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.


The SERVICE_AFFECTING bit should always = 0 on this variable
because, by definition, minor alarms may not affect service.
