How does a half-duplex radio set access a full-duplex telephone network?
Devices such as trunking radio sets and radio sets only transmit while the push-to-talk button is held, so they originally could not intercommunicate with the full-duplex calls of a telephone network.
Devices such as trunking radio sets and radio sets only transmit while the push-to-talk button is held, so they originally could not intercommunicate with the full-duplex calls of a telephone network. The EMVOICE24 interface of the IDM MAP4E1-30 hardware voice conference device can directly connect devices such as radio sets, trunking intercoms and access control intercoms, and the optional voice-triggered communication activation function provided by the conference room brings half-duplex communication devices into full-duplex communication networks such as telephone networks; calls from on-site radio sets can be brought into the conference call at the command center, and the voice from the command center can also return to the on-site radio sets. A conference room can not only access local terminals, but can also transmit to other local audio interfaces over the E1 interface, and the conference rooms of multiple devices can be directly stacked into one large conference room.
