Depending on the selection of the synchronization signals (SYPR or RFM), different
calculation formulas are used to define the position of the synchronization pulses. These
formulas are given below, see
of SYPR and RFM is always the basic E1 bit width (488 ns), independent of the selected
system highway clock and data frequency.
