Abstract

PURPOSE:To improve the efficiency of installation operation and to shorten the operation time by integrating interfaces and connecting an analog equipment and a data equipment to three composite interfaces without altering hardware. CONSTITUTION:An independent telephone set 5 is connected to the main device 4 of a key telephone system by connecting a telephone line 8 to the analog interface(IF) means 2a of a composite IF 1a so as to send and receive only an analog signal and a dial signal to and from the main device 4 through the telephone line 8, and the telephone set 6 is not connected to the digital IF means 3a. Further, a key telephone set 6 has a telephone line 9 for transmitting an analog signal and a data line 10 for transmitting a digital signal, so it is connected to the analog IF means 2b and digital IF means 3b of a composite IF 1b. Further, a data terminal 7 has only a data line 11 for sending and receiving a digital signal, so it can be connected to the device 4 by connecting the line 11 to the digital IF means 3C of a composite IF 1C and not connected to the analog IF means 2C.

Regarding

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 2, an interface installed in a main unit 4 of this type for connecting a single telephone 5, a key telephone 6, a data terminal 7, etc., is shown in FIG.
a, 5b to 5n and a key telephone 6 which is a non-single telephone
Since a and 6b to 6n are different in the form and specifications of each communication signal, the individual telephone interfaces 13a and 13b to 13n and the button telephone interfaces 14a and 14b to 14n corresponding to them are provided and connected separately. . In the figure, 8a and 8b to 8n are call lines of the individual telephones 5a and 5b to 5n, and 9a, 9b to 9n and 1
0a, 10b-10n are key telephones 6a, 6b-6
n communication lines and data lines. Further, 15 is a single telephone interface unit that houses a plurality of single telephone interfaces 13a and 13b to 13n, and 16 is a plurality of button telephone interfaces 14a and 14b to 1.
A button telephone interface unit 4n containing 4n is a main device. Therefore, in such a configuration, when the terminal device to be connected is changed, the corresponding interface is replaced accordingly or, as shown in FIG. 3, the key telephone interface 14a.
In the case of connecting the single telephone 5a to the above, a means has been used in which a separate single interface 17 for mutual conversion is provided between them to connect them.

[0003]

However, it is necessary to change the interface each time the terminal device connected to the main device 4 is changed, or to change the hardware such as adding a separate interface. However, it was complicated and time-consuming, and there was a risk of setting mistakes. Also, as described above, the individual telephone interfaces 13a, 13b to 13n and the button telephone interfaces 14a, 14b to 14 are used.
Normally, a plurality of n are respectively stored in the single telephone interface unit 15 and the button telephone interface unit 16, and at the time of changing, even if only one terminal device is changed, this must be changed for each interface unit. Therefore, even unnecessary interface units have to be replaced, which is uneconomical because of a heavy burden on installers and users.

The present invention has been made in view of the above problems, and an object thereof is to provide an analog device such as a single telephone 5 or an analog / data composite device such as a key telephone 6 and a data device such as a data terminal 7. It is to provide a composite interface that can be connected without changing the hardware.

[0005]

In order to solve the above-mentioned problems, the present invention provides an analog interface means 2 to which analog equipment is connected in a composite interface 1a, 1b, 1c installed in a main unit 4 of a button telephone device.
a, 2b, 2c and the digital interface means 3a, 3b, 3c to which the data equipment is connected are housed in the same interface, and the hardware can be changed for any of the analog equipment, the analog / data composite equipment, and the data equipment. The configuration is such that connection is possible without the need.

[0006]

[Function] Analog interface means 2a, 2b, 2
c serves as an interface to an analog device such as an analog signal section of the single telephone 5 or the analog type button telephone 6, and the digital interface means 3a, 3b, 3c is a data terminal or a digital control section of the analog type telephone 6 or the like. The data terminal 7 is, for example, a DSS terminal (direct, station, selection), which has a console provided with switches corresponding to extension terminal devices, It has a function of automatically holding an extension call directly by pressing a switch of a corresponding terminal, and is used for reception.

However, if the analog interface means 2a, 2b, 2c and the digital interface means 3a, 3b, 3c are accommodated in one interface to form a composite interface, an interface capable of supporting both analog and digital signal systems. Next to
It can be used for any of analog devices, data devices, and analog / data composite devices.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing the basic configuration of the present invention.
In the figure, reference numerals 1a, 1b and 1c are composite interfaces, 2a, 2b and 2c are analog interface means which serve as an interface for analog signals from a terminal device, and 3a, 3b and 3c are interfaces which carry digital signals from the terminal device. The digital interface means 4 which plays the role of 4 is a main unit of a button telephone device, but may be a private branch exchange, 5 is a single telephone, 6 is a key telephone, and 7 is a data terminal.

Therefore, since the single telephone 5 sends and receives only analog call signals and dial signals to and from the main unit 4 through the communication line 8, the call line 8 is connected to the analog interface means 2a of the composite interface 1a. Therefore, the main device 4 is connected, and in this case, the digital interface means 3a is not connected. Further, since the key telephone 5 has the call line 9 for transmitting an analog signal and the data line 10 for transmitting a digital signal, the key telephone 5 has the analog interface means 2b and the digital interface means 3b of the composite interface 1b, respectively.
Connect to. Further, since the data terminal 7 has only the data line 11 for transmitting and receiving digital signals, it can be connected to the main device 4 by connecting the data line 11 to the digital interface means 3c of the composite interface 1c. In this case, the analog interface is used. The means 2c are not connected.

As described above, by using the composite interfaces 1a, 1b, and 1c according to the present invention, it can be used for any of analog devices such as the single telephone 5, analog data complex devices such as the key telephone 6, and data devices such as the data terminal 7. Even if the terminal device is changed, the installer only needs to perform the necessary wiring, and it is also possible to connect different types of terminal devices to the respective composite interfaces 1a, 1b, 1c. .

Further, each composite interface 1a, 1
Although each of the terminals b and 1c is connected to each terminal device by a connector (not shown), it is possible to easily attach the connector to the composite interfaces 1a, 1b and 1c by using a standardized connector. It is like this.

[0012]

As described above, according to the present invention, the interfaces conventionally prepared separately are unified, and the composite interfaces 1a, 1b, 1c of the same type are provided with analog devices such as the single telephone 5 and the key telephone 6. Since it is possible to connect analog / data composite devices such as the above, and data devices such as the data terminal 7 without changing the hardware, the work efficiency of the installation work is improved, and the work time is shortened, thus reducing the cost. In addition, there is no fear of installation error, there is no waste of exchanging unnecessary interfaces, the flexibility of the system configuration is increased, and the burden of design is reduced.
