Abstract

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. Controllers assisting users can include a local controller at the user'"'"'s location, one or more upstream-end local controllers, one or more remote location controllers, and/or one or more other downstream-end device controllers at locations other than the user'"'"'s location. Data and information can be shared among the various controllers, either using the DSL system itself or using a proprietary or other alternative data system.
