The operator can place the channel for the currently used voice call on hold and respond to the next incoming voice call. First, for this purpose, the other party of the voice communication channel in use is instructed to be put on hold, and then, for example, a hold key is input from the keyboard 8. As a result, the voice communication channel used so far is put on hold.

Next , for example, a response key is pressed from the keyboard in order to connect to a voice communication channel to which a call has been received later. Accordingly, the microprocessor 3 controls the communication control unit 5, sends a response message to the network, and switches the data channel to the voice call channel that was called later. Thereafter, the operator uses the handset 4 to make a voice call. After the end of the call, the operator presses, for example, a switching key from the keyboard 8, whereby the microprocessor 3 controls the communication control unit 5 to switch the voice communication channel to the data channel of the other party who was initially performing the voice communication. . As a result, the operator can make a voice call with the other party who made the voice call first. Similarly, the microprocessor 3
Connection and switching control are performed for incoming calls of n data channels.

As described above, in the first embodiment, when there is an incoming call exceeding the number of data channels that can be handled by the terminal device, the communication control unit uses the call control channel to switch the data channel. By switching and using, there is an advantage that the terminal device can use more channels than can be handled simultaneously.

Next, a second embodiment will be described with reference to FIG. EXAMPLE shown in FIG. 2, at the same time managing the number of data channels that can be handled, a call control according to the incoming and outgoing call between exchanges mutually, and a communication control unit 5 for switching of data channels made as required When there is an incoming call exceeding the data channel that can be handled at the same time , R as a memory for temporarily storing the caller subscription number and the caller terminal type.

Next, a control operation of the terminal device according to the present embodiment will be described. First, the communication control unit 5 extracts the caller's subscription number and caller terminal type sent from the exchange at the time of the incoming call, and temporarily stores them in the RAM 11. Next, after the end of the communication, the data stored in the RAM 11 is read out by the microprocessor 3 and passed through the display control unit 2 to the CR.
Displayed on T1. Next, the operator determines whether to store the displayed data such as the subscriber number in the database 12. Next, a key operation is performed from the keyboard 8 to determine whether or not to register it in the database. When registering in the database 12, an ID code is input from the keyboard 8. The microprocessor 3 confirms that the same caller subscription number is not already registered in the database 12 by the operation, and then registers the same in the database 12. If the same caller subscription number has already been registered, an error code is displayed on CRT1. Similarly, each time a call is received, the subscriber's subscription number is recorded on the database 12 together with the inspection ID.

Next, at the time of calling, if the subscriber number is registered in the database 12, the microprocessor 3 searches the database 12 by inputting the ID code added at the time of registration from the keyboard 8. Then, the corresponding subscriber number is displayed on CRT1.

After confirming the subscriber number displayed on the CRT 1, the operator performs a key input from the keyboard 8 to perform a calling operation.

If the microprocessor 3 searches the database 12 and there is no corresponding subscriber number, that is, if the subscriber is not a registered subscriber, the subscriber 8 inputs all the subscriber numbers of the called party from the keyboard 8. I do. The communication control unit 5 performs a calling operation to the communication line 6 based on the inputted subscriber number.

After the communication is completed, the operator inputs the ID code from the keyboard 8 to add a search ID code to the subscriber number and record the ID code on the database 12.

The input ID code is searched and compared by the microprocessor 3 to see if the same code has already been registered in the database 12. If there is the same code, an error message indicating that the same code has already been registered is displayed. If the code is a new code, the microprocessor 3 records the ID code, subscriber number, terminal type, and the like in the database 12 by key input from the keyboard 8. Similarly, at the time of calling, if the subscriber number of the called party is new, an ID code is added to the subscriber number and registered on the database 12.

As described above, in the second embodiment,
By extracting the subscriber's subscription number and terminal type sent from the exchange at the time of an incoming call, adding an ID code and registering it in the database, the advantage is that the calling operation can be performed only by inputting the ID code at the time of calling.
