PURPOSE:To transmit data again from a radio transmission side, and to exclude the influence of a communication disturbance in a radio communication section by communicating the occurrence of the communication disturbance in the radio communication section by using an MODEM for installing a radio communication line. CONSTITUTION:This equipment is constituted of a facsimile 10 connected to a telephone line 1, and a communication module 18 to which a data terminal 19 is connected. Also, the equipment is equipped with FAX MODEM 3 and 13 which modulate and demodulate compressed facsimile data, MSK MODEM 5 and 16 which modulate and demodulate a control signal for installing the radio line, and radio transmitting and receiving parts 4, 6, 14, and 17. Then, the radio communication line is installed between the facsimile 10 and the communication module 18, and then the facsimile data are radio-communicated through the FAX MODEM 3 and 13. When the normal data can not received by the reception side, it is communicated from the reception side of the facsimile data to the transmission side by using the MSK MODEM 5 and 16. |
