Abstract

PURPOSE:To inform its own attribute information to an accumulating equipment only by the setting of a call on the accumulating equipment and to start instantly a data transmission on the receiving of a response by a user by informing the attribute information of an outgoing side data terminal with an incoming call signal. CONSTITUTION:A data terminal DTE-A performs an outgoing call according to the regular line exchange procedure against a line exchange equipment SW, dialing a subscriber's number given to the accumulating equipment CCE. The line exchange equipment SW, after requesting the attribute information of the outgoing data terminal DTE-A to an attribute information storing circuit REG-A corresponding to the data line of the outgoing data terminal DTE-A and obtains the attribute information, adds the said attribute information on the incoming call signal and informs the attribute information of the outgoing side data terminal of the receiving call to the accumulating equipment CCE using a terminal attribute transmitter/receiver CTL. At the accumulating equipment CCE, the attribute of the data line indicated by the incoming call signal is set by the attribute information received with the incoming call signal, and therefore, the data line to be used and the attribute of the outgoing side data terminal are coincided and, after the accumulating equipment CCE returns a response signal, a data communication can be instantly started.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a subscriber attribute notification system, and more particularly to a notification system for notifying data terminal attribute information to a storage device in a circuit exchange.

2. Description of the Related Art Conventional notification of originating data terminal attribute information to this type of storage device will be explained below with reference to FIGS.

Data terminal DTE and storage device CCE are connected to circuit switching device S
The storage device OCE connected to the terminal W is provided with terminal attribute detection circuits D/, Dco, and Dt corresponding to each connection line with the line switching device SW. By the way, data terminal DTE
Communication between the storage device 00E and the storage device 00E via the line switching device SW is assumed. No.! As shown in the sequence diagram in the figure, the data terminal DTE makes a call to the circuit switching device SW according to the normal circuit switching procedure, dials the subscriber number given to the storage device CCE, and calls the storage device (30). Set up a call path with.

Next, in order to notify the storage device Q (3E) of the terminal attribute information required for data transmission and reception, such as the speed and code of the originating data terminal, a terminal attribute detection circuit D/1 of the storage device Hacg called 1 hunting character is used. ,Dco,
In the storage device CCE, the character string (attribute information) determined by The terminal attribute detection circuit DI detects the attribute information of the received character, the speed of the transmitting data terminal, and the code HI, and stores it in the storage device 00.
It enabled data communication with the outgoing data terminal using E.

Another method is to fix the attribute to the data line for connecting the storage device 00 to the line switching device SW, and the originating data terminal DTE connects to the data line of the storage device OCR that matches its own terminal attribute. Data communication between the data terminal DTK and the storage device CCE was made possible by setting a call path through the single-line switching device SW.

Problems to be Solved by the Invention However, the conventional data terminal attribute notification method described above requires the data terminal user to input his or her own terminal attribute information for each call and notify it to the storage device. As a result, it takes time to set up the path until actual data transmission can start, and if the attributes are fixed for each data line of the storage device, division loss will occur due to the attribute assignment for the data line. Compared to a method in which attributes are determined for each call, this method has drawbacks such as requiring a large number of data cycles Ia.

The present invention has been made in view of the above-mentioned conventional circumstances, and
SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to overcome some of the drawbacks inherent in the prior art.

Means for Solving the Problems In order to achieve the above object, the terminal attribute notification system according to the present invention includes a line switching device connected to a data terminal and a storage device connected to the line switching device. In the switching system, the line switching device is provided with a data terminal attribute 1# information storage circuit, the line switching device 1 and the storage device are each provided with a terminal attribute 1R notification transmitting/receiving device, and f- Evening terminal and said 11! ! At the time of setting up a call with a terminal device, the attribute information of the data terminal is notified to the storage device by the terminal attribute information transmitting/receiving device 4+1 before lI.

Embodiment Next, a preferred embodiment of the present invention will be specifically described with reference to the drawings.

FIG. 1 is a block diagram for explaining a detailed implementation of the method according to the present invention. 3 and 3 are sequence diagrams for explaining this embodiment.

In the figure, data terminals 1'') TE-A, DTE-B, and storage device GCE are connected to line switching device SW via data lines, and storage device OGE further connects terminal attribute information transmitting/receiving device OTL via control signal lines. It is connected to the circuit switching device SW via the circuit switching device SW.
data terminal DTE-A.

Attribute information storage circuit RE for DTE-B data line support
G-A, RE (÷-B) are provided.

Next, assuming communication between the data terminal DTE-A and the storage device OCR via the line switching device SW, the operation of the system according to the present invention will be explained with reference to Figures 1 and 3. . As shown in the sequence diagram of FIG. 3, the data terminal DTE-A makes a call to the circuit switching device SW according to the normal circuit switching procedure and dials the subscriber number given to the storage device 00E. . The line switching device SW requests attribute information of the originating data terminal DTE-A from the attribute information storage circuit REG-A corresponding to the data line of the originating (4I) data terminal DTE-A, and after obtaining the attribute information, The attribute information is added to the incoming call signal, and the terminal attribute detection circuit [1, OTL is used to notify the storage device OCR of the originating data terminal attribute information of the incoming call. In the storage device OCE, by setting the attributes of the data line indicated by the incoming call signal using the attribute information received together with the incoming call signal, the attributes of the data line to be used and the originating data terminal become the same, and the attributes of the data line to be used and the originating data terminal are the same, and the attributes of the data line to be used and the originating data terminal are the same.
Data communication becomes possible immediately after the response signal is returned.

Note that the contents of the notification attributes according to this method include not only the character code of the data terminal and the transmission speed, but also the protocol to be used, screen control commands, format control characters, etc., which can be set in four ways.
