► Note : How to set ALC / Shutdown Target Value.
① When user set downlink path output power is 40dBm :
About ALC, DL output power value is 40dBm. Therefore, set ALC target value
as 40.
② Normal field situation, shutdown target value will be 43, 3dB higher than ALC
target value.
► Note : How to work ALC and ASD
If the ALC gets activated with system output exceeding ALC Target values, you
need to use the USER ATT to adjust the output to meet the range of the upper
settings. If the output exceeds the Attenuation range (30dB), the ALC FAIL alarm
will occur. If the system output exceeds the Shutdown Target value due to lack of
attenuation, then the ASD (Auto Shut Down) will be activated.
If output exceeds the Shutdown target values and makes the repeater shut down,
the repeater goes back to the active status after the ‘Shutdown-on’ time. If the
output of the repeater is higher than the set target value, the repeater will be de-
activated again after the set ‘Shut down-off’ time.
The repeater repeats the process by the Shutdown count. If the output of the
repeater still exceeds the target value after the repetitive work, the repeater will
turn completely off.
