MPRTM0020 Technical Product Specification – April 2006 9
Functional Overview
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:
