Abstract

PURPOSE:To quickly execute the switching and the connection of many lines by making information required for the switching and the connection of the line into a data base beforehand, and in addition, holding data in every line switching connecting part. CONSTITUTION:In the case where the line 7 falls into line disconnection on account of the trouble of a transmission line, when a control part 19 starts line switching control, the discrimination number of the data corresponding to said control is transmitted as a message to line switching control parts 16, 17 and 18. The line switching control parts 16, 17 and 18 extract the data corresponding to the discrimination number from data base parts 13, 14 and 15, and drive the line switching connecting parts 10, 11 and 12. Thus, a line between a terminal 1 and the terminal 2 having fallen into the line disconnection can be connected through the line 8 and the line 9.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a line switching control system, and in particular to a method for backing up a large number of faulty lines in a large-scale communication network consisting of a large number of transmission lines in various fault situations. This invention relates to a line switching control system that can respond to each and perform it quickly.

Conventional technology Conventionally, in this type of line switching control system, a line switching connection unit is installed at each important node in a communication network where multiple transmission lines are concentrated, and a central operator selects the terminals and lines or lines to be connected. The controller then analyzes the information into cross-point on/off information for the line switching connection, transmits the information to the necessary line switching connection, and switches the line.

Problems to be Solved by the Invention In the conventional line switching control system described above, an operator inputs information about the connected line during control, and the control unit uses that information to perform switching corresponding to each crosspoint of the line switching connection. Since the data is decomposed into data and then transmitted to each line switching connection section via the line, there is a drawback that it takes a long time to switch and connect the lines.

The present invention has been made in order to eliminate the above-mentioned drawbacks inherent in the conventional technology, and therefore, an object of the present invention is to provide a new line switching control method that makes it possible to quickly execute a large number of line switching connections. Our goal is to provide the following.

Means for Solving the Problems In order to achieve the above object, line switching i#1 according to the present invention
The 1g1 system consists of a means for performing line switching connection, a means for storing line switching connection data necessary for the line switching connection, a means for driving line switching connection using the line switching connection data, and one communication. and means for centrally controlling line switching connections for the entire network.

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

FIG. 1 is a block diagram showing one embodiment of the present invention.

Referring to FIG. 1, reference numbers 1, 2, 3, 4, 5, and 6 indicate terminal devices, respectively, and these terminal devices are connected to different transmission lines 7, 8, and 9 on the communication network, respectively. They are connected by switching connection parts 1O111 and 12. Reference numerals 13, 14 and 15 are database units, which store data for switching and controlling the cross points of the line switching connection units 10, 11 and 12, with data for the same control assigned the same identification number. During control execution, the line switching control units 16, 17 and I8 control the control unit I.
Upon receiving the message of the data identification number from the database section 9, data corresponding to the identification number is taken out from the database sections 13, 14 and 15, and the line switching connection sections 10.11 and 12 are driven.

In FIG. 1, when one line 7 is disconnected due to a fault in the transmission path, when line switching control is activated by the control unit 19, the identification number of the data corresponding to the control is sent as a message to the line switching control unit 16. .17 and 18. When the line switching control units 16, 17 and 18 receive the message, they retrieve data corresponding to the identification number from the database units 13, 14 and 15, and drive the line switching connection units 10-11 and 12. The line switching connection unit 10 disconnects the terminal 1 and the line 7 and the terminal 3 and the line 8,
A single-line switching connection unit 11 that connects the terminal 1 and the line 8 disconnects the line 8 from the terminal 4 and between the terminal 5 and the line 9, and connects the first line 8 and the line 9. Then, the two-line switching connection unit 12 disconnects the line [7 and the terminal 2 and the line iI9 and the terminal 6, and connects the first line 9 and the terminal 2.

As a result of the above operation, the terminal 1 and the terminal 2, which had one line disconnected, are connected via the line 8 and the line 9.

As described in detail, according to the present invention, by creating a database in advance of the information necessary for one line switching connection and storing data for each line switching connection, it is possible to quickly perform a large number of line switching connections. You can get actionable effects.

Claims (1)

[Claims] In a line switching control method for backing up faulty lines in communication networks, the information necessary for line switching connections is created in advance in a database for each line switching control, and is used in the same line switching control for each line switching connection. All the data to be transferred are assigned the same identification number and stored in a distributed manner, and the line switching connection is performed by transmitting the identification number of the data from the control unit to the line switching connection unit.
