MINI-LINK E and E Micro
Table 12 Receiver alarms
Alarm Description
TX LOS Receiving direction, low input power to the MINI-LINK E Micro.
RF Input Level The received RF input signal level has dropped below the threshold for
the receiver.
AGC Threshold The RF input level has dropped below the AGC threshold value. The
AGC threshold is set in Main setup.
RX FAIL Transmitting direction, internal failure in the MINI-LINK E Micro.
Rx AFC The frequency of the received signal is outside the range of the Automatic
Frequency control in the receiver.
Rx Frequency The receiver frequency loop is unlocked.
Radio Frame The receiver failed to recognize the frame of the received composite bit
stream de to signal faulty.
Radio ID The received traffic comes from a radio with an ID not matching the
far-end ID as set in the Main setup. This alarm can only be active if the
ID Check is activated in Main setup.
BER The Bit Error Rate (BER) for the received signal has exceeded the BER
alarm threshold. The BER alarm threshold is set in the Main setup (BER
10
–3
,10
–4
, 10
–5
or 10
–6
).
Dmod Clock E1:X The internal data rate does not correspond with the received data rate.
This will cause bit slip in the traffic bit stream.
AIS Received
E1:X
AIS is detected on the received traffic signal for channel E1:X. (This
alarm does not affect the severity of the terminal.)
