`ABSTRACT
`(57)
`A Ba seT Ethernet system having a piece of central network
`equipment, a piece of Ba seT Ethernet terminal equipment,
`and data signaling pairs ofconc uctors having first and second
`pairs usec to carry BaseT F,thernet communication signals
`between the piece ofcentral network equipment andthe piece
`of BascT Ethernet terminal equipment. The first and second
`pairs physically coimect between the piece ofBascT Ethernet
`terminal equipment and the piece of central networ< equip-
`ment. The piece of central network equipment having at least
`one DC supply. The piece of BaseT Ethernet terminal equip-
`ment having at least one path to draw different magnitudes of
`current flow from the DC supply through a loop formed over
`at least one of the conductors of the first pair and at least one
`of the conductors of the second pair. The piece of central
`network equipment to detect at least two different magnitudes
`of the current flow through the loop.
