Abstract

See full text

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.
