Patent number: 8972549Abstract: Methods, apparatus and computer program products allow a user of DSL or the like to implement user preferences to the extent feasible in light of operational limits and conditions. In some embodiments, an operational profile is imposed on the user. User preference data is evaluated to determine the extent to which one or more user preferences can be implemented in light of the operational profile. One or more controllers can assist in collecting user preference data, evaluating the user preference data, operational data and other data and information, and implementing user preferences as feasible. Evaluation of the user preference data and operational profile and/or data can include considering the compatibility of the user's preferences and the operational profile and/or data.Type: GrantFiled: January 28, 2006Date of Patent: March 3, 2015Assignee: Adaptive Spectrum and Signal Alignment, Inc.Inventors: Wonjong Rhee, John M.

Patent number: 8948026Abstract: Operator-controlled implementations of user preferences are provided when feasible. User preference data is obtained by the operator and compared to operational characteristics and parameters of a communication system, such as a DSL system, to determine whether one or more of the user preferences can be implemented in the communication system. When implementation of a user preference would violate operational rules of the system, or where implementation would adversely affect system operation, the preference need not be implemented. However, when a user preference can be implemented in the system without causing problems, the operator can implement (or permit another party to implement) the user preference to effect the user's desires. The user preference data can be obtained directly from users (for example, by surveys and other direct user feedback) or can be obtained indirectly (for example, by constructing a Hidden Markov Model that shows user preferences).Type: GrantFiled: January 28, 2006Date of Patent: February 3, 2015Assignee: Adaptive Spectrum and Signal Alignment, Inc.Inventors: Wonjong Rhee, John M Cioffi, Georgios Ginis, Peter J.

Patent number: 8761348Abstract: Existing and future standardized VDSL2 and other systems can be integrated into and used with a vectored DSLAM or other vectored or non-vectored DSL system, without a new user disrupting service to other users in the same or a nearby binder, in some cases by using transmit power, CARMASK and/or PSDMASK DSL capabilities to reduce both downstream and upstream training-signal levels so that training of a new DSL line is non-disruptive, despite a lack of knowledge of the pre-existing binder. For vectored systems, the crosstalk from that tone can be observed, learned and then added to the vectoring system so that any subsequent excitation on that tone would be eliminated by vector processing. A second tone then can be added in the same way, etc. In non-vectored DSLs that might be operating in a binder or line set, once these non-vectored lines are observed to be present, a vectored line set controller, such as a DSL optimizer, then can anticipate the potential interference from such non-vectored lines.Type: GrantFiled: July 29, 2011Date of Patent: June 24, 2014Assignee: Adaptive Spectrum and Signal Alignment, Inc.Inventors: John M.
