Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention relates to a telephone system such as a button telephone device or a private branch exchange, and more specifically, to a telephone system in which an extension telephone is connected to an extension telephone. The present invention relates to a telephone system that displays an appropriate and easy-to-read display indicating whether or not an extension is connected or the status of an extension telephone connected to an extension.

(Prior Art) FIG. 6 shows a button telephone device as an example of the above telephone system. The main device 101 includes a plurality of button telephones, 1021..., 102. .

..., 1021Il are connected, and a plurality of office lines 1031゜...103j, ..., 103. is connected. Button telephone 1021. ...,
102. ,..., 102II, is the central office line 103
1, . . . , 103j, . . . , 103n. In this system, for example, when you make a call using an extension from a certain key telephone, if the called party's key telephone is in use or the extension is not receiving calls, a busy tone is returned to the calling party's key telephone. be done. In this way, if the state of the other party's key telephone connected to the extension is not known, the call will be made in vain.

Therefore, there are systems in which a telephone with a busy indicator (BLF) is used as a button telephone, or a central reception device is used. The telephone directory with busy indicator is telephone 131200 as shown in FIG. This telephone 9200 is provided with LEDs 201 corresponding to the extensions of the system. 202 is a dial key, 203 is a key for selecting a central office line or an extension line, and 204 is an LED for display corresponding to the key 203 for selecting a central office line or an extension line. When using this telephone 3200, if the key telephone connected to the extension is in use,
Since the corresponding LED 201 lights up, you can know the status of the other party and avoid unnecessary calls.
However, according to this phone FA200, LED2
Since 01 indicates the state of the extension telephone, the only way to do this is to turn on, blink, or turn off the LED 201, and the number of states that can be represented is limited. Even if the blinking cycle is changed to represent the state, there is a drawback that it becomes difficult to understand when the number of states increases.

Furthermore, when a telephone is not connected to an extension, the LED 201 corresponding to that extension is turned off, which has the disadvantage that the display becomes similar to that of a telephone that is not in use. On the other hand, the central reception device has an extension line and one-on-one
A corresponding LED is provided, and a button is provided corresponding to each LED, and by operating this button, the button telephone directory (extension telephone) connected to the corresponding extension can be called with one touch. . However, even with this centralized reception device, the status is displayed using LEDs, so it has exactly the same drawbacks as the telephone with a busy indicator. Furthermore, central reception devices are generally used for exchanges, etc., and are special devices such as those equipped with a button that calls an extension telephone with one touch, as described above, so they cannot be used as normal extension telephones. As a telephone, it had the problem of being difficult to use.

(Problems to be Solved by the Invention) As described above, in the conventional telephone system, the status of an extension or an extension telephone is displayed using lamps such as LEDs, which limits the number of statuses that can be displayed. When the number of states is increased, there is a drawback that it becomes difficult to understand which state is being displayed. The present invention was made in view of the shortcomings of the conventional telephone system, and its purpose is to appropriately display the status of an extension or an extension telephone, and to make it difficult to understand even if the number of display statuses increases. It is an object of the present invention to provide a telephone system capable of displaying information such that the information is not displayed.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides an extension telephone with a display equipped with a display capable of displaying characters or symbols, and whether or not the extension telephone is connected to the extension. a detection means for detecting the operation status of the extension telephone connected to the extension or the extension telephone connected to the extension; A telephone system is constructed by equipping the display of the telephone with display control means for displaying characters or symbols.

(Function) According to the above telephone system, the status of each extension or the status of the extension telephone connected to that extension is displayed in characters or symbols on the display of the extension telephone with display, corresponding to each extension. Therefore, it is not only easy to understand, but also adaptable to an increase in the number of display states.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of essential parts of an embodiment of the present invention. In the figure, 1 indicates a main device, and 2 indicates an extension telephone with a display (key telephone).

The extension telephone 2 with a display device is constructed as shown in FIG. On the top surface of this extension telephone with display 2, there is a key 21 for selecting a central office line or extension, and an LED corresponding to this selection character -21.
22, a dial key 23, and a display section 24 consisting of a plurality of liquid crystal matrix patterns. Display section 2
Each of the four liquid crystal matrix patterns has a configuration in which one character is displayed using 5×7 dots.

