Patent number: 9420090Abstract: Methods and systems for twisted pair telephone line diagnostics based on patterns of line data occurring over time. An observed data distribution is classified as periodic or based on modeled distributions previously determined to correspond to a known line activity, fault type, or fault location. A disruption or parameter value pattern is classified through statistical inference of operational and performance data collected from the line. Where the disruption and/or parameter value(s) correlate with a time the customer is at the customer premises, an inference is made that the line fault causing the disruption is more likely at the CPE than at the Central Office. Where the disruption distribution is classified as being a result of human activities initiated on the line, a fault condition associated with the activity is inferred. Where a disruption pattern is correlated with human initiated plain old telephone service (POTS), a micro-filter problem is inferred for the line.Type: GrantFiled: April 13, 2012Date of Patent: August 16, 2016Assignee: Adaptive Spectrum and Signal Alignment, Inc.Inventors: Mehdi Mohseni, Mohamad Charafeddine, Chan-Soo Hwang, Ardavan Maleki Tehrani

Patent number: 9391744Abstract: 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 and 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 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.Type: GrantFiled: January 23, 2014Date of Patent: July 12, 2016Assignee: Adaptive Spectrum and Signal Alignment, Inc.Inventors: John M.

Patent number: 9203724Abstract: Methods, techniques, computer program products, apparatus, devices, etc., used in connection with DSL Management Interfaces, significantly improve the management capabilities of a DSL network and/or improve testing relating to DSL equipment and services by permitting better control and operation of a DSL system, including implementation of timestamping for more accurate measurement, monitoring and control of a system. Timestamping further allows customized data collection techniques, where a DSL line can be measured or monitored at intervals whose frequency depends on the line's stability. Moreover, data parameter read and control parameter write operations are presented in conjunction with the use of timestamping. Also, control and operation of a DSL system is enhanced by implementing bit-loading that minimizes, eliminates or otherwise mitigates the amount by which the SNR margin per tone exceeds a maximum SNR margin quantity, where such bit-loading can be selected through an appropriate interface.Type: GrantFiled: August 22, 2011Date of Patent: December 1, 2015Assignee: Adaptive Spectrum and Signal Alignment, Inc.Inventors: John M.
