When the data terminal is a terminal that does not conform to the I interface and is a conventional X series or V series interface, as shown in FIG. 3, a terminal that conforms to the I interface recommendation, such as an ISDN digital telephone terminal TE10 (terminal A personal computer TE20 (terminal type 2) is connected via type 1). The connection point between the ISDN digital telephone system terminal TE10 and the personal computer TE20 is standardized as a stipulated point R, and communication by various existing terminals that do not comply with the ISDN interface recommendation is configured to be supported by ISDN.

A terminal adapter TA may be provided as shown in FIG. 4 in place of the ISDN digital telephone terminal TE10.

In the ISDN digital telephone terminal TE10 having the above-mentioned configuration, an additional service of the incoming call system prepared for the ISDN digital telephone terminal TE10, for example, answering machine function, billing information recording, busy transfer, communication transfer, night block, caller number display Various data processing functions built into the ISDN digital telephone terminal TE10 with the basic software that can be realized by various function buttons related to recording and transmission system additional services, such as transmission by speed dial button, transmission by second electric line, and free dial Therefore, there is a problem that the personal computer TE20 having an extremely large amount and high-speed data processing function cannot take in or substitute the various functions of the ISDN digital telephone system terminal TE10 by the personal computer TE20.

[Object of the Invention] The present invention has been made in view of the above-mentioned points. An ISDN in which telephone system control can be performed by the personal computer by substituting various functions related to the function buttons of the ISDN digital telephone system terminal by the personal computer. The purpose is to provide digital terminals.

[Means for Solving the Problems] In order to achieve the above object, the ISDN digital terminal according to the present invention is a prescribed point T of an ISDN user / network interface.
, An ISDN digital telephone system terminal connected to the line termination device, a personal computer connected to the ISDN digital telephone system terminal and capable of performing data communication via the line termination device, and a function button of the ISDN digital telephone system terminal. And the ISDN digital telephone system terminal interface for controlling the calling / receiving function and the voice storing function related to the above from the personal computer.

[Embodiment] A preferred embodiment of the ISDN digital telephone terminal of the present invention will be described in detail below with reference to FIGS. 1 and 2.

In FIG. 1, 1 is a bus cable. The bus cable 1 consists of four signal transmission lines, and the line termination device DSU
At the specified point T. Line terminator DSU to I
SDN digital telephone terminal TE1N (N is 1,2 ... 8) is defined as a maximum of eight access leads by the power feeding method, so modular socket MSn and plug MPn
(N is 1 to 8) is composed of 8 pins.

The personal computer TE2N (N is 1, 2 ... 8) is I
A terminal type 2 data terminal that does not conform to the interface is used to access the ISDN digital telephone terminal TE11 ... at the specified point R. ISDN digital telephone terminal TE11 …… has 25 pins
Personal computer with RS-232C connector
It can be connected with the data terminal connection jack provided on the connection cord of TE21 …….

The ISDN digital telephone terminal TE11 ... has been set at the specified point T
An ISDN interface 2 and a control circuit 3 are provided. The control circuit 3 is provided with a personal computer-to-ISDN digital telephone interface 4 (hereinafter referred to as a data-to-telephone interface).

The data-to-telephone interface is the ISDN digital telephone terminal TE11 ..... The dialing deletion of the speed dial by the additional button of the additional service provided on the ISDN digital telephone terminal. Notifications, etc., display of phonebook by page buttons such as electronic phonebook, display of billing data of additional services of incoming system, storage, answering machine mode setting for answering machine function, recording of message, call transfer, call transfer, nighttime In addition to sending and receiving messages during blockage, personal computer TE21 …… can store and process communication data.

Sending and receiving such information is done by ISDN digital telephone terminal TE11 ....
The control changeover switch 4a provided for the personal computer TE21 or the detection circuit 4b for detecting the escape sequence of the personal computer TE21 switches the control by the mode changeover circuit 5 to the data mode / telephone mode.

[Operation of the Invention] In the ISDN digital system terminal having the above configuration, the control selector switch 4a is operated and the mode selector circuit 5 is in the data system mode. ) Billing display, various telephone connections, and call data are stored in the memory of the personal computer TE11 .... Also, the incoming / outgoing call, connection, and call data to / from the ISDN telephone terminal 11 …… are not sent from the personal computer TE11 ……, and the ISDN digital telephone terminal TE11 …… can be placed under the control of the personal computer TE21 ……. . It should be noted that when the mode switching circuit 5 is in the telephone system mode, only transmission / reception control of the data system is performed.

[Advantages of the Invention] An ISDN digital telephone system terminal according to the present invention is connected to an ISDN digital telephone system terminal connected to a line terminating device at a prescribed point T of an ISDN usage network interface, and to the ISDN digital telephone system terminal. A personal computer capable of data communication through the line terminating device, and a personal computer-to-ISDN digital telephone system for controlling from the personal computer the outgoing / incoming function and the voice storage function related to the function buttons of the ISDN digital telephone system terminal. Since it is composed of a terminal interface, there is an effect that a data terminal such as a personal computer which does not conform to the I interface can control various functions for the ISDN digital telephone system terminal.
