Abstract: A telephone network interface device for a building entrance terminal includes a cabinet for housing one or more interface modules. Each interface module is hingedly connected to a rail on the bottom of the cabinet such that the module can be rotated upwardly or downwardly and secured in the cabinet with a special screw. Each interface module has a front face and a back face. The equipment mounted on the front face of the panel constitutes the subscriber equipment and the equipment mounted on the back face constitutes the service provider equipment. When the interface module is rotated upwardly, a walled housing on the back face which contains service provider equipment presses against a foam pad within the cabinet, thus providing an environmental seal to equipment mounted within the housing. When the interface module is rotated upwardly and secured, the front face of the panel with the subscriber equipment is accessible to anyone who opens the cabinet, including the subscriber.
