Sounding
Sounding is used to test the quality of the channels and propagation paths of all channels in the net.
The sounding signal is normally repeated automatically, at regular intervals. A complete round of sounding messages, or "sounding cycle" can be programmed to 30, 60, 90, or 120 minutes, or can be set to OFF.
Sounding can also be initiated manually whenever necessary, even if automatic sounding is enabled.
