Abstract:
Frame injection apparatus for injecting frames from a host device into a switched Ethernet network comprises a frame memory operable to receive and store one host frame at a time and to inject the frame onto the Ethernet switched network between network frames and to buffer network frames received during the time that the host frame is being injected onto the network.
Abstract:
An upgradeable patch panel assembly and associated method of upgrading a patch panel assembly. The upgradeable patch panel assembly including a panel base having an aperture sized to receive a scanner interface cable. The method including removing a first cover from the panel base, inserting a scanner interface cable through the existing aperture in the panel base, and attached an upgraded cover to the panel base. Upgrading the patch panel assembly is completed while the assembly remains mounted to a frame and without disconnecting rear cable connections. The upgraded patch panel assembly provides jack-occupancy monitoring capabilities.
Abstract:
A telecommunications system includes a chassis having a front side and a rear side and a plurality of jacks mounted to the chassis. Each jack includes an IN port, an OUT port and a MONITOR port. A cross-connect panel including an array of cross-connect connection locations is accessible from the front side of the chassis. An optical multiplexer housed within the chassis is electrically connected to the jacks by circuitry within the chassis. The multiplexer is configured to multiplex a plurality of IN electrical signals that are going away from the jacks toward a piece of telecommunications equipment to an IN optical signal and is configured to split an OUT optical signal that is going away from the piece of telecommunications equipment toward the jacks to a plurality of OUT electrical signals, wherein the IN electrical signals and the OUT electrical signals can be monitored by inserting plugs into the MONITOR ports of the jacks.
Abstract:
A cable management assembly, and method related thereto, including a panel having an interface portion. The interface portion having a plurality of discrete openings, including first and second shaped apertures. The assembly further including cable management devices having securing structure including a flexible tab and a locating element. The securing structure being configured to mount the cable management devices at selected vertical and horizontal locations on the panel. The cable management assembly being configured to mount between two adjacent telecommunication racks or to an end of a telecommunication rack.
Abstract:
A cable management system is provided including a mounting fixture for holding telecommunications equipment, and a ribcage cable support member along a vertical side of the mounting fixture. The ribcage cable support member includes a plurality of forwardly and rearwardly extending ribs. The ribs each include cable retention tabs. A plurality of spools are provided for cable storage on the ribcage cable support member. Holes through the ribcage cable support member allow access between the front and rear portions. An additional mounting fixture may be positioned on an opposite side of the ribcage cable support member to the first mounting fixture, and two columns of ribs are provided.
Abstract:
A cable manager is disclosed. The cable manager includes a backbone (22), a plurality of finger sections (26) connected to the backbone to form a vertical cable channel, and a first pair of horizontal rails (25) connected to the top end of the backbone and a second pair of horizontal rails connected to the bottom end of the backbone. The cable manager also includes a first cross brace (24) connected to the first pair of horizontal rails and a second cross brace connected to the second pair of horizontal rails, and a door (28) hingedly connected to the first and second cross braces. Each cross brace includes a mounting surface (36) having a plurality of guide surfaces (40) and an alignment aid (42) protruding from the mounting surface and extending beyond a horizontal axis extending between the guide surfaces. The door includes a pair of latches (46,48)connected to a hinge pin (44) through a pair of windows, and a spring (50) connected to the hinge pin and the pair of latches.
Abstract:
A modular shelf system (100) for use with an equipment support structure (20) to manage cables has opposed front and rear sides (100A,100B). The shelf system (100) includes a base member (110) adapted to be secured to the equipment support structure and first and second drawers mounted on the base member in side-by-side relation. Each of the first and second drawers (140,140A,140B) is adapted to receive at least one cable from the rear side of the shelf system. Each of the first and second drawers includes a front panel (160) located adjacent the front side of the shelf system and defines a cable port. Each of the first and second drawers is slidable between a first, stored position within the base member and an open position wherein the respective drawer is disposed forwardly of and at least partially withdrawn from the base member to provide access from the front side of the shelf system to a cable or cables introduced into the respective drawer from the rear side of the shelf system.
Abstract:
Mechanisms for mounting, opening, closing and releasing a door assembly relative to a mounting structure are provided. The mechanisms employ a first structure that defines at least one elongated guide channel and a latching subassembly that is adapted to be mounted with respect to the foregoing guide channel(s) and to rotate with respect thereto. Rotation of the latching assembly with respect to the guide channel(s) allows a latching region, e.g., a V shaped latching region, to move between a first position (wherein the latching region is adapted to receive a mounting structure) and a second position (wherein the latching region cannot receive a mounting structure). In the second position, the latching region (in combination with the guide channel) is structured to capture a mounting structure (e.g., a projection associated with a cable management system) therewithin. Methods for use of the door assembly and latching subassembly are provided, as well as particular utilities thereof, e.g., rack-mounting applications.
