VECTORED DSL SYSTEM, AND SUBSCRIBER LINE ADDITION METHOD AND DEVICE THEREFOR

摘要

The present invention discloses a method and an apparatus for enabling subscriber lines to join a DSL vectoring system, and the DSL vectoring system, relates to the field of communications technologies, and can shorten overall joining time of subscriber lines in a DSL system. The method includes: grouping subscriber lines into at least two groups according to time when the subscriber lines request to go online, where the at least two groups of subscriber lines that are obtained after the grouping include a first group of subscriber lines and a second group of subscriber lines, and time when all subscriber lines in the first group of subscriber lines request to go online is earlier than time when all subscriber lines in the second group of subscriber lines request to go online; starting a joining process for all the subscriber lines in the first group of subscriber lines; and during the joining process of the first group of subscriber lines, when the first group of subscriber lines reach a starting moment of a specified vectoring step, putting all the subscriber lines in the second group of subscriber lines into a joining process. The present invention can be applied to a joining process of subscriber lines in a DSL system.
