  • Publication number: 20020044646
    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.

  • Patent number: 6137866
    Abstract: An apparatus and method for mounting an xDSL signal splitter that is readily interconnected with existing indoor premises telephone wiring to provide separate access to voice and data signals by the subscriber. The apparatus comprises three pairs of terminations for connection of combined signal wiring, first signal wiring and second signal wiring. A first splitter circuit is mounted in the housing and electrically connected between the first pair of terminations and the second pair of terminations. A first signal jack extends through the exposed surface of the housing and is connected to receive only the first signal. In an alternative embodiment, the third pair of terminations is electrically connected to a branch point between the first pair of terminations and the first splitter circuit. In another alternative embodiment, a second splitter circuit is mounted in the housing and electrically connected between the branch point and the third pair of terminations.

  • Patent number: 6026160
    Abstract: The present invention provides a splitter module with an xDSL splitter circuit that is removably installable in a network interface device (NID) and interconnectable with a POTS module in the NID to split the POTS and xDSL signal onto separate inside wire pairs terminated in the NID. The splitter module has a jack and a plug. The plug from the POTS module is inserted in the jack on the splitter module and the plug on the splitter module is then inserted into the jack on the POTS module. This exchange of plugs and jacks place a splitter circuit between the outside plant wiring and the pairs of inside wiring.
