Wherein, described multiplex/demultiplex module is between Switching Module and ATCA Zone2.

Wherein, described backboard comprises and is used for the basic passage and the optical-fibre channel that are connected with the ATCA backboard.

Wherein, when described compatible board is a power board, described PMC module is provided with one or more PMC subcard, be used to realize that the up link of power board connects, described Switching Module be used for realizing OSI seven layer protocols second, third, the 4th agreement, be used to support being redirected and bag classification, filtration and the load-balancing function of the 3rd/the 4th layer protocol of various routes, the 4th layer protocol of forwarding, the 3rd layer protocol of second layer agreement.

Wherein, when described compatible board was a business board, described PMC module was provided with the PMC subcard, by the PMC subcard, was used to realize the types of functionality of business board.

The utility model has realized that business board and power board unite two into one, and makes compatible board promptly can be used for business board, also can be used for power board, and can use on each groove position of ATCA system.Improve ATCA product versatility, flexibility and compatibility, reduced the maintenance and the production cost of ATCA platform, more met the thought of ATCA technology---openingization, modularization, standardization.

Further specify the utility model below in conjunction with drawings and Examples.
