Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electronic button telephone device housing a button telephone equipped with a separate extension calling button (DSS button) and a character display.

(Prior Art) Conventionally, in this type of button telephone, when the individual extension call button is pressed, the display on the button telephone does not respond, and the next operation of the handset shifts to the operation of calling the extension. or has a function to display an extension number and move to an extension number confirmation operation when the above-mentioned call button is pressed.

(Problem to be Solved by the Invention) If the button telephone has the former function, when the individual extension button is pressed down, nothing appears on the display, but when the handset is operated, the extension calling operation starts. Therefore, there is a drawback that the telephone operator is likely to make an erroneous operation of calling another key telephone by mistake.

If the latter function is provided, the extension number of the key telephone can be confirmed when the individual extension button is pressed, but the extension number will not be called directly even if the handset is operated thereafter.

It has the disadvantage that the individual extension calling button must be pressed again for the extension calling operation.

Furthermore, there is a problem in that, regardless of whether the former or the former switches to an extension calling operation, if the called button telephone is in a busy mode such as a busy mode, the calling button telephone cannot make an extension call.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic key telephone device that prevents erroneous operation of an individual extension calling button and simplifies the calling operation by notifying in advance the number and status of the key telephone to which an extension call is to be made. There is a particular thing.

(Means for Solving the Problems) In order to achieve the above object, the electronic key telephone device according to the present invention is a key telephone device that accommodates a key telephone device equipped with a plurality of individual extension call buttons and a character display. The device includes a telephone status memory that stores the current state of each button telephone, a telephone interface that sends and receives data and call numbers to and from each button telephone, and a telephone interface that connects the button telephone and an extension line via the telephone interface. and a communication path switch that stores the current status of each telephone in the telephone status memory, receives information sent by pressing an individual extension button via the telephone interface, and stores the current status of each telephone in the telephone status memory. and a control unit that performs control to read out information on the current state of a designated telephone, send it to the button telephone whose individual extension button is pressed, and display it for a certain period of time, and each of the button telephones a data interface for transmitting and receiving data and call signals to and from the interface; a key input unit that corresponds to a pressing operation of the individual extension call button; a display control unit that controls the character display; When key data is input from the key input section by pressing the call button, the information is sent to the main device, and when display information is sent from the main device, this display information is used to control the display control section. and a control section that displays the text on the character display and controls the extension calling operation to the designated telephone by off-hooking the handset and receiver.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an electronic key telephone device according to the present invention, and FIG. 2 is a front view of the main body of the key telephone used in the embodiment of the present invention.

The button telephones #1, ..., #N have a handset 21,
Dial 22, outside line button 23, outside line lamp 2
4. Character display 25 and individual extension call button 2
6 on each front.

In FIG. 1, the main device uses the button telephones #1, . . . , #N shown in FIG. Telephone interface 1 for sending and receiving data and voice signals
2. It includes a communication path switch 13 that connects the key telephone and an extension communication path, and a main control section 14 that controls each part in the main device of the key telephone.

Each button telephone also includes a data interface 15 that sends and receives data and voice signals to and from the main device, a key input section 16 that notifies the internal CPU of each button operation on the button telephone and the operation of the handset, and characters (not shown). It includes a display control section 17 that controls a display, etc., and an internal CPU 18 that controls each section within the button telephone. When you press a certain button on a certain button telephone,
The key input unit 16 notifies the telephone CPU 18 of the key input. When the CPU 18 in the telephone determines this key input, it converts it into data and sends the main data (key data) to the main device through the data interface 15.

In the main device, key data sent from the key telephone is sent to the main control section 14 via the telephone interface 12. The main control unit 14 is
A well-known key data analysis process is performed to control the corresponding parts in the main device, and a visible and audible instruction is sent to the corresponding key telephone via the telephone interface 12. Then, the new state of the corresponding button telephone is stored in the telephone state memory 11. Now, a case will be described in which the button electronic device #1 of extension number #1 presses, for example, the extension individual call button 26 corresponding to extension number #2.

According to the above operation, press the designated extension individual call button 2.
The key data corresponding to 6 is the main control unit 14 in the main device.
sent to.

At this time, the main control unit 14 reads data indicating the current state (state data) from the memory specifying the button telephone #2 corresponding to the main key data in the telephone state memory 11, and reads the state of the key telephone #2 through the telephone interface 12. Send data to operation button telephone #1.

Therefore, the CPU 18 in the telephone, which received this status data through the data interface 15,
Since a command to display the status is issued to the display control unit 17, the display control unit 17 controls the character display 25 to display a display corresponding to the specified status data for a certain period of time.

An example of the display on the character display 25 in FIG.
This indicates that the button on the operated extension number #2 is in use for an outside line call.

Next, after this state, when the handset is lifted up, the operation immediately proceeds to calling the extension of the key telephone displayed on the character display 25. However, in this example, the designated key telephone #2 is already in an outside line call (busy state), so the operating telephone only receives the conventional busy tone and does not make an extension call.

If the above-mentioned display indicates that the button telephone corresponding to the pressed button is in the "idle" state, when the handset is raised, the main control section 14 in the main device will switch the communication path switch 1.
3, and connects the operation button telephone #1 (calling button telephone) and the called button telephone #2 to the extension communication path, thereby enabling an extension calling state.

(Effects of the Invention) As described above in detail, the present invention is configured such that when an individual extension button is pressed, the extension number of the button telephone corresponding to that button and its current status are displayed on the character display. By this,
To confirm the number of a button telephone to which an extension call is to be made and to notify in advance whether or not an extension call is currently possible to a button telephone operator. After the above-mentioned operation, by off-hooking the handset, the system can automatically shift to an extension calling operation.
