摘要： This invention relates to a method of dynamic line management (DLM) for a digital subscriber line. A quality of experience (QoE) measure is calculated for the digital subscriber line, and the QoE is recorded with the respective DLM line profile and also the line synchronisation rate associated with the line profile. The QoE measure is preferably based on line parameters such as a count of the error rate on the line and loss of synchronisations on the line, averaged over a predetermined period of time. Other line parameters could be used in determining the QoE measure. When DLM exhausts all the available line profiles, the invention checks to see if the QoE associated with the line profile currently being applied is an improvement on the QoE of previously applied line profiles, and if it is an improvement, then the current line profile is maintained. However, if the new QoE is not an improvement to that associated with a previously applied line profile, then the invention reverts the line back to one of the earlier line profiles. The line profile selected to revert back to is one having the same QoE or better, and if there are multiple line profiles satisfying that condition, then the line profile that has the highest associated line synchronisation rate is selected.
