Telecommunications conductor wire pair test circuits are provided. The test circuits include a switch electrically coupled to the wire pair. The switch has a first position in which the test circuit provides an open circuit across the wires of the wire pair and a second position in which the test circuit is detectable across the wires of the wire pair. An energy storage cell is electrically coupled across the wires of the wire pair so as to charge the energy storage cell when the switch is in the second position. The switch is powered by the energy storage cell. An energy monitor circuit is electrically coupled to the energy storage cell which detects an energy level of the energy storage cell. A switch control circuit switches the switch from the first position to the second position responsive to the energy monitor circuit. In other embodiments, the switch is a relay and the energy monitor circuit is optionally included. Methods are also provided using the test circuit.

Remotely operable telecommunications conductor test circuit and method for using the same

An overvoltage protection device includes a housing including a first substantially planar electrical contact surface and a sidewall. The housing defines a cavity therein and has an opening in communication with the cavity. An electrode member of the device includes a second substantially planar electrical contact surface facing the first electrical contact surface and disposed within the cavity. A portion of the electrode member extends out of the cavity and through the opening. A wafer formed of varistor material and having first and second opposed, substantially planar wafer surfaces is positioned within the cavity and between the first and second electrical contact surfaces with the first and second wafer surfaces engaging the first and second electrical contact surfaces, respectively.

Overvoltage protection device including wafer of varistor material

An overvoltage protection device includes a first electrode member having a first substantially planar contact surface and a second electrode member having a second substantially planar contact surface facing the first contact surface. A wafer formed of varistor material and having first and second opposed, substantially planar wafer surfaces is positioned between the first and second contact surfaces with the first and second wafer surfaces engaging the first and second contact surfaces, respectively. The contact surfaces may apply a load to the wafer surfaces. Preferably, the electrode members have a combined thermal mass which is substantially greater than a thermal mass of the wafer. The wafer may be formed by slicing a rod of varistor material. The device may include a housing including the first substantially planar contact surface and a sidewall, the housing defining a cavity within which the second electrode is disposed.
