A modular jack circuit (100) is diposed between a cable side (10) for connecting with a mating plug and a physical side (20) for connecting with a mother board. The moular jack circuit comprises a first transmitting channel and a second transmitting channel. The moular jack circuit includes a number of filtering electronic elements (2, 3) and a number of relays (1, 4) disposed between the filtering electronic elements and the cable side. The first and second transmitting channels share the filtering electronic elements. The relays control the filtering electronic elements to transmit signals for the first and second channels at different times. |
