Then, when the other party responds to the call from the ISDN, an incoming response message is sent to the terminal device as the caller. In this way, the line connection is completed, a call through the B ₁ channel is executed. Then, the user announces that the data of the FD will be transferred from now on, and the communication partner changes the reception FD to the FDD of the destination terminal device.
Check that the camera is attached to the camera and press the start button STK. The pressing operation of the start button STK is detected by the processor 6 via the operation unit 4. As a result, the processor 6 issues a request to the FDC 3 for reading data to be transferred. Then, a procedure for establishing a connection with the same destination terminal device that is currently making a call using another channel is performed between the terminal device, the ISDN, and the destination terminal device. As a result, the terminal apparatus and the ISDN through both B ₁ channel and B ₂ channels
Are connected. Then, the communication control unit 1 requests the ISDN to establish a data link in the ABM mode (asynchronous equilibrium mode) and request a response from the partner (the P bit for response invitation is “1”). SABM command) is sent. If the destination terminal is
UA.F when it is possible to respond to communication in ARM mode
A command (a UA command in which the F bit permitting a response is “1”) is sent from the destination terminal device. Thus the terminal device and the other party to the data link through the B ₂ channel is established between the terminal device, the data stored in the FD I
It can be transferred to the destination terminal device as a frame (information frame). The data read by the FDC 3 is assembled as an I frame via the communication control unit 1 and transferred to the destination terminal device via the ISDN. In addition,
The applicant of the present invention filed an application for this FD data transfer procedure in Japanese Patent Application No. 2-101226. Now, when the user presses the display switching button Ki + 1,
When the switch KSi + 1 is turned on, the storage information of the toggle flip-flop TFF is inverted, and the display information SB ₂ (1), S

As a result, as shown in FIG. 4 (b), shows the unit number of the FDD in transit "FD-1", indicating that a communication status display regarding B ₂ channels "B2", the communication terminal device A bar graph indicating the amount of data that has been transmitted, indicating that the caller is the caller, “1234567890”, the current FD data is being transmitted, and a bar graph indicating the amount of data that has been transmitted. Is displayed on the LCD 5b. In FIG. 4 (b), the display "CMP" indicates that the data is compressed and transferred, and the display "VRF" indicates that the other party writes the reception information and the FD when the reception information is written to the FD. It means that a verify operation for collating with the information is being performed. While there has been described the case the terminal device is a calling party, if the terminal device is a called party, one of the B ₁ channel or B ₂ channels in the terminal device is used for outgoing and the other for incoming The same applies to the case where the function instruction button Ki + 1 for switching the display is used.
By the operation of, the channel for displaying the communication state is switched, and the communication state of each channel is displayed on the LCD 5b.

Second Embodiment Next, a second embodiment of the present invention will be described. In the first embodiment, the channel to be displayed is switched by toggling the toggle flip-flop TFF of the display unit 5. In this embodiment, the display is switched by software executed by the processor 6. In this software, a display management flag is used to store a channel to be displayed at the present time. The other parts have the same configuration as that of the first embodiment. When the function instructing button Ki + 1 for display switching is pressed down and the pressing operation is detected by the processor 6 via the operation unit 4, the processor 6 executes a routine whose flow is shown in FIG. First, the process proceeds to step S1, it is determined whether or not using the B ₁ B ₂ both channels. And the judgment result is "YE
In the case of "S", the display management flag at the present time is referred to (step S3), the display management flag is inverted, and
The display information of the channel corresponding to the inverted display management flag is sent to the LCD 5b. On the other hand, if the judgment result of step S1 is "NO", the flow proceeds to step S2, and in use one of B ₁ channel or B ₂ channel, and determines whether it is in FD media conversion. Here, the FD media conversion is performed by attaching each FD for performing media conversion to each of the two FDDs and pressing a function instruction button Ki (see FIG. 1) for instructing the FD media conversion, whereby the FDC3 (FIG. 1) is pressed. See). If the result of the determination in step S2 is "NO", the processing of this routine ends. That is, when B ₁ if none of the channel and B ₂ channel is not used, or not being a media conversion even during use one of the channels,
The operation of the function instruction button Ki + 1 for switching the display is invalidated. Therefore, occurrence of useless switching processing is prevented. If the result of the determination in step S2 is "YES", steps S3 and S4 are executed, and the channel to be displayed is switched. In this case, before pressing the function instruction button Ki + 1, a busy using, for example, B ₁ channel, and,
