Abstract: A pre-loaded fiber raceway system for deploying optical fiber networks comprising an elongated substantially rigid base member having a back wall that is attachable to an interior wall structure of a building and a pre-loaded fiber flexible raceway tubing that is selectively routed and spliced into the base member. The length of the base member is interrupted at selected fiber drop points along the interior wall structure where the raceway tubing is unsupported by the base member. The raceway tubing has a split seam extending longitudinally along its length to permit the raceway tubing to be spread open along the split seam at the selected drop points for deploying one or more fibers from the raceway tubing at the selected drop points.

Abstract: Container cover/door with high security locking system comprises a metal cover/door having a first through opening surrounded by a first metal sleeve or collar extending inwardly from the outer surface of the cover/door. Fixedly attached to the inner surface of the cover/door is a metal bracket having a second through opening surrounded by a second metal sleeve or collar that extends outwardly within the first collar. The locking system comprises a locking mechanism including a spring loaded latch contained within a housing mounted to an inner surface of the metal bracket, and a security pin having a pin head that is encased within the second collar with a close tolerance therebetween, and a pin shaft of a smaller diameter than the pin head that extends inwardly from the pin head through an opening in the locking mechanism.

Abstract: Exterior raceway system includes one or more elongated base members and associated cover members for concealing and protecting one or more cables against the weather when mounted on an exterior wall structure of a building. The cover members are removably attachable to the base members to facilitate mounting of the base members to the exterior wall structure and the attachment of one or more cables to the base member prior to attaching the cover members to the respective base members.

Abstract: A cable molding primarily intended to be installed on a wall structure of a common hallway of a multiple dwelling unit below pre-existing molding, and an overlay molding attachable to the cable molding to conceal both the cable molding and the pre-existing molding. The overlay molding includes a panel member having upper and lower edges and a flange extending rearwardly from the panel member intermediate the upper and lower edges. The flange defines with a lower portion of the panel member a lower channel shaped for attachment to the cable member, and defines with an upper portion of the panel member an upper channel for receiving pre-existing molding.

Abstract: Slack cable storage box includes a base and a cover removably attachable to the base to provide an enclosure for a slack cable storage spool that may be part of the cover or removably attached to the base. The outer end face of the cover may be recessed for receipt of one or more interchangeable decorative faceplates.

Abstract: A drop cable wall entry guide assembly includes a base having a generally arch shaped track for maintaining a minimum bend radius in a cable extending along a wall structure and at least part way around the track for entry of the cable into a hole in the wall structure at substantially 90° relative to the wall structure without kinking. A cover closely surrounds the track except for a cable entry portion of the track which is accessible through an opening in an upstream end portion of the cover.

Abstract: Slack cable storage box includes at least one slack cable storage spool that is mountable at different heights within the box. Alternatively at least two such spools may be mounted in axial alignment with one on top of the other within the box depending on the particular need and the desired amount of slack cable to be stored within the box.

Abstract: Slack cable storage box includes a base and a cover removably attachable to the base to provide an enclosure for a slack cable storage spool that may be part of the cover or removably attached to the base. The outer end face of the cover may be recessed for receipt of one or more interchangeable decorative faceplates.

Abstract: A cable molding primarily intended to be installed on a wall structure of a common hallway of a multiple dwelling unit below pre-existing molding, and an overlay molding attachable to the cable molding to conceal both the cable molding and the pre-existing molding. The overlay molding includes a panel molding having upper and lower edges and a flange extending rearwardly from the panel member intermediate the upper and lower edges. The flange defines with a lower portion of the panel member a lower channel shaped to provide a snap fit onto the cable member, and defines with an upper portion of the panel member an upper channel that receives the pre-existing molding.

Abstract: Communication cable clip has an anchor portion for insertion between clapboards and a bottom portion which protrudes outwardly to provide structure having openings for ties for horizontal and vertical runs of cable.

Abstract: A processor unit for a multipoint audio-video conferencing system, wherein the processor unit includes a host processor for controlling operation of the audio-video conferencing system. Controlling operation includes controlling the performance of a plurality of functions associated with servicing each of a plurality of communications connections, each of the connections being between a conferee terminal and the audio-video conferencing system. The processor unit also includes a plurality of digital signal processors, in communication with each other over a first bus and in communication with and controlled by the host processor over a second bus. Each digital signal processor includes an associated configuration element for adaptively configuring a selected digital signal processor to perform processing required by a selected one of the functions associated with servicing a selected one of the communications connections.

Abstract: A clamping apparatus is positioned adjacent the interior wall of a sealed compartment. The wall has an opening providing an entryway for a fiber optic cable to the interior of the compartment. The clamping apparatus applies compression forces to an annular cylindrical body of a flexibly resilient and deformable grommet supported in line with the opening to seal the opening. The grommet has a passageway for the cable. The clamping apparatus, which essentially surrounds and conforms to the annular body of the grommet, is operable to compress the grommet radially around the cable and to axially urge the end face against the wall of the opening. A clamp member having clamping surfaces for compressing two side by side grommets in line with two side by side cable openings in the wall is disclosed. A headed rod extending at an angle to the wall with the cable openings therein supports the clamp member for angled movement to effect the compressive radial and axial forces.

Abstract: An improved system for connecting and processing a plurality of phone user in a teleconference on a common digital bus. The apparatus includes a plurality of digital processing units (DSPs) associated with selective phone lines and in communication with each other. Each DSP determines an activity status for each associated phone line and transmits that status to the other DSPs, The DSPs create and update respective identical "talk-lists" which reflect the active conferees whose voice data is currently being output on the phone channels. The system thus provides scaleable teleconferencing in a real-time configuration without switching between the various signals on the common bus such that each incoming caller or even a plurality of conferences has equal priority.

Abstract: An aerial storage device for storing an extra length of fiber optic cable as a loop in a transmission line in which the storage device has an arcuate end providing the return or turn-around arc of the loop and a planar deck, the outer periphery thereof defining the loop for the cable and being joined with the top of an inner sidewall of a U-shaped channel for receiving and storing a planar loop of fiber optic cable with the sidewalls of the channel being perpendicular to the plane of the deck and extending to one side thereof. The device is a one piece molded plastic device of plastic and has openings in the channel bottom and deck for tying cable to the device and reducing wind sway. The channel bottom and inner side wall extend around end of the device where the cable portions enter and exit the loop to provide a shelf for supporting the cable portions and a smooth nose surface for providing a smooth separation therebetween.
