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