Abstract: Closure for containing splices between optical fibers including a frame providing a plurality of optical fiber cable entry/exit ports, splice tray stacker mounted to the frame and for stacking a plurality of splice trays, and an outer cover for being fastened closed around the frame and the splice tray stacker to provide mechanical and environmental protection thereto.

Abstract: A connector unit (21) for automatically terminating a digital data services (DDS) line whenever a mating modular plug (30) is not inserted into the connector. The connector utilizes a switchable DDS jack (25) that mates with the modular plug (30) for connecting a data-transmit line and a data-receive line of a DDS network (41) to a customer's equipment (45). The connector unit has a maintenance termination circuit (40) with terminating impedances (r, r1, C and C1) and diodes (D and D1). When the plug and jack are not engaged, the maintenance termination circuit is connected to the data-transmit and data-receive lines via the normally closed jack contacts (33 and 34). As the plug and jack are engaged, the plug abuts against and, as movement continues, increasingly opens the jack contacts, causing the maintenance termination circuit to be disconnected from the customer's equipment and to be connected to the DDS network.

Abstract: Apparatus for storing and organizing spliced optical fibers into one of a plurality of in-line and butt splicing configurations and for imparting sufficiently large curvature to the curved portions of such optical fibers present during storing and organizing to prevent damage to the optical fibers, and a cover for such optical fibers upon being stored and organized.

Abstract: Combination apparatus for connecting one or more incoming telephone company lines to one or more telephone subscriber premises lines and for connecting incoming cable television signals to a television set, and a cable television module for being mounted to telephone network interface apparatus and for connecting incoming cable television signals to a television set.

Abstract: Apparatus for storing and organizing spliced optical fibers into one of a plurality of in-line and butt splicing configurations and for imparting sufficiently large curvature to the curved portions of such optical fibers present during storing and organizing to prevent damage to the optical fibers, and a cover for such optical fibers upon being stored and organized.

Abstract: Splice housing apparatus are provided on its interior with spacers or spacing members for engaging the splice or splices contained by the apparatus and for maintaining the splice or splices substantially out of engagement with the interior of the apparatus and generally suspended therein whereby a body of material for preventing water damage to the splice or splices can substantially surround the splice or splices and prevent water damage thereto.

Abstract: A telephone jack includes a first pair of contact wires for connection to a subscriber premises line and a second pair of contact wires for connection to an incoming telephone company line, a pair of bridging members are mounted for insertion in the jack and into engagement with the first and second pairs of contact wires to interconnect the subscriber premises line and the incoming telephone company line and are for being withdrawn from the jack and from engagement with the first and second pairs of contact wires to disconnect the subscriber premises line from the incoming telephone company line to provide a demarcation point therebetween.

Abstract: A frame provided with a plurality of inwardly extending arcuate members for having conductors coiled therearound and for storing the conductors in a generally circular shape. The frame may be mounted intermediate a faceplate and a conductor box, and upon such intermediate mounting the frame may include passageways for receiving screws which mount the faceplate and the frame to the box.

Abstract: An optical fiber interconnect cabinet for interconnecting incoming telephone company optical fibers with outgoing customer optical fibers either by adapters mounted on an internal bulkhead or by adapters mounted on an external cabinet wall; a pair of stepped, multi-level radiuses are mounted internally of cabinet and provide two storage levels for storing the optical fibers.

Abstract: A timing circuit and apparatus that utilizes this circuit. The apparatus is particularly suited for use with a telephone network interface, for substantially preventing a third party who gains access to the interface from placing an unauthorized telephone call through a network connection obtained through a jack, typically modular, located in a customer portion of the interface. Specifically, this apparatus is connected in series within the telephone company side of the interface to illustratively a ring lead of an incoming subscriber loop. In operation, the apparatus provides network access, by supplying loop current, on a timed periodic (repetitive) basis to a telephone (or other equipment through which a telephone call can be placed) plugged into the jack located within the network interface. Access is provided for a period of time that is sufficient to test loop current but is insufficient to allow the network to complete a call dialed from that telephone over this loop.

Abstract: Individual security subscriber line module including a generally rectangular, hollow box-like structure including a top, bottom, opposed sides and opposed first and second ends, such structure providing an internal space for receiving an individual circuit; a pair of subscriber wiring terminals mounted on the top for connection to a subscriber line, a plug connected to the pair of subscriber wiring terminals by first electrical conductors; a jack mounted on the top and provided with second electrical conductors for connecting the jack to the incoming telephone company line, the jack for having the plug plugged therein to interconnect the pair of subscriber wiring terminals and thereby the subscriber line to the incoming telephone company line and the plug for being unplugged from the jack to provide a demarcation point between the subscriber line and incoming telephone company line, and upon the plug being unplugged from the jack the jack for receiving the plug of an operating telephone to facilitate determin

Abstract: Telephone network interface apparatus including a base and a wall circumscribing the base and extending outwardly therefrom, the base and wall cooperatively providing an open compartment having a telephone company compartment portion and a subscriber compartment portion; the telephone company compartment portion is for having a plurality of pairs of telephone company terminals mounted therein for connection to a plurality of incoming telephone company lines and the subscriber compartment portion for having a plurality of subscriber terminals mounted therein for connection to a plurality of subscriber premises lines. A telephone company cover is included and is mounted pivotally to a portion of the wall and is for being closed and fastened over the telephone company compartment portion; first fastening means are included for fastening the telephone company cover closed over the telephone company compartment portion.
