Press Release Trilithic’s Media Contact: Karalee Slayton Director Marketing & Communications 317 423-6604 kslayton@trilithic.com Product Release: Guardian II Integrated Server Package Indianapolis, Indiana (Tuesday, April 11, 2006) Trilithic is pleased to introduce the Guardian II Integrated Server Package, which includes an extensive viewing and management server application for return band monitoring, designed to make optimum use of the broad feature sets of Trilithic monitoring equipment (9581 SST-Release 4 Return Path Analyzer), used for spectrum management and troubleshooting. The integrated package includes high-performance server hardware, Microsoft Windows and SQL Server software, and Viewer II, V2.0 for application specific monitoring and management. The Viewer II v2.0 application displays and manages SNMP traps gathered from strategically deployed 9581 SST’s, provides extensive reporting and analysis, and serves as a live-view spectrum display for operator selected nodes. The operator can control 9581 SST-R4 units in hubs or headends, permitting selection of resolution bandwidths, displayed frequency span, detector modes and other characteristics. The 9581 SST has the fastest reverse path spectrum acquisition speed on the market, catching transient impulse noise that others miss. The only reverse path monitoring system that comes pre-installed on a high performance server, the Guardian II Integrated Server Package ensures reliability and minimizes system activation time with dedicated hardware designed for the application, resulting in a more cost effective result. The enhanced reporting capability of the Viewer II, v2.0 application provides a summary system health overview, with the ability to drill down for more specific information. Reports include a node alarm summary, worst offenders report and node alarm history. The application also includes versatile tools for real-time diagnosis and problem resolution.
