Abstract

PURPOSE:To set an attribute information such as a type of a data terminal unit connected to an exchanger simply by an user by providing a connecting device between each of plural data terminal units and each line circuit connecting these units to a switch network and setting an attribute information of the data unit terminal in each of the connecting devices. CONSTITUTION:The present exchanger comprises a swtich network 1, a central control device 2, a main memory device 3, a line circuit 4 and the others and a data terminal unit 6 is connected to the line circuit 4 through each connecting device 5. By an operation of a switch 56, a subscriber using the data terminal unit sets an attribute information of the terminal unit. In a process of an ex changing processing, the central control device 2 can read a previoutly set terminal attribute information by a switch 56 through a terminal control device 57 in Fig. 2 from the connecting device 5 via the line circuit 4. In this manner, the obtained attribute information is used for a judgement of a connecting control and a connection is done to a partner data terminal unit different in attribute and a computer.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic exchange that accommodates a plurality of data terminal devices and is capable of performing exchange processing between the terminal devices, and in particular, relates to an electronic exchange that accommodates a plurality of data terminal devices and is capable of performing exchange processing between the terminal devices. This is related to the setting method.

2. Description of the Related Art Conventionally, all so-called station data including attribute information of data terminal equipment accommodated in this type of electronic exchange is stored centrally in the main memory of the main body of the electronic exchange. A common method was to change the information on the terminal that accommodates the station data from the processing device.

That is, in the conventional system, the terminal connection device 5 is deleted from the configuration shown in FIG.
The station data is centrally managed within the station, and changes to the station data do not have to be made through the maintenance processing device 7.

In conventional exchanges mainly for voice exchange, terminal attributes are generally constant and do not need to be changed frequently, so there is no particular inconvenience.

(For example, "Electronic Communication Handbook," Institute of Electronics and Communication Engineers, March 30, 1982, Ohmsha, pp. 888-891.
) However, in recent complex exchanges that have data exchange functions and voice exchange functions, data speed, protocol (procedure), JIS-A
The possibility of accommodating data terminal devices having a variety of different terminal attributes such as standard codes such as SCII has increased, and moreover, it has become possible for the user to freely change the terminal device.

Therefore, there is a drawback that the attributes must be changed from the maintenance processing device each time.

Problems to be Solved by the Invention The purpose of the present invention is to solve the above-mentioned drawbacks, namely Take 1.
An object of the present invention is to provide a method for setting attribute information of a data terminal device, which solves the problem that the station data of the attribute information of the terminal device must be changed one by one from a maintenance processing device.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention consists of a switch network, a central control unit, a main memory, and terminal interface circuits such as line circuits and trunk circuits. In an electronic exchange, a connecting device is provided between each of the plurality of data terminal devices and each line circuit that connects them to the switch network, and attribute 1'* information of the data terminal device is set in each of the connecting devices. A configuration in which means are provided is adopted.

Operation Since the setting method of the present invention is configured as described above, attribute information is transferred between the central control unit and the connection device in the process of exchanging data terminals, and data terminals with different terminal attributes are transferred. It is possible to perform an exchange function between machines, and since each connecting device is connected between each terminal and the line circuit, the attribute information can be set and changed from each terminal.

Example Next, embodiments of the present invention will be described with reference to the drawings.

Referring to FIG. 1, which shows a relay system diagram of an electronic exchange to which the data terminal device attribute information setting method according to an embodiment of the present invention is applied, this exchange includes a switch network l, a central control unit 2, and a main storage device. 3, a line circuit 4, and the like, and the data terminal device 6 is connected to the line circuit 4 via each connection device 5.

FIG. 2 shows details of this connection device 5, in which an input gate circuit 5 is connected to a communication path 51 via a buffer circuit 52.
3. Output gate circuit 54. Address expansion circuit 55. Switch 56 and terminal control device 57 for setting attributes
is connected.

Next, the operation of this method will be explained. First, by operating the switch 56, a subscriber using a data terminal device sets attribute information of the terminal device. In the process of exchange processing, the central control unit 2 reads the terminal attribute information previously set by the switch 56 from the connection device 5 via the line circuit 4 and the terminal control unit fIt57 shown in FIG. Can be done.

The attribute information obtained in this way is used to determine connection restrictions, and a connection is established with a partner data terminal device or computer having a different attribute.

Furthermore, this attribute information is transferred upon request from the converter, the partner terminal, and the maintenance device.

In the example shown in FIG. 2, a switch 56 is used as a means for setting attribute information, but in the other example shown in FIG. It is also possible to provide a communication means between the connecting device 5 and the attribute information of each data terminal device to be directly stored in the memory within the connecting device 5. Further, in this case, the connecting device 5 can also be configured integrally with the line circuit 4.

Effects of the Invention As explained above, according to the present invention, by providing a connection device for setting attribute information of a data terminal, a user can easily set attribute information such as the type of a data terminal connected to an exchange. This has the effect of eliminating the need to change station data from the maintenance device.
