System For Dsl Modem Type Identification

View page
US Patent:
7349963, Mar 25, 2008
Filed:
Nov 4, 2004
Appl. No.:
10/981068
Inventors:
Wonjong Rhee - San Francisco CA, US
Iker Almandoz - Palo Alto CA, US
Assignee:
Adaptive Spectrum and Signal Alignment, Inc. - Redwood City CA
International Classification:
G06F 15/173
US Classification:
709224
Abstract:
Operational data collected from a communication system, such as a DSL system, may include exclusionary data and/or indicative data that can be analyzed to determine the type of communication device, such as a DSL modem, that generated the operational data. Exclusionary data, if any, can be used to exclude one or more communication device types from consideration. Indicative data, if any, may be used to influence the selection of a communication device type, such as by assigning scores to communication device type features and/or to communication device types. Information pertaining to various communication devices may be maintained in a database or the like. In a DSL system, modem types may be evaluated and selected by a modem identification unit or identifier that collects and analyzes the operational data using collecting means and identifying means. The identifier may be part of a controller, such as a DSM Center or the like implemented in and/or with a computer and coupled to the DSL system. Information such as a modem type selection then can be used by the controller to generate modem and/or system operation signals to assist in operation of the DSL system.

Digital Subscriber Line (Dsl) State And Line Profile Control

View page
US Patent:
7460588, Dec 2, 2008
Filed:
Mar 3, 2005
Appl. No.:
11/071762
Inventors:
Wonjong Rhee - Palo Alto CA, US
Iker Almandoz - Palo Alto CA, US
John M. Cioffi - Atherton CA, US
Assignee:
Adaptive Spectrum and Signal Alignment, Inc. - Redwood City CA
International Classification:
H04B 1/38
US Classification:
375222
Abstract:
Disclosed are systems and methods for evaluating whether to transition operation of a DSL line from a current line profile to one or more target line profiles. For example, in one embodiment, a method provides providing a profile transition matrix, a plurality of threshold tables, a plurality of sub-rules, and an overall rule. The method operates in the current profile and collects operational data on the DSL line. The method further performs one or more tests to evaluate the feasibility of the current line profile and each of the target line profiles, and then transitions the state to operate the DSL line in the highest feasible profile available. Evaluation of the feasibility of staying in the current state or moving to one of the target states may be based on distributions of reported and estimated data distilled from the operational data collected on the DSL line.

Dsl Data Collection System

View page
US Patent:
7535966, May 19, 2009
Filed:
Aug 17, 2004
Appl. No.:
10/919620
Inventors:
Wonjong Rhee - Palo Alto CA, US
John M. Cioffi - Atherton CA, US
Assignee:
Adaptive Spectrum and Signal Alignment, Inc. - Redwood City CA
International Classification:
H04L 27/00
H04M 11/00
US Classification:
375260, 379 9001
Abstract:
Information is sent by a DSL system component using a non-disruptive operational data parameter. One or more bits of the non-disruptive operational data parameter are used to send other information. In some instances the selected parameter will be an unused parameter, such as an unused fast operational mode or interleaved operational mode parameter used to report operational data in a DSL system. In one embodiment of the invention, a remote modem provides a unique equipment identifier that can be paired with the telephone number on which the modem is operating. Verification of and/or searching for the correct pairing of telephone number and unique equipment identifier can be performed as well.

Adaptive Margin And Band Control In Digital Subscriber Line (Dsl) Systems

View page
US Patent:
7558315, Jul 7, 2009
Filed:
Jul 19, 2004
Appl. No.:
10/893826
Inventors:
John M. Cioffi - Atherton CA, US
Wonjong Rhee - Palo Alto CA, US
Assignee:
Adaptive Spectrum and Signal Alignment, Inc. - Redwood City CA
International Classification:
H04B 1/38
US Classification:
375222
Abstract:
Controlling margins in a DSL modem pair is based on collected operational data. The operational data is analyzed and at least one of the modems in the modem pair is instructed to use a margin-related parameter value to assist the modem pair in meeting a margin target, such as a margin limit imposed by a DSL standard or the like. A controller, such as a DSM Center, a “smart” modem unit and/or a computer system can collect and analyze the operational data and generate one or more margin-related parameter values. The margin-related parameter value may be a PSD-related value, such as the MAXNOMPSD, MAXNOMATP or PSDMASK parameter used by various ADSL systems, and may be a shaped spectral mask and/or caps or limits on bit loading for use in transmissions between the modems. In some cases, preference bands can be imposed to direct modems to favor and/or avoid certain frequencies in the modem's usable band(s). The operational data may include historical data relating to prior performance of the modem pair and prior margin compliance.

