== Backplane architecture ==
The AdvancedTCA backplane provides point-to-point connections between the boards and does not use a data bus. The backplane definition is divided into three sections; Zone-1, Zone-2, and Zone-3. The connectors in Zone-1 provide redundant −48 VDC power and Shelf Management signals to the boards. The connectors in Zone-2 provide the connections to the Base Interface and Fabric Interface. All Fabric connections use point-to-point 100 Ω differential signals. Zone-2 is called "Fabric Agnostic" which means that any Fabric that can use 100 Ω differential signals can be used with an AdvancedTCA backplane.<ref>{{cite web|last1=Bolaria|first1=Jag|title=Understanding backplane, chip-to-chip tech|url=http://www.eetimes.com/document.asp?doc_id=1266762|website=EETimes|accessdate=9 August 2017|date=2004-12-20}}</ref>
The connectors in Zone-3 are user defined and are usually used to connect a front board to a Rear Transition Module. The Zone-3 area can also hold a special backplane to interconnect boards with signals that are not defined in the AdvancedTCA specification.
