Abstract:
An apparatus with a line card having a front panel including at least one input/output port. The apparatus further includes a line card interface assembly. The line card interface assembly includes at least one of an input and output line support, at least one guide vane cooperating with said line, and a front face providing an electrical coupling with said front panel sufficient to attenuate electromagnetic waves passing through the front panel.
Abstract:
A method and apparatus for upgrading in-service or legacy telecommunications cabinets that improves power, cooling, space and EMI capabilities, allowing the cabinet to house updated, telecommunications equipment. The upgrade modules include an extension collar that replaces legacy doors, allowing the attachment of replacement doors having integral heat exchanger units. The extension collar also has support for Electro-magnetic Interference (EMI) shielding gaskets so provide EMI shielding capable of meeting FCC mandated levels. Additional upgrade modules include a battery chamber attached beneath the base of legacy cabinet, cooled and vented by one or more of the heat exchanger doors, thereby providing longer battery life.
Abstract:
An xDSL modem assembly is provided. The assembly comprises a housing, a circuit board having xDSL electronics, and a multi-layer electromagnetic shield formed to receive the circuit board. The circuit board is positioned inside the multi-layer electromagnetic shield, and the multi-layer electromagnetic shield is positioned inside the housing.
Abstract:
The invention is a modular terminal block assembly. The modular terminal block assembly includes a base module in which communications company lines may be dressed and retained during the dressing operation. A connector module is provided for attachment over the base module and to engage the distribution lines retained in the base module with insulation displacement connectors (IDC) which are retained in the connector module. A protection module is provided for engagement with an opposite side of the base module so that protection can be provided on the lines without interfering with the connection termination of customer service line on the connector module. The modular terminal block assembly provides structures which allow the assembled modular terminal block to be retained on a standard U-shaped mounting frame or for attachment to a rod frame system. The protection module maintains protection on the lines while the terminal block assembly is in contact with the U-shaped frame and rod frame system. A half-tap assembly may be attached to the modular terminal block, independent of the service line assembly for the addition of a line to the terminal block. An environmental protectant is retained in the modular terminal block to protect the conductive connections retained therein from detrimental environmental effects.
Abstract:
A voltage protector and grounding bar arrangement is provided for use with a telephone terminal block having at least two rows of terminals which are spaced apart from each other so as to define an elongated channel therebetween. A housing has incorporated therein a voltage suppressor, terminal contacts for mating with the terminals of the terminal block, and a ground contact for mating with a grounding bar disposed within the channel of the terminal block. Plug-in carrier devices are adapted to be mounted in a plug-in manner upon the housing, and the carrier devices may comprise fuse-type current limiting devices, positive-temperature-coefficient (PTC) current limiting devices, or bridging clips. The housing may accommodate a single plug-in carrier device, or dual plug-in carrier devices whereby protection is afforded to the circuit-to-be-protected in a multitude of directions.
Abstract:
An overvoltage protection module can be fitted to a telecommunications module having telecommunications contacts, to which telecommunications lines are connectable, and has at least two overvoltage protectors, at least one ground contact, and at least two pairs of protection module contacts for contacting the telecommunications contacts at contact points, so that at least two telecommunications lines are protectable, wherein the contact points are located on at least two different levels, and both contacts of each pair of protection module contacts are connected to the same overvoltage protector.

Abstract:
A cross-connect module is disclosed herein. The cross-connect module includes a housing having a front end and a rear end. The rear end includes a printed circuit board mounted to the module. First and second switching jacks positioned adjacent the front end of the housing. A DIN type rear connector is mechanically mounted to the printed circuit board. The switching jacks are routed to the DIN type rear connector via coaxial cables that are terminated to the connector. The printed circuit board is used to route a tracer lamp circuit of the module to power and ground through the DIN type rear connector.
Abstract:
An enclosure apparatus comprises a single receptacle comprising a patch member connected to electrical equipment in a remote location and at least one communication device. The communication device may comprise a microprocessor for processing data received from the electrical equipment in the remote location. The enclosure apparatus is often used in connection with building automation equipment.
Abstract:
A insulation displacement connector (IDC) patch panel includes a circuit (PC) board with interdigitated capacitance for balancing out inherent capacitance found within IDCs of the panel. Unwanted cross-talk signals are reduced as a consequence.
