Claim:
1. A relaying device connecting wireless transceivers for audio communication therebetween through a plurality of relaying transceivers that are wired to the relaying device, comprising: a plurality of interfaces, each of the interface connecting to one of the relaying transceivers wherein the one of the relaying transceivers communicates with the connected wireless transceiver through their employed communication mode, further each of the interfaces inputting an uplink signal from the connected relaying transceiver and outputting a downlink signal to the connected relaying transceiver; a plurality of signal processing units, each of the signal processing units assigned to one of the interfaces, the one being defined as the assigned interface, and a plurality of mixers that makes the downlink signal, each of the mixers assigned to one of the signal processing units and connected to the other signal processing units, the one being defined as the assigned signal processing unit and the other being defined as remaining signal processing units, wherein when one of the signal processing units inputs an audio signal for communication from the assigned interface, the one of the signal processing units generates an audio detection signal, each of the mixers each of the signal processing units outputs a PTT signal to the assigned interface when a value of the ORed audio detection signal from the mixer to which the signal processing unit is assigned is positive, that is any one of the remaining signal processing units generates the audio detection signal, the PTT signal causing the relaying transceiver to transmit the audio signal, each of the interfaces outputs the PTT signal to the connected relaying transceiver when the PTT signal is input from the signal processing unit to which the interface is assigned, to cause the relaying transceiver to transmit the downlink signal, each of the mixers has a ON/OFF switch that is operated by a user, and when the switch is OFF, the mixer makes the downlink signal only by the signal received from the Internet not mixing the uplink signals from the remaining signal processing units, and when the switch is ON, the mixer mixes the uplink signals input from the remaining signal processing units and the signal received from the Internet to make the downlink signal.
