTn triple play and IPTV deliver service.
