ndoor equipment failure trap.
Can be caused by:
power supply failure, watchdog timeout, or other internal
failure on indoor unit.

r intermittant ODU hardware failure trap.  
Could be loss of reference signal from IDU or hardware error.

t deviation of ODU temperature from specified limits  
May be power amp heating up or environment heat buildup, or
environment ice or frost.

 indicate that ODU is approaching a significant 
deviation of ODU temperature from specified limits. 
May be power amp heating up or environment heat buildup, or
environment ice or frost.

gnal strength at the odu is lower (in dB) than wtnOduRxRSSIThresh.  
This alarm will persist until the RSSI rises above wtnOduRxRSSIThresh - wtnOduRxRssiHysteresisWindow.
          
May be from signal path degradation.  
May be power amp heating up or environment heat buildup.

rts temporary BER > threshold alarm. 
Condition is true when current BER > wtnMdmRxBERThresh.
Condition will persist until current BER < ( wtnMdmRxBERThresh - wtnMdmRxBERHysteresisWindow ).
          
Probable fade burst.  
Could be interference.  
Could be incipient hardware fault

rts temporary post-detection signal to noise ratio 
below preset threshold   wtnMdmRxEbNoThresh.
          
This condition will persist until the radio signal quality
rises above wtnMdmRxEbNoThresh - wtnMdmRxEbnoHysteresisWindow.
          
Probable fade or noise burst.

al indoor equipment failure trap.
Can be caused by:
spurious power supply failure, 
or other temporary internal failure on indoor unit.

ailure of IDU to ODU communications link trap.
can be caused by:
IDU/ODU cable failure, 
bad connection, or 
equipment failure.

nt failure of IDU to ODU communications link trap.
can be caused by:
IDU/ODU cable failure, 
bad connection, 
or spurious equipment failure.

or persistant loss of lock of internal clocks 
in indoor unit.

r intermittant loss of lock of internal 
clocks in indoor unit.

head channel failure trap. May be caused by 
signal path degradation, or equipment failure on local or
far end node.

r intermittant radio overhead channel failure trap.  
May be caused by signal path degradation
or equipment failure on local or
far end node.

DU hardware failure trap.  Possible causes:
Synthesizer has lost desired frequency.
Could be loss of reference signal from IDU or hardware error.  
Synthesizer hardware fault.
Possible component fault.
