Section 171.311

(h) TDM cycle. The time periods between angle transmission sequences
must be varied so that exact repetitions do not occur within periods of
less than 0.5 second in order to protect
against synchronous interference. One

such combination of sequences is
shown in Figure 4 which forms a full
multiplex cycle. Data may be transmitted during suitable open times
within or between the sequences.
