Normalization Bit (NB)
Break Signal (BREAK)
Start-of-Frame Symbol (SOF)
End-of-Data Symbol (EOD)
End-of-Frame Symbol (EOF)
Inter-Frame Separation Symbol (IFS)
Idle
The NB symbol has the same property as a logic 1 or a logic 0. It is
only used in IFR message responses.
The BREAK signal is defined as a passive-to-active transition
followed by an active period of at least 240 s (see
The SOF symbol is defined as passive-to-active transition followed by
an active period 200 s in length (see
data bytes which follow the SOF symbol to begin with a passive bit,
regardless of whether it is a logic 1 or a logic 0.
The EOD symbol is defined as an active-to-passive transition
followed by a passive period 200 s in length (see
The EOF symbol is defined as an active-to-passive transition followed
by a passive period 280 s in length (see
byte is transmitted after an EOD symbol is transmitted, after another
80 s the EOD becomes an EOF, indicating completion of the
message.
The IFS symbol is defined as a passive period 300 s in length. The
20- s IFS symbol contains no transition, since when it is used it
always appends to a 280- s EOF symbol (see
An idle is defined as a passive period greater than 300 s in length.
