Abstract: Data indicative of a level of stability of a DSL link is received. Based on the received data, it is determined whether the data indicates a level of stability of the DSL link that is above or below and minimum threshold. If the level of stability of the DSL link is below the minimum threshold, die noise associated with the DSL link before the time of failure is compared with the noise of failure. If the difference between the noise before and after the time of failure exceeds a threshold, then the difference in noise is characterized as a stationary noise associated with the DSL link. However, if the difference between the noise before and after the time of failure is below the threshold, a determination is made whether the failure is associated with a loss of power to the DSL link or a severe impulse noise event the difference in noise is characterized accordingly. Finally, the characterization of the noise associated with the DSL link is preserved for subsequent possible reconfiguration of the DSL link to improve link stability.

Abstract translation: 接收到指示DSL链路的稳定性水平的数据。 基于接收到的数据，确定数据是否指示DSL链路的稳定度高于或低于最小阈值。 如果DSL链路的稳定度低于最小阈值，则与故障之前的DSL链路相关联的模块噪声与故障噪声进行比较。 如果故障之前和之后的噪声之间的差异超过阈值，则噪声的差异被表征为与DSL链路相关联的稳定的噪声。 然而，如果故障之前和之后的噪声之间的差异低于阈值，则确定故障是否与DSL链路的功率损耗相关联或严重脉冲噪声事件，噪声的差异被表征 相应地。 最后，保留与DSL链路相关联的噪声的表征，以便随后可能重新配置DSL链路以改善链路稳定性。

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.
