(*) The meaning of the digital outputs depends on the firmware release of the RBS.
In the shown example the meaning is as follows:
 Output 1: power supply alarm. When the RBS is supplied from battery the output is closed.
 Output 2: RBS temperature alarm. When the temperature is over a defined maximum value the
output is closed.
 Output 3: RBS synchronization alarm. When the RBS loses synchronisation the output is closed.
 Output 4: RF power alarm. When the PA transmitting power is 3 dB below the right power level the
output is closed.
