Embodiment Construction

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The digital subscriber line ports on the line card can be divided into two categories. Usually, these ports are randomly distributed on the line card. As long as there is one subscriber line port in use on the line card, the line card cannot be powered off, resulting in the energy efficiency of the line card. very low. In this embodiment of the present invention, a subscriber line migration module is added to the digital subscr...

Abstract

The embodiment of the invention discloses a method for accessing a digital subscriber line, and a device and equipment thereof. The method comprises the following steps: acquiring the port status of a subscriber line; controlling the subscriber line ports for transferring the subscriber line ports in a use status and the subscriber line ports in an out-of-use status to different line cards according to the port status of the subscriber line; and cutting power of the line card on which the subscriber line ports are all in the out-of-service status. The technical scheme provided by the embodiment of the invention controls the subscriber line ports for transferring the subscriber line ports in a use status and the subscriber line ports in an out-of- service status to different line cards by acquiring the status information of the subscriber line ports, and cuts power of the line card on which the subscriber line ports are all in the out-of- service status, so as to reduce the power consumption for accessing the digital subscriber line.

Description

technical field [0001] The present invention relates to the technical field of communication access, and in particular, to a digital subscriber line access method, apparatus and device. Background technique [0002] Digital Subscriber Line (DSL, Digital Subscriber Line) technology is a high-speed transmission technology for data transmission through telephone twisted pairs. [0003] The DSL access system consists of a digital subscriber line access multiplexer (DSLAM, Digital Subscriber Line Access Multiplexer) and a customer premises equipment (CPE, Customer Premise Equipment) located in the central computer room (CO, Central Office), such as figure 1 shown. DSLAM is the access node of DSL, which is mainly composed of DSL subscriber line card, control card and voice splitter; client equipment includes data terminal equipment such as set-top boxes, computers, etc. Road (Digital Subscriber Loop) connection, the function of DSL Modem is similar to that of line card.
