(Nasdaq: SONS), a market leader in next-generation IP-based network solutions, today announced that Peerless Network, a service provider that simplifies interconnection of voice, data and signaling across disparate networks, has purchased the Sonus NBS5200™ Network Border Switch to expand the capacity of its IP peering aggregation points.

Built on Sonus's new ConnexIP™ platform, the NBS5200 represents the next generation in border control with unmatched functionality. It is the highest-density, highest-scalability Session Border Control (SBC) solution in its class with integrated transcoding and media interworking as well as native support for IPv6 and IPSec encryption.  

Peerless Network added the NBS5200 to its existing NBS9000™ deployment because of the product's scalability and network capacity performance as well as its minimal footprint requirements in the data center. Peerless Network has experienced tremendous growth in IP traffic and selected the NBS5200 based upon its industry-leading performance, on-board transcoding, and network integration characteristics. With the ConnexIP platform, it provides high-performance network services in an extremely compact footprint that reduces operations and data center costs.

"We have completed our certification process on the NBS5200 and are very pleased with its overall functionality and performance results," said Jim Brewer, Vice President of Voice Services for Peerless Network. "We look forward to meeting the requirements of our rapidly expanding customer base and service portfolio with the deployment of this strategic IP platform at Peerless."

Independent testing firm Miercom Labs recently evaluated the NBS5200 and awarded the session border controller its Performance Verified Certification. Miercom's extensive testing concluded that Sonus's NBS5200 delivers extraordinary performance even under the most adverse conditions where other products often exhibit significant performance breakdown.

The NBS5200 enables Sonus to address the broadest set of SBC deployments in the market for service providers and enterprises. It has created strong customer interest since its introduction. In addition to its current customers, the NBS5200 is in trials and evaluations at multiple other locations.

"The NBS5200 will help Peerless Network to leverage its existing Sonus network and pave the way to handle future demands," said Guru Pai, executive vice president and chief operating officer for Sonus.  "Their decision demonstrates the market demand for a high session scale, transcoding dense-session, border controller solution. With it, they save on capital and operational expenses, which increases their return on IP infrastructure investments and makes the deployment more flexible."
