U.S. ROBOTICS ANNOUNCES 33.6 KBPS V.34 SOFTWARE FOR SPORTSTER Costs only 25$ around 170 SKR New Software Boosts Throughput at Lower Speeds and Increases V.34's Top Speed SKOKIE, Illinois, -- November 3, 1995 -- The Personal Communications Division of U.S. Robotics (NASDAQ: USRX) today announced new software for the Sportster line of V.34 desktop modems that provides a top speed of 33.6 Kbps. The result is enhanced performance connection between any two modems running the new V.34 software. The software provides two new speeds, 33.6 Kbps and 31.2 Kbps, for the V.34 standard. U.S. Robotics' 33.6 software implements the new higher speed options inherent in the ITU V.34 recommendations awaiting formal approval. ITU Study Group 14 has arrived at a technical consensus on V.34 code enhancements that boosts the top speed of the standard to 33.6 Kbps. "The ITU has completed its technical and drafting work and will soon formalize the 31.2 Kbps and 33.6 Kbps enhancements to V.34," said Dale Walsh, U.S. Robotics vice president of advanced development and a member of the ITU committee responsible for developing V.34 and subsequent additions to the standard. "Our new software conforms to the enhanced standard. Formal approval of the enhanced standard will occur at the next Study Group 14 meeting in Geneva." "Our 33.6 software offers two major advantages," noted Michael Seedman, vice president and general manager of the Personal Communications Division. "Not only is the top possible speed boosted to 33.6, but the overall throughput is significantly increased. Not all phone lines will support 33.6 Kbps, of course; but our lab tests indicate the average connection between two U.S. Robotics products running the new software will consistently be 2,400 to 4,800 bits per second faster than older versions of the V.34 code," Seedman noted. "For example, on a connection where a customer might typically experience 26,400 bps, it's likely the new software will allow a connection at 28,800 bps on a regular basis," Seedman added. "We achieved this increase by tuning our algorithms to support the higher speeds offered by the enhanced V.34 standard. By pushing the barrier of higher speeds, we're able to provide a dividend of faster connections across the entire spectrum of speeds available with V.34." The 33.6 software is included in all newly shipping Sportster desktop products. An EPROM chip replacement containing the new 33.6 software will also be available for owners of current V.34 Sportsters to upgrade their modems. Customers can order the V.34 upgrade chip for $24.95 plus shipping by contacting U.S. Robotics customer support.
