This invention relates to a switch method for converting primary control and backup boards of communication devices, PCB and service boards, which sets an interface chip, conversion logic control chip and CPU in each PCB and service board and the interface chip is connected with that of the service board to be connected with the local service process module and the CPU, the conversion control logic chips are connected with those of the opposite PCB and service boards to receive and transmit master and backup instructions or alarm signals, the logic chips of the boards are connected with the local interface chip and CPU to send link switch signals to the local interface chip based on the received instructions or alarm signals and the interface chips only receive data of master links based on the link switch signal at the receiving direction.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a communication device and a method for realizing active / standby switchover of a main control board and a service board. Background technique [0002] In order to meet people's demand for "communication barrier-free", one of the primary tasks of the telecommunication network is to ensure its high reliability. A telecommunication-grade network should not have any single point of failure. In order to ensure the reliable operation of telecommunication equipment, telecommunication equipment manufacturers use 1+1 backup in many cases to solve the impact of possible failures in network operation on actual services, how to maximize the switching speed in case of failures and Reducing the impact on services is the key to the 1+1 protection scheme, especially when the main control board and service board support the 1+1 protection scheme at the same time, regardless of whether the s...
