To eliminate interference with digital broadband service created by bridge tapped connections in local loop distribution cables, a switch is associated with each broadband customer drop cable connection in the terminals along the length of each distribution cable. In one position, a switch connects the upstream portion of a metallic circuit to the downstream portion of the circuit. The switch also may connect the metallic circuit to an associated one of the connectors. This bridge tapped connection enables use of the metallic circuit for a subscriber drop connection through a downstream terminal. In a second position, a switch connects the upstream portion of the metallic circuit only to the connector associated with the switch in the local terminal. A drop cable for broadband service runs from the connector in the local terminal to a nearby subscriber premises. In position, the wiring of the metallic circuit downstream of this terminal is disconnected, eliminating interference with broadband service transport over the circuit to the subscriber premises.
