IDU_EQUIP_FAIL - can be caused by:
power supply failure, watchdog timeout, or other internal
failure on indoor unit.

IDU_ODU_LINK_FAIL - can be caused by:
IDU/ODU cable failure, bad connection, or equipment failure

IDU_OOL - can be caused by:
intermittent loss of lock of internal clocks

MC_CHANNEL_FAIL - can be caused by:
Signal path (air) degradation, or internal equipment failure 
on near end or far end node.

ODU_EQUIP_FAIL - can be caused by:
Loss of frequency lock, loss of clock reference, power fault, 
excessive transmitter power, signal path degradation, 
frequency drift, or internal failure of equipment in outdoor
unit.

ODU_TEMP_ALERT - can be caused by:
Operating temperature too high or too low.   Allowable range
of operating temperatures ( in ODU ) are -40C to +65C.

RSSI_DEVIATION - can be caused by:
signal path (air) degradation, excessive heat buildup at ODU,
or frequency drift.

RX_BER_ALARM - can be caused by:
RF noise burst, fade burst, interference, or internal equipment 
failure.

RX_EBNO_ALARM - can be caused by:
Fade, noise burst, or internal equipment stress.

SERVICE_AFFECTED - indicates a predicted loss of data 
or quality of service in transport due to any of the 
above conditions.

What is wtnCriticalAlarmStatus?

Bitmap of critical radio alarm conditions currently active, such as RSSI deviation, ODU/IDU equipment failure, IDU-ODU link failure, BER or Eb/No alarms, or an overall service-affected flag; an admin reads this to see at a glance which of the defined critical fault conditions are outstanding on the radio link.
