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. 
PARITY:DATA-BITS:STOP-BITS = N81
