摘要:
The present invention provides for a system and method for providing a signal to a communication system comprising an interface between a communication link and the communication system, like an alarm system, wherein the interface receives a signal from the communication link and provides a signal indicative of the availability of the communication link for use by the communication system. Alarm systems operations may be facilitated so that Residential Gateway components (such as voice terminal adapters) may simulate traditional telephone network systems that run on 48 VDC powered telephone lines. The system also comprises an input port associated with the interface for receiving the signal from the communication link, a transformer or a voltage regulator and an output port associated with the interface for providing the conditioned signal to the communication system. A ring voltage received from the communication link may be passed through to the alarm system.

A network access module having a dongle-type housing is provided. The dongle-type housing is coupleable to a computer port and when coupled to a communications network, the dongle-type network access module provides an efficient plug-and-play network connection. The network access module can be powered by a USB-port on a subscriber's computer. The subscriber can connect to a communications network using the network access module over digital subscriber lines (DSL) that use optical fiber transmission lines and optical network terminals. The network access module contains a processor for performing point-to-point access negotiation with the authentication server such that the subscriber can access the communications network without having to provide/load software.

摘要:
A device and method are provided for forming a beam of a transmit antenna array in the direction of a positioning receiver. Since the beam of the transmit antenna array is formed remotely by the positioning receiver, the received gain of the incoming positioning signal is maximized while signals from other directions are attenuated, thereby mitigating any unwanted effects of multipath. Depending on the number of elements in the transmit antenna array and their physical distribution, the width of the beam can be made finer such that the positioning receiver only requires a simple omni-directional antenna to achieve an accurate positioning solution.

A method and apparatus is disclosed for improving network performance in a communication system. A system that incorporates teachings of the present disclosure may include, for example, a server having a controller to group a plurality of wireless base terminals (WBTs) into first and second groups that share at least one common WBT and select a resultant communication path for the at least one common WBT to a mobile telephone switching office based on differential delays associated with alternative communication paths for combinations of WBTs in at least one of the first and second groups. Additional embodiments are disclosed.

Generating frequency coherence between a received reference positioning signal carrier component transmitted by at least one reference transmitter and a unique positioning signal carrier component generated by a positioning-unit device. The positioning-unit device receives a reference positioning signal and measures a frequency offset of the reference positioning signal carrier component relative to a common oscillator. Once a frequency offset is measured, the positioning-unit device adjusts a frequency steerable clock by an amount derived from the measured frequency offset. The positioning-unit device then generates a unique positioning signal carrier component at an aligned carrier frequency with the reference positioning signal carrier component. Furthermore, the positioning-unit device continuously adjusts the unique positioning signal carrier component by applying the measured frequency offset to the frequency steerable clock, which is reference to the common oscillator. Subsequently, the frequency of the adjusted unique positioning signal carrier component is aligned with the frequency of said reference positioning signal carrier component.

A system and method for providing assistance to a position receiver in a location network consisting of a Global Navigation Satellite System (GNSS) and a synchronized network of positioning-unit devices is disclosed. A positioning-unit device observes the time and frequency of received Global Navigation Satellite System (GNSS) signals relative to the synchronized network of positioning-unit devices. These time and frequency observations are modulated, as assistance data, onto the positioning signals that are broadcast by the positioning-unit devices. A position receiver demodulates the assistance data and analyzes the positioning signals. The position receiver then searches for Global Navigation Satellite System (GNSS) signals in a range responsive to the assistance data and the analysis of the received positioning signals.

A method of routing video data includes receiving data from a Video on Demand (VoD) content source at a network management system, the data indicating a first set-top box device requesting VoD content. The method also includes identifying an end node group associated with the first set-top box device. The end node group includes a plurality of set-top box devices that share a resource at the VoD content source. Further, the method includes selecting a network path between the VoD content source and the first set-top box device from a set of prospective network paths associated with the first set-top box device. The set of prospective network paths associated with the first set-top box device and network path sets associated with other set-top box devices of the end node group simultaneously satisfy a plurality of constraints related to network path delay and jitter.
