Abstract

PURPOSE:To constitute a data switching system which does not require field confirmation for recognition of the attribute of the destination terminal and systems other than a data system, by transmitting the attribute of a terminal corresponding to a terminal connection interface device to a switchboard to register and hold it at the time of setting this attribute. CONSTITUTION:When the attribute of a terminal 2 connected to a terminal connection interface device 5 is set, it is transmitted to a control signal channel all a transmission line to a switchboard 1. This terminal attribute information is stored in a memory of a common control part 15 and is registered and held in the switchboard 1 which receives the control signal channel. When the attribute of the terminal is set by the terminal connection interface device 6 and a terminal of dial number 300 is called by a terminal of dial number 100 in this state, the common control part 15 in the switchboard 1 reads out attribute information of the terminal of dial number 300 and reports it to the terminal connection interface device 5 of dial number 100. Thus, the terminal of dial number 100 as the calling side is informed of the attribute of the terminal of dial number 300 as the called destination terminal.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a system for exchanging data using an exchange, and particularly relates to a service method provided to a terminal having a terminal interface such as V24. .

(Prior art) In a non-procedural terminal having a terminal interface such as V24, before communicating with the other terminal, it is necessary to know the attributes of the other terminal such as communication speed, parity type, data bit length, stop bit length, etc. , it is necessary to communicate after matching the attributes of itself (the calling party).

Therefore, especially in a data exchange system, each terminal must know the attributes of all of the many terminals with which it wishes to communicate, which increases the burden on the terminals. Furthermore, each time the type of terminal connected to the system changes, the attributes of the other terminal must be newly grasped and managed.

Furthermore, in a data exchange system, the other party's terminal is not necessarily installed in a location adjacent to the own terminal, so it is difficult to check the attributes of the other party's terminal by visiting the installation location or by using a telephone system. There is a need to. However, the former method requires a great deal of effort and also requires confirmation every time the connected terminal is changed, which significantly reduces work efficiency. Furthermore, the latter method requires the installation of a system other than a data system, such as a telephone system, which increases system complexity and system construction cost.

(Problems to be Solved by the Invention) As described above, in conventional data exchange systems, there is no way to easily know the attributes of the other party's terminal, which requires a great deal of effort, complicates the system, and increases cost. There was a problem with bringing it.

The present invention enables the calling terminal to determine the attributes of the calling terminal by providing means for determining the attributes of the calling terminal itself or whether the attributes match those of the calling terminal before communication. The purpose is to provide a data exchange system that does not require on-site confirmation or any other system other than a data system.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a terminal connection interface device between an exchange and a terminal that controls an interface between the two, and a terminal connection interface device that connects to the interface device. a means for setting the attributes of a terminal to be called; a means for transmitting terminal attribute information indicating the attributes of the terminal to the exchange; and a means for transmitting terminal attribute information of the calling terminal transmitted from the exchange to the terminal and setting the attributes thereof. It is characterized by having means for displaying the information, and also having a function of registering and retaining terminal attribute information transmitted from each terminal connection interface device in the exchange.

(Operation) When the attributes of the corresponding terminal are set in the terminal connection interface device, the terminal attribute information is sent to the exchange and registered and held in the memory of the exchange control unit. When the calling terminal makes a call to the other party's terminal for communication,
The terminal attribute information of the other party is read from the memory in the exchange and sent to the calling terminal via the terminal connection interface device to display the attributes, or the other terminal and the calling terminal are Attributes are displayed only if they do not match. As a result, the calling terminal itself can at least ascertain whether the attributes of the calling party terminal match its own attributes, and can decide whether or not communication is possible.

(Embodiment) FIG. 1 is a diagram showing an overview of the entire data exchange system according to an embodiment of the present invention, and FIG. 2 is a diagram showing the internal configuration of the exchange 1 and terminal connection interface device 5 in FIG. 1. It is.

As shown in FIG. 1, this data exchange system has a general configuration consisting of an exchange 1, a terminal 2, a host combination interface 3, and a terminal interface 4, as well as an exchange system 1, a terminal 2, and a host computer 8. It has a configuration in which terminal connection interface devices 5 and 8 are provided. It is assumed that control signals are transmitted between the exchange 1 and the terminal connection interface device 5.8 using a control signal channel independent of the information channel used for data transmission.

Data from the terminal 2 passes through a terminal interface 4 such as a V24 interface provided between the terminal 2 and the terminal connection interface device 5, reaches the line corresponding section 21 in the terminal connection interface device 5, and is connected to the line. Correspondence part 2
1 and the exchange 1 as an information channel. The data of the information channel that has arrived at the exchange 1 is routed to the desired destination terminal by the time switch 13 via the line correspondence section 11 in the line interface 10, and then transferred to the destination terminal by the reverse procedure to the above. reach.

