20090161741 | Methods and Apparatus to Combine Data from Multiple Sources to Characterize Communication Systems - A data collector combiner, a network management system, a DSL Optimizer (DSLO), or any combination thereof collects data, parameter(s), characteristic(s), information, or any combination thereof from two or more data sources. The data collector probabilistically combines at least the first and second data to estimate at least one DSL characterizing parameter. | 06-25-2009 |
20090168972 | Methods and Apparatus to Perform Line Testing at Customer Premises - A data analyzer operative to be located at a customer premises, causes the transmission of a probing signal into at least one telephone line. The data analyzer computes a parameter that represents a characteristic of at least one telephone line based upon at least a measured reflected probing signal. | 07-02-2009 |
20090207985 | DSL System - An apparatus comprises at least one vectoring engine and a cross-connect coupled to the vectoring engine. The cross-connect is to couple with each of a plurality of customer premises equipment (CPE) devices via a respective DSL loop. An interface is to receive instructions for the cross-connect to couple the vectoring engine to a nonoverlapping subset of the CPE devices via the respective DSL loops. The interface is further to receive instructions for the vectoring engine to apply vectoring to the DSL loop via which to couple one of the CPE devices to the cross-connect. | 08-20-2009 |
20090323903 | METHOD AND APPARATUS FOR ANALYZING AND MITIGATING NOISE IN A DIGITAL SUBSCRIBER LINE - Data indicative of a level of stability of a DSL link is received. Based on the received data, it is determined whether the data indicates a level of stability of the DSL link that is above or below a minimum threshold. If the level of stability of the DSL link is below the minimum threshold, die noise associated with the DSL link before the time of failure is compared with the noise associated with the DSL link after the time of failure. If the difference between the noise before and after the time of failure exceeds a threshold, then the difference in noise is characterized as a stationary noise associated with the DSL link. However, if the difference between the noise before and after the time of failure is below the threshold, a determination is made whether the failure is associated with a loss of power to the DSL link or a severe impulse noise event—the difference in noise is characterized accordingly. Finally, the characterization of the noise associated with the DSL link is preserved for subsequent possible reconfiguration of the DSL link to improve link stability. | 12-31-2009 |
20100074312 | HIGH SPEED MULTIPLE USER MULTIPLE LOOP DSL SYSTEM - A high speed multiple user multiple-loop DSL system is described. In one embodiment, it includes a first DSL loop to carry DSL traffic to a first user and a second DSL loop to carry DSL traffic to a second user. A first junction connects the traffic of the first DSL loop to a third DSL loop, and a second junction connects the traffic of the second DSL loop to the third DSL loop. | 03-25-2010 |
20100166051 | Video Streaming Diagnostics - A video stream DSL analyzer receives at least non-physical layer management data and physical layer management data and in response generates metric information. The generated metric information is used to characterize the performance of the video stream information and diagnose any problems if necessary. In response to the metric information, the video stream DSL analyzer changes one or more DSL configuration(s) in order to improve performance. | 07-01-2010 |
20100232486 | METHOD AND APPARATUS FOR REDUCING NOISE IN A COMMUNICATION SYSTEM - A system that incorporates teachings of the present disclosure may include, for example, a controller to: determine crosstalk coupling characteristics between a plurality of lines of a Digital Subscriber Line (DSL) system connected to a plurality of modems based on a transition between a full power mode and one or more other modes, and provide the determined crosstalk coupling characteristics to one or more of the plurality of modems for performance of at least one of pre-coding a transmitted signal and processing a received signal along a line of the plurality of lines, where the pre-coding and processing is performed based at least in part on the determined crosstalk coupling characteristics, and where the pre-coding of the transmitted signal and the processing of the received signal reduce effects of fluctuating crosstalk. Other embodiments are disclosed. | 09-16-2010 |
20120134397 | METHOD AND APPARATUS FOR DSL PERFORMANCE ENHANCEMENT IN A DSL NETWORK - A Digital Subscriber Line (DSL) Management Center (DMC) coupled to a DSL network includes a data collection module that receives information regarding the DSL network from a plurality of sources. An analysis module is coupled to the data collection module to analyze the received information and issue a command for one or more of a plurality of DSL performance enhancement devices to optimize their operation. A command signal generation module is coupled to the analysis module to receive the issued command from the analysis module and generate a corresponding command signal for transmission to one or more of the DSL performance enhancement devices. | 05-31-2012 |
20130022178 | DETECTION OF WIRING DEFECTS - A method for detecting a defect in wiring in a DSL system. The method includes collecting data including instantaneous values, a history of values, and/or parameters relating to a central office or customer premises equipment, analyzing a line for a wiring defect based on the collected data, and reporting whether or not a wiring defect was detected responsive to the analyzing step. | 01-24-2013 |
20140369480 | SYSTEMS, METHODS, AND APPARATUSES FOR IMPLEMENTING A DSL SYSTEM - An apparatus comprises at least one vectoring engine and a cross-connect coupled to the vectoring engine. The cross-connect is to couple with each of a plurality of customer premises equipment (CPE) devices via a respective DSL loop. An interface is to receive instructions for the cross-connect to couple the vectoring engine to a nonoverlapping subset of the CPE devices via the respective DSL loops. The interface is further to receive instructions for the vectoring engine to apply vectoring to the DSL loop via which to couple one of the CPE devices to the cross-connect. | 12-18-2014 |
