Abstract: A protector module for use with a communication system, such as a telephone system having a tip line and a ring line, includes a base member and a plurality of electrically conductive pins mounted on the base member. A first electrical contact is fixedly mounted on the top surface of the base member and is in electrical communication with one of the tip line and the ring line. A movable second electrical contact is connected to a ground pin mounted on the base member and is situated in alignment with the first electrical contact. A solder pellet, which may melt in high current, long duration power surges, and a solid state device, are positioned between the first and second electrical contacts.

Abstract: A wire termination block includes at least one conductive contact; and a body having a base portion and a driving portion, the driving portion having a plurality of apertures for receiving wires and being operable in at least two driving modes to terminate and couple a received wire to the conductive contact. One of the two driving modes may be operable with a tool and the other of the two modes is operable without a tool by a user. For example, the driving portion may include a lever driven mechanism for terminating and coupling the received wires in a first of the two driving modes and a bolt driven mechanism for terminating and coupling the received wire in a second of the two driving modes. The conductive contact may be insulation displacement connector or contact (IDC).

Abstract: A wiring error detection circuit for providing the status of the wiring of an AC outlet and the status of the AC outlet's ground connection.

Abstract: A modular device for a telephone network interface apparatus having separate connection and plug-actuated testing compartments. The compartment for connection having at least one pair of contact wires for connection to a subscriber premises line and at least one pair of contact wires for connection to an incoming telephone company line, and an arm member mounted for insertion in the connecting compartment and into engagement with the subscriber and telephone company contact wires effecting the connection between the pair of subscriber contact wires and the pair of telephone company contact wires and for being withdrawn from the connecting compartment causing the subscriber contact wires to be disconnected from the telephone company contact wires to provide a point for demarcation therebetween.

Abstract: A fusible link device comprising a housing that contains terminals for terminating incoming/outgoing wires, and that also contains a fusible link that interconnects a pair of the terminals in series, the fusible link device providing a self-contained unit/module for terminating and fusing wires to be electrically interconnected in series. The housing includes ports for inserting the wires that terminate on the terminals. These ports may be environmentally protected, such as by gel-sealing. The terminals may be implemented as insulation displacement connectors for connecting the wires and/or the fusible links. In one implementation, the fusible link device may contain a total of four of the terminals and two fusible links for terminating and fusing the tip and ring lines in a telecommunications network. The fusible link device may also include one or more voltage protection devices, of the same or different type, electrically connected across terminals that are not series connected to each other.

Abstract: A wiring error detection circuit for providing the status of the wiring of an AC outlet and the status of the AC outlet's ground connection.

Abstract: A grounding module comprising a housing, an AC plug, a female outlet, a ground sensing-circuit for determining whether or not a ground is present when the AC plug is inserted into an AC outlet and an external ground connection for providing the ground to an electrical device.

Abstract: A system for protecting networks from overvoltage and overcurrent conditions.

Abstract: Power line surge protection device comprising AC power line overvoltage protection, telephone voice line overvoltage and overcurrent protection, high speed data line overvoltage and overcurrent protection, coaxial transmission line overvoltage protection, and a ground-sensing indicator, all tied to a common ground.
