OKI Adds Carrier-Grade Wideband Codec Conversion Function in CenterStage NX3200

OKI Electric Industry reportedly has become first in the industry to add a carrier-grade wideband codec conversion function to its session border controller (SBC) “CenterStage NX3200.”

 

Compatible with wideband codecs such as ITU-T G.711.1, the equipment can simultaneously transfer large amounts of data between voice and video codecs used in mobile and fixed networks.

 

Hidetoshi Saigou, general manager of Carriers Business Division at OKI (News - Alert) stressed that the new wideband codec function for fixed and mobile networks will allow telecom carriers to offer ubiquitous services to their customers.

 

OKI has decided to continue enhancing the CenterStage Series that incorporates solutions to telecom carrier needs. For the purpose, they will leverage OKI’s technologies in transmitting massive amounts of video, voice and data, and its carrier-grade hardware and software technologies for NGN.

 

Users can enjoy higher voice quality with G.711.1, a wideband codec that was standardized by the ITU-T in 2008. The codec can convey sound more accurately and can also interconnect with the previous G.711 standard. OKI has also identified a clear trend towards wideband compatibility in the field of codecs for mobile network.

 

Although wideband codecs enable better quality in voice as well as video and data, a structure is required to seamlessly hand over service among telecom carriers.

 

Telecom carriers thus require a large scale SBC to offer wideband for mobile and fixed networks, interconnect among telecom carriers, and seamlessly connect different voice and video codecs.

 

OKI became first in the industry to incorporate in its SBC, next-generation wideband codecs for mobile networks (AMR-WB and EVRC RevB), in addition to G.711.1 standard. This has enabled telecom carriers to successfully incorporate wideband codec.

 

The NX3200 not only enables conventional codec conversion but it also enables simultaneously communication among various voice and video codecs used in both mobile and fixed networks. OKI emphasize that the SBC is thus ideal for use as the NGN interconnection equipment required in the development of ubiquitous services.
