A network interface device includes an enclosure that houses active electronics for accommodating twisted-pair telephone wires and coaxial cable. The housing has a base that connects to a building wall. A shield locates within the housing, the shield having a platform and a perimeter wall that extends around the platform. A printed circuit board mounts within the shield between the base and the platform. The shield is hinged to the base so that it may be readily removed with the printed circuit board if repair is needed. A subscriber bridge module mounts on the platform. The subscriber bridge module has subscriber line termination points on one side that electrically connect with the subscriber lines. The subscriber bridge module also has telephone jacks electrically connected between the subscriber termination points and the provider line. This provides a demarcation between the subscriber lines and the provider line. An inner cover encloses a provider line port, any voltage protecting devices mounted on the platform, and power terminals on the subscriber bridge module.
