The present invention relates to a method for testing and repairing a track failure, and more particularly, to efficiently test and recover a failure on an internet connection line such as ADSL or VDSL on-line, thereby reducing the cost associated with troubleshooting and reducing processing time. It is about the method of testing and repairing the track failure that can be done.

With the rapid increase of the Internet population, costly testing and maintenance of the connection line is expensive, and customer dissatisfaction is caused by the delay in processing time.

In general, individual customers report failures even before checking the cause if they do not have access to the Internet. On-line tests such as line characteristics test (POTS) and EMS matching test are basically performed on the received fault report. If there is no problem, remote repair is performed by telephone call with the customer.

However, because most customers lack computer knowledge or bother to test on their own, they are finally dispatched to the field. Statistically, there is a problem in that the dispatch of the field dispatch accounted for more than 46% of the fault reports received, and therefore, a huge labor cost is required, and the processing period is delayed due to the congestion of the throughput, resulting in the purchase of customer complaints.

However, when actually dispatched to the field and checking the customer's computer, the authentication program is installed incorrectly or the web browser setting is wrong in most connection environments.

Therefore, if the telephone call with the customer can be handled sufficiently without the dispatch of manpower for the trouble that can be sufficiently remotely repaired, the labor cost can be considerably reduced and the reported failure report can be handled.

The present invention is presented by such a necessity, the object of the present invention is to check the connection environment on the customer's computer on-line without the dispatch of personnel to the failure report received from the customer to check whether the line is broken and recover To provide a way to do this.

Other objects, features, and advantages of the present invention will be clearly understood through the following embodiments.

According to an embodiment of the present invention, by connecting to a test device connected to the main wiring board (MDF) through a modem from the customer computer through communication with the customer to form an external closed loop consisting of the test device, the main wiring board and the customer computer Disclosed is a method for testing and repairing a track failure, which determines whether the physical condition is normal, and if it is normal, downloads and starts a diagnostic / recovery utility from a test apparatus to diagnose and recover the connection environment of a customer computer.

Preferably, in order to determine whether the foreign line is physically normal, the client computer may be temporarily assigned a test IP from the test apparatus.

Alternatively, the domestic flights may be tested by forming a domestic closed loop through the DSLAM port from the main distribution board prior to testing the overseas lines.

In addition, the diagnostic / recovery utility can be downloaded by entering the URL of the download server from the customer computer.

Preferably, the diagnostic / recovery utility performs network configuration of the client computer, removes and reconfigures a connected program, or restores the browser environment. More preferably, the diagnostic / recovery utility is provided with a remote support function to test the client computer. If a closed loop with the device is configured, the remote support function enables the real-time diagnosis and recovery status to be transmitted to the test device for display.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a network diagram showing a configuration to which the method of the present invention is applied.

The main distribution frame (MDF; Main Distribution Frame, 40) is connected to the test apparatus 30 according to the present invention. The test apparatus 30 includes an emulator, a line tester, a switching unit, and a control controller which basically perform a role of a modem or a digital subscriber line access multiplexer (DSLAM), and correspond to a plurality of main wiring boards 40, respectively. Connected.

The test apparatus 30 includes a certification server for functionally authenticating a connection from a customer computer, a billing server for calculating a cost according to service provision, a DHCP server for granting a test IP to a customer computer after a closed loop is formed, and a diagnostic / recovery utility. And a download server in which various drivers and connection software are stored.

The main circuit board 40 is connected to the digital subscriber line access multiplexer (DSLAM) 10 and the switch 20, and the foreign line is connected.

In addition, at the customer side, the modem 50 is connected to the outside line, and the modem 50 is connected to the customer's computer 70. Alternatively, an IP router 60 may be interposed therebetween.

According to the present invention, the track test can be largely divided into an extension test, an external test, and a connection test with a customer's computer.

2, an extension test method according to the present invention is described.

First, the main wiring board 40 is called from the test apparatus 30 and requests to block the foreign line and at the same time, requests for connection to the DSLAM 10 port (step S21).

When a connection to a plurality of DSLAM 10 ports is made, as shown by loop A in FIG. 1, a domestic closed loop consisting of the test apparatus 30-the main wiring board 40-the DSLAM 10 is formed ( Step S22).

In this way, when the domestic closed loop is formed, authentication and internet connection test are sequentially performed (step S23), and it is determined whether or not it is normal or fault based on the test result (step S24).

In addition, if necessary, the domestic closed loop may be configured as an exchanger 20-a main wiring board 40-a test apparatus 30 to test a dial tone and a dial function.

In case where it is judged normal by such domestic track test, overseas track test may be carried out.

3 is a flow chart showing an overseas track test according to the present invention.

First, the main wiring board 40 is called from the test apparatus 30, and a request is made to block the domestic flight, and at the same time, request the connection to the foreign line (step S31).

Subsequently, a telephone call with the customer is performed to access the test apparatus 30 from the customer's computer 70 through the web browser (step S32).

As a result, as indicated by a loop B in FIG. 1, an external closed loop composed of the test apparatus 30-the main wiring board 40-the customer computer 70 is formed (step S33).

As a result, a local area network (LAN) is constructed in which the test apparatus 30 becomes a server and the client computer 70 becomes a client, so that the client computer 70 is temporarily provided by the DHCP function from the test apparatus 30. IP is assigned.

Therefore, the Internet connection test can be performed on the customer computer 70 through the test IP (step S34).

Preferably, the connection test may be performed by performing a PING test using the test IP assigned to the customer computer 70 from the test apparatus 30 (step S35).

If the physical communication path is normal through such a connection test, the customer computer 70 can download and start the diagnostic / recovery utility from the test apparatus 30 (step S36).

That is, the customer can download the diagnostic / recovery utility by entering the URL of the download server of the test device 30. The download server can be placed separately from the test rig, and the URL of the download server can be obtained by a call to the test rig agent.

Subsequently, the diagnostic / recovery utility is installed and started automatically or by a click of a customer to diagnose and recover the connection environment of the customer's computer (step S37).

For example, a basic connection environment may be configured by performing a network configuration of a customer computer, removing and reconfiguring a connection program, and restoring a browser environment.

Meanwhile, the downloaded diagnostic / recovery utility can be installed as a single application on the customer's computer so that subsequent failures can be recovered in the same process.

In addition, when the closed loop is configured with the test device 30 by adding a remote support function to the diagnosis / recovery utility, the diagnosis and recovery status by the customer is transmitted to the test device 30 in real time through the remote support function and displayed. This can guide diagnosis and recovery.

By testing the line failures in this way, most of the failures caused by the connection environment of the customer's computer can be recovered on-line, thus reducing the enormous cost incurred by dispatching personnel to the site. The period can also be greatly reduced.

Although the above has been described with reference to the preferred embodiments of the present invention, various changes can be made at the level of those skilled in the art, and such changes can be said to belong to the present invention without departing from the spirit of the present invention. Therefore, the scope of the present invention should not be construed as being limited to the above embodiment, but should be determined based on the claims described below.

As described above, according to the present invention, a large maintenance cost due to dispatch of manpower is significantly reduced by solving the problem of incorrectly set connection environment of the customer computer, which takes up most of the failure report and is mainly solved by dispatching the site. There is an advantage that can be reduced.

In addition, since the test and recovery is performed on-line, the processing time per unit operation is short, and thus the period until processing after the failure report is shortened, thereby providing a rapid troubleshooting service.