Incentive-Based Dsl System

US Patent:
7606350, Oct 20, 2009
Filed:
May 5, 2005
Appl. No.:
11/122428
Inventors:
John M. Cioffi - Atherton CA, US
Wonjong Rhee - Palo Alto CA, US
Assignee:
Adaptive Spectrum and Signal Alignment, Inc. - Redwood City CA
International Classification:
H04M 1/24
H04M 3/08
H04M 3/22
US Classification:
379 103, 379 104, 370252, 375225, 375240, 37524005
Abstract:
Improved DSL and/or other communication system services can be provided by motivating users, service providers and operators to implement and comply with one or more operational conditions, such as parameter value limits and/or ranges, that enhance operation of the communication system. Enhanced operation can include providing a reward such as an operational benefit to one or more users and/or mitigating problems experienced by other users in the communication system, which can be one or more communication lines. A DSL line implementing and complying with one or more operational conditions is provided with a reward (such as an operational benefit like a higher maximum data rate), which is otherwise withheld if the line fails to comply with the condition(s). Each operational condition may be set and monitored by a controller, such as a DSL optimizer that collects and analyzes operational data to determine compliance. Other requirements may be imposed for a DSL line to be eligible for the reward, such as the requiring the DSL line to provide operational data to the controller and requiring the DSL line's acceptance of control signals from the controller.

Dsl System Estimation And Control

View page
US Patent:
7684546, Mar 23, 2010
Filed:
Jan 28, 2006
Appl. No.:
11/342024
Inventors:
Wonjong Rhee - Palo Alto CA, US
John M. Cioffi - Atherton CA, US
Bin Lee - Palo Alto CA, US
Iker Almandoz - Palo Alto CA, US
Georgios Ginis - San Francisco CA, US
C. Thomas Sylke - Whitefish Bay WI, US
Assignee:
Adaptive Spectrum and Signal Alignment, Inc. - Redwood City CA
International Classification:
H04M 1/24
H04M 3/08
H04M 3/22
US Classification:
379 104, 379 103, 379 2909
Abstract:
Methods, apparatus, computer program products and other embodiments model a system's channel and noise characteristics using one or more Hidden Markov Models (HMMs) by modeling the state dynamics for one or more lines and associated profiles and by learning from the line history. Besides channel and noise characteristics, user data activity also can be modeled using an HMM, where all channel, noise and user data activity can be modeled jointly using HMMs as long as the joint states are properly defined. In multi-line systems, multiple lines (for example, a set of lines in a DSL system binder) may be modeled jointly. After learning channel, noise, user data activity and/or other dynamics using HMM techniques and methods, system operation and/or configuration parameters can be controlled based on the estimated HMM, providing flexible solutions for virtually any channel, noise, user data activity and/or other dynamics.

Dsl System Estimation And Parameter Recommendation

View page
US Patent:
7711530, May 4, 2010
Filed:
Nov 26, 2007
Appl. No.:
11/945210
Inventors:
John M. Cioffi - Atherton CA, US
Wonjong Rhee - Palo Alto CA, US
Assignee:
Adaptive Spectrum and Signal Alignment, Inc. - Redwood City CA
International Classification:
G06F 7/60
H04N 7/173
US Classification:
703 2, 725111
Abstract:
Estimates of a communication system configuration, such as a DSL system, are based on operational data collected from a network element management system, protocol, users and/or the like. The operational data collected from the system can include performance-characterizing operational data that typically is available in an ADSL system via element-management-system protocols. Generated estimates and/or approximations can be used in evaluating system performance and directly or indirectly dictating/requiring changes or recommending improvements in operation by transmitters and/or other parts of the communication system. Data and/or other information may be collected using “internal” means or may be obtained from system elements and components via email and/or other “external” means. The likelihood of a model's accuracy can be based on various data, information and/or indicators of system performance, such as observed normal operational data, test data and/or prompted operational data that shows operating performance based on stimulation signals. One example of such prompted data uses frequency carrier masks to approximate the Hlog of a given channel, including information regarding bridged taps attenuation, etc.

Phantom Use In Dsl Systems

View page
US Patent:
7773497, Aug 10, 2010
Filed:
Nov 4, 2005
Appl. No.:
11/267623
Inventors:
John M. Cioffi - Atherton CA, US
Bin Lee - Mountain View CA, US
Wonjong Rhee - Palo Alto CA, US
Georgios Ginis - San Francisco CA, US
Assignee:
Adaptive Spectrum And Signal Alignment, Inc. - Redwood City CA
International Classification:
H04L 5/20
US Classification:
370200
Abstract:
Superimposing phantom-mode signals reinforces existing differentially driven DSL downstream signals in a vectored binder of DSLs or reinforces upstream vectored signals in a binder of differentially excited twisted pairs, thus expanding the extra transmission modes of the previous GDSL multi-wire two-sided-excitation invention to the case where coordination can only occur on one-side of the binder. Each pair is treated as a common-mode antenna with respect to earth ground, with some pairs selectively excited at the transformer center tap at the transmit end with respect to a common (earth or chassis) ground reference. Corresponding receivers on other non-excited pairs sense the signals between their center taps and a ground at the opposite ends of the lines to the exciting transmitters. A dual use with hybrid circuits allows the receiving circuit to also have an upstream transmitter and an upstream-sensing receiver on the center tap of the opposite side of an adjacent wire.
