Description

How to delete the trunk line information of the exchange

The present invention relates to a method for processing trunk line information at an exchange, and more particularly, to a method for collective deletion of trunk line information.

FIG. 1 is a block diagram of an exchange, where the central processing unit 111 controls call switching and controls the overall operation of the key telephone system to provide various services to a user. The memory unit 112 stores programs and initial service data of the central processing unit 111 for performing basic calls and various functions, and temporarily stores data processed by the central processing unit 111. The memory unit 112 includes a ROM for storing program and service data and a RAM for temporarily storing data generated during program execution. The input / output unit 113 performs an interface function between the central processing unit 111 of the exchange and the external input / output device. The interface unit 114 performs a function of interfacing data between the CPU 111 and each functional block of the exchange.

The switching circuit 115 switches various tones and voice data under the control of the CPU 111. The subscriber circuit 116 supplies a call current to a general telephone (not shown) under the control of the central processing unit 111 and simultaneously interfaces a signal between the general telephone and the switching circuit 115. The ring generator 118 generates a ring signal and supplies it to the subscriber line. Repeater 117 is connected to the subscriber circuit 116, and performs a relay function for switching the incoming and outgoing signals. The node trunk circuit 119 is connected to another switch with a trunk line when operating a private switching network, and functions to interface a signal transmitted and received through the trunk line. The trunk line circuit 120 forms a trunk line call loop by scissing a trunk line under the control of the CPU 111, and interfaces a signal between the trunk line and the switching circuit 115. Here, the trunk line refers to a line connecting the trunk line circuit 119 and the national exchange.

The tone generator 121 generates various tone signals under the control of the CPU 111 and outputs them to the switching circuit 115. The DTMF receiver 122 analyzes a DTMF signal input from the switching circuit 115, converts the DTMF signal into digital data, and outputs the digital data to the central processing unit 111. The DTMF transmitter 123 converts the digital data output from the CPU 111 into a DTMF signal and outputs the DTMF signal to the switching circuit 115. A signaling circuit 124 inserts or extracts signaling under the control of the CPU 111.

In FIG. 2, 2a is a diagram of a database of CO lines ID, each CO line has a size in bytes, and 2b is a diagram of a database of CO lines, each of which has word units.

In the switch having the above configuration, trunk ID and trunk port for interlinking trunk lines should be registered using RS 117. However, to delete the trunk line ID and the trunk line port, the trunk line ID is deleted from the trunk line menu and the trunk line ports are deleted one by one. At this time, up to 10 CO lines can be registered and operated in one CO line ID. Therefore, if 10 trunk lines are registered in the CO line ID, when deleting, the trunk line port must be repeated 10 times to delete all trunk lines.

As described above, when the trunk line ID and the trunk line port are deleted in the conventional exchange, the corresponding information may be deleted one by one. Therefore, up to 10 CO lines can be registered. Therefore, when deleting CO lines, the CO line should be deleted with the same operation 10 times. If only the trunk line port is deleted but the trunk line identification information is not deleted, when the subscriber inputs the trunk line ID through the telephone, the central processing unit 111 does not have any trunk line port corresponding to the trunk line ID, so that the subscriber side is controlled by calling the tone supply 121. Supply a busy tone.

Therefore, when deleting the CO line information, both the CO line ID and the CO line port should be deleted. Only when doing so, the central processing unit 111 of the exchange recognizes that there is no corresponding CO line ID and the corresponding CO line ports. However, as described above, the conventional CO line information processing method has to delete the CO line ID and the CO line port information one by one. In this case, it takes a long time to delete the CO line information. There was a problem that it operates to recognize that is registered.

Accordingly, an object of the present invention is to provide a method for collective deletion of trunk line information at an exchange.

Another object of the present invention is to provide a method of collectively deleting a trunk line ID and trunk line port information in a menu type switch in an interworking trunk line.

A method for collectively deleting trunk line information of an exchange according to an embodiment of the present invention for achieving the above object includes a memory storing a trunk line ID and a port database, and storing the trunk line information in the memory when a batch delete command is generated in a delete menu selection state. Access and delete the trunk line port information corresponding to the trunk line ID and the trunk line ID.

2 is a diagram showing a database of trunk line ID and trunk line port information;

3 is a flowchart illustrating a process of collectively deleting trunk line information according to an embodiment of the present invention.

According to an embodiment of the present invention, the configuration of the switchboard which performs the function of collectively deleting the trunk line ID and the trunk line port as the trunk line information is the same as that of FIG.

In addition, according to the embodiment of the present invention, the configuration of the database of the CO line ID and the CO line port information collectively deleted is the same as that of FIG.

3 is a flowchart illustrating a process of collectively deleting trunk line information in an exchange according to an embodiment of the present invention. Since a plurality of trunk line ports may be registered in one trunk line ID, a deletion function may be deleted from a trunk line ID menu to be deleted. In case of selection, the process of collectively deleting the CO line ID and CO line port is shown.

Based on the configuration of FIGS. 1 and 2, a process of collectively deleting trunk line information according to an embodiment of the present invention performed as shown in FIG. 3 will be described. In the embodiment of the present invention, it is assumed that up to 10 trunk line ports can be registered to one trunk line ID.

First, when the CO line ID and port information are registered or deleted, the relay line 117 is performed. In this case, the main menu is first displayed in step 311. When the registration menu is selected in the main menu display state, the selection of the registration menu is detected in step 312. When the registration function is selected, the CPU 111 inputs the trunk line ID and port information received in step 313 and registers the corresponding area of the memory unit 112. At this time, the trunk line ID and port information registered in the memory unit 112 are the same as 2a and 2b of FIG. 2. Thereafter, the CPU 111 performs an exchange function by interworking circuit lines in step 315.

However, when the delete function is selected in the main menu display state, the CPU 111 detects this in step 317 and outputs the CO line ID information registered in the corresponding area of the memory unit 112, and the relay station uses the CO line ID menu. Display. In this case, if the delete key is input, the controller detects this in step 321 and waits for input of the connection key in step 323. In this case, when the delete key and the connection key are sequentially generated while the CO line ID menu is displayed, the CPU 111 detects this and checks whether the pole line ID and the CO line port information exist in step 325, and if present, In step 327, the trunk line ID and the trunk line port are collectively deleted. However, if only the delete key is generated while the CO line ID menu is displayed, the CO line ID and the CO line ports selected on the currently displayed CO line ID menu are individually deleted.

Looking at the above operation to delete the CO line ID and port information according to the embodiment of the present invention, pressing the delete key while the corresponding CO line ID menu is displayed. Then, confirm whether to delete both the CO line ID and the CO line. If the connection key is generated, delete all the CO line ID and port information.

As described above, since the trunk line ID and port information can be deleted collectively at the exchange, it is possible to prevent an error that may occur when deleting the trunk line ID and port information one by one, and to perform the deletion time quickly. This allows the operator to easily perform the operation of registering or deleting the trunk line information that can be changed from time to time.
