The active channel history is a time series display of the channels used by the Canopy
150/300 Mb BH 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 56. 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.
