Title:
SYSTEM AND METHOD FOR DETECTING A DEVICE REQUIRING POWER
Document Type and Number:
WIPO Patent Application WO2001011861
Kind Code:
A3
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.
