Abstract: Apparatus providing at least one subscriber with subscriber service signals, telephone line signals and/or broadband signals, from one of at least two providers of such signals, including a connector for terminating at least one subscriber premises line, connectors for terminating incoming service lines from at least two providers of subscriber service signals and for permitting either provider of subscriber service signals to connect its incoming service line to the subscriber premises line and for permitting either provider to disconnect from the subscriber premises line the incoming service line of the other provider previously connected to the subscriber premises line and thereafter connect its incoming service line to the subscriber premises line.

Abstract: Optical fiber closure including a pair of mating surfaces one of which is provided with a groove having a first volume and a deformable sealing member mounted in and extending outwardly from the groove with the groove having a volume larger than the volume of the sealing member; upon the mating surfaces being forced together, the sealing member is compressed and deforms within the groove and provides a substantially fluid-tight seal between the surfaces. The closure may include a plurality of cable clamps provided with outwardly extending deformable sealing members which are received in grooves having a larger volume than the volume of the sealing members whereby upon the cable clamps being forced into engagement with optical fiber cables entering or exiting the closure the sealing members are received in the grooves and compressed and deformed within the grooves to provide a fluid-tight seal between the cable clamps and optical fiber cables entering or exiting the closure.
