Skokie, IL--March 27, 1997--U.S. Robotics (Skokie, IL) announced the test results of an ISDN terminal adapter (TA) test conducted by XXCAL Testing Laboratories. XXCAL tested the performance of six TA's, including U.S. Robotics' DataBurst ISDN 128K, measuring the average throughput for file transfers using Point-to-Point Protocol (PPP) and Multilink Point-to-Point Protocol (Multilink PPP) connections. The DataBurst with TurboPPP beat its closest competitor by over 240 percent.
The DataBurst is a new desktop parallel port TA that provides a high-speed ISDN solution for telecommuting, remote access, or Internet access. Its advanced parallel port and TurboPPP performance enables users to reach the full potential of ISDN up to 512 kbps without serial port limitations. TurboPPP, a feature set designed by U.S. Robotics, includes Multilink PPP, multiple forms of software-based compression, and Windows 95 enhancements.
The DataBurst was tested in comparison with the 3COM Impact IQ, Adtran Express XRT, Boca Research WebGlider, Motorola BitSURFR Pro, and the Zyxel Elite 2864I. XXCAL's test results showed the speed achieved by Turbo PPP far surpassed all of the competition when performing FTP file transfers.
XXCAL engineers put together a suite of file transfers that was used with each TA. The test environment consisted of a Windows 95 workstation and Microsoft Windows NT 4.0 RAS server.
Each ISDN TA was installed per the manufacturer's documentation. Once a stable connection was made between the ISDN TA from the workstation to the server, XXCAL executed the performance test three times for each TA. The performance testing measured the average throughput time transfer speed of ANSI TR30 test file transfers when being transferred from the Windows 95 workstation to the Windows NT RAS server.
The DataBurst is available in two versions. The U version with an integrated NT-1 is list priced at $279. The S/T version for use with a standalone NT-1 is list priced at $239.
