PURPOSE:To transmit the output data of digital data equipment through a sound communication circuit without converting data through an acoustic coupler by transmitting/receiving data between a telephone set and the digital data equipment by a radio system. CONSTITUTION:When data is transmitted, the digital data equipment 10 and a radio transmitter 11 are powered on and further a connecting device 9 is put in operation to put the transmission of the signal of a radio receiver 8 to a subscriber telephone circuit 2 in readiness. Consequently, the output data of the equipment 10 is sent to digital data processing equipment 7 such as an electronic computer through the radio transmitter 11, radio receiver 8, connecting device 9, subscriber telephone circuit 2, telephone network 1, public communication circuit 4, network controller 5, and modem 6. Further, the connecting device 9 is put in reverse operation to send a speech signal through a handset. |
