The present invention relates to a relay device constituting a line for a high-speed Internet failure test, a failure test system and a failure test method using the same.

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 that out-of-site dispatch accounts for more than 45% of the fault reports received, which requires enormous labor costs and delays the processing period due to congestion.

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.

Due to this necessity, Patent Application No. 2004-0038381 issued by the present inventor is a communication device with a customer. Forming a closed loop, it is determined whether the foreign line is physically normal, and if it is normal, it suggests a line failure test and recovery method that downloads and starts the diagnostic / recovery utility from the tester to diagnose and restore the connection environment of the customer's computer. .

Modem unit 50 may be connected to a separate existing modem, it may be integrally installed as a modulation and demodulation unit in the relay device 40, when considering the installation, expandability, it is preferable to use a separate existing modem connection.

As shown in FIG. 1, the input / output interface 44 has connection ports 43 and 43a for connection with the input port 41, the uplink input port 42, and the modem 50 connected to the DSLAM 30. ) And the UI port 43b for communicating with the test server 100.

The relay device 40 is installed in an unmanned station, such as the DSLAM 30, and the number of input ports 41 and uplink input ports 42 connected to the DSLAM 30 are installed in the unmanned station DSLAM 30. Corresponds to the number of.

In addition, the connection ports 43 and 43a connected to the modem 50 may support both 10Tx and 100Tx.

The switching units 45, 46, and 47 may apply a matrix switch, and may be configured using a relay and an analog switch. In this example, assume that up to 16 DSLAMs (30) are installed in an unmanned station, and up to three modems of different types are connected to the relay (40). (46) and 4 X 1 matrix switches 47 were applied respectively. However, switch 46 is not necessary if there is no redundant uplink port 34 in DSLAM 30 or if it is not used.

The switching units 45 and 47 switch the DSL input from the test port 36 of the DSLAM 30 to the modem 50 under the control of the control unit 48, and output the DSL output from the modem 50. Switch to connect to the test server 100. In addition, the IP packet from the uplink port 34 is optionally provided to the test server 100 through the switching units 46 and 47 to construct an IP packet direct test path.

The tester recognizes the configuration of the DSLAM 30 connected to the EMS (Element management System) 110 through the EMS terminal or the EMS matching and distributes the subscriber line, and checks the input port 32 into which the subscriber line is input. Internally with

Optionally, if an extra uplink port 34 is secured, the input port 33 through which the subscriber line is distributed to the subscriber modem 20a may be internally connected to the uplink port 34.

At this time, since the outputs from the test port 36 or the uplink port 34 are connected to the DSL input port 41 and the uplink input port 42 of the relay device 40, respectively, the subscriber modems 20 and 20a. The modulated DSL output or IP packet output from) is optionally input to the corresponding port.

That is, inside the DSLAM 30, the DSL input from the subscriber modems 20 and 20a is converted into an IP packet and processed. The test port 36 converts the DSL input back to DSL and outputs it to the uplink port 34. Output IP packets as they are.

In the relay device 40, the control unit 48 extracts configuration information of the DSLAM 30 and the subscriber modem with reference to the database for the DSL input from the test port 34, and controls the switching unit 45 based on this. To output the DSL input to the corresponding modem 50 to switch to demodulation in the modem 50, or to control the switching unit 46 to switch the IP packet from the uplink port 34 to the test server 100. do.

For example, if subscriber modem 20 is an ADSL modem and subscriber modem 20a is a VDSL modem, the DSL input from subscriber modem 20 is switched to a conversion ADSL modem, and subscriber modem 20a is used for conversion. Switch to VDSL modem. In addition, even if the subscriber modem is the same VDSL modem specification may be different, in this case, to connect to the corresponding VDSL modem with reference to the database.

In this way, the modulated DSL input from the subscriber modems 20 and 20a is demodulated by the conversion modem 50 connected to the relay device 40, and is then converted into an IP packet by the control unit 48 to be used as the test server 100. Is sent).

Thus, the test server 100-the control unit 48 of the repeater-the switching unit 45, 46, 47 of the repeater-the test port 36 or uplink port 34 of the DSLAM 30-DSLAM 30 A line consisting of the input ports 32 and 33 of the subscriber station, the subscriber modems 20 and 20a, and the subscriber computers 10 and 10a is configured so that the tester can test the line failure through the test server 100.

That is, a closed-circuit network composed of the test server 100 and the subscriber computer 100 is configured to sequentially perform authentication and internet access tests, and determine whether the test server 100 is normal or malfunctioning based on the test results.

At this time, the control unit 48 receives the subscriber ID and password from the subscriber modem (20, 20a) and performs the authentication and delivers the results to the test server 100, and provides the test IP to the subscriber for the subscriber is not authenticated By connecting to the test server so that the test server 100 can perform the diagnostic and repair work for the subscriber.

In addition, when there is no subscriber authentication, the control unit 48 may transfer the test IP temporarily assigned by the DHCP function to the subscriber computers 10 and 10a and perform an internet access test through the test IP.
