Telcordia Enables Number Portability for Centennial.

Contract Continues Telcordia's Worldwide Leadership in Wireless and Wireline Number Portability 

PISCATAWAY, N.J. -- Telcordia (www.telcordia.com), a leading provider of telecommunications software and services, has been selected by Syniverse Technologies (www.syniverse.com), a provider of mission-critical technology services, to support Syniverse's recent number portability agreement with Centennial Communications. The multi-year contract extends Telcordia's position as the leading provider of number portability services in North America, where it currently serves 95% of the wireline and wireless market.

At the core of the Syniverse-provided solution is the global market-leading Telcordia[R] Service Management Gateway for Wireless Number Portability, which will enable number portability for Centennial in the Midwest and Southeast United States, as well as Puerto Rico and the U.S. Virgin Islands. Centennial currently serves approximately 1.1 million wireless subscribers and 387,500 access lines and equivalents.

"With more than 120 service providers using Telcordia for their number portability deployments across 8 countries, Telcordia has become the company that Centennial and other service providers turn to when they want to give wireline and wireless users more freedom," said Rich Jacowleff, Senior Vice President, Telcordia. "Market-leading solutions such as the Telcordia[R] Number Portability Clearinghouse and Telcordia[R] Service Management Gateway for Wireless Number Portability give service providers the flexibility to meet government mandates and improve their competitive positions."

In May 2006, Telcordia and Syniverse extended and enhanced a multi-year contract, demonstrating Telcordia's market leadership in delivering business continuity and operational excellence. Almost all major service providers in North America use the combined solution for number portability.
