Abstract: A safety protection system and a related operational method for the electrical protection of users of XDSL communication circuitry. The system is based on continuous monitoring of the current parameters on both the exchange and the remote subscriber ends of the XDSL communication system. The safety protection system samples, digitizes and compares the currents at both XDSL communication system ends. The measured currents are compared to specific limiting current and currents difference levels, based on the relevant safety requirements. Whenever required, based on the measured currents status, the safety system shuts down the XDSL communication system, or limits its maximum current. In another embodiment of the invention the safety system is based on continuous monitoring of the voltages related to ground of the two system communication wires, on one or both of the exchange and the remote subscriber ends of the XDSL communication system. The safety system compares the measured voltages and limits the XDSL system current to a safety protected level, if one of the wire voltages is different by at least a predefined voltage increment related to the second wire voltage.

Abstract: A method and/or device that may be used in locations where equipotential bonding is not practiced can be installed on a customer premises equipment device basis that provides over-voltage protection between the AC main and HFC ground planes. According to one aspect of the present invention, a bonding link is established between the AC main and the HFC coaxial braid that allows energy surges to bypass the CPE equipment and to be passed on to the AC mains, which are traditionally more equipped to deal with these large energy surges. According to another aspect of the present invention, an apparatus is disclosed that may be incorporated into any premises powered HFC CPE device for protection. The apparatus provides a surge energy bypass path around the CPE device being protected and allow voltage differentials to be normalized between systems.

Abstract: A protection arrangement for a telephone subscriber line interface circuit is disclosed. The arrangement is particularly useful for protecting an electronic telephone set from over-voltage and over-current fault conditions. The arrangement provides a FET that operates in saturation mode to connect an office battery to the subscriber line under normal operation. The FET also provides isolation capabilities for protecting the line circuit from an over-current condition on the subscriber line. Over-voltage protection is provided by way of an isolation relay between the line circuit and the subscriber line. Both the FET and isolation relay are operated by a controller that uses timers in the methods of over-voltage and over-current protection that it performs. A further capability of the arrangement is that it resets itself after the fault condition has ended. This feature is particularly useful in the case of fault conditions of short duration.

Abstract: A telephone line interface circuit with d.c. amplifiers coupled to tip and ring paths is protected against transient voltages by a crowbar-type protection device coupled via a diode bridge to the tip and ring paths, positive and negative terminals of the diode bridge being connected respectively to ground and via a diode to a negative supply voltage line for the amplifiers. The diode prevents discharge of a capacitor, coupled between the negative supply voltage line and ground, through the protection device when it conducts. A locked up state, in which the amplifiers maintain holding current to the protection device after a transient voltage, is avoided by further diodes coupled from the negative terminal of the diode bridge to inputs of the amplifters, or by controlling a current limiter to interrupt current to the capacitor when the diode is reverse biased, so that the capacitor discharges. The current limiter includes a resistance and inductance in series for sensing current, whereby initial charging current for the capacitor is reduced on closing of relay contacts in series with the current limiter, and relay contact deterioration is avoided.
