TranSwitch (TXCC) and VoiceAge Partner to Accelerate Global Adoption of “High Definition Voice”

Feb. 16, 2010 (Business Wire) — TranSwitch® Corporation (NASDAQ: TXCC), a leading provider of semiconductor solutions for next-generation communications infrastructure and CPE solutions, and VoiceAge Corporation, a leading developer of voice codec technology, today announced that they are increasing their cooperation to accelerate the global adoption of high-definition (HD) voice in wire-line and wireless carrier networks. VoiceAge played a central role in inventing the adaptive-multi-rate wide-band (AMR-WB) coder-decoder (codec) adopted by 3GPP, the global consortium for the cellular industry, and the associated G.722.2 wide-band codec adopted by ITU-T, the international telecommunications standards organization.

“Mobile carriers are starting to roll out the AMR-WB codec in their networks, bringing excellent audio quality to their customers. Thanks to the superior compression technology of the AMR-WB codec, we can accommodate speech bandwidth of 50—7000 HZ, more than twice the bandwidth of telephone systems, resulting in clearer and more life-like voice quality. Leading semiconductor companies like TranSwitch play a key role in enabling the widespread adoption of these new codecs in mobile and wire-line carrier networks as well as enterprise and consumer premise equipment.” said Laurent Amar CEO of VoiceAge.

“We are delighted to be working with VoiceAge to bring these new codecs to market. AMR-WB is the only wide-band codec standardized for both wireless and wire-line applications and hence is the natural choice for delivery of HD-voice calls over the converged fixed-mobile network.” said Dr. Hoshang Mulla, Vice President of Marketing at TranSwitch. “The multi-rate adaptive capabilities of this codec along with its state-of-the-art compression technology guarantee the highest voice quality under a variety of real-world network scenarios. These qualities make WRA-WB ideally suited for universal adoption across wire-line and wireless networks”, he concluded.

TranSwitch provides a broad range of System-on-Chip (SoC) solutions equipped with powerful embedded digital signal processors and comprehensive, field proven application software suites.

The Entropia product line designed for high and medium capacity infrastructure applications, and Atlanta product family designed for customer premise applications are both HD-Voice ready, supporting efficient implementations of the AMR-WB/G722.2 codecs.

The Entropia and Atlanta product families are supplied with comprehensive field proven application software suites, enabling a high level of system integration and accelerating the customers’ time-to-market. “Entropia and Atlanta’s optimization of performance, power, footprint, and their accompanying software suites are unparalleled in the VoIP semiconductor industry.” said Dr. Majid Foodeei, Dir of Technical and Strategic Marketing at TranSwitch. “TranSwitch’s impressive list of Entropia and Atlanta customers and their service provider clients establish them as a leading provider of VoIP semiconductors. We value TranSwitch as an important collaborator in the promotion of our AMR-WB Technology to our mutual customers”, said Richard Romagnino of VoiceAge. “We look forward to working closely with VoiceAge whose founders have a remarkable track record of contributions towards most modern codecs. Our joint effort no doubt can play a role in bringing the benefits of HD-voice to end users”, said Dr. Majid Foodeei of TranSwitch.