Control signals such as dials and operation keys are notified to the central control unit 22 in the device via the input control unit 24 in the terminal connection interface H5. This control signal is transmitted from the line correspondence section 21 to the exchange 1 through a control signal channel. The contents of the control signal channel received by the exchange 1 are separated into the control highway corresponding section 12 and sent to the control highway 1.
4 to the common control unit 15.

Here, the terminal connection interface device 5 has a function of setting attributes of the terminal 2 connected thereto. Specifically, for example, a special key for setting may be provided on the terminal connection interface device 5, or a special operation may be performed using normal operation keys for dialing, etc., or a switch for attribute setting may be provided. By holding the end □ unconnected interface! Attributes of the terminal 2 connected to the LS device 5 are set.

The terminal attribute information indicating the attributes set in the terminal connection interface device 2 in this way is read by the central control unit 22 in the terminal attribute interface device 2, and sent as a control signal on the transmission path to the exchange 1 via the line handling unit 21. sent to the channel. This terminal attribute information is stored, registered and maintained in the memory in the common control section 15 in the exchange I that received the control signal channel, in the same way as the control signals for dials, operation keys, etc. described above.

FIG. 3 is a configuration example of a conversion table between a physical port and a dial number provided in the memory in the common control unit 15.
FIG. 4 also shows an example of the configuration of a conversion table between dial numbers and terminal attributes.

Now, as an attribute of any terminal, for example, the communication speed is 9.8
00 bps, parity type is even, stop bit length is 1, connect this terminal to boat address rOJ,
Assume that the dial number is set to 300. Setting the dial number is done from a dedicated maintenance terminal. Similarly, as the attributes of another terminal, set the communication speed as 9.800bl)S, the parity type as an odd number, and the stop bit length as 1, connect that terminal to the boat address "20", and set the dial number to 100. Suppose we did.

With the terminal attributes set by the terminal connection interface device 5 in this way, when a call is made from the terminal with dial number 100 to the terminal number 300, the common control unit 15 in the exchange 1 calls the terminal number 300. The attribute information of is read from the conversion table of FIG. 4, sent to the control signal channel of boat address "20", and notified to the terminal connection interface device 5 of number 100.

The terminal connection interface device 5 that has received the terminal attribute information of the other party's terminal reads it in the central control section 21 and converts it into a format for display on the terminal 2 using a program in the control section 21 or the like. Then, this converted terminal attribute information of the other terminal is sent to the information channel of the sending side to the terminal 2.

This makes it possible for the calling terminal number 100 to know the attributes of the calling party terminal number 300.

In this way, you can go to the location where the other party's terminal is installed,
It is possible to display and recognize the attributes of the other party's terminal on the calling terminal without using a telephone system or the like. Therefore, the labor required for communication is reduced, and since it is not necessary to install other systems such as a telephone system, the complexity of the system can be avoided and the cost of constructing the system can be greatly reduced.

Note that the present invention is not limited to the embodiments described above, and can be implemented with various modifications without departing from the gist thereof. For example, in the above embodiment, the attributes of the other terminal are always displayed on the calling terminal, but the attributes of the calling terminal and the attributes of the other terminal are displayed by referring to the conversion table in the exchange l. They may be compared and the attributes of the other party's terminal may be displayed on the calling terminal only when the two do not match. In this way, if both attributes match as a result of the above comparison, that is, if communication is possible,
By not displaying the attributes of the other party's terminal, the terminal operator can determine whether communication is not possible.

Furthermore, if a mismatch is detected as a result of comparing the attributes of the calling terminal and the other terminal, it is possible to not establish a path connection between the terminals, thereby allowing the process to continue without the attribute mismatch. This has the advantage that sending and receiving meaningful information can be prohibited.

Furthermore, in the above-mentioned embodiment, by providing a sending permission flag as shown in FIG. It is also effective to prohibit the sending of information.

[Effects of the Invention] According to the present invention, in a terminal connection interface device that controls the interface between an exchange and a terminal layer, attributes of a terminal connected thereto are set, and the terminal attribute information is transmitted to the exchange; Equipped with a function to transmit the terminal attribute information of the calling side terminal transmitted from the exchange to the terminal and display the attribute, and a function to register and maintain terminal attribute information transmitted from each terminal connection interface device in the exchange. By equipping each terminal, it is possible to know the attributes of the other party's terminal at the calling terminal without having to go to the installation location of the other party's terminal and conduct an on-site check, or without installing a telephone system etc. It can greatly contribute to labor saving and system cost reduction.
