High performance, VoIP enabled Atlanta-80M processor provides core functionality in SK Telesys VoIP-DECT phone

SHELTON, CT – March 27, 2009 – TranSwitch® Corporation (NASDAQ: TXCC), a leading provider of semiconductor solutions for the converging voice, data and video network, today announced the deployment of its Atlanta communications processor in SK Broadband’s roll-out of its Broad&Fone Voice over IP (VoIP) service throughout South Korea. SK Broadband (Formerly Hanaro Telecom) is the fastest growing Broadband service provider in South Korea, serving approximately four million broadband subscribers.

TranSwitch’s Atlanta 80M communications processor provides the core functionality in the SK Telesys IF-100 Digital Enhanced Cordless Telecommunications (DECT) phone, the primary vehicle for delivering Broad&Fone service to residential, SoHo and small to medium-sized business customers throughout South Korea. The IF-100 VoIP-DECT phone is manufactured for SK-Telesys by INBRICS (formerly Navons).

Atlanta 80M System-on-Chip (SoC) was selected for SK Broadband because of its ability to deliver high performance and a high level of integration which results in the need for fewer external components and thus a lower equipment cost. The architecture of TranSwitch’s Atlanta SoC incorporates a dedicated digital signal processor ensuring that a high data throughput can be sustained under real network conditions without compromising voice quality.

“Our subscribers demand a VoIP-DECT phone with the best voice quality and the highest data throughput with NAT enabled, and we provide it to them in spades with the IF-100. TranSwitch’s integration of a high performance RISC processor with hardware-based packet acceleration and a DSP into an efficient, low-power SoC has enabled us to supply a best-in-class VoIP-DECT phone at a competitive price-point,” said Mr. Kim Han Su, Ph.D of SK Broadband.

Atlanta 80M is a member of the Atlanta communications processor family that supports VoIP scalability from one to four low bit rate voice channels from its on-chip DSP, wirespeed data throughput performance for small packets by virtue of its fast path packet acceleration hardware, and an integrated encryption engine. “We’re pleased to supply Atlanta 80M to SK Telesys for its new VoIP-DECT phone and to play a key role in SK Broadband’s Broad&Fone VoIP service roll-out,” said Kris Shankar, VP of Sales Marketing for TranSwitch Corporation. “Our Atlanta communications processors are based on field proven technology and designed specifically for demanding, high-volume field deployments such as this. Our Atlanta processor family is a scalable set of solutions that enable a wide range of innovative voice and data products such as the IF-100”, he concluded.
