As shown in the figure, FIG. 2 shows three representative CASEs of ports in QDF equipment in a transmission room.

Case 1 shows a case in which one port of the QDF is used, and the case in which an arbitrary transmission equipment enters the exchange room through another transmission equipment via the transmission side port of the QDF.

In addition, Case 2 is a case where a plurality of ports of the QDF are used in three stages, and after the line enters the QDF transmission side port, it is divided into N lines through multiplexing equipment, and then connected to the N ports of the QDF again. Connections to exchange ports or other transmission equipment.

In addition, in case 3, two ports of the QDF are used, circuits bypassed internally in the exchange are interconnected through two switching side ports of the QDF.

Table 1 below shows the record structure of the facility table.

3 is a flowchart illustrating an embodiment of a method for constructing a transmission line circuit information database by introducing a pointer concept according to the present invention.

As shown in the figure, the information for each part constituting the service line is received from the outside. That is, the equipment and system names and information on ports used in the system are sequentially input from the transmitting side to the switching side with respect to the facility information on the transmitting equipment from the outside (301).

Thereafter, it is determined whether a record exists in the table of the corresponding transmission device for each port (302). If the record does not exist, a record for the current port is generated and the system name and port information are input (303). A transmitting side equipment name, a system name, and a port identification name (the transmitting side device pointing information) for the equipment are input to the generated record (306).

Thereafter, the exchange equipment name, system name, and port identification name (exchange equipment pointing information) for the exchange equipment to be connected to the current system are input to the generated record (307), and the current port is the transmit port in the transmitting equipment. It is determined whether the switching port exists (308), if the switching port exists, enter the switching port information in the switching port field (309), and if the switching port does not exist, whether the record generation is completed for all ports If it is confirmed (310) that the record generation is not finished, the process is repeated from the process of determining whether a record exists in the table of the corresponding transmission device for each port.

On the other hand, it is determined whether a record exists in the table of the corresponding transmission device by port (302). If a record exists, it is determined whether the port is used (304). If the port is in use, the user is informed that the port is already in use by another line. Require new information to be input (305), and if the port is not in use, starting from inputting the transmission equipment name, system name and port identification name (transmission equipment pointing information) for the transmission equipment connected to the current system. do.

Meanwhile, in the method of constructing a transmission line circuit information database by introducing a pointer concept according to the present invention, the ports used for each transmission facility through which the service line passes can be extracted with a single query to the database, and the service line passes in any direction. It is easy to maintain and manage connection information of ports for each transmission device.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

As described above, the present invention defines each device in a transmission room as a separate table, and adds attributes in the table that serve as pointers to devices and ports connected to the front and devices and ports connected to the back in each table. Therefore, the port of each device can be expressed simply and consistently in the system even if it is connected to any port of any device, and even if there is no special operation standard while operating different transmission devices according to the regional characteristics, there is a special restriction on equipment operation. It is possible to accept the current operation plan without any special load on the system and to provide all the relevant information necessary for failover in case of line failure through the database of the line information.
