Energy Detect with Auto Pair Select
First Claim
1. An energy detect with auto pair select system for device energy management comprises:
- a device operable to perform energy detection with auto pair selection;
a plurality of wire pairs 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;
wherein the device determines, with the qualified energy, whether at least one additional device is coupled to the device via at least one wire pair within the plurality of wire pairs; and
when no device is coupled to the device via the at least one wire pair within the plurality of wire pairs, the device performs auto power down.

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.
