摘要： Methods, techniques and apparatus identify members and characteristics of binders and/or other groups of communication lines such as those in a DSL system. Information obtained includes the identification (for example, by scanning) of significant crosstalking "offenders" and their "victims" that are affected by the crosstalk. One or a small number of modems are instructed to transmit with preselected transmit spectra, after which evidence of crosstalk in the noise spectrum data is examined for potential victim lines. Direct evidence of noise spectrum contribution by a suspected offender line may be obtained by collecting reported noise spectrum data and/or estimated noise spectrum data from potential victim lines. For DMT modulated DSL transceivers, well designed transmit spectra can be easily enforced by manipulating line profiles where such well designed line profiles cause minimal or no interruption to existing DSL customers.

摘要： 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. The controller can use the operational data and line control to enhance system operation, for example to reduce crosstalk between lines in a common binder.

摘要： Loading and ordering techniques are provided for one-sided and two-sided vectored line groups, as well as loading methodologies that also can be used on a single line, in communication systems such as DSL binders. For single-user lines, bits and energy are optimally allocated for a given set of parameters, which may include maximum rate, minimum rate, maximum margin, target margin, minimum margin and PSD mask of any shape. Iterations, bit-swapping during loading or adaptive margin update during loading can be used in single-user loading, which has low complexity and can be used for a variety of loading objectives and/or goals, such as rate-adaptive, margin-adaptive and fixed-margin objectives. For multi-user vectoring systems, ordering as well as loading is provided for a supplied rate-tuple within a rate region, determining acceptable user loadings and orderings so that the rate-tuple can be implemented. For one-sided vectored DSL, some loading and ordering determines acceptable allocations of bits, energy and decoding/precoding ordering(s) for each tone of each user for a specified set of rates on the vectored lines. PSD determination, ordering and bit allocation can be iteratively used in multi-user loading and ordering and can augment and alter the criteria used for bit swapping procedures used in single lines (or in bonded multiple lines for a single user) so that a favorable vector of rates is achieved for all users. Order swapping can adjust a bit vector and/or rate vector within a constant-rate-sum convex subset of a hyperplane towards the desired vector of user rates for each of the lines.
