摘要： Methods and apparatuses for reducing effects of impulse noise in a DSL transmitter receiver device are described. According to certain embodiment, the method includes using a periodicity associated with the impulse noise affecting a DSL transmitter receiver device to determine data frames that are affected by the impulse noise, and sending a reduced data rate during those frames. In certain embodiments, no data is sent during those frames. The method further includes using a high margin bits and gain table, instead of a normal bits and gain table.

摘要： An apparatus, system, and method are described for multi-carrier communication using adaptive tone-pruning. The method may include transmitting a data-bearing signal over a plurality of tones on a communication loop within a plurality of communication loops and calculating a minimum tone cost according to a tone cost algorithm. The tone cost algorithm defines a tone cost associated with a selected tone within the plurality of tones. The tone cost of the selected tone is based on a predefined loading frequency and a signal-to-noise ratio (SNR) of the selected tone. The method also may include determining a bit loading pattern for the data-bearing signal according to the minimum tone cost. This determination may occur in response to a determination that a minimum allowable transmission power is greater than a minimum required transmission power for the data-bearing signal.

摘要： A method and apparatus to transfer a data session from one device connected to a residential gateway to another. The transfer is completed within the residential gateway, without routing data through the service provider' s network. In one embodiment, a native address of a communication device engaged in an active data session is stored in a memory as a temporary device address. A session address in memory is set equal to the stored temporary device address and the temporary device address is associated with the session address in memory. When a request to transfer the data session to another device is received, the temporary device address in memory set to the native address of the new communication device and the session history is sent to the new device. Any new data received in the session, intended for the original device, is routed by a data session handling engine to the new communication device.

摘要： In an embodiment, a DSL communication device comprising a line interface circuit is disclosed. The line interface circuit includes a hybrid circuit to interface the communication device to a communication line, a lowpass transmit filter to pass signals in a first frequency band, and a highpass transmit filter to pass signals in a second frequency band, where the second frequency band is higher in frequency than the first frequency band. The outputs of the highpass and lowpass filters are coupled in parallel to the communication line. The lowpass and highpass filters as well as the low and highpass transformers are optimized for their frequency bands. Further, the edges of the low and high frequency bands are sufficiently separated to reduce interference from the other frequency band. These factors, in part, allow a multiple tone communication device to be capable of operating in multiple modes of operation with multiple DSL varieties.

摘要： A method of clock synchronization for a wireless communications system includes receiving a radio frequency (RP) signal at a base station and at a network reference server (NRS). The NRS is also coupled to receive a reference clock signal. A clock offset value is then calculated in response to the RF signal received at the base station, the RF signal received at the NRS, and the reference clock signal. A local clock signal at the base station is then synchronized with the reference clock signal in response to the calculated clock offset value.

摘要： Various methods, apparatuses, and systems in which a back up power supply is provided to a network interface device are described. In one embodiment, an apparatus includes a network interface device (NID) located outside a building and a power supply unit located inside the building. The power supply unit has one or more ports that couple via a phone line to the NID to provide a power signal to the NID. The apparatus further includes a direct current (DC) back up power unit located in the NID. The DC back up power unit provides back up power to the NID. The NID is configured to periodically switch between receiving the power signal from the power supply unit and the DC back up power unit even when no fault condition exists in the power supply unit.
