Abstract

PURPOSE:To lighten the burden of a central control unit, and to reduce manhour for the change or the addition of a host computer by detecting a processing request from a multifunctional terminal equipment by a subscriber's circuit, and generating and editing a processing request destination address, and sending processing data to the central control unit and all the subscriber's circuits. CONSTITUTION:The subscriber's circuit 130 having detected the state change of the multifunctional terminal equipment 140 identifies the processing request destination, and generates the request destination address, and further, sends data added with the processing data to the central control unit 100 and all the subscriber's circuits 130. Accordingly, the central control unit 100 or the subscriber's circuit 130 of a receiving side can decide to adopt or reject the received processing data by only confirming the processing request destination address. Thus, not only the burden of the central control unit is lightened, but even when the host computers 150, 160 are changed or added, work to deal with it can be curtailed to only the change of the contents of the storage device of the subscriber's circuit 130, and the deterioration of service during it is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic switching system, and more particularly to a data transmission/reception system between a multi-function terminal device and a host computer.

[Prior Art] Conventionally, data transfer regarding a processing request from this type of multi-function terminal device to a host computer has been performed as follows. That is, a subscriber circuit that detects a change in the status of a terminal device transfers data to the central controller to request processing based on the change in status. The central control unit analyzes the received data, and if it is a processing request for a host computer, it processes and re-edits the data into a format that the host computer can interpret, and then transfers the data to the relevant host computer.

[Problems to be Solved by the Invention] In the conventional data transmission/reception system described above, the contents of processing requests and processing data from a multi-function device are not in a format that can be directly interpreted by a host computer. Therefore, processing requests from the multi-function terminal device to the host computer are
As with other call processing services, central controller intervention is required. The Zunawara central control unit analyzes processing requests from multi-function terminal devices, identifies the request destination, and hosts the processed data by referring to the corresponding data in the main memory connected to the central control unit. 1. It was necessary to convert the data into a format that can be interpreted by a computer and then transfer it.

Therefore, when a host computer is changed or added, it is necessary to change or add the contents of the main memory corresponding to the change or addition, which requires a lot of man-hours, and the data conversion process This has the drawback of increasing the load on the control device.

SUMMARY OF THE INVENTION An object of the present invention is to provide a terminal-postcomputer data transmission/reception system that solves the above-mentioned problems.

[Means for Solving the Problems] The present invention provides an automatic switching system in which a multi-function terminal device is connected to a main switch via a subscriber circuit, and a host computer is connected to a main switch via a subscriber circuit. means for detecting a processing request from a multi-function terminal device to which the circuit is connected; means for the subscriber circuit to create/edit a processing request destination address corresponding to the processing request; means for adding processing data to the request destination address; means for transmitting the processing data including the created processing request destination address to a central control unit and all accommodated subscriber circuits; and means for receiving the transmission data. The central control unit or the subscriber circuit that receives the received data has means for determining whether to adopt or discard the received processed data based on the processing request destination address of the received data, and means for transmitting the processed data to the corresponding host computer. This is a data transmission/reception method between a terminal and a postcomputer.

[Example] Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. In FIG. 1, a central control device 100 is a main storage device 110.
with a main switch 120. Control the subscriber circuit 130 f
lfl. The subscriber circuit 130 is composed of a control section 131, a storage section 132, and a data transmission/reception section 133, and monitors the status and controls the operation of connected terminal devices such as the multifunction terminal device 140. Host computer 150. The host computer 160 is connected to this automatic exchange system via the subscriber circuit 130 and can be operated from the multifunction terminal device 140.

FIG. 2 is a conceptual diagram of a processing request destination address creation table stored in the storage unit 132 in the subscriber circuit 130.

FIG. 3 is a conceptual diagram showing the structure of data transmitted to the central control unit 100 and all subscriber circuits when the subscriber circuit 130 detects a change in the state of a connected terminal device, and FIG. It is a figure which shows the specific example. Hereinafter, a case in which the host computer 160 is to be operated from the multi-function terminal device 140 will be described using FIGS. 1 to 4.

When a dedicated button for requesting access to the computer 160 installed on the multi-function terminal device 140 is pressed, the control section 131 in the subscriber circuit 130 detects this via the data transmission/reception section 133. Then, the process request destination address generation table (FIG. 2) stored in the storage unit 132 is indexed according to the content of the detected state change, and the process request destination at the time of pressing the button is searched.

As a result, if it is determined that the request destination is the host computer 160, the address corresponding to the host computer 160 is set as the request destination address and the first information of the transmission data. Roughly, the content of the processing request (temporarily processing △) is used as second information, and if there is any other input from the multi-function terminal device 140, it is used as additional data and third information to create transmission data ( Figure 4). Then, the control unit 131
controls the data transmitting/receiving section 133 and sends this transmission data to the central control unit 100 and all subscriber circuits.

The central control unit 100 or subscriber circuit 130 on the receiving side checks the first information of the received data, that is, the request destination address, and determines that the data is addressed to itself, or more precisely, the device corresponding to the request destination address is the terminal device. If the received data is accommodated, the received data is adopted, and if not, it is discarded. In this example, only the subscriber circuit 130 housing the host computer 160 employs this received data, and furthermore, the controller within the subscriber circuit 130 controls the data transmitter/receiver.
The received data is transferred to the host computer 160,
Other subscriber circuits 130 and central controller 100 discard the received data.

[Effects of the Invention] As explained above, in the present invention, a subscriber circuit that detects a change in the status of a multi-function terminal device identifies a processing request destination, creates a request destination address, and sends data to which processing data has been roughly added. By sending the data to the central control unit and all subscriber circuits, the receiving central control unit or subscriber circuit can decide whether to accept or discard the received processing data simply by checking the processing request destination address. This eliminates the need for the central control unit to convert the format of transferred data and secure the main switch control line using known methods, which not only reduces the burden on the central control unit, but also reduces the burden on the host computer. Even if there is a change or addition to the address, the work to deal with it can be reduced to just changing the contents of the storage device in the subscriber circuit, which the subscriber circuit refers to in order to create a processing request destination address. This has the effect of preventing deterioration of call processing services during that time.
