Abstract: A telecommunications electric circuit having a low return loss and low crosstalk is adapted for use with unshielded twisted pairs of connecting wires. The circuit includes a pair of elongated circuit conductors parallel to each other over a substantial portion of their respective lengths. Each circuit conductor being a trace having a uniform width over a substantial portion of the length of the trace. Each circuit conductor trace having a width equal to the width of the other trace of the pair. Each of the circuit conductor traces has a uniform thickness. The circuit conductor traces are spaced apart a uniform distance which distance is determined from the center of each trace to the center of the other trace. The uniform distance being no greater than twice the width of one of said traces. A compensation trace is spaced from, parallel to and aligned with a portion of each of the respective circuit conductors.

Abstract: A vertical organizer is mounted between a pair of telecommunication relay racks. Each rack has a backside which is in substantially the same plane as the backside of the other rack. Each rack has an upright defining a side positioned adjacent to and spaced from an upright of the other rack which upright of the other rack defines an adjacent side of the other rack. The vertical organizer includes a vertical trough having opposed sides fixed to adjacent uprights. The trough has a open side on the same side as the backside of the relay racks to provide a channel for positioning a plurality of telecommunication cables between the racks.

Abstract: A telecommunication relay rack for mounting on a floor includes a pair of uprights. A horizontal member is secured to the top of the uprights and a base is secured to the bottom of the uprights. The base includes a pair of identical half bases. Each of the half bases is a single unitary member including a squaring plate. A pair of feet is formed integral with opposed ends of each of the squaring feet. Each foot has a toe pad positioned below the bottom of the respective upright. Each upright has a pair of vertically spaced aligning apertures adjacent to the respective bottom on opposite sides of the upright. Each squaring plate has a pair of vertically spaced base apertures aligned with the respective aligning apertures. A base fastener in the base aperture and aligning aperture secures the respective squaring plate to a respective side of each upright to hold the uprights in a substantially vertical attitude parallel to each other. The toe pads are mounted on a floor whereupon the relay rack is supported.

Abstract: A telecommunications wall rack is particularly adapted for supporting a plurality of telecommunications panels. The wall rack includes a support frame which is adapted for mounting on a substantially vertical surface. The wall rack includes a mounting frame adapted for supporting a plurality of telecommunications panels. A pair of aligned hinges pivotally connects the mounting frame to the support frame. Each of the hinges has an axis of pivoting substantially aligned with the axis of pivoting of the other hinge of the pair. Each of the hinges has a threaded hinge pin mounted on the support frame. The mounting frame is threadedly connected to each hinge pin for pivoting on the hinge pins. A locking apparatus releasably connects the mounting frame to the support frame to allow selective pivoting of the mounting frame on the threaded hinge pins relative to the support frame to provide access to both sides of the mounting frame.

Abstract: An improved construction for a quick connect frame used for interconnecting a plurality of wires, which wires are part of a communication system, is the subject matter of this invention. The quick connect frame includes a pair of interconnected uprights. The uprights are held in a substantially vertical attitude. A vertical cable path is positioned adjacent to one of the uprights. A plurality of block modules is mounted on one side of the uprights. The one side of the uprights defines a substantially vertical upright plane. A set of terminating blocks is mounted on each of the block modules. Each set of terminating blocks on each block module is in one substantially vertical block plane, which block plane is spaced from and substantially parallel to the vertical upright plane. A horizontal jumper path is positioned adjacent to each set of terminating blocks.

Abstract: A commnication system patch panel is the subject matter of the present disclosure. The present patch panel provides a convenient device for selectively connecting a wire from one plurality of wires to a selected wire of another plurality of wires. The patch panel includes a front side having an access opening on its front side. The patch panel includes a mounting plate which is adapted for being mounted on a vertical surface. A plurality of connector blocks is mounted on one side of the mounting plate. A portion of the connector blocks is adapted to be connected to wires which are connected to a communication network. Each of the connector blocks of the remainder of the connector blocks is adapted to be connected to wires which are connected to terminals. Each of the blocks adapted to be connected to a wire connected to a communication network is connected to a respective network jack. The network jacks are mounted on one side of the mounting plate at the front of the patch panel.

Abstract: In a building cable system, a building cable has a portion for carrying electronic data signals for networked digital computers and a second portion for carrying electronic telephonic signals for telephone instruments. The system includes a relay rack with a data cross connect panel connected to the data signal carrying portion of the building cable for carrying data signals. A wire terminal panel is mounted on the relay rack. The wire terminal panel includes a pair of supports fixed to the relay rack. A pivot pin is mounted on each of the supports. A telephone block bulkhead is pivotally mounted on the pivot pins to pivot relative to the supports and the relay rack. A bulkhead lock releasably connects the telephone block bulkhead to one of the supports to hold the telephone block bulkhead in a selected position. The telephone block bulkhead includes a wall.

Abstract: An improved construction for a quick connect frame is the subject matter of this invention. The instant quick connect frame is used for interconnecting a plurality of wires which wires are part of a communication system. The frame has a pair of uprights and a bridge connecting the uprights. Feet are connected to the bottom of the uprights to hold the uprights in a vertical attitude. A mounting bracket is secured to the uprights to support a block module. A mounting strip is connected to the mounting bracket. The mounting strip includes a support bar and a stiffening bar. The stiffening bar is formed integral with the support bar and is substantially perpendicular to the support bar. An elongated recess is formed in the support bar and the stiffening bar at the junction of the support and stiffener bars. A plurality of spacers is secured to the support bar. Each of the spacers includes an elongated base secured to the support bar and a bar of posts. A mounting bar interconnects the posts.
