Publication number: 20150146767Abstract: In accordance with embodiments disclosed herein, there are provided apparatus, systems and methods for DSM energy management. For example, in one embodiment such means include: means for adjusting transmit power on a Digital Subscriber Line (DSL line) to optimize energy consumption for the DSL line; and means for changing profile settings for the DSL line responsive to adjusting the transmit power on the DSL line until performance of the DSL line at least meets a threshold performance. For example, the means for adjusting the transmit power may involve reducing the transmit power on the DSL line to reduce total transmission energy consumption of the DSL line in accordance with one embodiment. In other embodiments, transmit power is adjusted upwards, a transmit spectra is adjusted, or effectiveness of such adjustments are measured.Type: ApplicationFiled: May 3, 2012Publication date: May 28, 2015Applicant: ADAPTIVE SPECTRUM AND SIGNAL ALIGNMENT, INC.Inventors: Kenneth Kerpez, Wonjong Rhee, Georgios Ginis

Patent number: 8477590Abstract: Crosstalk between subscriber loops used to transmit different broadband services through the same bundled telephone cable is a significant limitation to providing digital subscriber line services. A method for estimating the crosstalk, identifying the sources of the crosstalk and predicting additional sources of crosstalk are disclosed. The crosstalk sources are identified in the frequency domain by maximizing the correlation with a “basis set” of received crosstalk PSDs which consist of the cascade of a finite set of known transmit PSDs types times a representative set of crosstalk couplings. Multiple crosstalk types are identified with a technique of successive spectral subtraction. Once a type is identified the crosstalk disturber is compared against all other members of the complete set for that type. Additionally, Multiple Regression (MR) techniques and a Matching Pursuit (MP) algorithm are used to increase the ability of the system and method to identify various crosstalk disturbers.Type: GrantFiled: May 17, 2010Date of Patent: July 2, 2013Assignee: Intellectual Ventures II LLCInventors: Robert Hausman, Stefano Galli, Kenneth Kerpez

Publication number: 20060209711Abstract: The invention is a tool that accurately predicts the performance of each different priority or service level on a PON with multiple different service types and multiple users. Delays and bit rates are computed accounting for all packet, protocol, propagation, and scheduling overhead. The performance and delays of all services are further verified by running a real-time simulation that identically mimics the operation of an actual PON, resulting in very close prediction of the performances of different services before the services are actually used or tested for use by the subscribers. The invention allows the service provider to sell the maximum number of services possible, while still ensuring that they can all function acceptably. The tool may be used to model and predict behavior of various PON.Type: ApplicationFiled: January 26, 2006Publication date: September 21, 2006Inventor: Kenneth Kerpez

Patent number: 7106833Abstract: An automatic system for the provisioning, deployment and management of digital subscriber lines (DSL) in a telephone network uses data on loop composition, electromagnetic interference and crosstalk between lines to optimize the performance and correct problems with one or more symmetric and or asymmetric digital subscriber lines in a cable. The system optimizes DSL lines on an individual basis using measurements and data. The optimal transmit power spectral density (PSD) for each DSL can be found in an iterative manner. Starting each DSL with some predetermined starting parameter, the transmit PSD of each DSL is optimized in round-robin fashion. The crosstalk into a given DSL is calculated as the power sum of all transmissions passed through their measured crosstalk couplings. An asymmetric DSL has its transmit PSD optimized by using the “waterfilling” technique.Type: GrantFiled: March 27, 2003Date of Patent: September 12, 2006Assignee: Telcordia Technologies, Inc.Inventor: Kenneth Kerpez
