Abstract
PURPOSE:To display the audio interruption from the third party together with the data without interferring the data communication, by providing the communication information channel separately with the data transmission communication channel. CONSTITUTION:Separately with the communication channel, the communication information channel is provided within the audio band in 4kHz. Further, when the audio incoming interruption request is present, it is instructed that the signal fs is transmitted via the communication information channel to the control circuit 12 at the converter side. This signal fs reaches the subscriber circuit and it displays the presence of interruption to the display 8 through the control of the controller 7 via the frequency selection circuit 6. Further, when a telephone set is used, the incoming interruption information can be audible from the receiver as audible signal.
