Too Low
Description:
Signal from the Donor antenna (DL) is too low -
relatively to the desired output signal configured by the user.
Recommended action
:
•
Check the Donor/Base connections and antenna position.
•
Check the signal level of the Donor/Base antenna.

Current
Description:
Power Amplifier current is not within limits (too
high or too low). If the Mute option is enabled, then this is not a
fault since it indicates low Power Amplifier current caused by the
mute.
Recommended action:
Check the LEDs status in the Repeater
and Contact Axell service support.
RSSI
Description:
Generates an alarm when a high
donor
input signal
causes system gain reduction
VSWR
Description:
This alarm is triggered when the return loss of the
Downlink or Uplink antenna or cable connection exceed the
allowed limit.
This alarm provides an indication of the status of the
cable/antenna connected to the antenna. If a cable/antenna is
defective, the VSWR is decreased and the alarm is triggered.
Recommended action:
Check the cable.
