Turnstone Systems Introduces Industry's First Remote DSL Spectrum Analyzer CrossScope(TM) Provides Remote Spectral Analysis for Any Copper Local Loop Connected Through a Copper CrossConnect CX100 March 2, 1999 MOUNTAIN VIEW, Calif., March 1 /PRNewswire/Turnstone Systems today announced CrossScope Spectral Analysis Software, a powerful new application that leverages the Copper CrossConnect(TM) CX100 to provide in-depth spectral analysis of any copper loop in the network. CrossScope provides remote Network Operations Center (NOC) personnel with easy-to-read graphical displays of volts versus time, or spectrum plots, for signals on any copper loop in the service providers copper plant, without requiring technicians to visit a Central Office (CO) with specialized test equipment. CrossScope reveals potential spectral compatibility problems, such as interferers, identifies the type of Digital Subscriber Line (DSL) on the line (ADSL, SDSL, etc.) and reveals potential impairments to the DSL signal. "CrossScope is like having a remote, software-based oscilloscope that can tap into any service line in the network," said Eric Andrews, Vice President of Marketing. "It enables the local loop experts to sit at a PC in their office and quickly troubleshoot any issue that gets escalated from the field, without requiring extra service visits with specialized test gear. It's the most cost-effective and convenient way to perform a thorough analysis of what's really happening on the copper local loop." CrossScope is the newest member of Turnstone's Copper CrossConnect product family, a suite of products designed to automate the operational tasks associated with installing and maintaining copper local loop facilities. A network manager can use CrossScope to connect to any copper loop served by a Copper CrossConnect CX100, and capture a real time waveform displayed in volts/time or spectral view. Users can isolate particular frequency ranges they want to examine, such as the Direct Current (DC) voltage, the voice band or the higher frequency DSL range. These signals can also be averaged over time to provide a clear picture of what is happening on the line. These capabilities enable service providers to detect problems such as floating DC voltages, impacts from power lines (power cross), crosstalk from telephone ringing, wideband noise, and DSL crosstalk. Furthermore, benchmark snapshots of standard DSL signals, such as SDSL, IDSL and ADSL, are built into the software, so that users can quickly compare the signal they are seeing with the signal that should appear. CrossScope also enables users to store spectral results, maintaining a useful history for troubleshooting and analysis in the future. CrossScope software runs on a standard PC, and can connect to any one of a number of Copper CrossConnects deployed in the network. CrossScope is currently in Beta with several service providers, and will be generally available in April 1999. Pricing for CrossScope starts at $20,000.