The number of liquid crystal matrix patterns is equal to the number of extensions (16) of the button telephone. An extension phone with a display like this! A2 is connected to the key telephone interface 3 in the main device 1. There are 14 sets of button telephone interface 3 and extension telephone with display 2 (not shown in the figure). Therefore, the number of extensions is 16.
Therefore, no extension telephone with display device is connected to the two extensions. A button telephone interface 3 is connected to a bus 4. Connected to the bus 4 are a CPU 5 that centrally controls the entire system, a ROM 6 that stores programs and data used by the CPU 5, and a RAM 7 that the CPtJ 5 uses as a working register. Note that the main device 1 is also provided with a crosspoint, a central office line interface, etc., but these are not directly related to the present invention, so their description will be omitted here.

In accordance with the program of the flowchart shown in FIG.
is displayed on the display section 24 of. The display operation will be described below using the display examples shown in FIGS. 4 and 5. (In the figure, a telephone with a display device is simply referred to as a telephone.) First, when the button telephone device is powered on, the hardware is reset in initial processing (301). After performing initial processing such as the above, the process moves to input processing (302) in which inputs are received by operating the dial keys 23 and the like. In this embodiment, the processing is shown for only one extension telephone 2 with a display, but as mentioned above, there are 14 extension telephones 2 with a display, so the processing is performed for each one. ing. Input processing (
302), the result is whether an extension telephone with a display is connected to the extension, and there is an input on the extension telephone with a display N (N is an extension from "10" to "25"). 303), if there is an input, the status of the extension telephone with display N (busy, extension call rejected, extension call forwarding, etc.) and the extension status are determined by the input. and stores the status data in RAM.
7 (304). This state detection is carried out by the CPLJ 5 via the bus 4 and the button telephone interface 3, and if the state detection is performed for all extension telephones 2 with display devices, data for display will be available. Then, the CPU 5 sets the state data (30
4) In the telephone processing (305), processing -m--for example, sending dial number data corresponding to the input dial key number--is carried out for the corresponding extension telephone with display device N. Return to input processing (302).

On the other hand, as a result of detecting whether there is any input on the extension telephone with display IN (303), if there is no input, it is detected whether the display mode is the extension telephone status display mode (30B). This mode switching is assumed to be performed by a switch (not shown) of the extension telephone with display 2 shown in FIG. In the above mode detection, when the extension telephone status display mode is detected, the CPU 5 searches the RAMT for status data of all extension telephones, and
A display as shown in FIG. 4 is made on the display unit 24 of the extension telephone with display device N (307). In FIG. 4, the numbers "10" to "25" attached to the outside of the display section 24 are extension numbers. The display section 24 shown in FIG. 4 shows that of an extension telephone with a display to which the extension number "10" has been assigned (that is, the LC of the own device's extension number "10").
D is not displayed. ). However, the reason why you don't display your own phone is because the display will be the same as other free phones, so it is necessary to display the display that it is your phone (
For example, it is better to display the status in the same way as the others.
-LCD2425 is associated. In the display in FIG. 4, extension numbers "11", "18", "20"
” indicates that the telephone extension with display is busy (indicated by “B”), and extension numbers “15” and “16” are busy.
” indicates that the extension telephone with a display is set to reject incoming calls (indicated by rDJ), and the extension number “23” is displayed.
This indicates that the extension telephone with display is in the process of forwarding calls (indicated by a "T"), and the extension number "24" is being forwarded.
”, there is no telephone connected to the extension “25” (“
-" is indicated. ), and other extension telephones with display devices are in the unlisted state.

In addition, when detecting the display mode (306), if it is detected that the extension phone status display mode is active, the CPU
5 detects time data from a timer (not shown), and based on the detected time data, displays a calendar as shown in FIG. 5 on the display section 24 of the extension telephone with display device N (308).

The example in FIG. 5 shows December 25th, 15:30. In this way, according to this embodiment, the status of each extension or extension telephone can be precisely and appropriately grasped.

In this embodiment, the display mode is switched using a switch (not shown), but the display mode may be switched by operating the dial keys 23 or the like in a special order. Further, one of the office line/extension line selection keys 21 may be used as a switching key. Further, in this embodiment, the LCD is provided with a number of extensions, but for example, 1
In the case of 1g, the status of the extension or extension telephone may be displayed by scrolling the display by button operation or the like. Furthermore, in order to detect the extension status, there is no need to detect through the button telephone interface 3 that an extension telephone is not connected to the extension, but it is provided as data in the ROM 6 in advance, and this is detected. You can also do it.

[Effects of the Invention] As explained above, according to the present invention, the status of an extension or an extension telephone is displayed with characters or symbols, so the status can be displayed appropriately, and even if the number of displayed statuses increases, It has the advantage of being easy to understand.
