The tone signal receiver 12 of the marine telephone exchange 11 receives the facsimile communication end signal via the radio base station 10. Upon receiving the facsimile communication end signal, the central controller 13 closes the switch 14 and turns on the tone signal receiver 15. connection, and sends out a confirmation signal from the tone signal transmitter 16. When the confirmation signal is received by the tone signal receiver 5 of the additional device 3, the additional device 6 connects the switch 6.
switch to connect with telephone 1 and return to the talking state. The rest is the same as a normal ship phone. As a method for the additional device 3 to detect the start of facsimile communication, the additional device 3
There are two methods: a method in which the press of a mode switching button provided on the facsimile terminal is detected, and a method in which the additional device detects the press of the communication button of the facsimile terminal. Note that in the former method, it is necessary to press both the mode switching button on the additional device and the communication button on the 71-inch terminal. The latter method will be explained in detail below.

通話は行われずに終話となる。At the start of facsimile communication, when the mobile subscriber presses the communication button on the facsimile terminal 42, the facsimile terminal 42 switches to the telephone side 41 as shown in FIG.
3 to the central office line side, and in this embodiment to the facsimile side 414, the telephone side 413 detects the loop breakage.The loop detector 47 detects the loop breakage and identifies that it is time to start facsimile communication. A disconnection signal is notified to the control unit 48. When the control unit 48 receives the loop disconnection signal, it sends a disconnection signal reception function stop instruction signal to the mobile device 51, opens the switch 55, and stops the tone signal receiver 540 function for receiving the disconnection signal. . Simultaneously (control unit 4
8 is the switch 44' (c-opened), and the information line 412 indicating the on-hook or off-hook state of the telephone 41 is disconnected. (If the mobile subscriber goes on-hook at the start of facsimile communication, In order to prevent this, the control unit 48 also controls the 1-on signal transmitter 49.
, and sends a facsimile communication start request signal to the ship's telephone exchange. When the tone signal receiver 50 receives a confirmation signal from the ship's telephone exchange, the control section 48 switches the switch 45 to connect the facsimile terminal 42 and the mobile device 51 via the hybrid circuit 46, and facsimile communication is started. Ru. When the facsimile communication ends, the switch (corresponding to 33 in FIG. 3) of the facsimile terminal 42 switches from the facsimile side to the telephone side, so that the telephone side enters a loop state, and the loop detector 47 detects the loop. The control unit 48 identifies that the loop detector 47 detects a loop and that the facsimile communication has ended,
When the mobile device 51 sends a connection instruction signal to the tone signal receiver 54, the switch 55 closes and the tone signal receiver 54
is connected to the central office line. At the same time, the control unit 48 controls the tone signal transmitter 49 to transmit the message to the marine telephone exchange.
The tone signal transmitter 49 sends out a fax communication end signal. When the tone signal receiver 50 receives a confirmation signal from the ship's telephone exchange, the control unit 48 switches the switches 44° and 45t to connect the mobile device 51 and the telephone 41 to establish a telephone conversation state. Note that if the telephone 41 is on-hook when the telephone 41 and the mobile device 51 are connected,
The call ends without being made.

Even when modifying a facsimile terminal to connect to the switch 45, the central office line side of the facsimile terminal is short-circuited, and facsimile communication can be started and terminated by loop detection on the telephone side in the same way as shown in Fig. 4. This can be achieved by identifying the

といった利点がらる。As explained in the detailed description of the invention, during facsimile communication, both the mobile device and the exchange stop monitoring the mobile communication control signals. There is an advantage that facsimile communication can be performed even when the - parts of the control signals match. Furthermore, by installing additional equipment, facsimile terminals used in general telephone networks can be used as they are. Furthermore, just like normal facsimile communication, facsimile communication can be performed by simply pressing the communication button on the facsimile terminal, and if the subscriber puts the telephone on hook during facsimile communication, the facsimile communication will end immediately without making a call. This has the advantage that if you are off-hook, you can make a call again.
