3.4.5 Private Call
The Private Call, also called point-to-point, or individual call, enables calling between two individuals. No other
radio can hear the conversation. This call type can be carried out in two ways:
• Duplex call (if the system allows), in TMO Mode. Both parties can speak at the same time.
• Simplex call, in TMO or DMO Mode. Only one party can speak at a time.
When a DMO Private Call takes place, radios not involved in this call receive the channel busy indication. The
radios are identified using its radio numbers.
3.4.6 Communication through Repeater
Radios that cannot communicate directly between each other in DMO Mode, can do it through the repeater that is
attached on the same talkgroup. This connectivity is used to enhance the radio DMO area.
