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 preconfigured with ADIA server software.
The ADIA analysis server provides all of the recommended tools, as specified in the NCTA Standard Practices1, 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 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.
