Abstract: A device for providing transient voltage suppression on a Power over Ethernet system is provided. The device includes a transient voltage suppression module. The transient voltage suppression module includes a circuit module, which includes a circuit board and input and output connectors. One or more transient voltage suppression modules may be mounted to a frame to form a transient voltage suppression patch panel, which, in turn, may be mounted to a rack for use in a telecommunications room. The circuit board combines a frequency-variable impedance connected between conductors in a pair and a voltage-variable impedance connected to the frequency-variable impedance, where the voltage-variable impedance is also connected to a chassis and/or an electrical ground.

Abstract: A jack is provided that has compensation and crosstalk zones. At least one of the zones employs a lattice network that couples conductors in the zone to reduce the net crosstalk in the plug/jack system. The lattice network has a frequency response slope that is different from the frequency response slope of a first-order coupling or of a series LC circuit coupling. A variety of lattice networks are provided.

Abstract: A tone burst generator where a continuous tone voltage is applied across two series-connected semiconductor switches each having an ON state and an OFF state. A first control circuit controls the state of the first switch and the variable impedance in an intermediate region between its ON and OFF states to cause gradual, well-defined OFF/ON and ON/OFF transitions of the first switch. As a result of these first switch transitions, a voltage tone burst is generated that has precisely defined edges to eliminate clicking noise. The continuous tone voltage is of only one polarity--it has a non-zero DC component and an AC component having a peak-to-peak variation less the twice the magnitude of the non-zero DC component. A second control circuit controls the state of the second switch and the variable impedance in an intermediate region between its ON and OFF states to cause well defined ON/OFF and OFF/ON transitions of the second switch.
