AGC (Automatic Gain Control)
AGC prevents the repeater from exceeding its maximum output power by reducing the gain
automatically. AGC is used to adjust the gain to an appropriate level for a range of input signal
levels
.
ASD (Automatic Shutdown)
ASD helps protect the amplifier from over load. ASD helps protect the network by preventing
excessive signal output power.
There are three parameters: ASD Level, ASD Time, and ASD Iteration.
If the output power exceeds higher than the “ASD LEVEL”, the repeater will shut down for “ASD
TIME” seconds. If shutdown repeats “Iteration” times, the repeater will require manual re-start.
