Abstract

PURPOSE: A remote test method for private lines using an access function of a DCS(Digital Cross connection System) is provided to test private lines using a line access function of a DCS, instead of a private line access equipment. CONSTITUTION: A private line test operator drives a line test program to execute a remote test for a fault line using a DCS(301), searches for line associated information(302), and judges whether access using the DCS is possible(303). If it is impossible to access the fault line using the DCS, the operator generates a line access command using an RTU and controls a line access system(304). In case that it is possible to access the fault line using the DCS, the operator reserves a DCS communication route and generates a DCS control command to control the DCS(305). Then the operator confirms whether the access is successful(306). If the access is successful, the operator generates a measurement command to test the fault line connected to the RTU and transmits it to the RTU.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of a dedicated line management system to which the present invention is applied.

As shown in FIG. 1, the dedicated line management system includes a remote measuring device (RTU) for each telephone station via a line to enable a centralized test to determine the cause and the section of the failure when a service failure of the dedicated line occurs. (13) is installed, and the dedicated circuit management system (OS) and the telemetry device 13 are connected using the packet network 14. The leased line management system manages information related to the configuration of a leased line subscriber required for remote testing, a transit telephone station, a received measuring device, and a line access device by using a database 16.

Operators in charge of the leased line test use the operating terminal device 17 connected to the leased line management system to search for related information on the failure line. The server program of the dedicated line management system that supports the Graphical User Interface (GUI) type of client performed by the operating terminal device 17 is executed by the central control unit 15, and is remotely connected to the subscriber's information management function. It is in charge of controlling the located measuring device.

On the other hand, the database 16 includes information related to subscribers such as the address, terminal equipment, line speed, etc. of subscribers generated at the time of constructing a dedicated line, facility information of a telephone station, measurement device information that can be tested, and address information that can be accessed on a specific line. Etc., and provide the information necessary for the operator's failure determination test. Here, when the operator performs a test of the failure line, the server program establishes a communication path using the telemetry device 13 and the packet network 14 accommodated in the failure line. Since the packet network 14 has connected all the telemetry devices 13, end-to-end section testing is possible for all telephone stations in the country. The telemetry device 13 has various measurement functions for voice, digital, and high speed lines to determine whether a line is broken.

The access device 12 for the circuit test is in charge of the basic line connection function, and performs a line access function using the line connection function of the digital line distribution device (DCS) 11 and a dedicated line management system for this purpose. Sets the control path of the digital line distribution apparatus 11 and controls the digital line distribution apparatus 11 to access it. On the other hand, the subscriber's line can pass through some or all of the existing access device and the digital line distribution device.

2 is an explanatory diagram of a dedicated line remote test method using a connection function of a digital line distribution apparatus according to the present invention.

As shown in FIG. 2, when the test operator of the dedicated line performs a test of the failure line, the line test control function searches a database to establish a communication path for the telemetry device and the digital line distribution device, and For management, the test procedure and operator's test method are presented. In addition, it searches the database and performs the measurement device management function according to the route information of the line to be tested, and secures the communication path with the telemetry device connected to the packet network and accesses the telemetry device when not via the digital line distribution device. Various measurements are made on the circuits accommodated in the circuit access device.

At this time, the control of the line access device is in charge of the telemetry device. If the fault line is via a digital line distribution device, the line connection function of the digital line distribution device is used instead of the line access device to connect the line to the telemetry device. For this purpose, the digital line distribution device is controlled by securing a separate communication path from the telemetry device in the dedicated line management system.

At this time, the disconnection test of the circuit is required to determine the fault of the circuit, and the control procedures and procedures of the telemetry device and the digital circuit distribution device must be correctly performed.

3a and 3b is a flow chart of an embodiment of a dedicated line remote test method using the connection function of the digital line distribution apparatus according to the present invention.

As shown in FIGS. 3A and 3B, in order to perform a remote test of a failure line using the DCS 11, the dedicated line test operator runs a line test program (301) and then retrieves information related to the line (303). In operation 303, it is determined whether access using the DCS is possible.

If it is determined that access is not possible, generate a line access command using the RTU to control the circuit access device (304), and if access is possible, control the DCS by securing the DCS communication path and generating the DCS control command (305). Check whether the access is successful (306).

As a result of the check, the system is terminated if it fails, and if it is successful, a measurement command is generated and transmitted to the RTU for the test of the successful failure line connected to the RTU (307).

Subsequently, the measurement result is received, the result is analyzed and output to the operator's screen (308), and it is determined whether or not to change the access of the line under test (309).

As a result of the determination, it is determined whether the access is made using the DCS (310). If the access is made using the DCS, the control unit generates and controls a DCS control command (311), or generates and controls a line access command (312) and determines whether there is a failure. In step 313, it is determined whether to continue the line specification.

As a result of the determination, if no change is made, the process proceeds to step 313 in which it is determined whether to continue the line measurement for the determination of the failure.

As a result of the determination, if the measurement continues, the process proceeds to the step 307 of generating and transmitting a measurement command for the test of the successful failure line connected to the RTU. If the measurement is not continued, the measurement result is stored in a database and related to the test. The device is returned to its original state (314).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

In the present invention as described above, in a dedicated circuit remote test environment, by using the circuit access function utilizing the circuit configuration function of the DCS, by reducing the connection point for the circuit test, it is possible to fundamentally eliminate the cause of contact failure, etc. This eliminates the need for a circuit access device, greatly reducing the cost of a test environment.
