Description

Digital subscriber line DSL processing method and device

Technical field

This document relates to, but is not limited to, the field of communications, and more particularly to a method and apparatus for processing a digital subscriber line (DSL).

Background technique

Among several broadband access technologies, a variety of digital subscriber loop (xDSL) technologies can make full use of existing copper resources. xDSL is a general term for various types of digital subscriber lines (DSL). Users enjoy stable bandwidth, good confidentiality, and mature performance, becoming the mainstream means of broadband access. The Digital Subscriber Line Access Multiplexer (DSLAM) is an xDSL central office access device. The xDSL client access device is called a modem. The connection between Modem and DSLAM can transmit user data called DSL building chain. This connection relationship is disconnected into DSL chain. Some parameters need to be set on the DSLAM to standardize some indicators of the DSL chain construction, such as the link establishment rate. These parameters become the DSL line configuration parameters.

The DSL line configuration parameters are statically configured. For example, when a user is opened, a set of DSL line configuration parameters are set to the DSLAM according to the distance of the user and the type of service purchased by the user. However, due to changes in the physical condition of the line, such as line aging, noise interference around the line, etc., these will affect the DSL construction chain, such as the link-building rate becomes lower or even DSL is broken.

There is a need to have a way to assess the stability of the DSL chain. In the related technology, it is to collect the user's report, and when the user's complaint is received, the line is marked as unstable. Obviously, this does not meet the requirements of telecom operators to provide quality services to users.

For lines marked as unstable, the improvement method is to communicate with the user by the maintenance personnel or to go to the door to locate the fault, which will increase the cost of the operator and reduce the response speed of the fault processing.
