For Immediate Release: April 24, 2017

Key Takeaways:

  • The latest Sonus SBC Core portfolio software release offers a secure and scalable NNI solution that is verified to be compliant to TTC interworking standards commonly used within Japan.
  • Sonus solutions provide complete network protection from theft of service and other SIP-based attacks during interconnection.
  • The Sonus SBC Core portfolio is available in appliance or Cloud native deployments, providing a seamless path from hardware to the Cloud.

WESTFORD, Mass. – Sonus Networks, Inc. (NASDAQ:SONS, news, filings), a global leader in securing Cloud and real-time communications, announced today the latest Sonus SBC Core portfolio software release with support for IP interface for network-to-network interconnection standards commonly used within Japan and the greater APAC region. This functionality helps Japanese and other APAC carriers meet strict Telecommunication Technology Committee (TTC) interconnection requirements at a lower cost, while providing a high-quality and secure experience to subscribers.

As service providers migrate from legacy infrastructure to next-generation Session Initiation Protocol (SIP)-based networks, the need to interconnect with partner networks for coverage and cost reasons becomes increasingly important. However, carriers must overcome unique performance, security and routing challenges when connecting high volumes of traffic. Sonus has partnered closely with key tier-1 customers to develop and verify that its solution is compliant with Japanese Network-to-Network Interfaces (NNI) standards.

Performance at Scale

The Sonus SBC 7000 is architected to scale up to 150,000 sessions in a single system with onboard DSPs for transcoding. This scalability simplifies and consolidates the DNS and IP peering configurations on NNI. Additionally, the Sonus SBC Core portfolio provides built-in Least Cost Routing, Local Number Portability and multimedia routing to simplify network management and reduce costs.

Robust Network Security

With advanced encryption and Denial of Service capabilities, the Sonus SBC Core portfolio provides security that scales as interconnection points grow. This functionality provides protection for the carriers’ core as well as partner networks from attacks.

Seamless Path to Virtualization

To future-proof interconnection investments, the Sonus SBC Software Edition (SBC SWe) uses the same management and software interface as the hardware-based Sonus SBC 5000 Series and Sonus SBC 7000. This provides carriers with the ability to choose hardware for interconnection today and seamlessly migrate to virtualization and the Cloud in the future without additional investments in training and equipment.


“The Sonus SBC Core portfolio is trusted to deliver high volumes of reliable and secure real-time communications in some of the world’s most demanding networks today,” said Shambhu Rai, Principal Product Manager, Sonus. “With the Japan specific NNI functionality, Sonus shows its dedication to the Japan and APAC markets, enabling standards-based secure and cost effective network-to-network interconnect among operators. This will not only reduce the cost of interconnect, but also reduce the time and effort spent by operators to setup interconnect services.”

Other Facts:

  • The Sonus SBC Core portfolio consists of the hardware-based SBC 5000 Series, the SBC 7000 and SBC SWe.
  • The full Sonus SBC portfolio was recognized as a winner of the 2016 Network Security Excellence Award presented by TMCnet.
