RtS,
here is the EXPANDED business description of TXCC
TranSwitch Corporation, established in April 1988, designs, develops, markets and supports highly integrated digital and mixed-signal (analog and digital) semiconductor system-on-a-chip solutions for building emerging networks for telecommunications and data communications applications. The Company's VLSI semiconductor devices provide core functionality for communications network equipment. TranSwitch provides high levels of functionality for broadband communication networks and implements value-added features.
The Company's four product lines consist of multi-protocol programmable, SONET/SDH, asynchronous/PDH, and ATM/IP products. TranSwitch believes that its chip-set approach and broad product coverage in all four-product lines position the Company as a "one-stop source" for broadband communications VLSI products. Network equipment vendors can mix and match the Company's VLSI devices to optimally configure a specific system. The Company's product lines can be combined to provide a cost-effective communication systems solution with increased functional integration and features while providing seamless integration of SONET/SDH, asynchronous/PDH and ATM/IP for broadband network applications.
In September 2001, the Company acquired privately held Onex Communications Corporation. Onex specializes in the development of integrated circuits that enable switching, routing and transmission of multiple types of voice and data traffic.
Multi-Protocol Programmable Products
The Company introduced three multi-protocol products in 1999 and one in 2000 and extended its product family to provide seamless integration of asynchronous/PDH, SONET/SDH and ATM/IP protocols on a single chip. The mix and match of protocols and higher level of service-related functionality in these products enables its telecommunications and data communications OEM vendors to develop multi-service systems for access and transport applications.
The Company's PHAST (Programmable High Performance ATM/PPP/TDM SONET/SDH Terminator) series of products target simultaneous mapping and transport of ATM/PPP and TDM services over fiber optic networks. The ASPEN (Access Systems Processing Engine) family of network processor products provides complete higher layer functionality for processing cell and/or packet services. ASPEN has three embedded specialized RISC processors, which can be configured by downloading different software, to function as cell engines, packet engines or high-speed copper access engines.
SONET/SDH Products
In the SONET/SDH area, the Company offers devices that provide a direct interface for fiber optic transmission in North America, Europe and Asia. The Company's mappers, which bridge the interconnections between SONET/SDH equipment and asynchronous equipment, allow DS-series and E-series transmission lines to be connected with SONET/SDH lines. In this way these mappers transparently transport asynchronous signals across the SONET/SDH network.
The Company's current SONET/SDH products are used to build access equipment, add/drop multiplexers, digital cross connects (DACS) and other telecommunication and data communications equipment. This equipment is configured for use in both domestic and international fiber-based public networks. The Company's SONET/SDH products have applications in customer premise equipment, such as routers and hubs and in central offices, adding integrated fiber optic transmission capability to telephone switches.
Asynchronous/PDH Products
The Company's asynchronous/PDH products provide high-bandwidth connections and are used to configure transmission equipment for use in the public network. This equipment is used to increase the capacity of the copper-based public network. The Company's asynchronous/PDH VLSI products also enable customer premise equipment (CPE), such as hubs and routers used in WANs and LANs, to access the public network for voice and data communications with similar products in other locations.
The Company's asynchronous/PDH products provide high levels of integration, as well as cost, power and performance benefits relative to discrete and competing integrated circuit solutions. The Company's asynchronous/PDH VLSI products include devices that provide solutions for DS-1 through DS-3 and E-1 through E-3 transmission lines. This product line includes line interfaces, multiplexers that combine multiple low-speed lines to form a higher speed line, as well as demultiplexers, which perform the reverse function. In addition, the Company offers framers, which are devices that identify the starting points of defined bit streams and enable systems to recognize the remaining bits.
ATM/IP Products
The Company's ATM/IP family of products targets the core elements of ATM/IP-based multi-service access multiplexer systems. The Company's CellBus is a system architecture for implementing ATM/IP access multiplexers and ATM/IP switching systems. The Company's first two products incorporating CellBus, CUBIT and CUBIT-Pro, provide single-chip ATM/IP switching capability in access equipment. These products have been designed into many system vendors' solutions since late 1995, establishing CellBus as a significant technology in the global broadband network access market. The Company's ATM/IP products also include VLSI semiconductor devices for line interfacing and service adaptation functions.
TranSwitch has sold its VLSI devices to more than 400 customers worldwide. The Company's customers include Alcatel, Cisco, ECI Telecom, Ericsson, GEC Marconi, Lucent, Nortel, Redback Networks, Siemens and Tellabs. The Company sells its products through a direct sales force and a worldwide network of independent distributors and sales representatives located in the United States and 16 other countries.
The Company's competition consists of specialized semiconductor companies from the United States as well as other countries and semiconductor divisions of vertically integrated companies, such as IBM Corporation, Lucent Technologies, Inc., NEC Corporation and Siemens Corporation. The Company's principal competitors in the asynchronous/PDH and SONET/SDH areas are Applied Micro Circuits Corporation, Conexant Systems, Inc., Crystal Semiconductor Corporation, Dallas Semiconductor Corporation, EXAR Corporation, Lucent Technologies, Inc., National Semiconductor Corporation, PMC-Sierra Inc., Texas Instruments Inc., TriQuint Semiconductor, Inc., Vitesse Semiconductor Corporation and VLSI Technology, Inc.
In addition, there are a number of ASIC vendors, including AMI Industries, Inc., LSI Logic Corp. and STM Microelectronics Group, which compete with the Company by supplying customer-specific products to OEMs. In the ATM area, the principal competitors include all the vendors mentioned above and, in addition, Advanced Micro Devices Inc., Integrated Telecom Technology Inc. and MMC Networks Inc.
