Such a network communication system checks a connection state between a network switch, a patch panel, and a communication tool or abnormality of a communication line connecting each of them in the installation, maintenance or repair process.

Conventionally, after establishing a network communication system by connecting between a network switch, a patch panel, and a communication port, a tester can be connected to the communication port, and a check can be made to check whether there is an abnormality in a communication line connecting the patch panel and the communication port. When the number of patch cords is large, it is difficult to identify the patch cord connecting the patch panel and the communication tool, and it was not possible to intuitively determine whether there is a communication line abnormality by the patch cord between the patch panel and the communication tool. In addition to the connection of the water polo, the connection between the network switch and the patch panel had to be checked separately.

In addition, in the conventional tester system, even after constructing a network communication system by connecting a network switch, a patch panel, and a communication tool, the port link information of each communication tool is collected using ^, and based on the information of the network switch. There was no way to perform network management collectively on the communication tool side such as assigning to each communication tool or collecting link information of each communication tool remotely.

As described above, the network management device 50 is connected to the network switch 10, the patch panel 20 and the communication port 30 or a communication line by a communication cable connecting each ( A pair of lighting units may be provided as the identification means for determining whether the abnormality of the 210 and 310.

Specifically, the identification means may be composed of a pair of lighting units (5¼, 5: ratio) which are different in current direction as light emission conditions and connected in parallel on a test voltage application path of the network management apparatus.

The lighting unit 51 may be configured to include 1 ^ 0 elements, respectively.

Communication cables connecting the network communication system (1), respectively

The communication cable may be provided with four pairs of communication lines, and in the network management apparatus, a test voltage may be supplied through two communication lines of four pairs. A pair of lighting units as the identification means of the network management apparatus 50 (5, 2019/208973 1 »（： 1 ^ 1 {2019/004759

5; ratio may be connected in parallel so that the current directions of light emission conditions are opposite to one of the two communication lines for the test voltage application.

The network management apparatus 50 shown in FIG. 3 is shown to apply a voltage through communication line 3 and communication line 6 of one pair of communication lines of 4 pairs of communication cables, but this is only an example and is not limited thereto. It doesn't work.

The lighting unit included in the network management apparatus may include a first lighting unit 5 and a second lighting unit 51, and the first lighting unit 51å0 is a current applying direction to the third communication line. It is connected in the forward direction and the second lighting unit (5¾) may be connected in parallel with the current application direction in the reverse direction.

In addition, the patch panel 20 constituting the network communication system 1 according to the present invention also has the third direction in the same direction as the second lighting unit 5, i.e., in the reverse direction of the third communication line in the network management apparatus 50. The lighting unit 21 may be further provided.

The third lighting unit 21 provided in the patch panel 20 may be mounted in a manner that is selectively turned off or lit depending on whether the plug of the communication cable connected to the network switch 10 is mounted.

That is, the third lighting unit 21 is connected to the third communication line 210 (3 (3) so as to be turned on when the plug of the communication cable connecting the network switch 10 and the patch panel 20 is not attached to the patch panel 20. )) And the sixth communication line (210 (6)) is connected, and when the plug of the communication cable connecting the network switch (10) and the patch cord is mounted, the plug-in switch that the above circuit connection is released Is mounted on the connection circuit. 2019/208973 1 »（： 1 ^ 1 {2019/004759

14 Whether the first lighting unit 513 to the third lighting unit 21 emits light when a test voltage is applied by the network management apparatus while the patch panel 20 and the communication tool 30 are connected by a communication cable. It can be determined as shown in Table 1 below.

That is, as shown in Table 1 below, when the cross-test voltage is applied through the network management device, depending on whether the first lighting unit 513 to the third lighting unit 21 is turned on in three cases Can be distinguished.

The test voltage applied by the network management device 50 test voltage applying unit of the present invention may be alternately applied to the communication line 3 and the communication line + + by a crossover voltage of a waveform or pulse shape.

In case 1, when the first lighting unit 5 is turned off and the second lighting unit 5 and the lighting unit 21 are turned on, the second lighting unit 3 is turned The plug of the communication cable connecting the patch panel 20 and the network switch 10 constituting the network communication system according to the present invention through the lighting state of the lighting unit 21 is not mounted on the patch panel 20 side. In this case, the test voltage applied through communication line 3 and communication line 6 turns on the second lighting unit (5¾) and the third lighting unit (21) which match the current direction.

In this case, the first lighting unit 513 is not turned on because the current direction of the light emission condition is opposite to the second lighting unit 5¾ and the third lighting unit 21.

In this case, at the same time as the second lighting unit (5¾) of the network management device 2019/208973 1 »（： 1 ^ 1 {2019/004759

15 When the third lighting unit 21 of the patch panel 20 of the new room is lit together, the operator has no problem in connecting the communication port 30 and the patch panel 20, but the network switch 10 and the patch Since it is possible to identify that the panel 20 is not connected, it can be confirmed that the connection work between the network switch 10 and the patch panel 20 in the communication room is required, which can be used as a work instruction function.

In case 2, when the first lighting unit 5 is turned on and the third lighting unit 21 is turned off, this is the network in the patch panel 20 and the patch panel 20 at the communication tool 30. Each connection state of the switch 10 is normal, and means that the communication line from the communication tool 30 to the network switch 10 is normal.

In this case, when the network switch 10 and the patch panel 20 are connected, the closed circuit connecting the network management device and the patch panel 20 is released and the third lighting unit 21 is not turned on.

In case 2, since the communication tool 30 and the network switch 10 are connected to form a closed circuit, the first lighting unit (5 ratio) and the second lighting unit (within 5) do not stir together when the cross voltage is applied. The reason is that the current required to turn on the second lighting unit 5113 is grounded while passing through the grounded network switch 10 so that no current is applied to the second lighting unit 5¾.

In case 3, when the entire first lighting unit 513 to the third lighting unit 21 is turned off, it means that a problem such as disconnection of a line in a specific area among the communication lines shown in FIG. 2 occurs. 2019/208973 1 »（1 ^ 1 {2019/004759

16 That is, a function of indicating that a problem such as disconnection or failure has occurred on a communication line formed by a communication cable connecting the communication tool 30, the patch panel 20, and the network switch 10 from the network management device. This allows the system check work instruction to be performed.
