OCTOBER 26, 2006 - Murray Hill, N.J. - Lucent Technologies (NYSE: LU) today announced that it successfully participated in the MultiService Forum´s global multi-vendor interoperability IP Multimedia System (IMS) trial.

The two-week event, completed today, was hosted by five leading carriers - British Telecom, KT, NTT, Verizon Communications, and Vodafone -- and involved interoperability among 26 vendors´ equipment in five laboratories around the world, including the interoperability laboratory at the University of New Hampshire.

Lucent provided equipment in Verizon´s Waltham, MA lab, the same lab where Lucent recently successfully completed a separate IMS trial with the service provider. Verizon conducted an extensive trial of Lucent´s comprehensive IMS solution, which could help Verizon deliver new IP based multimedia blended services over a variety of access technologies.

For its trial with Verizon and the global IMS interoperability event, Lucent supplied a range of TISPAN- and 3GPP-compliant elements from its IMS solution including the Lucent Session Manager, Lucent Service Broker, Lucent Unified Subscriber Data Server, Lucent SurePay® Real-time Rating and Charging Engine, Lucent Feature Server, Lucent Network Gateway, Lucent Signaling Gateway and Lucent Network Controller.

The MultiService Forum (MSF) is a global association of service providers, system suppliers and test equipment vendors committed to developing and promoting open architectures.

The MSF trial tested multi-vendor interoperability within the IMS service framework. The event trial validated the MSF Release 3 Implementation that supports the industry´s TISPAN and 3GPP IMS standards.

“The MSF´s interoperability trial is another key milestone for the deployment of the IMS service delivery architecture that is already being implemented by Lucent customers globally,” said Roger Heinz, vice president, Lucent Technologies Converged Core Solutions.

“Verizon´s trial demonstrated the ability of our market-leading IMS solution to deliver both consumer and business Voice over IP. Our technology, coupled with the skills of our Lucent Worldwide Services organization, could allow Verizon to meet emerging market needs that go beyond voice,” said Tom Moore, vice president of sales for Lucent Technologies.

IMS is an open, standards-based multimedia service architecture that brings together mobile and fixed IP services to enable anytime, anywhere access. In addition, IMS helps to create an environment in which more features can more easily be customized or added.

About GMI 2006
GMI 2006 will bring together dozens of carriers and vendors to test the interoperability of IMS-based infrastructure components in a real-world setting. Providing a test-bed for the full spectrum of hardware, processes and services needed to assemble an effective next-generation delivery platform, GMI 2006 is designed to validate MSF Release 3 Implementation Agreements covering a wide range of topics including roaming across multiple network types (including cellular and WiFi), QoS issues (including session border control and bandwidth management), and interoperability with 3GPP release 4.

Five of the world´s top carriers - BT, KT, NTT, Verizon and Vodafone and a world class test facility UNH-IOL - will host the event to provide world-class networked test facilities spanning 3 continents. Comprising a massive ´real network´ trial of the MSF IMS-compatible (IP Multimedia System) Release 3 architecture, this event is critically important to any carrier or vendor committed to building or implementing infrastructure elements compatible with IMS.
