Abstract

An apparatus and method for mounting an xDSL signal splitter that is readily interconnected with existing indoor premises telephone wiring to provide separate access to voice and data signals by the subscriber. The apparatus comprises three pairs of terminations for connection of combined signal wiring, first signal wiring and second signal wiring. A first splitter circuit is mounted in the housing and electrically connected between the first pair of terminations and the second pair of terminations. A first signal jack extends through the exposed surface of the housing and is connected to receive only the first signal. In an alternative embodiment, the third pair of terminations is electrically connected to a branch point between the first pair of terminations and the first splitter circuit. In another alternative embodiment, a second splitter circuit is mounted in the housing and electrically connected between the branch point and the third pair of terminations. A second signal jack extends through the exposed surface of the housing and is connected to receive only the second signal.
