Abstract

PURPOSE:To eliminate expensive interface for automatic transmission and simplify and economize the system by unifying interface for automatic transmission and succeeding data communication. CONSTITUTION:Selection number of an object of communication is inputted from the inputting section 26 of a terminal device 23 and accumulated in a memory 27, and at the same time, call display is transferred from a signal interface section 24 to the signal inputting and outputting section 21 of a network controlling device 15 through a signal interface line 22. Thereafter, when exchange of call display and dial tone detection signal and exchange of selecton number with subscriber's circuit are completed by a controlling section 19, the controlling section 19 gives reply monitor command to a circuit controlling section 16. Then, it commands sending out of carrier to an MODEM section 17, and makes exchange of reply and carrier. Data sends a signal from the terminal unit 23 to the MODEM section in a signal selecting section 20 and makes exchange by one interface.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to automatic transmission control system 1. More specifically, the terminal device and the network control device are connected through one signal interface unit, and the signal corresponding to the selected number sent from the terminal device and the communication data are transmitted through the one signal interface unit. The present invention relates to an automatic call control method for transmitting and receiving data via a communication network.

Prior Art and Problems An example of the configuration of a conventional system of this type is shown in FIG. In the figure, 1 is a telephone subscriber line, 2 is a network control device, 3 is a line control unit, 4 is a dial control unit, 5°7 is a communication signal line, and 6
1 is a modem, 8 is a dialing signal line, 9 is a terminal device, 10 is a communication interface section, 11 is an automatic calling interface section, 12 is a control section, and 13 is an output section.

A signal for automatic transmission between the conventional terminal device 9 (for example, a personal computer) and the network control device 2 is inputted from the input/output section 15 and sent to the interface 11 for automatic transmission by the control section 12.
The data is transferred to the dial control unit 4 via the dial signal line 8, and then transferred to the line control unit 3 via the modem 6 for data communication.
The method was to transfer the information to

FIG. 2 is a diagram showing a signal sequence from the automatic transmission to the start of communication in the conventional system shown in the $1 diagram.

In FIG. 2, when a call is displayed on the input/output unit 15 of the terminal device 9 (for example, a personal computer), this call display information is transmitted to the control unit 12. The signal reaches the automatic calling interface section 11 and the dial control section 4, and based on this, the dial control section 4 controls the single line control section 6 to make a call to the subscriber line 1 (putting it in an on-hook state). As a result, when the line control section 3 receives the dial tone (call ready signal) DT from the subscriber line 1, it is input to the input/output section 13 and sent to the dial control section 4 via the control section 12 and the automatic dialing interface 11.
The phone number of the other party transferred to (for example, A, B, C).

D) is converted into a dial signal in the dial control section 4 and sent to the subscriber line 1 via the line control section 6.

When the other party responds, the response signal is received by the line control section 3, passes through the dial control section 4, and then reaches the input/output section 13 via the automatic calling interface 11 and the control section 12, where the other party's response is displayed.

After responding, the other party's terminal starts transmitting the carrier, and when the modem 6 receives the carrier, it also starts transmitting the carrier. Subsequent communication will be performed via the modem 6, and if transmission data is input from the input/output unit 13, this communication data will reach the modem 6 via the control unit 12 and the communication interface 10, and will be sent to the modem 6. The carrier is modulated and the transmission data is sent.

Received data is also transferred and received in the opposite direction to the above. In the conventional system, as mentioned above, two different interfaces (10, 11) are used for automatic transmission signals and data communication signals.
had to be prepared.

Furthermore, as shown in FIG. 2, in the sequence from automatic transmission to communication, the above two interfaces are not used simultaneously, resulting in a redundant configuration.

As a communication interface in FIG.

Widely used EXA standard R8-232C (JI
If a communication interface unit 10 corresponding to this interface is adopted (equivalent to SC-6361), the communication interface section 10 corresponding to this interface can be obtained at low cost as a general-purpose part. circuit is not available, so the automatic transmission interface (11
) circuits are expensive. Therefore, the conventional system which required two interfaces, one for communication and one for automatic transmission, had the disadvantage of being expensive.

