TranSwitch Corporation’s Atlanta 2000 Processor Supports “High Definition Voice” for the Japanese Market

TranSwitch® Corporation (NASDAQ: TXCC), a leading provider of semiconductor solutions for the converging voice, data and video network, today announced that its Atlanta™ 2000 communications processor product family will support Wideband Voice functionality which is a key requirement specified by Japan’s telecommunications service providers. Wideband voice, also known as high definition (HD) voice, provides deeper clarity and a better audio experience than today’s telephone network. Service providers worldwide are in the process of modernizing their networks from legacy circuit-switched infrastructure to packet-switched technology capable of delivering voice, video and data services. These networks use voice-over-IP (VoIP) technology, which includes capability for wideband voice.

Atlanta 2000 supports up to four channels of wideband voice conforming to an International Telecommunications Union’s (ITU) G.711.1 specification which is has been selected for deployment in Japan. Because of its unique architecture and powerful processing capabilities, Atlanta 2000 can simultaneously support two Gigabit, wire-speed router functionality under short-packet (i.e. worst case) traffic conditions and four wideband voice channels without deterioration of either the voice quality or the data performance. This remarkable achievement is a result of Atlanta 2000’s unique architecture which integrates two RISC cores with a DSP and off-loads voice processing from the RISC cores to the DSP. With this architecture, all of the power associated with Atlanta 2000’s triple issue, Xtensa LX2 processors can be focused on routing packets and generating high ‘caffeine score’ Java benchmarking scores, resulting in best-in-class performance.

“TranSwitch is pleased to announce our support of the G.711.1 wideband codec standard on the Atlanta 2000 platform” said William McDonald, Director of Marketing at TranSwitch Corporation. TranSwitch’s support of this codec confirms our continuing commitment to the Japanese market. Our long tradition of close collaboration with leading equipment suppliers and network operators in Japan began with the introduction of our Palladia and Maximus ADSL2++ modem chip products as the former Centillium corporation. Our Mustang GEPON ONU chip products currently play a major role in Japan’s fiber-to-the-home deployment initiative. Our Atlanta 2000 communications processor is designed to meet or exceed the demanding requirements of the Japanese market, and is ideally suited for next generation network (NGN) home gateway and small-medium business (SMB) router applications of the Japanese market.”
