This description applies to the AMPS-TACS mode.

The 7 hexadecimal characters of the FVC Message field represent the 2 type bits and 26 information bits in the FVC message word.

The generation of dotting, word sync, parity, and the 11 repetitions of these parameters in the FVC message stream is done automatically.

Operating Considerations

The entire field must contain data, no blank spaces are allowed. SAT is turned off while the FVC message stream is being sent.
