Abstract
A network connection device having internal circuitry capable of wiring correctly to a network cable is described. The network connection device includes an interface circuit, a switching array and a controlling circuit. First, the network connection device is physically connected to the network cable. Next, the positive and negative receiving terminals in the interface circuit are connected to a pair of signal carrying wires through the device's internal circuitry. Depending on the returned preamble field, the connections to the signal-carrying wires are judged to be either incorrect, in which case the connection has to be swapped through device's internal circuitry, or correct, in which case no swapping is required. Subsequently, the positive and negative transmission terminals are connected to a second pair of wires inside the network cable. Next, a data packet is sent out through the transmission terminal. According to the acknowledgement packed returned, the connections to the second pair of wires are judge to be either incorrect, in which case the connection has to be swapped through device's internal circuitry, or correct, in which case no swapping is required.
