Abstract

PURPOSE:To improve the operability by using remote control from a key telephone set terminal equipment so as to reference and revise setting information of a key telephone master set at a remote location. CONSTITUTION:In the case of referencing and revising setting information of a key telephone master set 1, the key information informed to a control means 10 is converted into an analog signal by a MODEM means 9 and the signal reaches a trunk line circuit 2 of the set 1 via a trunk line circuit 8 and a public line 6 and the signal is informed to the control means 4 as a digital signal by the MODEM means 3. The control means 4 uses the key information to reference and revise the setting information of the storage means 5. Thus, a key telephone set 13 of a key telephone master set 7 is used to reference and revise the setting information of the set 1 at a remote location as if the setting information of the key telephone master set 7 accommodated therein were referenced and revised with the same operation. Thus, the operability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a key telephone device that allows setting information of the key telephone device to be referenced and changed remotely using a public telephone line or the like.

(Prior Art) FIG. 2 shows a configuration for referring to and changing setting information of a conventional key telephone device by remote control. In FIG. 2, 31 is a key telephone main device, and its internal configuration includes a central office line circuit 32 for connecting to a public line;
It has modulation/demodulation means 33 for converting between analog and digital signals, control means 34 for processing input/output information, storage means 35, and an extension circuit 36 for accommodating a telephone terminal in the extension. 37 is a button telephone terminal capable of displaying letters and numbers, 38 is a public line, 39 is a modem, and 40 is a data terminal such as a personal computer equipped with a CRT and a keyboard.

Next, the operation of the above conventional example will be explained. In FIG. 2, when referring to or changing the setting information of the button telephone device stored in the storage means 35, the control means 3
4 inputs and outputs information. Therefore, when referring to or changing the setting information, it is usual to manually press the keys while looking at the display on the key telephone terminal 37. When referring to or changing the setting information of the conventional example described above by remote control, the button telephone main device 131 connects to the public line 38 via the central office line circuit 32.
Since the setting information stored in the storage means 35 is connected to the data terminal 40 via the modem 39 through the control means 34, the setting information is converted into an analog signal from the control means 34 through the modem 33, and is then sent to the modem 39 via the central office line circuit 32. Then, it becomes a digital signal again and is displayed on the data terminal 40.

Further, the key information input from the data terminal 40 is transmitted to the control means 34 through a completely reverse route and becomes data for operating the setting information in the storage means 35.

Therefore, even in the conventional example, the data terminal 40 can refer to and change setting information in the key telephone main device 31 at a remote location through the public line 38 using the CRT and keyboard.

(Problem to be Solved by the Invention) However, in the conventional button telephone device described above, the display and operation from the button telephone terminal and the display and operation from the data terminal are not necessarily the same, so two types of operations are required. There was a problem that it had to be done.

The present invention solves these conventional problems,
An object of the present invention is to provide a button telephone device that allows setting information of a button telephone main device to be referenced and changed from a remote button telephone terminal using exactly the same operation as an extension button telephone terminal of the key telephone main device. It is something.

(Means for Solving the Problems) In order to achieve the above object, the present invention connects a button telephone terminal capable of displaying characters and numbers to the extension circuit of a key telephone main device, and further connects the key telephone main device to a public telephone. By connecting to the key telephone main device at a remote location via a line,
It is possible to refer to and change setting information of a key telephone main device at a remote location by remote control from a key telephone terminal.

(Function) Therefore, according to the present invention, there is provided a method for referring to and changing setting information in a key telephone main device located at a remote location from a key telephone terminal, and a method for referring to and changing setting information in a key telephone main device in which the key telephone terminal is housed. can be referenced and changed in exactly the same way.

(Embodiment) FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a key telephone main unit located at a remote location, which has a central office line circuit 2, modem means 3, control means 4, and storage means 5. 6 is a public line, 7 is a button A main device accommodating a button telephone terminal 13, and a central office line circuit 8.
It has a modulation/demodulation means 9, a control means 10, an extension circuit 11, and a storage means 12.

13 is a button telephone terminal with numbers and characters on the front.

Next, the operation of the above embodiment will be explained. In the above embodiment, it is assumed that the office line circuit 2 of the key telephone main device 1 and the office line circuit 8 of the key telephone main device 7 are connected via the public line 6. When referring to or changing the setting information of the button telephone main device 7 itself using the button telephone terminal 13, the key information of the button telephone terminal 13 is notified to the control means 10 via the extension circuit 11, and the control means 10 Processing necessary for referencing and changing the setting information in the storage means 12 is performed, and display information is displayed on the button telephone terminal 13. On the other hand, when referring to or changing the setting information of the key telephone main device 1, the key information notified to the control means 10 is converted into an analog signal by the modulation/demodulation means 9 and sent to the key telephone main device via the public line 6 through the single station line circuit 8. The signal reaches the station line circuit 2 of the device 11, and is notified to the control means 4 as a digital signal by the modulation/demodulation means 3. The control means 4 refers to and changes the setting information in the storage means 5 using the key information. If necessary, pushbutton telephone terminal 1
The control means 4 of the button telephone main device 1 transmits the same display information as the information displayed on the display unit 3 to the modulation/demodulation means 39 and the central office line circuit 2.3. Public line 6. Office line circuit 8 of key telephone main unit 7. The control means lO is notified via the modulation/demodulation means 9, and the control means 10
can display the display information on the key telephone terminal 13 via the extension circuit II. As described above, according to the above embodiment, the key telephone terminal 13 of the key telephone main device 7
You can refer to and change the setting information of the key telephone main device 1 in a remote location using the same operation as referring to and changing the setting information of the key telephone main device 7 where the key telephone main device 7 is located.
Can be changed.

(Effects of the Invention) As is clear from the above embodiments, the present invention is capable of self-accommodating operations for referring to and changing the setting information of a remote key telephone main device using a key telephone terminal that can display a single character or number. This method has the advantage of being able to refer to and change the setting information of the key telephone main device in exactly the same way as the conventional key telephone main device, and has the effect of improving operability.
