  2. By enabling the group’s CTCSS tone
  3. By entering the group’s identification codeRichtige Antwort
  4. By inserting a five-pin, pre-programmed code plug

DMR routes audio by talkgroup, and a talkgroup is selected by its numeric identification code programmed into or entered on the radio. CTCSS tones belong to analogue FM, and the code plug is configuration data rather than a physical five-pin part.
