ABSTRACT:
A housing for a distributed filter removably mounts to a wall plate between the wall plate and a wall-mount telephone without the use of a tool. The housing includes a base and a cover attached to the base that together define a cavity. A filter circuit for filtering voice signals is disposed within the cavity. A phone jack and at least one auxiliary jack are also disposed in the cavity and accessible through the cover. In one embodiment, viewing windows are formed through the cover to permit an installer to view the mounting studs on the wall plate during installation. A slide lock is also provided to secure the housing to the wall plate. In another embodiment, a push-button lock is provided to secure the housing to the wall plate. The push-button is forced outwardly during installation when a mounting stud engages a slot formed in the base and is subsequently depressed to secure the housing to the wall plate.
