[Embodiments of the invention]

An embodiment of the present invention will be described in detail below based on the drawings.

FIG. 1 is a schematic diagram of a private branch exchange system according to this embodiment, in which a private branch exchange circuit 1 has standard telephones 3. A multifunction telephone 51 and a display equipped multifunction telephone 817 each connect to a subscriber circuit 9.
．． Connected via 11.13. A central control unit 15 and a memory 17 are also connected to this private branch exchange circuit 1. The central controller 15 not only controls the private branch exchange circuit 1 but also writes and reads data in the memory 17. The memory 17 stores the telephone number of each telephone 3, 5, 7, the service type to be set, etc. in a format to be described later.

The display-equipped multifunction telephone 7 is provided with a display (not shown) made of liquid crystal, and the contents of the memory 17 are displayed on this display according to commands from the central controller 15.

FIG. 2 is a table showing the data structure stored in the memory 17, and this memory 17 contains the data length, telephone number, and service type set for each telephone 3, 5, and 7. be remembered. Note that as many service types as there are service types set for the telephone are stored.

For example, in FIG. 2, there are three types of services set for telephone 3, and one type of service set for telephone 5.

Next, the operation of this embodiment will be explained. FIG. 3 is a flowchart of the operation when setting the service function from each telephone.If the telephone is a standard telephone 3, the user dials a special number, and if the telephone is a multifunction telephone 5, the user dials a special number. When the key operation is performed to input service function settings (step 301), the central control unit 15 detects the telephone number of the telephone and the service type to be set (step 303), and then searches the memory 17. It is checked whether the telephone number exists in the memory 17 (step 305), and if the telephone number is present, it is checked whether the service function to be set this time is already in the memory 17 (step 307), and If the service function to be set this time is not in the memory 17, the service type is written in the memory 17 (step 309). At this time, the data for that Kawasaki is sequentially rear-aligned and shifted.

If it is determined in step 305 that there is no telephone number of the entered telephone in the memory 17, the data length, telephone number, and service type are written in the last part of the data in the memory 17 according to the format shown in FIG. (Step 311
).

FIG. 4 is a flowchart for canceling the service function from the telephone. The user manually inputs the dial or keys to cancel the specified service function from the specified telephone (
In step 401), the central control unit 15 detects the telephone number of the telephone and the service type to be set (step 403), and then searches the memory 17 to check whether the telephone number is in the memory 17 (step 403). Step 405),
If there is that phone number, it is checked whether the service function to be canceled this time is already in the memory 17 (step 407).
, if the service type is already in the memory 17, the service type is canceled (step 409).

If the corresponding telephone number and service type are not found in the memory, the process is immediately terminated.

Is Figure 5 a multi-function phone with a display? ! ! This is a flowchart when requesting display from 7, and when you want to know the setting status of the service type of one telephone in this multi-function telephone 7 with a display, you dial "special number dial 10 telephone numbers" and all If you want to know the setting status of the service type of your phone, press "Special number dial" - "Special number"
Dial.

When a special number dialer telephone number is dialed (
In step 501), the central control unit 15 detects the corresponding telephone number, searches the memory 17, and reads the service type for the corresponding telephone (step 503).
Step 505), and display this on the display (Step 507).

This display is displayed on the display 19 of the display-equipped multifunction telephone B117 in the format shown in FIG.

In other words, one display shows the telephone number of the telephone ('12 in the figure).
34') and the service type set on the telephone is a predetermined code ('CFD' in the figure).

'DND', 'ACB'), and if a large number of service types are set and cannot be displayed in one line on the display 19, C' is displayed in the rightmost column.

If this C' is displayed, special key (for example 1##)
If you enter , the following service types will be displayed.

Returning to the flowchart of FIG. 5, if there is no special number dial + telephone number dial input, but there is a special number dial + special number dial input (step 509), the central control unit 15 searches the memory 17 and searches the memory 17 for a telephone number with a small number. Rearrange the rows in order from top to bottom and display them according to the format shown in Figure 6.

Therefore, by making a display request from a multi-function telephone with a display device, the user can know the service types set for a particular telephone or all telephones.
