Abstract
Methods of detecting a plug insertion into a plug aperture of a communications connector are provided in which a control signal is transmitted to a control signal input circuit of the connector that includes a reactive coupling element. The control signal is electromagnetically coupled through the control signal input circuit. The electromagnetically coupled control signal is thereafter detected on a first differential pair of conductive paths that are included in the connector. A determination is made that a plug is present in the plug aperture based at least in part on detecting the electromagnetically coupled control signal on the first differential pair of conductive paths.
