Tetra operating modes

In TMO mode, there is the single connection between two communication partners, the direct call, and the connection with a group, the group call. The single call operates in duplex, so that everyone can talk and receive at the same time, whereas the group call operates in half-duplex. In this mode, specific groups can be addressed, for example, for use in fire or emergency situations.
