FIELD: electricity. ^ SUBSTANCE: system of group electric wiring includes concentrator of server system, distributing frame including many connectors of wire pair, many remote connectors, test device and many test circuits. Each test circuit is connected between conducting wires and contacts of connector of network pair. Each test circuit includes device of light-emitting means and filtering device. Light-emitting device emits the light when the test device supplies test voltage to contacts. Test voltage is low-frequency voltage signal having frequency within 100 kHz and 3 MHz, which creates impedance of the circuit, which is higher than that of filtering device by means of which the voltage signal when passing through concentrator decreases and is filtered, and test of arrangement is performed, while server is in on-line mode. Also, method for arrangement of wire pairs in system of group electric wiring is described. ^ EFFECT: increasing efficiency and quick operation of determination of wire pairs location. ^ 4 cl, 4 dwg |
