The only controls available to the master are the Interference Threshold attribute. This
has no effect on the operation of the wireless link and will only affect the generation of the
channel spectrum graphics. See
1140HFigure 82.
Extra color coding of the interference histogram is provided. See
1141HTable 17.
When operating with RTTT Avoidance enabled or other regulatory restrictions on channel
usage the following variances apply:
All channels marked with a ‘no entry’ symbol with their associated statistics colored black
are the prohibited channels. See
1142HFigure 82 and 1143HFigure 83. These channels are never
used to host the wireless link, but CAC measurements are still taken so that adjacent
channel biases can be calculated correctly and so the user can see if other equipment is
in use.
