Patent number: 11477081Abstract: 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: January 15, 2020Date of Patent: October 18, 2022Assignee: ASSIA SPE, LLCInventors: John Cioffi, Wonjong Rhee, Sumanth Jagannathan, Peter Joshua Silverman, Mehdi Mohseni, Georgios Ginis

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: 8340279Abstract: An adaptive interference cancellation system is described. In one example the system operates by receiving a data signal using a DSL (Digital Subscriber Line) and receiving a reference signal, the reference signal corresponding, in part, to noise on the data signal. The reference signal is classified and a noise cancellation signal is applied to the data signal based on the classification.Type: GrantFiled: October 5, 2007Date of Patent: December 25, 2012Assignee: Adaptive Spectrum and Signal Alignment, Inc.Inventors: Sumanth Jagannathan, Chiang-yu Chen, John Cioffi
