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 H log of a given channel, including information regarding bridged taps attenuation, etc.

Abstract: Methods, apparatus, systems and computer program products address one-sided vectoring systems that include a bonded-line set having two or more bonded DSL lines within a vectored group wherein other techniques such as precoding, tonal predictive GDFEs, tonal rotors and ordering techniques can be implemented. The performance of lines within a bonded set for a single customer can be improved for both upstream and downstream by nesting a vector coding system within, for example, GDFE and/or precoder architectures. The DSL lines within such a bonded group can have rotors applied at both transmit and receive side to achieve higher performance for these lines. The triangular matrix used by the GDFE and the precoder systems of the above-referenced applications can be modified in this context.

Abstract: 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). The operator may collect the user preference data from a user set (for example, a single user or a plurality of users). The user preference data can be compared to 2 or more performance metrics that can be adjusted, to the extent feasible, to implement the user preference data.

Abstract: Adaptive generalized decision feedback equalization (GDFE) allows variations in one or more channels and noise of a multi-line/multi-channel communication system to be tracked. Such tracking can be used in vector upstream (one-sided) situations in communication systems such as ADSL and VDSL, among others. The GDFE may be separated into adaptive and static portions and/or components. Either a feedforward section or a feedback section (or both) can be separated to create a static component and an adaptive component. The adaptive components adjust to the instantaneous channel and noise changes (for example, using the instantaneous errors and simple LMS algorithms). When the channel and noise do not exhibit any time-variation, the adaptive filters can zero themselves. Local updating of adaptive feedforward and/or feedback filters addresses rapid changes to the spatial correlation of noise and/or changes to the multi-line channel (for example, time-variation due to temperature changes, component variations, mechanical stress, and other reasons), without disruption to separate static feedforward and/or feedback filters supplied by a controller, such as a DSL optimizer or the like that can assist by doing the heavier calculations and providing vectoring information and data to the DSL line components. An efficient implementation is provided of any triangularization of the binder channel that characterizes multi-user vectored-DMT DSL. Adaptation also allows correction of any inaccuracy in initially or previously reported crosstalk transfer functions and noise spatial correlation.

Abstract translation: 自适应广义判决反馈均衡（GDFE）允许跟踪多线/多通道通信系统的一个或多个信道和噪声的变化。 这样的跟踪可以用于诸如ADSL和VDSL之类的通信系统中的向量上行（单向）情况。 GDFE可以分成自适应和静态部分和/或部件。 可以分离前馈部分或反馈部分（或两者）以创建静态组件和自适应组件。 自适应组件调整到瞬时通道和噪声变化（例如，使用瞬时误差和简单的LMS算法）。 当信道和噪声不显示任何时间变化时，自适应滤波器可以自己归零。 自适应前馈和/或反馈滤波器的本地更新解决了噪声和/或多线路信道变化的空间相关性的快速变化（例如，由于温度变化，组件变化，机械应力和其他原因引起的时间变化 ），而不会破坏由控制器（例如DSL优化器等）提供的分离的静态前馈和/或反馈滤波器，其可以通过进行较重的计算并向DSL线路部件提供向量化信息和数据来辅助。 提供表征多用户向量DMT DSL的绑定通道的任何三角化的有效实现。 适应还允许校正初始或先前报告的串扰传递函数和噪声空间相关性中的任何不准确性。

Abstract: A Device Abstraction Proxy (DAP) interface receives a request for operational data relating to Digital Subscriber Line (DSL) services provided to a plurality of DSL terminals in a DSL network by two or more providers. The DAP interface receives, in response to the request, the operational data, including operational data for a plurality of DSL lines coupled to the plurality of DSL terminals. The DAP then identifies at least two of the plurality of DSL lines as belonging to a common neighborhood of DSL lines, each of the at least two of the plurality of DSL lines respectively associated with at least two of the plurality of DSL terminals being provided the DSL services by different providers. Embodiments correlate a condition and/or a performance of one of the at least two DSL lines identified as belonging to the common neighborhood with a condition and/or performance of another one of the at least two DSL lines identified as belonging to the common neighborhood.

Abstract: 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.
