Abstract
A system and technique for detecting a device that requires power is implemented with a power detection station. The power detection system includes a detector having an output and a return which are coupled together by the device when the device requires power. The detector includes a word generator for generating test pulses for transmission to the device via the detector output, and a comparator for comparing the detector output with the detector return. The power detection station has a wide variety of applications, including by way of example, a switch or hub.

31. A transmission system, comprising:
-
a transmission line interface having at least one port;
a two-way transmission line comprising first and second conductors coupled to one of the ports; and
a device coupled to the two-way transmission line, the device selectively coupling the first and second conductors of the two-way transmission line together when the device requires power. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47)
