SHELTON, Conn. -- TranSwitch(R) Corporation (NASDAQ: TXCC), a leading provider of high-speed Broadband, Transport and Switching semiconductor solutions for voice, data and video communications, today announced availability of the EtherPHAST(TM)-24 dual OC-12 mapper-framer, a complementary member of the company's family of EtherMap(R) and EtherPHAST transport devices for Ethernet, SAN, TDM and packet clients. The EtherPHAST-24, which has been designed into a major OEM's platform, targets multi-service applications including full rate GigE and sub-rate SAN requirements in small to large MSPP/ADM/CWDM platforms where redundant OC-12 (622Mbs) mapping bandwidth is optimal, or where a single device supports two OC-12 ring interfaces. This device also has associated price performance advantages over more costly full rate OC-48 solutions.

EtherPHAST-24 complements TranSwitch's EtherPHAST-48 Plus full rate OC-48 EoS/SAN framer-mapper, and the EtherMap-12 and EtherMap-3 Pt lower rate OC-12 and OC-3 EoS mappers. The intelligent software API driver/firmware set and external interfaces used for the EtherPHAST-24 are identical to the EtherPHAST-48 Plus, allowing customers to leverage their software integration and board design across multiple projects with different bandwidth rates and interface requirements. Like the EtherPHAST-48 Plus, the EtherPHAST-24 features telecom bus expansion port and an internal cross-connect. Thus customers can design highly flexible and scalable system solutions utilizing a combination of EtherPHAST-24 and EtherMap-12 or EtherMap-3 devices to provide a rich mix of high order and low order mapping, cross connection and grooming for VCAT/LCAS applications.

"Equipment manufacturers can now implement appropriately dimensioned, cost-effective transport devices rather than force fit an oversized device that carries a penalty in terms of higher cost, power, interfaces and more bandwidth than is necessary," said Rob Schwaber, product marketing manager for TranSwitch. "With the EtherPHAST-24, for example, they can satisfy transport requirements today and migrate seamlessly to the OC-48 solution tomorrow, safeguarding their investments and resources.

"This makes sense," continued Schwaber, "considering the large number of pizza box/Micro MSPP designs being built for the broadband Customer Edge that efficiently share board designs in a product family with larger systems serving the Provider Edge networks."
