Functional Overview	2

Rear Transition Modules (RTM) are important components in many telecommunications and embedded systems. These environments place most of the active components on a Front Board and most of the cable connections (especially copper cables) are made from the RTM. This allows the Front Board to be replaced without the need to reinsert a large number of cables in the correct order.

In AdvancedTCA* systems, the Front Board mates directly with the RTM, as shown in Figure 1:
