Amati Announces Industry's First Standard ADSL/DMT Core Design Module Set; Design Based on Amati's Overture 8 ADSL/DMT Modem.DALLAS--(BUSINESS WIRE)--June 25, 1996--Amati Communications Corp. (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 : AMTX), today announced an ADSL/DMT Modem Module Set, the industry's first board-level modem design product for ADSL See DSL. ADSL - Asymmetric Digital Subscriber Line services that uses the standard Discrete Multi-Tone Discrete Multi-Tone (DMT) describes a version of multicarrier DSL modulation in which incoming data is collected and then distributed over a large number of small individual carriers, each of which uses a form of QAM modulation. (DMT See DSL. ) technology. The new ADSL/DMT modem module design is a 2-daughter board set -- a central office module (COM (1) (Computer Output Microfilm) Creating microfilm or microfiche from the computer. A COM machine receives print-image output from the computer either online or via tape or disk and creates a film image of each page. ) and remote subscriber module (RSM RSM (in Britain) regimental sergeant major ) -- which provides OEMs with a complete design needed to incorporate high-speed data transmission per the industry standard T1.413 over a copper subscriber line The line from the customer site to the local telephone company. See subscriber network. . Only external power sources, clock and serial data interfaces and line connector need to be added to complete the solution. "Following release of the OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and version of the Overture 8 ADSL/DMT modem used in the Australia Broadcast Video trial, we received numerous requests to make the core technology available as an add-on design for other OEM system designers," said James Steenbergen, president and CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of Amati. "To meet these requests and to ensure interoperability of all ADSL/DMT designs, we are making this core design generally available to manufacturers wanting to include ADSL/DMT technology in their system architecture." DMT, developed by Amati and now incorporated as the industry ADSL standard in ANSI (American National Standards Institute, New York, www.ansi.org) A membership organization founded in 1918 that coordinates the development of U.S. voluntary national standards in both the private and public sectors. It is the U.S. member body to ISO and IEC. T1.413-1995, is a method to produce optimum ADSL transmission rates for video and data over existing subscriber loop installations. ADSL, using DMT, permits existing copper twisted pair A thin-diameter wire (22 to 26 gauge) commonly used for telephone and network cabling. The wires are twisted around each other to minimize interference from other twisted pairs in the cable (Alexander Graham Bell invented this and was awarded a patent for it in 1881). to the subscriber to become high-speed information pipelines. Amati ADSL/DMT Modem Module Set At the core of Amati's high-speed ADSL implementation is a set of application-specific integrated circuits (ASICs) and commercially available digital signal processors (DSPs). This technology enables discrete multi-tone (DMT) design and ADSL data transmission rates up to 8 Mbps. This same technology is the design core for the Overture 8 ADSL/DMT Modem for Internet Access, the highest speed, commercially available modem today. The COM and RSM modules are designed to enable multiple simplex and duplex data ports as described in the ADSL services standard. The interfaces include two simplex ports capable of combined bandwidth to 8 Mbps for lines to 12000 feet. The simplex direction is normally from the central office toward the subscriber location. The modules also include two duplex ports which provide combined data transmission access between the COM and RSM at rates from 32 Kbps up to 384 Kbps. These channels can be used for dual direction communication or as return information channels for data protocols or video system commands. Rate Adaptation Unlike non-DMT-based ADSL modems, the Amati ADSL/DMT modem design provides for standard rate adaptation as described in T1/E1 specification T1.413 for ADSL. The module set automatically modifies the connected data rate to allow for distance extremes or noisy environment, providing the maximum bandwidth for any line conditions. In operation, the Amati design will attempt connection at the maximum rate first (8 Mbps). If the line condition does not permit this bandwidth, the unit will re-establish connection at a lower data transmission rate. The capability to automatically adjust to the characteristics of the line and provide the optimum performance per line is inherent in the DMT standard implementation of ADSL. Interoperability Key to ensuring availability of a truly ubiquitous ADSL service is interoperability of the modems used in the service. The establishment of standards, such as the T1.413 standard, enables vendors to design to a set of parameters and features common to all users. Amati is dedicated to the interoperability of ADSL/DMT modems and designs products to meet the set standards. Amati enables interested vendors to test with Amati products as they become available for evaluation. The availability of the new advanced modules further enables vendors to develop interoperable ADSL interfaces based on the established standard. Pricing and Availability The OEM module design package specification is now available from Amati. The package includes a detailed timing description, board layout, power requirements and interface pin-out. The modules is expected to be available for prototype testing in August 1996. Module pricing is available from Amati Sales. For larger system requirements, Amati can also support a design of the module circuit onto a system specific form factor and interface specification.
