The invention relates to a method for automatically optimizing quality of a
digital subscriber line (DSL)
broadband. The method comprises the following steps: real-time and timing
broadband line data collection, accessing into
multiplexer DSLAM equipment by using a
digital subscriber line, so as to finish data collection, monitoring and service Web request, wherein the invention particularly proposes a post-collection
data analysis technology, which mainly provides initial data for line diagnosis and line optimization, line stability judgment, which is used for providing a judgment index for stability optimization; line diagnosis, dividing a
broadband line into three standards of a line with speed-up potential, a line free of speed-up potential and a line unable to speed up according to
data analysis and preset standard reaching rules; a line optimization process, which is divided into an assignment work order treatment process and an automatic iterative optimization process. The method has the beneficial effects that the condition that maintenance personnel comprehend the concrete reasons of quality decline of the
digital subscriber line DSL broadband, carry out targeted door maintenance and remove hidden dangers of the DSL broadband line in advance is facilitated, so that
user perception is improved, and customer complaint is reduced.
