Abstract
Energy detect with auto pair select for energy management without ‘a priori’ knowledge of the wire pairs connectivity. The energy detect with auto pair select is operable within systems performing automatic detection of connectivity in systems that employ the Ethernet based media dependent interface crossover (MDIX). Where there has been some cross-over of pairs within the system, a situation not uncommon in many networks, the energy detect with auto pair select is operable to perform energy management without knowledge of the pair connectivity. Selection or detection of coupled wire pairs is acquired by energy detection of coupled wire pairs via a state machine that analyzes a qualified energy level.
