Abstract: A system and method for testing a transmission line to a protected system includes measuring voltages between a tip-side node of an overcurrent protection device and the protected system, between a ring-side node of the overcurrent protection device and the protected system, between the tip of the transmission line and the protected system, and between the ring of the transmission line and the protected system. Using the measured voltages, the status of the overcurrent protection device and the overvoltage device may be recognized, and the magnitude of a voltage surge on either of the tip and ring wires may be determined.

Abstract: A telephone system includes a transmission line for connection to at least one telephone and a telephone interface in communication with the transmission line. The telephone interface provides DC power when a telephone connected to the transmission line is in an off-hook state. A controller in communication with the telephone interface generates a pre-defined DC characteristic of the telephone interface, and a regulator in communication with the controller adaptively translates the DC characteristic.
