SAT-ALM
TX-TERR-AIS= MASKED
RX-SAT-AIS = ACTIVE
If Tx-TERR-AIS is set to ACTIVE, a fault will be generated whenever the
modulator senses that the 'all ones' condition is present in the terrestrial data.
If Rx-SAT-AIS is set to ACTIVE, a fault will be generated whenever the
demodulator senses that the 'all ones' condition is present in the receive data.
If an alarm is MASKED, no alarm will be generated.
If the user selects ACTIVE, then a Buffer Slip fault will be generated whenever
the receive circuitry senses that the buffer has either underflowed, or overflowed.
If the user selects MASKED, no alarm will be generated.
