5=Power supply fault, –12 volts
6=Spare
7=Tx synthesizer lock
8=Rx synthesizer
9=Power cal Checksum error
A=FPGA main chain load fail
B=Turbo FPGA load fail
C=Modem card FPGA load
D=MUX FPGA load
E=Demux FPGA load
F=(Hi-Stab module) No PLL Lock (Note: suppresses TX)
b = Tx Traffic status:
0=Tx traffic OK
1=No clock from terrestrial interface
2=Tx FIFO slip
3=AIS detected on incoming data
4=AUPC upper limit reached
5= (Hi-Stab module) Ref Activity fault
c = Rx Traffic status:
0=Rx Traffic OK
1=Demodulator unlocked
2=AGC Alarm - signal out of range
3=Demux Lock (Frame SYNC)
4=Spare
5=Buffer Slip
6=AIS detected on incoming data
7=Eb/No alarm
8=Buffer Clock activity
d = Open Network:
