alarm currently active for each of the alarm types is as follows:
a = Unit status:
0 = No faults
1 = Power supply fault, +5 volts
2 = Power supply fault , +12 volts
3 = Power supply fault, +3.3 volts
4 = Tx synthesizer unlocked
5 = Tx FPGA PLL unlocked
6 = Modulator FPGA load fail
7 = TPC/LDPC FPGA load fail
8 = Reference unlocked (Note: Tx off)
9 = Unit Temperature Exceeded
b = Tx Traffic status:
0 = Tx traffic OK
1 = Tx FIFO slip
2 = Tx 130 MHz PLL unlocked
3 = (Hi-Stab) No External Ref found (no activity)
c = Rx 1 Traffic status:
0 = Rx Traffic OK
