5.5.2.1
The pulse length 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
Chapter 4.5.2.1
