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 reaches higher than the “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 permanently.
1. Introduction
QUAD BAND OTA is used to fill out areas in QUAD BAND systems, such as base station
fringe areas, business and industrial building, etc.
QUAD BAND OTA receives signals from a base station, amplifies and retransmits the signals
