DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 and 2 are diagrams showing an embodiment of a telephone device according to the present invention. In this embodiment, parts that are the same as those in the conventional example are designated by the same reference numerals, thereby omitting redundant explanation.

The telephone device according to this embodiment includes an MF receiver circuit 11 that can be connected to a central office line communication path, and an external memory input/call button 1 that can perform memory input and call operations.
A button telephone 13 having a button telephone number 2 is provided. The other configurations are the same as those of the conventional telephone device.

The external memory input/call button 12 of the button telephone 13 allows input of dial number data from the outside into the dial memory 8 of the other party's button telephone during a call, and when the own button telephone makes a call, the dial number data can be inputted from the outside. It functions as a key means for performing operations.

The operation of the telephone device having such a configuration will be explained. In this embodiment, the processing procedure for dial memory external input operation is shown in FIG.

Initially, the key telephone 13 is in a talk mode (step 31), and the talk path 6 is connected to the key telephone 13 through the key telephone interface 5. During this call mode, the CPU 10 checks whether or not the external memory input/call button 12 for dial memory input has been pressed (step 32). and,
When the external memory input/call button 12 is pressed, the call link unit 7 is activated to connect the communication path 6 with the other party's telephone to the MF receiver circuit 11 (step 33), and an MF signal is sent from the other party. wait for. Here, at the other party's telephone, the operator key-inputs the dial to be registered, and this input data is sent through the public line 2 as an MF signal. After the processing in step 33, this telephone device receives the MF signal sent from the other party (step 34). The dial information obtained by receiving this MF signal is sent to the CPU 10 (step 35
