Trilithic 9581 SST Return Path Analyzer

The 9581 SST


Your 9581 SST Return Path Maintenance System is a single test system that enables you to deal with all aspects of return path upkeep; including both ingress control and system balancing. At the core of the system is the SST Unit, a 0.3 to 65 MHz digitizing spectrum analyzer, which is installed at the headend of your cable system.The 9581 SST? is the hub of the Guardian System II? for return path maintenance, providing installation, reverse sweep and ingress spectrum information to field technicians using Trilithic?s field units. When used in a Guardian System II, the 9581 SST shares spectrum information with the monitoring facility and the field units, speeding up problem identification and shortening repair times. The 9581 SST monitors the return band, generates SNMP traps, and relays monitored data to NOCs and designated network engineers. Extremely flexible, each SST supports up to twelve distribution technicians and a virtually unlimited number of installers. It can provide live spectrum information and recent historical data to as many as eight independent monitoring sites, each using its own SNMP trap criteria. Traps sent to each of these sites can be configured for different ingress severity alarm limits and persistence.


Ability to Capture All Types of Ingress

Cutting-edge DSP technology gives the 9581 SST unmatched power for capturing all types of ingress, including the short bursts that degrade VoIP services. Up to 100 times faster than analog-based analyzers, the 9581 SST captures and analyzes the entire spectrum of all connected nodes in microseconds and rescans them up to 120 times per second. Thanks to the 9581 SST?s unmatched scanning speed and high rescan rate, the NOC operator or field technician never misses an ingress outbreak capable of disrupting return services.


Features a Wide Selection of Operating Modes

A wide selection of operating modes makes the 9581 SST a highly versatile return path troubleshooting aid.


The 9581 SST simultaneously supports:

• Installation tests
• Distribution sweep and maintenance
• Return path performance monitoring

Each 9581 SST can:

• Support up to 16 individual nodes
• Support up to 12 distribution techs
• Support dozens of installers
• Send traps and live spectrum data to as many as eight server sites
