Abstract
An inexpensive and low power consumption power control unit that does not require a separate interface or network. In the power off state only a detector and a power controller require power, this power is supplied from a power source. Upon detection of traffic a frame decoder is powered up to receive frames. When the link is quiet, the decoder is powered down while the power controller and receiver remain powered and await further traffic.
