The ‘I’ Bar is used to display the mean of means and peak of means metrics. The lower 

horizontal bar represents the mean of means and the upper horizontal bar represents the 

peak of means. The vertical bar is used as a visual cue to highlight the statistical spread 

between the peak and the mean of the statistical distribution. 

The peak symbol (the upper small triangle above each channel ‘I’ bar) is used to indicate the 

peak of peaks interference measurement. 

8.3.8.8  Active Channel History

 

The active channel history is a time series display of the channels used by the PTP 400 

Series Bridge over the last 25 hours. The active channel history is activated from the main 

Spectrum Management page using the ‘Active Channel History’ hyperlink. An example of the 

active channel history display is shown in Figure 59. Where there are parallel entries on the 

display this signifies that the wireless link occupied this channel during the measurement 

period. The measurement periods are one minute from zero to sixty minutes and twenty 

minutes from 60 minutes to twenty five hours.
