Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention provides a control unit in the main device for connection to the main device by giving a signal from a switch that switches between a call processing mode and an operational data setting mode. The present invention relates to an improvement of an electronic button telephone device that allows operation data to be set using a specific button telephone set.

[Technical background of the invention]

The conventional electronic button telephone device as mentioned above,
This will be explained with reference to FIG.

In FIG. 1, 1 indicates the main device. A control section (hereinafter referred to as CPU) 12 is provided within the main device 1, and the CPU 12 performs overall control of the electronic key telephone device according to a program in its own memory. In addition, a changeover switch SW is connected to this CPU 12, and this changeover switch
For example, when the switch SW is turned on, it enters the operational data setting mode in which operational data can be set in the predetermined area in the memory mentioned above, and when the changeover switch SW is turned off, it enters the normal operation mode, which is the call processing mode. becomes. Here, operational data includes things such as ``Which key telephone should ring the bell when a call is received from a certain central office line?'' or ``Which central telephone can be used by a certain central telephone? Refers to data necessary for the operation of electronic key telephone equipment, such as "Which central office lines cannot be used?"

Such operational data is stored in the operational data setting mode when _a specific EKT (for example, _{EKT 2 2} ) is input and set. And EKT2 ₁ , 2 ₂ ,..., 2 _o
and the CPU 12 are connected by interface circuits (hereinafter referred to as IFU) 11 ₁ , 11 ₂ , ..., 11 _o , and the data (signals) sent from the EKTs _{2 1} , 2 ₂ , ..., 2 _o are IFU11 ₁ ,11 ₂ ,…,
11 _o to the CPU 12, and conversely, the CPU
The data (signal) sent from 12 is sent to IFU11.
EKT2 ₁ , 2 ₂ ,…, via ₁ , 11 ₂ ,…, 11 _o
It is designed to reach 2 _o .

As mentioned above, in the electronic key telephone device as shown in FIG.
EKT2 ₂ becomes unable to operate as a general EKT, becomes a dedicated terminal for setting operational data, and is set to call processing mode by the changeover switch SW.
All EKTs _{2 1} , 2 ₂ , ..., 2 _o including EKT 2 2 will operate as general EKTs.

[Problems with background technology]

However, in general, the main device 1 is often installed in the shadows or the like so that the user's actions are not obstructed, and the specific EKT 2 ₂ and the main device 1 are often located at a relatively long distance.

Therefore, when setting the operational data, the person setting it first goes to the installation location of the main device 1, turns on the changeover switch SW, and then selects the specific EKT2 ₂
Return to the installation location. Therefore, it is necessary to set the operational data, and after completing the setting, go to the installation location of the main device 1 again and turn the changeover switch SW to the OFF state, which has the disadvantage that the setting work is inefficient.

[Purpose of the invention]

The present invention was made in view of the above-mentioned drawbacks, and its purpose is to place the EKT near the main device and connect it to the main device so that it acts as a specific EKT, at least when setting operational data. An object of the present invention is to provide an electronic button telephone device.

[Summary of the Invention] Therefore, in the present invention, a switch is provided on the specific EKT side lead wire of the IFU connected to the specific EKT, and a connection terminal for connecting a button telephone is provided in the main device, and the above switch is provided. The configuration was such that a specific EKT or connection terminal could be connected or disconnected from the above IFU.

[Embodiments of the invention]

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a block diagram showing an embodiment of the present invention. In the figure, the same components as in Figure 1 include:
The same reference numerals as in FIG. 1 are used, and the explanation thereof will be omitted.

In this example, as is clear from the figure,
A switch SW1 is provided on the lead wire on the specific EKT2 _{2 side of the IFU 11 2 to} which the EKT 2 ₂ is connected. This switch SW1 is a switch that works in conjunction with the changeover switch SW, and when in call processing mode, the IFU11
₂ and EKT2 ₂ are connected. In addition, the main device 1
The EKT (e.g. shown in Figure 2)
EKT other than EKT2 ₁ , 2 ₂ ,..., 2 _o ,
A connection terminal 13 is provided for connecting EKTs (EKTs of the same type as EKTs _{2 1} , _{2 2} , . . . , 2 _o ). This connection terminal 13 is, for example, a terminal block or a plug that is one side part of a connector, and is connected to each other.
It can be coupled with an EKT lead wire or a receptacle holder at the tip of the lead wire. When the changeover switch SW is turned on, the switch SW1 is operated to connect the IFU ₁₁₂ and the connection terminal 13.

Therefore, when setting the operational data, the person setting the operational data must bring an EKT not shown in Figure 2, which is the same type as EKT2 ₁ , 2 ₂ , ..., 2 _o in Figure 2. Then, go to the installation location of main device 1,
For example, first, connect the connection terminal 13 to the EKT you brought with you, and turn on the changeover switch SW. Then, switch SW1 disconnects EKT2 ₂ and connects IFU.
11 Flip to the connection terminal 13 side to connect _{the 2} and the EKT you brought with you. This allows the configurator to configure operational data using the EKT that they bring with them. After setting is complete, when the changeover switch SW is turned off, all EKT2 ₁ , including EKT2 ₂ in Fig. 2,
2 ₂ , ..., 2 _o can be used for normal calls.

FIG. 3 is a block diagram of another embodiment. In the embodiment shown in FIG. 2, a manual switch SW2, which does not operate in conjunction with the changeover switch SW, is provided in place of the switch SW1 in FIG.

Therefore, in this embodiment, EKT2 ₂ is the main device 1.
When the EKT2 is installed near the EKT2, you can set the operational data while keeping the manual switch SW2 tilted toward the EKT2 ₂ side as shown in the diagram. In addition, the main device 1
If the EKT 2 and EKT _{2 2} are far apart, the operator may perform the operations described in FIG. 2 using the EKT he or she brought with him. Furthermore, after the changeover switch SW is turned on and the operation data setting mode is entered, the criteria for determining that the CPU 12 determines that the data is input from a specific EKT is that the IFU 11 ₂ (specific
This information is input from the IFU to which the EKT is connected, and the information specified for each system will be used.

Furthermore, although there may be any number of specific EKTs, one set of connection terminals and switches is sufficient.

〔Effect of the invention〕

As explained above, according to the present invention, specific
Even if the EKT is far away from the main device, another EKT can be placed near the main device and connected to function as a specific EKT, making it easier to set operational data.

In addition, when the switch is a manual type, depending on the distance between the main device and the specific EKT, the switch can be operated appropriately to set operational data from the specific EKT installed in advance or from the EKT that the user brings. In addition, if the EKT connected to the connection terminal is not reset even when the switch is set to call processing mode, it can be conveniently used to check whether the settings have been made correctly. .
