Abstract
A transceiver, TX/RX PHY, arranged for bi-directional data communication of a node with a counterpart node connected to a point-to-point network using differential mode signaling over a single twisted-pair cable is disclosed. The transceiver, TX/RX PHY, includes a common mode choke arranged between of the TX/RX PHY and the single twisted-pair cable and provided for common mode current suppression. Further included is a switching arrangement arranged between the TX/RX PHY, the common mode choke and the single twisted-pair cable and configured to switchably change a polarity of one of the windings of the common mode choke. A detection section is included and coupled via the switching arrangement to the common mode choke and configured to detect a common mode signal on the single twisted-pair cable in response to a transmission of a test signal by the counterpart node.
