Abstract

PURPOSE: A method for synchronizing line information between private line management systems is provided to automatize associated work and synchronize data between systems by managing private lines using interworking modules in carrying out the new installation, modification and cancellation of private lines. CONSTITUTION: In order to accord line information, interworking modules(31,32) are provided between a DCS(Digital Cross connection System) management system(12) and a private line integrated management system(11). The interworking modules(31,32) make the DCS management system(12) inter-worked with the private line integrated management system(11). In case that an interval passing through a DCS in the route selection work of a line exists, the private line integrated management system(11) transfers information for the beginning and end of the interval to an interworking transmitting module(311) with the work order. An interworking receiving module(321) delivers it to the DCS management system(12). The DCS management system(12) executes the requested order. A work result is transmitted to an interworking receiving module(312) through an interworking transmitting module(322).

Description

Data consistency maintaining method between dedicated line management system

The present invention is to manage the line using the interlocking module in the operation of the line opening, change, termination, etc. of the leased line in a system in which heterogeneous leased line-related systems such as a total line management system and digital line distribution device management system interlocked The present invention relates to a circuit information matching method capable of automating related tasks and matching data between systems, and a computer readable recording medium storing a program for realizing the method.

1 is an exemplary configuration diagram of a system in which a general leased line comprehensive management system and a digital line distribution device management system are interworked. In FIG. 1, "11" denotes a dedicated line integrated management system and "12" denotes a digital line distribution device management system. Indicates.

As shown in FIG. 1, a system in which a general dedicated line integrated management system and a digital line distribution device management system are interlocked, a dedicated line integrated management system 11 and a digital line for operation, maintenance, test, and repair of a dedicated line. And a distribution device management system 12.

As shown in FIG. 1, the dedicated line is configured through various types of devices such as a station apparatus, a digital cross-connection system (DCS), an inter-station transmission apparatus, a test apparatus, and a termination apparatus. Here, for the operation, maintenance, testing, and repair of the leased line, the information about the subscriber and the information on the various types of devices must be comprehensively managed.

For this purpose, all information on the line is input through the leased line integrated management system 11 in the configuration stage of the leased line, and the leased line integrated management system 11 uses the information to test, maintain, change, Perform such work as termination. These systems enable network service providers to predict the degree of saturation and facility demand for leased line facilities and to maintain consistent information about line configuration, termination, and testing.

On the other hand, among the components of the leased line, the digital divider (DCS) plays a role as a kind of leased line exchanger and is in an important position in the operation of the leased line, unlike the other passive transmission devices due to the nature of the leased line. The equipment itself can provide the function of remote control through external interface, and it can output the judgment of its own facility failure or abnormality of input line.

By utilizing these functions of the system, the independent management system 12 of the digital circuit distribution device (DCS) can be configured, and through this system 12, the section of the section composed of the digital circuit distribution devices (DCS) of the entire section of the dedicated circuit can be configured. Can configure, terminate, change, test, etc. a circuit.

However, since the digital line distribution device management system 12 is an independent system of the dedicated line integrated management system 11, it is necessary to perform organic work processing and information sharing through interworking between the systems 11 and 12. .

The present embodiment proposes a method for performing related work through interworking between both systems 11 and 12 when such systems 11 and 12 exist for dedicated line business processing.

Amid the rapid wave of informatization of society, the demand for leased-line services, which have the advantage of maintaining security and guaranteeing a constant communication speed, is increasing in communication between corporations, government offices and individuals. In addition, in addition to the dedicated line provided to subscribers, network operators are managing the transmission network established in the company in the concept of a dedicated line for business, the importance of the integrated line integrated management system 11 is emerging.

As such, in order to comprehensively manage the leased line, a system for intensively operating overall data related to the leased line, such as the leased line comprehensive management system 11, is required. Information is operated.

However, in the construction of the dedicated circuit, the section consisting of digital circuit distribution devices (DCS) is developed by a device supplier or a user of the device to fully utilize the functions of the digital circuit distribution device. It is operated separately like system 12. The digital line distribution device management system 12 and the dedicated line integrated management system 11 exist for the related work, but human and physical waste due to the dual input and management of data when there is no organic interworking, and between the two systems. There is a high possibility of data inconsistency. This will be described in more detail with reference to FIG. 2.

2 is an explanatory diagram showing a conventional circuit configuration method, which is an example showing the flow of a circuit configuration operation in which an interworking function is not used.

As shown in FIG. 2, since the conventional dedicated line integrated management system 11 cannot utilize the automatic line configuration function provided by the digital line distribution device management system 12, the result of manual processing for each device is stored after the manual processing. Also, each device is inputted independently to the management system. In this case, the operator is burdened with inputting information into both systems 11 and 12 twice, whereby inconsistencies in data due to manual operation may occur between the systems 11 and 12.

As such, in the system in which the dedicated line integrated management system 11 and the digital line distribution device management system 12 are interworked, the dedicated line is a pulse code modulation (PCM) station device in the dedicated line service service of the network operator. It is composed of various types of devices such as transmission facilities such as optical devices and subscriber line devices such as digital line distribution devices such as DCS, data service units (DSU), and asynchronous digital subscriber line (ADSL). When a dedicated line is configured, data is input and operated independently in a separate system for each device. Therefore, there is a need for a method for eliminating data inconsistency and organically utilizing the unique functions of the respective systems.

The present invention has been made in order to meet the above requirements, such as the line opening, change, termination, etc. of the leased line in a system in which heterogeneous leased line related systems such as a leased line integrated management system and a digital line distribution device management system is interlocked. Provides a computer-readable recording medium recording line information matching methods for automating related tasks and matching data between systems by interlocking modules in the work, and a program for realizing the above methods. There is a purpose.
