I/Push To Talk

I/Push to Talk (I/PTT) interfaces to a radio system controller over a network connection (TCP/IP) or a serial (RS-232) connection to provide PTT information to a dispatcher workstation. Each time a radio unit in the field transmits to the dispatch environment, the identification of the transmitting unit is displayed in a special area (banner) on the dispatcher’s workstation monitor. I/PTT also supports a Unit Emergency signal from a PTT radio.
