Embodiment Construction
[0013] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.
[0014] Fig. 1 is the structural schematic diagram of the existing main and backup device with an external plus one-of-two circuit. With reference to Fig. 1, in this service interface board backup mode, the two service interface boards connect the outside lines and the main and backup control lines through the backplane. To the outside, place a two-choice circuit outside, control the outside two-choice circuit through the main and backup control lines, and select different lines to connect with the outside line to achieve the purpose of backup. There are many control circuits in this way, the structure is complex, and it is unreliable.
[0015] FIG. 2 is a schematic structural diagram of an existing master-slave device. Referring to FIG. 2 , this is another service interface board backup method in the prior art. This method generally adopt...
