Abstract: The present invention controls delivery of television content to conserve network resources based on whether the television content is being viewed on a television monitor. A television gateway may monitor a viewer's interactions with the television gateway to determine whether the television content is being viewed at the associated television monitor, or detect whether the television monitor is on or off. Upon determining that the viewer is not viewing the television content, various actions can be taken to conserve network resources.

Abstract: The invention provides for a system, method, and device for using the existing copper loop plant of twisted pair wiring for data communication by using a plurality of pairs in a cable bundle of twisted pair for the downstream data direction simultaneously, as if the plurality of twisted pair in the cable bundle were a broadcast medium. Between an individual subscriber's access pair and the cable bundle, an aggregation device is used to combine all received signals from the plurality of twisted pairs in the cable bundle and to make the entire downstream bandwidth of the plurality of pairs available to the subscriber.

Abstract: A protection arrangement for a telephone subscriber line interface circuit is disclosed. The arrangement is particularly useful for protecting an electronic telephone set from over-voltage and over-current fault conditions. The arrangement provides a FET that operates in saturation mode to connect an office battery to the subscriber line under normal operation. The FET also provides isolation capabilities for protecting the line circuit from an over-current condition on the subscriber line. Over-voltage protection is provided by way of an isolation relay between the line circuit and the subscriber line. Both the FET and isolation relay are operated by a controller that uses timers in the methods of over-voltage and over-current protection that it performs. A further capability of the arrangement is that it resets itself after the fault condition has ended. This feature is particularly useful in the case of fault conditions of short duration.

Abstract: An improved electrical interconnection between a first circuit board and a second circuit board is provided. In one embodiment, the first circuit board has a substantially rigid circuit portion having a plurality of circuit layers, including a first signal layer, and a first interconnection portion, including the first signal layer, for mating with a second interconnection portion of the second circuit board. The first circuit board also includes a flexible portion, including the first signal layer, for connecting the substantially rigid circuit portion to the first interconnection portion. The flexible portion allows the first interconnection portion to be oriented substantially perpendicular to the substantially rigid circuit portion such that a mating of the first interconnection portion with the second interconnection portion results in a substantially orthogonal electrical interconnection arrangement between the first circuit board and the second circuit board.

Abstract: A technique for connecting signal tracks within a multi-layer substrate is disclosed. In one embodiment, the technique is realized by providing an opening in a substrate and fitting an inserted component into the opening. The inserted component comprises a dielectric block mounted to a lead frame. The lead frame is conductive such that a signal layer formed between the inserted component and the substrate connects signal tracks on multiple signal layers of the substrate.

Abstract: A wireless telephone system includes: a PBX connected by a wireline to at least one base station for communicating over a radio link with mobile telephones; a unit for transmitting and receiving audio and data signals over the wireline between the PBX and the base station; a unit for transmitting and receiving audio and data signals over the radio link between the base station and a mobile telephone; and in the base station a unit for separating incoming audio and data signals channels, a unit for combining outgoing audio and data signals for onward transmission thereof from the base station, and a unit for interpreting the data signals and either acting on the data signals if they are intended for the base station or otherwise passing the signals through the base station for onward transmission to the receiving unit.

Abstract: An apparatus for establishing communication between one or more digital radio channels and one or more digital wireline signals over the digital radio channels, comprising an r.f. unit for transmitting and receiving circuits, a digital interface unit connected to each wireline circuit, a unit for separating incoming signals into bearer channels and signaling information, and a unit for recombining the outgoing bearer channels and signaling information into the appropriate format for transmission over the outgoing medium.

Abstract: The present invention relates to a subscriber presence detector system comprised of a switching system for connecting calls to and from a plurality of lines, a person presence detector connected to a line, for providing an indication to the switching system that a person is adjacent or not adjacent the detector, and apparatus for routing calls to the line in the event an indication has been received by the switching system that a person is adjacent the line.

Abstract: A constant current line circuit for connection to balanced tip and ring leads of a telephone line and unbalanced transmit and receive leads of a PABX. A differential amplifier receives and applies incoming audio signals carried by the tip and ring leads to the unbalanced transmit lead, and detects D.C. loop current flowing through the tip and ring leads and generates a D.C. signal in response thereto. A voltage controlled feed current supply, connected in a circuit to the differential amplifier, generates a constant current D.C. voltage to the tip and ring leads in response to receiving the D.C. signal, and an integrator circuit is connected in a feedback path from the output of the differential amplifier to a voltage control input of the supply, for filtering audio signals received by the differential amplifier and regulating the generated D.C. signal to a quiescent value of approximately zero volts. The line circuit provides simultaneous bidirectional signal translation and constant D.C.
