Here, the cable connected between the switch and the telephone subscriber is determined according to the relay method. Currently, optical cables, coaxial cables, and general telephone lines (that is, copper cables) are used.

In recent years, telephones have become so common that they are handled as necessities in ordinary homes, and the number of telephone subscribers installed in public workplaces and homes cannot be separated.

Therefore, in order to prevent cables that are connected between the exchange and the telephone subscriber from being cluttered, the middle line of the cables is collected and distributed using a rack. Such a rack collects the cables coming from the exchange side and distributes them to the telephone subscriber side through the cable connection board provided, and also distributes the cables coming from the telephone subscriber side and distributes them to the exchange side.

Conventionally, when testing cables connected between an exchange and a telephone subscriber, the cables were switched from the cable connection board of the rack and connected to an external test apparatus.

However, when testing the cable as described above, by switching the cable from the cable connection board of the rack, the communication service was interrupted, thereby causing a problem that the subscriber to the reliability of the communication service.

Accordingly, the present invention has been made to solve the above problems, in the implementation of the cable connection board for the middle line aggregation and distribution of the cables connected between a plurality of devices having mutual compatibility, without switching the cables The purpose is to provide a wiring device for testing that can be tested.

In addition, the present invention has another object to provide a connection device for a test that can provide a communication service even during the test of the cable by testing the cables connected between a plurality of devices having mutual compatibility without switching.
