APPARATUS AND METHOD FOR DETECTION OF OFF-HOOK PHONE IN REVERSE POWER FEEDING ARCHITECTURE |
摘要 |
<p>A powering arrangement for use with reverse power feeding arranged to detect an improperly connected POTS phone going off-hook by: measuring a first current flow from a power sourcing equipment; identifying a rapid first increase in current flow from the measured first current flow, the rapid increase defined as a rate of change greater than a predetermined minimum rate of change; identifying a second increase in current flow from the measured first current flow, the identified second increase greater than a predetermined minimum amount; confirming that the identified second increase in current flow is maintained for at least a predetermined amount of time beginning with the identified first increase in current flow; and outputting an error signal to the power sourcing equipment in the event of the identified condition.</p> |
