ALC (Auto Level Control)
ALC maintains limit of the output power in order to protect bad influence to the Base Station.
AGC (Auto Gain Control)
The Signal Booster checks isolation between inside and outside antennas once a day.
AGC sets up downlink and uplink gain value automatically depending on the input power level.
ASD (Auto Shutdown)
There are two cases when ASD works.
1) Outside antenna and Inside antenna are not isolated enough from each other.
So in order to protect the Signal Booster from damage, it will automatically shutdown at this
frequency.
2) Uplink Signal coming from the outside antenna to Base Station is too strong and may cause
troubles to carriers network, so the Signal Booster will shutdown at this frequency.
