Abstract:
PROBLEM TO BE SOLVED: To provide a communication apparatus of plug-in mounting which can mount a highly heating component in a high density while assuring an EMI resistant capability and a cooling performance. SOLUTION: The communication apparatus comprises a shelf 4 made of a metal having a pair of side plates, a back wiring board 6 having a plurality of connectors and a solid ground pattern mounted on the back surface side of the shelf 4, and upper and lower guide plates mounted on the shelf having a plurality of guide rails and a plurality of vent holes. A first shielding board 16 having many openings is mounted on the upper guide plate, and a second shielding board having many openings is fixed to the lower side of the lower guide plate. Each plug-in unit includes a second connector mounted on a circuit board, a front surface structure fixed to the front surface side of the circuit board, and first conductive gasket provided over upper surface of the front surface structure, one side face and lower surface. A second conductive gasket is mounted on one of the side plate of the shelf. COPYRIGHT: (C)2004,JPO
Abstract:
An optical switch with a plurality of actuators includes a controller configured to control the operation of a plurality of channels, where each channel has at least one electrical driver and at least one actuator, by interleaving periods of voltage switching output with periods of no voltage switching output for one or more drivers whilst the output voltage is switching from one level to another level. Alternatively, an optical switch with a plurality of actuators comprises a controller configured to control the operation of a plurality of channels, where each channel has at least one electrical driver and at least one actuator, by switching the output voltage from one level to another level for at least one driver of a first channel whilst at least one oilier driver of at least one other channel is in a relatively high impedance mode.
Abstract:
Methods, systems, and devices are described for wired communication. A first distribution point uses sets of modems to communicate with a second distribution point over a crosstalk link to exchange information and coordinate the use of multiple sets of frequency bands. In some cases, the first distribution point may share a cable binder with the second distribution point and detect crosstalk on the subscriber lines in the cable binder. Based at least in part on the crosstalk detected by the first distribution point, the first and second distribution points may communicate over a crosstalk link between sets of lines in the binder. The distribution points may use one or more sets of predefined tones within the multiple sets of frequency bands to exchange messages, where the messages may include synchronization information, operating parameters, or control and data information.
Abstract:
The invention relates to a terminal block for data and telecommunications systems, comprising at least one insulating body. At least one connecting element (8), designed to house a grounding clip (9), is configured on the underside of said body. According to the invention, the grounding clip (9) has a first detent geometry for connecting to the connecting element (8) and a second detent geometry for connecting to a mounting frame. The connecting element (8) has a geometry that is independent of the mounting frame, the first detent geometry of the grounding clip (9) is adapted to the geometry of the connecting element (8) and the second detent geometry is adapted to the mounting frame.

Abstract:
The disclosure describes an active network interface device (NID) enclosure having a modular construction that provides flexibility to a vendor and permits independent access to technician-accessible connections and subscriber-accessible connections while promoting resistance to environmental and security threats. The active NID enclosure includes an electronics enclosure and an access enclosure. The electronics enclosure contains active electronic components for conversion of data carried on a network signal carrier into services for delivery to subscriber devices. The access enclosure includes two separate access compartments, having separate covers, for independent access to either network terminals or subscriber terminals.
