Abstract
In the media gateway system based on mTCA architecture, hot backup is required between two pieces of main control board. When one main control board has fault, the other main control board automaticly works as active main board, and replaces the fault board. This arti-cle has carried on the analysis to the existing scheme of main standby switch, and improved the existing schemes. The scheme was passed in high and low temperature aging test. It is reliable.关键词
