New satellite-based ATM services announced by COMSAT World Systems -- Commercial ATM services via satellite debut in Fall of '96 with promotional rates --.LAS VEGAS Las Vegas (läs vā`gəs), city (1990 pop. 258,295), seat of Clark co., S Nev.; inc. 1911. It is the largest city in Nevada and the center of one of the fastest-growing urban areas in the United States. , Networld+Interop--(BUSINESS WIRE)--April 2, 1996--Two new, satellite-based Asynchronous Transfer Mode See ATM. (communications) Asynchronous Transfer Mode - (ATM, or "fast packet") A method for the dynamic allocation of bandwidth using a fixed-size packet (called a cell). See also ATM Forum, Wideband ATM. ATM acronyms. Indiana acronyms. (ATM) transmission services will be available in the fall of 1996, COMSAT Comsat: see Communications Satellite Corporation; communications satellite. (COMSAT General Corporation, Bethesda, MD) Formerly Communications Satellite Corporation, COMSAT was a private company that was created by the U.S. World Systems announced today. The new ATM services will allow companies to transmit voice, data, video and images at speeds up to 45 Mbps. According to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. COMSAT officials, who made the announcement at the Networld+Interop '96 show, these two commercial services are the first to solve the demanding ATM performance requirements over satellite. Promotional Program COMSAT also announced that, for a limited time, it will provide its new ATM Enhancement Services, free-of-charge, to customers that enter into new space segment leases. The new ATM services will use two COMSAT-designed satellite interfaces, the ATM Link Accelerator and the ATM Link Enhancer, that condition the INTELSAT space segment for fiber-like transmission quality. Under COMSAT's promotion, the new ATM services will be provided free-of-charge when space segment service is ordered before May 31, 1997, or until all promotional interfaces are shipped, whichever occurs first. COMSAT Laboratories, working in conjunction with COMSAT World Systems, designed the ATM Link Accelerator and ATM Link Enhancer to be used at the earth station or at the customer's premises to enhance the performance of ATM via satellite to the quality level of fiber. When ATM Enhancement Services is used in conjunction with COMSAT space segment, COMSAT will guarantee ATM quality of performance levels and provide a "lifetime" warranty for the interface. Intermediate Rate and High-Speed Services See broadband. COMSAT's Intermediate Rate ATM Enhancement Service supports ATM links at fractional T-1 through 8 Mbps data rates and uses the ATM Link Accelerator, which increases link throughput using lossless data compression Lossless data compression is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data. This can be contrasted to lossy data compression, which does not allow the exact original data to be reconstructed from the and Reed Solomon coding for fiber-like quality. COMSAT's High-Speed ATM Enhancement Service supports ATM links at DS-3 or E-3 rates and uses the ATM Link Enhancer, which employs zero-overhead Reed Solomon coding to increase bandwidth efficiency The introduction to this article provides insufficient context for those unfamiliar with the subject matter.

Both services are full duplex (Computers) arranged so that the information may be transmitted in both directions simultaneously; - of communications channels between computers; contrasted with "COMSAT, through its Laboratories and World Systems business units, is dedicated to ensuring that satellites are a viable option for businesses implementing ATM strategies on a wide-scale basis," said John Mattingly, vice president and general manager for COMSAT World Systems. "Satellites have the highest reliability and quality ratings for voice, data and video delivery and through the use of the specialized satellite interfaces, that's true for delivery of ATM, too." Benefits of Satellite Satellite links can reach locations around the globe, particularly in places where fiber is not in place. Additionally, satellite transmission is relatively inexpensive compared to the cost of developing a fiber network. The flexible bandwidth of satellites and their ability to provide point-to-multipoint connections fit well with ATM's technology. "The availability of ATM via satellite will be exciting for many multinational corporations
COMSAT World Systems is the business unit of COMSAT Corp. (NYSE NYSE See: New York Stock Exchange :CQ) that provides international telecommunications and broadcast services using the INTELSAT network of satellites. COMSAT was the first to demonstrate that commercial satellites can successfully carry ATM traffic in 1993, and in 1994 and 1995, conducted two separate satellite-transmitted ATM demonstrations in the Atlantic and Pacific Ocean Regions.
