Abstract:
1. An energy detect with auto pair select system, comprising: a device that is operable to perform energy detection with auto pair selection; a plurality of wire pairs that is communicatively coupled to the device; and wherein the device generates a qualified energy by considering an energy associated with at least two wire pairs within the plurality of wire pairs and subtracts a link pulse energy from the energy when the device transmits a link pulse to generate the qualified energy, the link pulse energy is associated with the link pulse that is transmitted from the device; the device uses the qualified energy to determine whether at least one additional device is communicatively coupled to the device via at least one wire pair within the plurality of wire pairs; and the device performs auto power down when no device is communicatively coupled to the device via the at least one wire pair; and an OR gate that sums energies on each of the plurality of wire pairs; and an AND gate that suppresses the link pulse energy from the sum of the energies of each of the plurality of wire pairs.
