ALC (Automatic Level Control)
ALC feature prevents the repeater from exceeding its maximum output power by reducing the gain
automatically. ALC is used to adjust the gain to an appropriate level for a range of input signal levels.
ASD (Automatic Shutdown)
Automatic shut down protects the repeater from the oscillation or excessive input signal and
eliminates any degradation to the network.
There are three parameters:
ASD Level
,
ASD Time
, and
ASD Iteration
.
If the output power gets higher than “
ASD LEVEL
”, the repeater will shut down for “
ASD TIME
”
seconds and then it will turn the amp back on to measure the output power again. If this repeats at
“Iteration” times, the repeater will shut down completely.
