Abstract: A digital subscriber line (DSL) circuit is disclosed and includes at least one transformer exciting network (TEN) adapted to supply a low-impedance path to ground in response to an excitation current. The excitation current has a non-DSL frequency, and the low-impedance path to ground allows the excitation current to flow through a DSL induction neutralizing transformer (INT). The DSL INT is electrically coupled to the at least one TEN. The DSL INT is adapted to add longitudinal inductance to a telecommunication line in response to the excitation current, wherein the longitudinal inductance suppresses induced harmonic currents.

Abstract: A digital subscriber line (DSL) induction-neutralizing transformer (INT) (28) for use in a DSL INT network (10) is provided. The DSL INT (28) includes a core (72) and a coil (74) that is electrically coupled to and wound around the core (72). The coil (74) includes approximately 100-200 feet of approximately 24-gauge wire. The core (72) and coil (74) add longitudinal inductance to a telecommunication line and reduce induced voltage levels at a non-digital subscriber line frequency on the telecommunication line. The DSL INT network (10), containing at least one DSL INT (28), and a method of routing DSL communication signals within the DSL INT network (10), are also provided.

Abstract: A device and method for imparting movement to a selected line are disclosed. A device incorporating teachings of the present invention may include a motion arm extending through an opening in the housing of the device. The arm may be coupled to a connection clip that can grip a selected line. The selected line may include, for example, twisted pair, coaxial cable, optical cable, shielded high-gauge wire, etc. In some embodiments, the arm of the device is coupled to a motion generator that imparts movement to the motion arm in at least one direction. In operation, the imparted movement may be conveyed through the motion arm and the connection clip to the selected wire.

Abstract: An integrated system and method is provided for processing a service request for installation, maintenance or repair of a local loop maintained by a telecommunications company and providing locally switched service to a customer premise.
