5.5.1.1
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 T1/J1 bit width (648 ns) in 1.544-MHz mode or
the E1 bit width (488 ns) in 2.048-MHz mode.
This chapter describes the system highway operation in 1.544-MHz mode only. If the
system highway is operated in 2.048-MHz mode, the description given in
