TranSwitch Corporation Expands EtherMap Family to Enable Dynamic GigE and SAN Data Transport Services for SONET/SDH MANs.Business/Technology Editors SHELTON, Conn.--(BUSINESS WIRE)--May 28, 2002 TranSwitch Corporation (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on : TXCC TXCC Transwitch Corporation (stock symbol) ): EtherMap(TM)-48 improves provisioning of Ethernet traffic enabling Service Providers to add new revenue generating services over existing infrastructure 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 See add/drop multiplexer. (language) ADM - A picture query language, extension of Sequel2. ["An Image-Oriented Database System", Y. Takao et al, in Database Techniques for Pictorial Applications, A. Blaser ed, pp. 527-538]. ) 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 VLSI: see integrated circuit.

This allows mapping of variable length, higher-layer client signals over a transport network like SDH/SONET. The client signals can be protocol data unit (PDU) oriented (like IP/PPP or Ethernet Media Access Control) or can (GFP GFP Green Fluorescent Protein GFP Generic Framing Procedure GFP Government Furnished Property GFP Generic Frame Protocol GFP General Framing Procedure GFP Global Functional Plane GFP Global Field Power GFP Grandmothers for Peace GFP Glutton for Punishment ) or Link Access Procedure for SDH (Synchronous Digital Hierarchy) The European counterpart to SONET.

TranSwitch's EtherMap-48 blends exceptional SONET/SDH processing capabilities with optimized Ethernet payload transport to support interfaces comprised of up to four ports of Gigabit Ethernet and up to 24 ports of Fast Ethernet traffic. Mapping of block-encoded clients for SAN applications is also provided to support up to four 8B/10B encoded GigE, Fibre Channel or ESCON (Enterprise Systems CONnection) An IBM S/390 fiber-optic channel that transfers 17 Mbytes/sec over distances up to 60 km depending on connection type.

"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. Current implementations for combining SONET/SDH framing, Ethernet MACs, EoS mapping and path switching requires multiple discrete devices, including FPGAs and development of extensive management software in proprietary implementations. The EtherMap-48 greatly simplifies this approach by consolidating and optimizing these functions using an embedded RISC processor. The RISC-core and software suite permit outstanding data collection capabilities, thus alleviating the need for detailed device register manipulation. The EtherMap-48 incorporates additional functions for SONET/SDH framing, overhead and pointer processing and embedded RISC RISC in full Reduced Instruction Set Computing Computer architecture that uses a limited number of instructions. RISC became popular in microprocessors in the 1980s. intelligence into a single device for EoS mapping. EtherMap-48 also supports SAN data transport through transparent mode Generic Framing Procedure (GFP) for block-encoded client traffic in addition to the more commonly used GFP framed mode. This expands the application range for using the SONET/SDH infrastructure to transport a variety of data types. By incorporating GigE MACs (Media Access Controllers) with flow control, the EtherMap-48 supports over-subscription of Ethernet streams. In addition, the EtherMap-48 handles traffic using either standard or virtual concatenation and can optionally function in Link Capacity Adjustment Scheme Link Capacity Adjustment Scheme or LCAS is a method to dynamically increase or decrease the bandwidth of virtual concatenated containers. The LCAS protocol is specified in ITU-T G.7042. (LCAS LCAS Link Capacity Adjustment Scheme (SDH/SONET Virtual Concatenation) LCAS Lake County Astronomical Society (Illinois) LCAS Licensed Clinical Addictions Specialist ) mode for hitless rate adaptation to dynamically alter bandwidth capacity. The device supports multiple configurations of Virtual Concatenation Groups (VCGs) to support customer requirements. In response to network conditions such as path segment failures or periods of bursty LAN/SAN traffic, service providers can better manage and deploy customer-allocated bandwidth to achieve more efficient metro ring utilization. The EtherMap-48 allows for compensation of up to 50ms of differential delay during alignment of VCGs. To achieve this, a glueless SDRAM (Synchronous DRAM) A type of dynamic RAM (DRAM) memory chip that has been widely used since the late 1990s. SDRAM chips eliminated wait states by dividing the chip into two cell blocks and interleaving data between them. controller interface that requires no external timing or logic is provided for easy implementation. SONET/SDH payloads may be groomed or looped back using dual high/low order STS-1/VC-3 level cross-connects, which preserves any contiguous concatenation group and allow the path flow to be provisioned to best satisfy the application requirements. The EtherMap-48 has been designed to work seamlessly with commercially available Ethernet and SAN switching components to enable comprehensive designs for carrier class applications. The EtherMap-48 cost-effectively bridges the gap between SONET/SDH and Ethernet LANs, permitting transparent full or fractional Ethernet transport. "Service providers are delayed in the execution of native Optical Ethernet initiatives, while at the same time have chosen to continue with SONET/SDH in the short-term for stepping up their Ethernet WAN deployments. EoS technology augments the continuing notion of SONET/SDH as the primary WAN backbone layer that can generate additional immediate revenue. This is especially true for VDSL See DSL.
