Transmission over the S/T-interface is performed at a rate of 192 kbit/s. 144 kbit/s are
used for user data (B1+B2+D), 48 kbit/s are used for framing and maintenance
information.
Line Coding
The following figure illustrates the line code. A binary ONE is represented by no line
signal. Binary ZEROs are coded with alternating positive and negative pulses with two
exceptions:
For the required frame structure a code violation is indicated by two consecutive pulses
of the same polarity. These two pulses can be adjacent or separated by binary ONEs.
In bus configurations a binary ZERO always overwrites a binary ONE.
