Embodiment Construction

[0039] The main purpose of the present invention is to provide a device and a switching method for each level of DSLAMs that can respectively realize the switching of the main control board and the standby main control board when the multi-level DSLAMs are connected by optical fibers, so as to overcome the deficiencies in the prior art , so that the main and standby main control boards in each DSLAM can provide backup, and the switching process of the main and standby main control boards in each DSLAM does not affect other DSLAMs, thereby improving the stability and reliability of the optical network.

[0040] The device described in the present invention includes the main main control board, the standby main control board and the optical path adapter included in the DSLAMs at all levels. The DSLAMs at all levels include the main DSLAM and the slave DSLAM. The standby main control boards are connected by an optical path adapter, which provides interconnection paths between the ...

Abstract

Using light splitter carries out adapted connection between main and standby master control boards in multiple stages of digital subscriber line access multiplexer (DSLAM). Thus, main master control board and standby master control board in each stage can be exchanged flexibly. Scheme of linked exchange is not necessary in the invention. Thus, back up function is realized in each stage of DSLAM. The invention raises reliability and stability of exchanging between main master control board and standby master control board in large capacity DSLAM broadband access system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a device for realizing backup of multi-level communication equipment and a method for realizing active-standby switching. Background technique [0002] Active / standby switchover is a necessary function for the long-term reliable operation of the system. With the construction of broadband access network and the deployment of a large number of comprehensive services such as voice and video, the stability of broadband network has become a must. One of the most important functions is the system The active / standby switchover function is a requirement for broadband equipment and data communication equipment in the broadband network. [0003] DSLAM (Digital Subscriber Line Access Multiplexer) is a common equipment in broadband access network. DSLAM access equipment can be divided into two types, frame-type broadband access equipment and box-type broadband access equipment. It co...
