Embodiment Construction

[0015] The method for switching the communication channel among the standby boards of the present invention is to realize the communication channel by setting the control register through the CPU to generate the strobe signal or by the hardware circuit to generate the strobe signal through the processing of the main standby state and the on-off state of the communication channel. automatic switching.

[0016] Using the method described in the present invention, through the change of the connection relationship between the two boards in the system (the switching system of this board, the communication channel of this board, and the connection conversion between the backplane interface), there is no need to change the connection of any external communication channel relationship, normal communication can be realized, that is to say, from the interface of the docking device, there is no change in the connection relationship of the communication channel.

[0017] Only one of the t...

Abstract

The invention relates to a method for switching communication channels between backup boards, wherein said backup board comprises: the first working board and the second working board; the first working board is connected to the communication channel. And said method comprises: when checking the first working board is in main application state, and the second working board is in backup state.

Description

technical field [0001] The invention relates to a method for switching communication channels between mutually serving as standby boards, in particular to a method for switching Ethernet communication channels between mutually serving as standby boards in the communication field. Background technique [0002] In the communication network, in order to achieve reliable communication, the uplink business communication board in the important communication equipment will be backed up. However, only single-board backup cannot guarantee reliable external communication, and a reliable external communication channel must also be provided. In the existing mutual backup mode, in order to provide a reliable external communication channel, there are currently two main solutions: communication channel backup and manual switching. Communication channel backup is to provide physical communication channels on the two boards A and B that are mutually standby to connect with the docking equip...
