VoIP Forum

today announced it has expanded the functionality of the CenterStage^® NX3200, its carrier-grade session border controller (SBC),¹to interconnect with other fixed KDDI VoIP services network carriers demanding high reliability and quality. The SBC was first delivered to KDDI in September 2010 in response to the impending depletion of IPv4 addresses.

As demonstrated by the functionality accommodating existing facilities, we have the highest regard for the NX3200, as a product that satisfies both reliability and expandability requirements. It will contribute to KDDIs VoIP services.

KDDI promotes the interconnection of fixed VoIP services networks. To achieve successful interconnections with other carriers, it must absorb the SIP² differences flexibly while securing connectivity with various terminals and services. Moreover, it must provide reliable, high-quality voice communications. OKIs NX3200 meets these stringent requirements and it has been selected as a subsequent SBC to interconnect with other KDDI VoIP services network carriers.

NX3200 offers large-scale session control functionality reaching up to a maximum of 40,000 simultaneous connected sessions,³ capitalizing on ATCA⁴ and the CenterStage HAPF⁵ platform, as well as an industry-leading availability of 99.9999% annual operational rates (OKI-measured value), says Hidetoshi Saigou, General Manager of Info-telecom Systems Division at OKI. It also offers the flexibility needed to accommodate future functional upgrades, including voice/video codec conversion functions, while achieving low-delay, high-speed transmission performance equivalent to wire rates,⁶ as well as high reliability. Its also fully capable of providing functionality in the timely manner required to achieve FMBC,⁷ one of KDDIs goals.

OKI will proactively develop and provide technology for next-generation carrier-grade networks that meet the needs of telecommunication carriers.

The NX3200 plays an important roleit maintains the high reliability and quality of KDDIs fixed VoIP services network and achieves interconnectivity among carriers, says Toshihiko Yumoto, General Manager, Network Technical Development Division, Technology Sector at KDDI. As demonstrated by the functionality accommodating existing facilities, we have the highest regard for the NX3200, as a product that satisfies both reliability and expandability requirements. It will contribute to KDDIs VoIP services.
