Dual-core communications DSP for HD voice applications

TranSwitch's new Atlanta 2000 DSP communications processor supports the Wideband Voice functionality.

Large bandwidth voice, also known as high definition (HD) voice, provides extreme clarity with a better audio experience when compared the present telephone network. Now the service providers are modernizing their networks from circuit-switched infrastructure to packet-switched technology that has the capability of delivering voice, video and data services. These networks use voice-over-IP (VoIP) technology, which includes capability for wideband voice.

Atlanta 2000 processor supports 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, and it achieves a unique architecture which integrates two RISC cores with a DSP and off-loads voice processing from the RISC cores to the DSP.

"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. Tran Switch'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."
