摘要： 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.

摘要： Methods and systems for twisted pair telephone line diagnostics based on patterns of line data occurring over time. An observed data distribution is classified as periodic or based on modeled distributions previously determined to correspond to a known line activity, fault type, or fault location. A disruption or parameter value pattern is classified through statistical inference of operational and performance data collected from the line. Where the disruption and/or parameter value(s) correlate with a time the customer is at the customer premises, an inference is made that the line fault causing the disruption is more likely at the CPE than at the Central Office. Where the disruption distribution is classified as being a result of human activities initiated on the line, a fault condition associated with the activity is inferred. Where a disruption pattern is correlated with human initiated plain old telephone service (POTS), a micro-filter problem is inferred for the line.

摘要： Methods and systems to improve accuracy and fault detection capability of automated line diagnostics through at least one of: joint processing of SELT and DELT data; comparisons of relative strengths of peaks and/or dips to envelope and/or peaks to dips in a time domain echo response; and iterative diagnostics whereby an echo response is adjusted through signal processing techniques, for example to remove lengths of straight line, between successive performance of a detection algorithm. More than one of the diagnostic systems and methods described herein may be employed in combination to improve accuracy and fault detection capability. For example, where SELT and DELT data are jointly processed, analysis of the SELT data may employ the ratio tests described in the context of a SELT diagnostic routine. Similarly, the SELT diagnostics method assessing relative strengths of peaks and dip in an echo response via ratio tests may be combined with iterative adjustment of the echo response.
