 SKOKIE, Ill., Aug. 23 /PRNewswire/ -- U.S. Robotics, Inc. (NASDAQ: USRX), today announced a major evolution to its Courier modem line; the company will ship new Courier models beginning September 1 that include a battery of new features, most notably the 19.2 Kbps V.32 terbo protocol and U.S. Robotics' proprietary Adaptive Speed Leveling (ASL/TM/) technology, which further boosts speed to 21.6 Kbps. The new features fall into three broad categories: increased data rates, fax enhancements and high-end features. The company is offering an upgrade program for current Courier high-speed modem users, also beginning September 1.
 U.S. Robotics Among First To Ship V.32 Terbo
 Among the features included in the new modems is V.32 terbo, a new protocol for 19.2 Kbps data transmission developed by AT&T; Courier modems will be among the first shipping products to include V.32 terbo, which delivers a 33 percent increase in speed over the 14.4 Kbps V.32 bis standard. The move to V.32 terbo is in keeping with U.S. Robotics' philosophy of developing modems that support a variety of protocols and provide compatibility with a wide range of modems from other vendors.
 These products allow Courier customers to take advantage of increased data rates, while still assuring them of a clear upgrade path to the forthcoming standard. Additionally, the new modems provide Courier customers the added benefit of proprietary technology that boosts connect speed to 21.6 Kbps.
 Proprietary ASL Increases Speed To 21.6 Kbps;
 DTE Interface Rate Jumps To 115.2 Kbps
 The Courier V.32 terbo modems include the company's proprietary Adaptive Speed Leveling (ASL) protocol, boosting throughput to 21.6 Kbps, a 50 percent increase in speed over the current 14,400 bps V.32 bis standard. This protocol allows users who are connecting two Courier modems to take advantage of the 21.6 Kbps rate; V.42 bis data compression provides an additional increase in throughput. An increased DCE to DTE (modem-to-computer) interface rate of 115,200 bps and faster processors accommodate these higher speeds.
 Courier Modems Still Upgradable To V.Fast (ITU-T V.34)
 The new Courier modems, like the current Courier high-speed models, will be field upgradable to the forthcoming standard, which will likely be named V.34. Availability will depend on ITU-T progress in finalizing the standard; however, study group approval of V.34 is expected in June, 1994. The standard will provide data rates of up to 28,800 bps.
 Dale Walsh, U.S. Robotics vice president, advanced development, and a member of the ITU-T committee developing the V.34 standard, points out that V.32 terbo should not be confused with the standard. "The V.32 terbo protocol is really an extension of V.32 bis," said Walsh. "In fact, when you compare the processing power necessary to run V.32 terbo and V.34, the processors in V.32 terbo modems are more like the processors used for V.32 bis -- they are certainly not capable of achieving the 28.8 Kbps throughput that will be available with V.34."
 U.S. Robotics' upgrade to V.34 is performed via a daughterboard swap, which takes a typical user about five minutes. Because the pending V.34 standard requires two to three times the processing power of V.32 bis, both the hardware and software must be upgraded to provide enough power and ensure that there are no hardware bottlenecks that might impede the speed of V.34.
 Upgrades To New Product Available For Current Courier Users
 Current Courier users may upgrade to the new models. Pricing will vary depending on the modem model being upgraded. The upgrade program will include both current-model Courier modems, which may be upgraded via a daughterboard swap, as well as older-model Courier modems, which may be exchanged for the new models. Courier 2400 bps modems are not included in the upgrade program.
