Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a plurality of button telephones having a plurality of function button switches (hereinafter referred to as buttons);
The present invention relates to an electronic exchange system including an electronic exchange that controls communication of these plurality of button telephones.

[Technical background of the invention]

2. Description of the Related Art Recently, high-performance electronic switching systems have appeared in which a plurality of button telephones have a plurality of buttons and a plurality of service functions are assigned to the buttons. When multiple service functions are assigned to a button on a button telephone, the data is input by a maintenance person who uses an input device such as a keyboard to call up a maintenance program and assign data corresponding to the service function to each button. This was done by typing. In this case, confirmation as to whether the service function assigned to the button is in accordance with the request of the user of the button telephone is performed by the user actually executing the service function.

[Problems with background technology]

Therefore, in such a conventional electronic exchange system, each time the service function of the button is changed, the function of the button must be tested, which is troublesome. There was also the problem that the functional test procedure was complicated and difficult for users to memorize.

[Purpose of the invention]

This invention has been made focusing on the above-mentioned circumstances, and provides a highly practical electronic exchange system that allows a user to easily check the contents of service functions assigned to each button of a button telephone at a later date. It is an object.

[Summary of the invention]

Therefore, the present invention has achieved the above-mentioned object by displaying the content of the service function assigned to each button of the button telephone, that is, service function information, using a display means provided on the button telephone.

[Embodiments of the invention]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, and FIG. 2 is a diagram showing its operation flow. A plurality of key telephones 1a to 1n are connected to line circuits (LC) 2a to 2n of an electronic exchange 10, respectively. It is connected to the communication path network (SW) 3 via. Also,
The communication path network 3 is connected to the central office line via central trunk line trunk circuits (TRK) 4a to 4n. These communication path network 3, line circuits 2a to 2n, and office line trunk circuits 4a to 4n
is connected to a central processing unit (CC) 6 via a control data bus line 5, and is connected to a storage device (MEM).
Using the data stored in the key telephones 1a to 1, data is sent and received to and from the central processing unit 6, which performs various control operations, via the network 3.
1, and between the key telephones 1a to 1n and the central office line.

Now, as shown in FIG. 3, for example, the button telephone 1a is equipped with a handset 11, its hook mechanism 12, a dial mechanism 13, a service key (function button switch) 14 for performing various service functions, and a display 15. There is. Also, other button telephones 1n
etc. have a similar configuration.

The button telephones 1a to 1n are placed in a functional test mode (hereinafter referred to as test mode) by performing a "special dial" operation or operating a dedicated switch on the key telephones 1a to 1n. is set to Here, if the button telephone 1a performs a "special dial" operation, information (data) indicating this is transmitted from the button telephone 1a via the line circuit 2a and through the data communication path via the control data bus line 5. , and sent to the central processing unit 6. This central processing unit 6 compares the data obtained from this control data bus line 5 with the "special dial" data stored in the storage device 7, and if they match, the key telephone 1a is activated. The test mode is set and then the test mode routine stored in the storage device 7 is operated. In this test mode, the button telephone 1a is in an unregistered state, so it cannot be called by the other key telephones 1b to 1n, and is also in a state where it is unable to make a call.

In the above state, key telephone 1a is pressed with service key 1.
When you press 4, the information is transferred to control data bus line 5.
The data is transmitted to the central processing unit 6 via the . Then, the central processing unit 6 searches the data stored in the storage device 7 for service function information corresponding to the key 14, and then operates according to the display routine stored in the storage device 7. Central processing unit 6
has a function of converting data (service function information) into alphanumeric data for display, and sends alphanumeric data corresponding to the data to the control data bus line 5 in this display routine. The button telephone 1a then receives the alphanumeric data and displays alphanumeric characters corresponding to the function on the display 15.

Thereafter, each time each button is pressed, the function name (service function information) corresponding to each button is displayed on the display 15.

Next, the button telephone set 1a returns from the test mode to the normal call processing mode by, for example, operating the release key 14a. That is, based on the information obtained through the control data bus line 5, the central processing unit 6
This is done by detecting that the test mode setting of the key telephone 1a has been canceled, returning the key telephone 1a to the normal call processing mode, and enabling incoming and outgoing calls.

〔Effect of the invention〕

As explained above, according to the present invention, a user can easily check service function information assigned to a plurality of buttons by simply accessing it from a button telephone, and there is no need to perform a function test. There is no need for maintenance personnel to be involved unnecessarily. Furthermore, in the test mode, the outgoing and incoming calls of the corresponding key telephone are restricted, so that functional tests can be carried out reliably and unnecessary call processing control can be prevented.
