WebSprint's "RADSL" Lowers Cost of High Speed Connectivity
Web Sprinter Dashes Across Ordinary Phone Lines and the Internet
SANTA CLARA, Calif.--(BUSINESS WIRE)--Aug. 18, 1997--An easy-to-install and low-cost high speed networking solution for fast Internet connections, video on demand, and distance learning using ADSL (Asymmetric Digital Subscriber Line) for transport over copper wire pairs was announced today by WebSprint Communications, Inc.
The modem-like device -- called Web Sprinter -- can send and receive data at 7 Megabits per second at distances up to 18,000 feet, using WebSprint's RADSL, (Rate Adaptive Digital Subscriber Line), which allows just about any organization to provide xDSL without a major commitment to a multi-line rackmount system.
At the time of installation the RADSL units test the line to determine the highest data rate that can be supported on that particular circuit. Longer cable lengths can be used with RADSL over non-rate adaptive line encoding. Data rates can be set on the units at fractional rates. Doing so allows Internet service providers to bill customers based upon the bandwidth or service level that customers require and are willing to pay.
WebSprint provides an end-to-end solution which consists of Web Sprinter (upstream) and a similar central CO Sprinter device (downstream). This means users can be up and running in a short time at a low cost -- $1,099 per unit.
Web Sprinter's digital line signal is transmitted over the copper wire pair, converted to 10 BaseT Ethernet signal and connected through an Ethernet Hub or Router to your LAN or directly to your PC through an Ethernet NIC. For video or other serial data
applications an RS422/V.35 interface is provided. Telnet support permits remote configuration and diagnostics.
Websprint applications include local video transmissions for corporate communication or training (TeleLearning); broadcast quality video conferencing; high speed and low cost computer-to-computer connections, and LAN-to-LAN connectivity.
Four LED displays on the Web Sprinter display current link and error status. An RS-232 serial interface provides control and diagnostic communication. Integrated with the transceivers are two dimensional, 8-state Trellis coding with Viberbi decoding and Reed-Solomon forward error correction for reliable transmission in the presence of crosstalk, impulse noise and background noise.
Web Sprinter is part of WebSprint's of DSL product family. xDSL technology has a distinct price/performance advantage because it uses ordinary telephone wires for higher bandwidth (they were traditionally considered unusable for broadband communications). Users can transmit high bandwidth items like television signals, movies, graphics and very high speed data without recabling.
WebSprint, founded in 1996, is developing both the WAN-LAN family of interconnectivity products and xDSL products for the Internet and video conferencing markets. The company can be reached at 408/588-0880 or www.websprint.com . |
