Reference numeral 17 is a signal transmitting / receiving circuit, 17 is a communication path for exchanging each communication signal, and 18 is a tone generating circuit for generating various tones such as ringing tones and busy tones.

[Display of Master Telephone Number (FIG. 2)] Next, the process of displaying the extension number of the extension-only telephone currently designated as the master telephone (hereinafter referred to as the master telephone number) will be described with reference to the flowchart of FIG. A description will be given below according to the chart.

The master telephone number can be displayed from each extension-only telephone 1 that is connected, and is displayed on the liquid crystal display unit 2 of the extension-only telephone 1 that has performed the operation.

The master telephone No. display function is operated by operating a “setting key” preset in one of the function keys 4 of the extension telephone 1 and then the dial key 3 is used to display the master telephone No. display function. It is started by operating the special number.

First, in step S21, C is waiting for a key input.
When the PU 13 receives, via the control signal transmission / reception circuit 12, a "setting key" from the extension-only telephone 1 that makes a display request for the master telephone number, the process proceeds to step S22. Then, in step S22, the special number is received from the dial key 3 of the same extension-dedicated telephone 1 into which the "setting key" is input. Then, if the received special number is the master telephone number display request, the master telephone number in the RAM 15 is processed in step S23.
Read the master telephone number stored in the area. However, when a special number which is not the master telephone number display request is received, each functional process corresponding to the special number is performed.

Next, in step S24, the master telephone number is instructed to the control section 7 of the extension telephone 1 so that the master telephone number is displayed on the liquid crystal display section 2 of the extension telephone 1 which has made the request. Upon receiving this instruction, the control unit 7 of the extension telephone set 1
A display message such as “master phone No.:21” is created and output to the liquid crystal display unit 2. The display message may be "21" only.

As described above, the master telephone number is displayed on the liquid crystal display portion of the extension-only telephone by operating the master telephone number display request from one of the extension-only telephones having the liquid crystal display portion. The advantage is that the extension number of the master telephone can be easily known.
