摘要： An ONU includes circuit cards, a card cage, and electrical connector hardware. The card cage releaseably engages and supports the circuit cards in installed positions in the card cage. At least one pair of the circuit cards have serial interconnections with each other. The electrical connector hardware defines all of those serial interconnections and is free of a backplane.

摘要： A multi-service, adaptable optical network unit (ONU) is disclosed for use in a fiber-to-the-curb (FTTC) digital loop carrier system, including a multi-service common card and a plurality of multi-media service cards that are connected to the common card using a card-link interface. The card-link interface is preferably a high-speed LVDS serial-bus connection that is organized in a star configuration such that each service card is connected to the multi-service common card using a separate point-to-point card-link. By eliminating the traditional backplane structure found in present ONU designs, the present invention provides a scalable, adaptable, future-proof FTTC system that can transport present-day multi-media services as well as yet-to-be-defined future high-bandwidth applications.

摘要： An improved digital loop carrier system for transporting voice and DSL data signals in the local loop. The digital loop carrier system includes a remote digital terminal having an interface terminal, a common equipment shelf for interfacing digital voice signals to the central office switch, and a plurality of copper shelves coupled to the common shelf for holding voice line-cards that convert digital voice signals into analog voice signals (and vice versa) for transport to customer premises. At least one copper shelf is configured to include an auxiliary packet data bus for connecting combination voice/DSL line-cards and at least one data uplink card. The data uplink card is coupled to the interface terminal to enable DSL data transport without impacting digital voice capabilities through the common equipment. Also disclosed is an optional Ethernet switch in the remote digital terminal for concentrating multiple DSL signals prior to transport back to the central office.

摘要： A four quadrant power conversion topology comprising a multi-winding inductor, four switches, and four diodes is disclosed. The four quadrant power conversion is utilized in a number of power conversion devices such as a power efficient non-linear power amplifier that comprises the 4Q power conversion topology of the present invention and a switch-control-signal generator coupled to the 4Q power conversion topology. The switch-control-signal generator generates switch activation signals for driving the four switches of the 4Q power conversion topology. In one embodiment the switch-control-signal generator comprises a polarity detector for detecting the polarity of an input signal, a full wave rectifier for rectifying the input signal, a pulse width modulator which produces a pulse width modulated signal representative of the full wave rectified input signal, and steering logic that generates switch activation signals for driving the power conversion topology to produce an output representative of the input signal. The amplifier may optionally include switch drivers to condition the switch activation signals to drive the switches in the 4Q power conversion topology.
