Command Decoder
Timers
Chapter Three: Command Code Structure
Two timers relating to command entry eliminate the effects of
rare but unavoidable Touch-Tone decoder falsing on voice. A
four second interdigit timer cancels. a sequence where any digit
occurs more than four seconds after the last digit. An eight
second "to end of transmission timer" cancels any sequence
where the last digit was received greater than eight seconds
before the end of the transmission.
These timers help the controller discriminate between valid
command sequences and the rare occasional false decode on.
voice.
These timers impose two simple but imponant requirements on
command entry:
. .
1) Command sequences can not be enteredv-e-r-y s-l-o-w-I-y,
because if more than four seconds elapses between digits, the
controller will disqualify the command.
2) Command sequences can not be entered at the beginning
of a long transmission, because if more than eight seconds
elapses from the last digit to the end of the transmission, the
sequence will be disqualified. A Touch-Tone command fol­
lowed by the Gettysburg Address will not be accepted.
