ABSTRACT:
In one embodiment, an overvoltage protection circuit is disclosed for decoupling a voltage source available at a Subscriber Line Interface circuit (SLIC) from a subscriber loop line conductor when the voltage source is shorted to the conductor in a non-ringing condition. In another embodiment, a multi-point protection apparatus is provided for protecting a SLIC against transients having different levels.