Purpose of the Invention In order to solve the above-mentioned drawbacks of the conventional system, the present invention controls automatic calling and data communication using the same general-purpose inexpensive interface, eliminates the expensive automatic calling interface, and improves the performance of this type of system. The purpose is to achieve economicization.

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

FIG. 4 shows the terminal device 23 and network control device 1 of the embodiment shown in FIG.
5 is a diagram illustrating a sequence of signal operations between FIG.

Next, the operation will be explained with reference to FIGS. 6 and 4.

To operate this, first, the input section 26 of the terminal device 26
Selected digits that are the number of the communication partner (for example, A, B, C)
, D) is inputted, the selected number is temporarily stored in the memory g27 via the terminal device control section 25, and is also sent from the signal interface section 24 to the signal input/output section 21 of the network control device 15 via the signal interface line 22. Transfer call indication. At this time, the signal selection circuit section 20 of the network control device 15 is in an initial state, and is in a state where it does not transfer the signal to the modem section 17 but transfers it to the control section 19. The signal input/output section 21 receives the transmission indication, and sends this transmission indication to the control section 19 via the signal selection circuit 20.

When the control unit 19 receives the call display, the control unit 19 controls the line control unit 1.
6 and makes a call to subscriber line 14 (off-hook state)
do. When a dial tone is received from the subscriber line 14 (making a call possible), a dial tone detection signal is sent to the control unit 1.
9 (2) is sent, and the control section 19 converts this into a selected digit sending request and sends it to the terminal device control g 25 via the signal interface section 24.

The terminal device control section 25 successively outputs the selection numbers (A, B, C, D) already stored in the storage section 27 and passes them through the signal interface section 24, signal input/output section 21, and signal selection circuit section 20. It is sent to the control section 19.

The control unit 19 breaks down the received selected number information into individual numbers, and first sends the first number (A) to the dial control unit 18, which converts it into a dial signal corresponding to the number A.
The selection signal is sent to the line 1 via the line control section 16. When the transmission is completed, the line control section 16 sends a transmission completion message back to the control section 19 via the dial control section 18.

When the control unit 19 receives this transmission completion, it transmits a dial signal for the second digit in the same manner as described above.

By repeating this, when all selected numbers have been sent, the control section 19 receives a response monitoring response from the line control section 16 and sends it to the control section 19.

The control section 19 transfers the other party's response zero to the terminal device 25, switches the signal selection section 20, connects the signal input/output section 21 and the modem section 17, and instructs the modem section 17 to send out a carrier. It is also possible to monitor the state of the line by monitoring the modem unit 17 with a small speaker.

After the other party responds, when a carrier is sent from the other party via the subscriber line 14, this carrier is received by the modem section 17, and the carrier reception is sent to the signal selection circuit section 20. Signal input/output section 2
1. Terminal device control unit 2 via signal interface unit 24
5, the terminal device control section 25 converts it into a data input enable signal, and outputs and displays it on the output section 28.

Upon receiving the other party's response and the carrier, the terminal device control unit 25
It receives data input from the input section 26 and sends it to the network control device 15 from the signal interface section 24, and also from the subscriber line 14 to the network control device 15.

Data sent via the interface line 22 is output to the output section 28.

In this way, the signal selection section 20 determines whether or not to send the signal from the terminal device 23 to the modem section 17, so that automatic dialing and data communication, which conventionally were performed separately using two interfaces, can now be performed using one interface. Can be done.

As described in detail of the invention, according to the present invention, the interface of the clothing device, which conventionally controlled two different interfaces to perform automatic transmission and data communication, is unified to perform automatic transmission and data communication. It is possible to use the same interface, and there is an advantage that automatic calling can be made even from a terminal device that only has a data communication interface. Furthermore, control of the terminal device is simplified since there is only one interface, and there is an advantage that an expensive automatic caller interface is not required, making it more economical.

Furthermore, according to the present invention, when the terminal device is a commercially available personal computer, an interface circuit that performs the interface specified in R8-2620 is often equipped as standard, and conventionally this was only used for data communication. However, it is now possible to automatically make calls and communicate from a personal computer without modifying the computer.
