Communications device single board active/standby changeover apparatus and implementation method

Abstract

This invention discloses one communication device signal board main prepare inversion device, which comprises main prepare inverse control module and bus, wherein, the main prepare inverse control module is to receive input signals to fulfill single board main prepare inverse control; bus interface unit connected to the bus, wherein, the bus interface unit is to receive series signals into parallel signals to main prepare inversion module; the said bus interface unit si to convert received parallel signals into series signals to bus.

Description

technical field [0001] The invention relates to a 1+1 thermal active / standby configuration technology for functional single boards in communication equipment, and specifically relates to a communication equipment single board active / standby switchover device and an implementation method. Background technique [0002] Usually, the two functional boards in the 1+1 hot master / standby redundancy configuration in the communication equipment are mutual masters and backups, and the two boards are connected through several hardware direct connection signals on the backplane, and the boards use These signals are used for active / standby control and switching, including the active / standby status output signal of each board, the active / standby status input signal of the opposite board, the online output signal of each single board, the online input signal of the opposite board, the reset signal of each single board, and the heartbeat signal Wait, there are also plans to use the followin...

Problems solved by technology

However, it will cause the "parallel" signal line to be locked, and must be solved by other means. Part of the "parallel" signal lines are not interconnected or short-circuited, which directly leads to the failure of the main-standby switching circuit, and even serious dual-active or dual-standby states.
