Watch this video highlighting new features in PreEqualization Analyzer 2.0.
Following is a summary of the changes in version 2 of PreEqualization Analyzer. You can also click the image to the right to watch a video.
NEW MAIN DASHBOARD SUMMARY
A new Main Dashboard summary shows high level CMTS statistics, including the number of CMTSs being monitored and the total change in red modems over the last 24 hrs for all CMTSs on the system. There is also an overall Health score for all CMTSs on the system, which is derived by looking at the number of red and yellow modems in relation to the total number of modems. There are also summary stats showing the breakdown of Red, Yellow and Green modems and the percentage change for each over the last week. The map and charts are now accessed by clicking “Detail View” under the Dashboard menu.
Map Zoom Button
You can now expand the size of the map by clicking an Expand button located on the map.
A “Show/Hide RF Values button over the table displays data on the RF levels for that device over time.
A “Re-Correlate” button allows you to change the sensitivity of the correlation algorithm. The values in the selection box correspond to the level of micro-reflections in dBc. The recommended setting for correlation is -18 dBc. You can lower the threshold for correlation groups by selecting a lower micro-reflection level like -19, -20, etc. Selecting a lower micro-reflection level will make it more likely that you will see correlation groups. However, it will also make it more likely that you will see weak correlation groups, which may not be representative of a common impairment, or if they are, may be difficult to see because the cause of the impairment is not that bad yet.
Correlation Groupings by Frequency
When you select a correlation group you will see additional correlation groups if there are modems nearby on a different frequency that appear to be correlated due to the same impairment. Each individual group of correlated modems on a specific frequency are color-coded differently in the map and in the table.
Map Indicator for Modems at the Same Address
If there is more than one modem geocoded at the same address or very close by, a blue map pin appears with a number that indicates the number of modems at that same location. For example, if there are three modems in a unit with the same physical address, there will be a blue map pin with a “3”. When you double click the blue pin you see the details for one of the modems. There is an arrow in the details box that will page through the details for the other modems at that same address.
