Abstract
Detecting a signal disruption of an AC-signal by a DC-current in a powered networking system includes receiving an AC-signal from the networking system; analyzing the AC-signal based on a predetermined characteristic of the AC-signal and generating an analysis output; then comparing the analysis output with a predetermined reference source wherein the comparing detects the AC-signal disruption in the powered networking system.
Claims48
A detector system for detecting a signal disruption of an AC-signal by a DC-current in a powered networking system, said system comprising:
- a signal analyzer subsystem in operative electrical communication with said powered networking system, said analyzer adapted to receive said AC-signal from said networking system and to analyze said AC-signal based on a predetermined characteristic of said AC-signal and to generate an analyzer output;
- and
- a comparator subsystem in operative electrical communication with said analyzer subsystem, said comparator adapted to receive and to compare said analyzer output with a predetermined reference source so as to detect an AC-signal disruption and determine if said AC-signal disruption is caused by the DC current.
A method for detecting a signal disruption of an AC-signal by a DC-current in a powered networking system, said method comprising:
- receiving an AC-signal from said networking system;
- analyzing said AC-signal based on a predetermined characteristic of said AC-signal generating an analysis output responsive to said analyzing;
- and
- comparing said analysis output with a predetermined reference source to detect said AC-signal disruption in the powered networking system and determine if said AC-signal disruption is caused by the DC current.
