Abstract
A low cost mechanism that may be used to extend Ethernet capability to low end devices provides sufficient capacity to support Ethernet communications using only a single twisted pair medium. Because only a single twisted pair is used, the overall cost, complexity and size associated with the integrating Ethernet functionality into an end device is reduced. A distributed power system delivers power to a Data Terminal Equipment (DTE) device over the single twisted pair medium. With such an arrangement, Ethernet capability and power may be simultaneously delivered to low end devices at a reduced cost.
