Abstract: Systems and methods for live proximity-based media transfer are disclosed. For example, a secure network between a sharer device and a viewer device may be established when the devices are within a given geographic area of one another. An instance of an application running on each device may be utilized to authenticate a sharing session and then the sharer device may share media with the viewer device. The viewer device may have its functionality limited when in the viewer mode such that the viewer device may only view the shared media, zoom the view of the media, and/or exit the sharing session and/or application. The shared media is not saved to the viewer device and cannot be permanently manipulated by the viewer device.

Abstract: Heat dissipating electronic components and circuitry in a communication chassis are cooled by moving air at least through a midplane, between two groups of channels that are laterally oriented relative to one another. In an illustrative embodiment, channels of one group are oriented vertically while channels of another group are oriented horizontally. Each channel, regardless of whether it is vertical or horizontal, is defined by space in the chassis between adjacent circuit boards. Circuit boards on one side of the midplane are electrically connected to circuit boards on the other side of the midplane by orthogonal connectors on the midplane. The midplane additionally has openings that enable movement of air between vertically-oriented channels and horizontally-oriented channels. Circuit boards of the two orientations are cooled by increasing air pressure in vertically-oriented channels or by decreasing air pressure in horizontally-oriented channels or both, depending on the embodiment.

Abstract: A network element of a transport network has three fabrics housed within a single shelf of a telco rack, namely a packet fabric, an electrical fabric and an optical fabric. A stream of traffic including a plurality of lambdas is received at a trunk interface of such a shelf. The optical fabric in the shelf performs optical switching on the stream to replace a first lambda in the stream with a second lambda. The first lambda is converted within the shelf into an electrical signal. Also within the shelf, first frames are recovered from the electrical signal. The packet fabric in the shelf is used to perform packet switching on the first frames to generate a flow of second frames. The flow of second frames is transmitted at a client interface of the shelf.

Abstract: A shelf of communication equipment provides frontal illumination of a face plate of the shelf. Specifically, a shelf in a rack in a communication network includes a face plate and a bezel. The face plate has a first exterior surface that carries a legend. The bezel forms a second exterior surface extending in a predetermined direction transverse to the first exterior surface. For example, if the first exterior surface is vertical, the second exterior surface is horizontal and overhangs the first exterior surface. During operation, electromagnetic radiation generated by a source enclosed by the bezel exits through the second exterior surface and directly illuminates at least the legend, and optionally also illuminates a electronic device adjacent to the legend, such as an LED or a jack, if such a device is present on the first exterior surface.

Abstract: A network element of a transport network has three fabrics housed within a single shelf of a telco rack, namely a packet fabric, an electrical fabric and an optical fabric. The shelf also includes inter-fabric circuitry, to bridge between the fabrics, e.g. packet-electrical and/or electrical-optical and/or packet-optical. The inter-fabric circuitries switchably transmit packets across fabrics in intermediate nodes of the transport network. The single shelf of some embodiments has a wall (“midplane”) between a rear region that holds the three fabrics and a front region that holds inter-fabric circuitry, and external interfaces to optical trunks and/or packet services and/or optical tributaries.
