Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a button telephone device that allows the telephone itself to know to which number terminal in the main device the telephone is connected.

Conventional Structures and Problems Generally, in button telephone devices, the following two methods are widely used to assign terminal numbers in the main device to which each telephone is connected and numbers to each telephone.

(1) The number of each telephone shall be a fixed number, determined by a certain relationship with the terminal number of the main device. For example, terminal number 1 is telephone number 10. Terminal number 2 is determined like telephone number 11, etc.

(2) A method in which the number of each telephone can be arbitrarily set using a switch or a program, and does not necessarily have to match the terminal number of the main device.

By the way, when checking the operation of a key telephone device when installing it, performing maintenance inspections, changing the telephone number, etc., it is necessary to know whether the corresponding telephone is connected to the terminal of the main device. .

For this reason, in the past, in cases like this, a number table was created that specified the number of each telephone and the terminal number to which the telephone was connected, and the terminal number to which the telephone was connected was prepared for each telephone. I am writing the following information.

However, in this case, if you have lost the number list or replaced the telephone, the above +11. +21 method In a place where a power supply machine is installed, it is completely impossible to know which terminal the telephone is connected to, so I checked the wiring one by one and changed the program settings on the main device. It was very difficult to find out the terminal number because I had to look it up. In particular, if the telephone and the main device are installed far apart, it is necessary to go back and forth between the telephone and the main device to know the terminal number.
It had the disadvantage of requiring a lot of effort and time.

OBJECT OF THE INVENTION The present invention eliminates the above-mentioned drawbacks of the conventional technology.It is an object of the present invention to eliminate the above-mentioned drawbacks of the conventional technology. The purpose of this invention is to provide an excellent key telephone device that can be easily recognized by the person on the other side.

Structure of the Invention In order to achieve the above-mentioned object, the present invention provides a control circuit of a main device with a memory for storing terminal numbers connected to each telephone, and a predetermined specific operation on the telephone side. A circuit is provided that detects this and sends the terminal number of the terminal to which the telephone is connected, which is stored in the memory, to the telephone, and the telephone receives the terminal number from the main device. It is configured to display numbers, lamps, sounds, etc.

0 is an amplifier and speaker that outputs ringtones, etc., 11 is a data transmission/reception circuit, 12 is a control circuit equipped with a microcomputer and controls inside telephone B, and 13 is a central office line button 2.
In addition to function buttons, dial buttons, etc., the input/output circuit is equipped with various other display functions; 14 is a numeric display for displaying dial numbers, etc.; 15 is a terminal to which telephone B is connected; 6. The four terminals accommodating the four wires of and 7 are the connection terminals of one telephone, and terminal numbers are assigned to them. Similarly to 15, 16 is a four terminal to which another telephone is connected, and 17 is another telephone connected to each of the above four terminals.

Next, the operation of the above embodiment will be explained. Each phone B
, 17, there is no need to assign terminal numbers to them in a standard manner, so they are assigned arbitrarily fixed numbers in advance, such as terminal numbers 1, 2, and 3. . This terminal number and each telephone number connected to it are stored in the memory 4, respectively, and telephone call processing is performed based on the data stored in the memory 4. From main device A to each telephone B.

7, a control signal is sent from the control circuit 3 to the telephone B via both data transmitting/receiving circuits 5 and 11.

7, the control circuit 1
2 receives an incoming call according to the content of the signal.

Controls display, etc. On the other hand, the operation of each function button or dial operation from telephone B is detected by the input/output circuit 13, and this is transmitted from the control circuit 12 through the reverse route (12-1).
1-7-5), the information is transmitted to the control circuit 3 in the main device A, and processing according to the content is performed.

The control circuit 3 of the main device A is programmed in advance so that when a certain key operation (for example, a dial number (special number) not used for normal operation or a certain function button is pressed) is executed on the telephone B. Recognize that this is a terminal number request command.Now, suppose that telephone B wants to know its own terminal number.In this case, perform the above specific key operation on telephone B.Like this. Then, the key operation is transmitted to the control circuit 12 through the input/output circuit 13, and transmitted to the control circuit 3 of the main device A via the transmitting/receiving circuit 11, data line 7, and transmitting/receiving circuit 5.

As mentioned above, the control circuit 3 stores in advance that this is a terminal number request command for telephone B, so the number corresponding to this telephone is retrieved from the memory 4 and sent to the control circuit 12 of telephone B. Transmit. When the control circuit 12 receives this number, it displays the terminal number of the telephone set on the display 14 numerically. This allows the telephone B side to know the terminal number to which its own telephone is connected.

In the above description, a case has been described in which a numeric display element is used as the display 14, but a lamp (a station line lamp or a function lamp) or a speaker may be used for display and sound. That is, when using one lamp, for example, when the control circuit 12 receives number data from the main device A,
The control circuit 12 may be configured to blink a certain lamp by the number of digits in accordance with the number data. Further, in order to make the display easier to understand, the number may be divided into 10th and 1st digits, and an appropriate time may be provided between the digits. For example, if the phone number is 25,
First, it blinks twice at certain intervals. It is also possible to make the light flash again five times at the same cycle as the previous time after a certain appropriate period of time has elapsed. Then, a similar signal may be applied to the speaker 10 to display sound instead of a lamp.

Furthermore, by using a plurality of lamps (for example, using station line lamps, etc.) and combining the lamps, the numbers can be displayed more clearly.

In this way, in this embodiment, by performing a certain predetermined operation on the telephone side, the telephone side can easily know the terminal number to which the telephone is connected. In order to know the number, there is no need to check the settings inside the main device, the wiring, etc. one by one, which is extremely advantageous in practice.

Effects of the Invention As is clear from the above embodiments, the present invention allows the terminal number of the main device to which the telephone is connected to be determined on the telephone by performing a specific predetermined operation on the telephone. It is configured to display automatically, so even if you do not know the connection terminal number of the phone, you can easily find out the terminal number without checking the settings on the main device side. This has the advantage that maintenance inspection and telephone replacement work can be significantly simplified.
