Japanese company releases new innovative VoIP switch
Japanese enterprise OKI has announced about provisional expansion of he functionality of the application CenterStage NX3200, its corporate level session border controller (SBC), designed for interconnectivity among other fixed KDDI VoIP network carriers. First such product was first delivered to KDDI one year ago, as the response to the impending depletion of IPv4 addresses.
KDDI ensures the interconnection of fixed VoIP networks. In order to achieve successful interconnections with other carriers, it has to integrate all the SIP associated differences smoothly while securing connectivity with different end-points and services. Additionally, it has to provide reliable, high-quality voice communications. OKI's NX3200 fulfills all these quite stringent requirements and it has been chosen as a subsequent SBC to interconnect with other KDDI VoIP network carriers. 'NX3200 offers broad spectrum session control functionality growing up to a maximum of more than 40,000 simultaneous connected sessions, ensuring the procedures on ATCA and the CenterStage HAPF platform, as well as an industry-leading accessibility of nearly 100% annual operational rates (OKI-measured value),' stated Hidetoshi Saigou, General Manager of Info-telecom Systems Division at OKI. 'Moreover it delivers the flexibility needed to embed future functional upgrades, including voice/video codec conversion functions, while achieving low-delay, high-speed transmission performance equivalent to wire rates, as well as high level of robustness. It's also fully capable of providing functionality in the timely manner required to achieve FMBC, one of KDDI's goals.' OKI will proactively develop and provide technology for next-generation carrier-grade networks that meet the needs of telecommunication carriers. 'The NX3200 is taking extremely important niche in matters of maintaining the high reliability and quality of KDDI's fixed VoIP network and gets extremely scalable interconnectivity among carriers,' add Toshihiko Yumoto, Network Technical Development Division 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 KDDI's VoIP services.' CenterStage NX 3200: Main characteristics Functions absorbing SIP differences allow for flexible interconnections The NX3200's SIP interwork operation Config function and its SIP signal screening function help achieve flexible interconnections without reworking software. High (99.9999%) availability for carrier-grade performance The NX3200 incorporates OKI's unique high-performance, Linux-based CenterStage HAPF firmware to achieve communications control and operational functionality. Versatile customization The NX3200 allows rapid configuring for the specific desires of any customer since most functions, including the SIP stack, are OKI-developed. NX3200 is the fully compatible with maintenance operation functions (test, monitoring, traffic control functions) that draw on OKI's years of cumulative expertise in switching technologies. IP address conversions for SIP signals The NX3200 achieves interconnections through IPv4-IPv6 conversion functions. High throughput and low-delay IP conversion and addressing The NX3200 allows IPv4-IPv6 interconnections with high throughput and low delay, built on NA(P)T-PT IP protocol conversion and NA(P)T IP address conversion functions.
