ABSTRACT:
A current limiting circuit for use in broadband and combined broadband and telecommunications networks is described. A current limiting element is triggered into a high impedance state in the event of excess current on the line. A sensing element detects the resulting decrease in voltage and operates a switch which disconnects the current limiting element. Timing circuitry reconnects the current limiting element a predetermined period of time after the current limiting element returns to its low impedance state.
