A subscriber network interface device for multiple subscriber pairs at a common location housed internally in a compact connector block easily mounted upon a wall by screws or a known mounting bracket to eliminate the need for installation of separate one or two line network interface devices. Incoming line connection is made using quick clip elements. Outgoing line connection is made via a female connector which is used to communicate with other quick clips. The circuits are latched in actuated state by the application of a 130 volt direct current applied to the tip or ring side of the line.
