WESTFORD, Mass. -- Sonus Networks, Inc. (Nasdaq: SONS - News), a leading supplier of service provider IP-voice infrastructure solutions, today announced that XO Communications, has upgraded its network security by deploying Sonus' field-proven Network Border Switch (NBS). Unlike traditional peering and security products such as Session Border Controllers (SBCs), Sonus' NBS is a purpose-built IP-based solution that combines session control, PSTN gateway services and security into a single, high performance, highly scalable, carrier-class solution. The power of the NBS to protect IP-voice networks was recently validated by CT Labs, a full service testing and analysis lab, which concluded after a battery of tests that the NBS is capable of standing up to extreme denial of service attacks.

"XO is committed to providing its business customers with premium voice service, and in today's environment, that requires defending the network against a variety of security threats," said Randy Nicklas, chief technology officer, XO Communications. "In addition, more and more network operators are investing in their IP networks. With the NBS, we're able to peer directly with other networks via IP. The transcoding capabilities of the NBS have enabled us to broaden our service offerings and to drive even greater efficiency throughout our network."

The Sonus Network Border Switch is architecturally designed to improve connectivity between disparate IP networks and allow operators to gain protection, control and visibility over those accessing their networks. XO Communications has one of the United States' largest IP voice networks, carrying more than 15 billion minutes of IP voice traffic in 2006, and currently carrying approximately 1.6 billion minutes of IP voice traffic every month. With such a large IP voice deployment, scalability and reliability were two of the driving factors for migrating to the NBS.

"Like the entire Sonus product portfolio, the NBS stands out in the industry for its ability to scale while maintaining the highest levels of performance and reliability," said Hassan Ahmed, president, chairman and CEO, Sonus Networks. "We understand that security is a top concern for today's network operators, and we are committed to helping our customers protect the integrity of their networks, even under the most demanding environments."
