o Main downlink control: parameters regarding to downlink band. They are almost
equal to uplink band.
Parameter
Range
Description
Gain control
60dB to 85dB
Set maximum gain of Signal Booster at DL band
Power limit control
+20dBm to +30dBm
Set maximum output power of Signal Booster at
DL band. System automatically will apply a
correction to share this limit between the active
channels. For instance, +36dBm band limit
means +30dBm maximum output power per
channels for 4 active channels
Squelch enable
control
Enabled / disabled
Enabling this control, Signal Booster does not
transmit in each channel if RF input power do
not exceed the threshold level configured
according to next row.
Squelch threshold
control
-80dBm to -40dBm
If squelch is enabled, input levels below this
threshold are not transmitted.
PA enable control
On / off
This control enables / disables PA DL:
Green button and label “ON” means that PA is
enabled, red button and label “OFF” means that
PA is disabled
Rf output power
indicator
---
Shows instantaneous RF output power at DL
band
Input overflow
alarm
Grey: normal state /
Red: alarm state
This alarm indicates that Signal Booster is being
overloaded at DL band, due to very high RF
input level
PA status alarm
Grey: normal state /
Red: alarm state
PA status alarm indication based on
temperature
PA overflow
Grey: normal state /
Red: alarm state
Alarm active if output level exceeds +40dBm
o General control
Parameter
Range
Description
Squelch mode
control
Linked / not Linked
If this control is set to “Linked”, DL channels
without input signal (according to DL Squelch
threshold) automatically squelch related UL
channels
RESET
---
Reboots digital signal processor
Temperature
---
Shows internal Signal Booster temperature
Base station
alarm
Grey: normal state /
Red: alarm state
Alarm is active, if signal is not detected in any
DL channel
Hardware fail
alarm
Grey: normal state /
Red: alarm state
Indicates critical malfunctioning in digital signal
