ADIA

• Powerful and complete return path spectrum data analysis and reporting
• Identify trends with measurable node performance and history
• Manage technical operations support with clear problem node identification, reporting and accountability
• Unmatched Flexibility and Ease of Use

ADIA is Trilithic's new ingress analysis application, specifically designed for convenient and efficient historical analysis of upstream performance over periods as long as a year. ADIA collects summarized ingress data from Guardian II installations in hubs and headend, building a data base that can be used for analysis of:

• Persistence and severity of ingress outbreaks over time
• Recurring and long-term intermittent ingress problems on selected nodes
• Suitability of frequencies and bands to carry services

The Trilithic ADIA Integrated Server Package is a pre-configured server, integrating powerful software applications and hardware to provide a tailored, comprehensive solution for managing return path spectrum data. In addition to Microsoft® 2003 Server and SQL Server, the server hardware comes pre-configured with ADIA server software.

The ADIA analysis server provides all of the recommended tools, as specified in the NCTA Standard Practices, for evaluating a return path in terms of performance to limits and for tracking changes in performance over time. Using Trilithic’s ADIA engineers can quickly determine, over specified intervals within selectable frequency ranges and bands:

• The Max/Min/Avg. levels of noise, ingress and traffic levels

  Displays the Max, Min and Avg. levels for all frequencies between 375 kHz and 65 MHz.

• The Average Discrete Interfering Signal Probability

  Calculates the average probability that a node will exceed its thresholds over a user-specified time interval. The ADISP is useful as a “Figure of Merit” test for a node’s overall performance.

• Ingress Threshold Probability

  Plots % unavailability vs. frequency and threshold for each frequency over a user specified time period.

• Specific Frequency Discrete Ingress Probability

  Calculates the DISP as the percent of threshold violations for each of the four user thresholds for each time increment.

• Specific Channel Discrete Ingress Probability

  Similar to Specific Frequency Discrete Ingress Probability, this function allows analysis to be performed in user-selectable bandwidths

ADIA assists in the analysis with graphs, "waterfall" diagrams and tabular results to facilitate recognition of threats and trends. Data for several nodes may be displayed simultaneously, with data for any selected node highlighted. All graphs and reports may be stored and later recalled quickly without requiring the original compressed data to be reloaded.
