Abstract:
The present invention relates to power input housings and assemblies for power distribution panels. The power input assemblies provide separate cavities with a centerwall for the power input cables to be led into and a cover closing the cavities. The cavities allow power cables to enter through either a top open end or a bottom open end and the cover is adapted to close the other open en when installed. Alternatively, the housing can be oriented with the open ends of the cavities to the sides, permitting cables to enter through either side and the cover closing the other side.
Abstract:
A jack module sized to occupy only a portion of a telecommunications chassis. The jack module includes a front jack mount, a plurality of jacks and a rear connector mount. The rear connector mount supports a plurality of connectors. The connectors include housings defining ports for receiving plugs. In certain embodiments, the connectors can include RJ-45 connectors.
Abstract:
The present invention refers to housing electronic equipment in an enclosure (1) comprising at least a roof element, two side wall elements (2-7) and two end wall elements (8, 9). At least one of the side wall elements (2-7) comprise a locking device (15) for fastening the side wall element (2-7) to an end wall element (8, 9). The present invention also refers to a method for providing an enclosure for electronic equipment in a space inside an existing building and to a housing for enclosing electronic equipment. The modular structure may be used to house a radio or mobile telephone system base station as well as other electronic equipment.
Abstract:
A splitter card including a circuit board on which line, data and voice connectors are mounted. The connectors include contacts electrically connected to termination posts that extend through the circuit board such that ends of the termination posts are exposed. A plurality of splitters are connected to the circuit board for splitting composite signals into voice and data signals. The circuit board includes conductive paths for directing composite signals from the line connector to the splitters, for directing voice signals from the splitters to the voice connectors, and for directing data signals from the splitters to the data connectors. Dielectric insulator members are connected to the circuit board to cover the exposed ends of the termination posts.
Abstract:
A telecommunications termination cabinet includes first and second connector bulkheads, the first bulkhead located in forward position relative to the second bulkhead. The first bulkhead is pivotally mounted to the cabinet. A splice cabinet is positioned below the termination cabinet.
Abstract:
A test box including a housing defining a front plane and a back plane. A plurality of jacks are positioned adjacent the front plane. The jacks define a plurality of rows of ports. Each row of ports includes at least 24 ports. The jacks also include electrical contacts corresponding to each of the ports. The testing box also includes a plurality of pairs of electrical connectors positioned adjacent the back plane. Each pair of electrical connectors includes an input connector for inputting signals into the test box and an output connector for outputting signals from the test box. The test box further includes a plurality of circuit boards positioned within the housing. The circuit boards include tracings for conveying signals from the input connectors to the jacks and for returning the signals from the jacks back to the output connectors.
Abstract:
Communication distribution equipment, and more specifically to methods and apparatus for supporting a multiplicity of densely arranged or packed electrical shielded communication panels, each of which has a ground or conductive sheet covering the back side of the panel to provide back side shielding to the circuitry on that same panel as well as front side shielding to an adjacent panel.
Abstract:
An enclosure for housing cable and associated equipment comprises a frame structure (22) and a plurality of panels (64, 66, 72, 74), the frame structure includes lower supporting means (24, 25) and an upper frame structure (26), the lower supporting means (24, 25) being arranged as a cantilever supported at its rear end, at least some of the panels being detachably mounted on the frame structure (22). One important advantage of the inventive enclosure is that of reduced deflection of the support members due to the weight of the cabling equipment which the enclosure holds.
Abstract:
The invention concerns a distributed communications system. In particular it concerns a modular system which includes one or more exchange units for installation in a rack at a telephone exchange. Each exchange unit has an exchange line interface, one or more optical fibre bearer cards and one or more service cards to support services to one or more remote units. The system also includes one or more remote units. Each remote unit is enclosed in a sealed housing for installation in a pit or manhole, and has an optical bearer card and remote service cards to provide customer services. The exchange unit is connected to a series of the remote units by a series of optical fibre links which extend between an optical fibre bearer card in each unit. The service cards associated with each optical fibre bearer card in the exchange unit are matched to the service cards of the remote units which are connected in the series to that optical fibre bearer card in the exchange unit.
Abstract:
A digital button telephone system which is connected to an analog public network (NW) having a function of transmitting a calling signal including the identification information of the caller through a subscriber line (CO line), incorporates a plurality of extensions to which digital button telephone sets (DKT) (2) or standard telephone sets (STT) (4) are respectively connected as extension terminals, and has a function of exchangingly connecting the subscriber's line to an extension or an extension to another extension. The system comprises terminal storing means in which the information representing the relationship between the caller and the extension terminal (2, 4) is stored in advance. When a calling signal arrives from the network (NW), the caller identification information (caller ID) included in the calling signal is detected by a caller identification information interface unit (RCIU) (12), the extension terminal to be called is determined based on the detected caller ID and the information stored in the storing means by a control unit (RCTU) (16), and the extension terminal is called through a digital telephone set interface unit (RDKU) (13) or standard telephone set interface unit (RSTU) (15).
