The active channel (channel 5 in
1133HFigure 77) is always marked using hatched green and white
lines. The width of the hatching is directly proportional the 30 MHz spectral occupancy of the
channel.
The individual channel metrics are displayed using a colored bar and an ‘I’ bar.
The colored bar represents the following channel state:
Green Active
The channel is currently in use, hosting the Point-to-Point
wireless link
Orange Interference The channel has interference above the interference threshold
Blue Available
The channel has an interference level below the interference
threshold and is considered by the Spectrum Management
algorithm suitable for hosting the Point-to-Point link
Grey Barred
The system administrator has barred this channel from use.
For improved visibility, an additional red ‘lock’ symbol is used
to indicate that a channel is barred.

The top of the colored bar represents the 99.9% percentile metric for specific channel.
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.
