RSL Thresholds
Two RSL Thresholds can be defined. They are used as an indicator of problems in the radio
channel. You can check the RSS from the Link Budget Calculator results during installation.
Values of -5dB and -8dB from the current RSS are typical.

TSL Threshold

A counter is maintained, of the number of second intervals during which Tx power exceeds
this threshold.
