Basically, each service band’s UL Gain value is controlled by AGC. The ALC maintains UL output level is under
[Rated power
±
2dB]. The attenuator used for ALC function for UL over-output is same hardware as the one used
for the ALC function for UL over-input. The attenuator for the AGC uses a different hardware from the ALC one.
Shutdown for UL/DL over-output
This function is that automatically shutting down the service band when the DL/UL output of each service band is
over the rated. During DL Shutdown, UL Shutdown is also proceed at the same time and this is vice versa. The
operating level is [(Rated output level +2dB)
±
2dB] and working algorithm is described as follows.
In ‘Check’ state, if the power level is back to normal from over-output level, the algorithm is reset. If ‘Complete
Shutdown’ occurs, a repeater is kept shut-down state, until performing Power on / Reset / Isolation Re-check.
Dying Gasp
This function is to report the alarm "Failure of the DC power supply" to the NMS using the standby power from a
connected capacitor if the DC power supply of the repeater is interrupted.
