3.2.11 Backplane
Within the DIB-R5 advanced, the backplane serves as central communication and supply
element. The backplane provides the synchronization signals (clock and time) and the
ethernet connections between the BSCUs and the CHUs and supplies the components
with operating voltage.
Then following figure shows the backplane from the rear view of the DIB-R5 advanced.
The following table describes it in detail.
