SHELTON, Conn. -- TranSwitch Corporation (NASDAQ: TXCC) today announced EtherMap(TM)-48, the newest member of its EtherMap family of products for transporting Ethernet-over-SONET/SDH (EoS). The EtherMap-48 is a unique four-channel Gigabit Ethernet mapper with SONET/SDH framing and rich Add/Drop Multiplexer (ADM) functionality that will enable Original Equipment Manufacturers (OEMs) and service providers to offer new revenue generating services for existing SONET/SDH networks. This highly integrated mapping device is targeted toward carrier access platforms with flexible Ethernet provisioning capabilities in existing metro optical networks. Carriers will now be able to satisfy growing metro data applications cost effectively while avoiding the complexity associated with legacy data transport. Additionally, carriers will be able to take advantage of extensive SONET/SDH network management and protection capabilities. The EtherMap-48 VLSI device supports mapping of multiple Gigabit or Fast Ethernet traffic and Storage Area Network (SAN) data streams into the SONET/SDH transport network at OC-48/OC-12 rates using Generic Framing Procedure (GFP) or Link Access Procedure for SDH (LAPS). "The EtherMap-48's combination of EoS mapping and SONET/SDH transport will permit OEMs to more effectively satisfy emerging Gigabit WAN initiatives being launched by service providers by allowing them to build more cost-effective standards-based EoS features into their new or existing platforms. OEMs and service providers will be able to leverage the EtherMap-48's powerful features set and dramatically improve key areas of OEM platform design, namely cost, space, software integration and power," stated Robert Schwaber, TranSwitch's Product Marketing Manager for metro products.
