A VoIP Imperative

Guardian System II is an integrated system of hardware and software that supports all return path maintenance activities from installation testing, to distribution system alignment and ingress control, to ingress monitoring and real-time, NOC-level troubleshooting. All elements of Guardian II are closely linked for maximum efficiency, flexibility and optimum cost-effectiveness. Monitoring the return band with DSP technology enables capture of fast transient impulse noise and ingress, as well as visibility of interfering signals beneath service carriers using unique TraffiControl feature.

Installation

The Guardian RSVP² Installer's Return Tester has become the industry standard or preventing return path installation problems, with many thousands in daily use. Communicating with a 9581 SST in the headend, the RSVP² verifies both the transmission level from the house and the Carrier/(Ingress+Noise) ratio of the entire path from home to hub. Fast and very simple to use, RSVP² remains the only installation tester with sufficient measurement range to insure trouble free return services. An expanded version of the RSVP², Option VP-1, is also available in the 860 DSP Signal Analyzer. The VP-1 simultaneously tests the performance of up to 8 frequencies and assigns to each its individual pass or fail rating.

Distribution Alignment and Ingress Control

Working with an 9581 SST in the hub, the 9580 SSR displays errors in amplifier gain and tilt both as a graph and as calculated values. The SSR also displays the return ingress spectrum, as scanned by the SST, as an aid for troubleshooting ingress. SSR functions are also available in the 860 DSP Signal Analyzer, Option SR-1, with additional capabilities including a screen that compares the ingress seen by the SST with the ingress at the field connection point Real-time.

Diagnostic Operations

Viewer II software gives the operator considerable flexibility in servicing SNMP traps from 9581 SSTs displaying spectra for viewing and analysis and managing the heavy flow of alarm traffic typical of a busy NOC. Node topology can be organized by geography, facilities and services, and even by maintenance organization. Viewer II enables the operator to select from a wide range of resolution bandwidths, frequency spans, detector types and other functions needed for efficient trouble shooting.

Bringing It All Together

Guardian System II is a powerful, flexible system of field and central office products supporting all aspects of return path management including installation, distribution system alignment and ingress control, ingress monitoring and real-time troubleshooting. The 9581 SST, the hub of the Guardian II System, supports field technicians using Trilithic RSVP², 9580 SSR and 860 DSP field units and network-connected engineers using Trilithic Viewer II, IngressManagR and DIA software. All elements of the return maintenance process are closely linked for maximum efficiency, flexibility and optimum cost-effectiveness.
