System and method for realizing veneer active/standby changeover in communication equipment

Abstract

A system and method for realizing active-standby switchover in communication equipment, in which cross switches are respectively set in each main control board and service board, a pair of signal input and output ends of the cross switch in each main control board are connected to a processing module, and the remaining pairs The signal input and output terminals are respectively connected to a pair of signal input and output terminals of the crossbar switch in each service board; a pair of signal input and output terminals of the crossbar switch in each service board are connected to the service module, and the remaining pairs of signal input and output terminals are respectively connected to each A pair of signal input and output terminals of the crossbar switch in the main control board are connected correspondingly; The corresponding control signal is input at the input end to control the switching of the crossbar switch to realize the master-standby switchover. The invention is convenient to realize, has little impact on the service, and can improve the reliability and the switchover speed of the system.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a system and method for realizing active / standby switchover of a single board in a communication device. Background technique [0002] Communication equipment is a physical entity that completes specific functions in the communication network. In the communication network, in order to ensure the continuity of the network work, some equipment is required to work 24 hours a day, so the key components of the equipment are designed with redundancy and double backup. It can support active and standby hot backup work, and ensure that when the main component fails, it can be smoothly switched to the standby component without causing service interruption. At the same time, when building a network, the integrated functions of a single device need to be implemented in layers. In addition to supporting the active and standby states, the single boards of different functional mo...
