Functional Description
2.4.10 State Machines for Line Activation / Deactivation
2.4.10.1 Notation
The state machines control the sequence of signals at the U-interface that are generated
during the start-up procedure. The informations contained in the following state diagrams
are:
– State name
– U-signal transmitted
– Overhead bits transmitted
– C/I-code transmitted
– Transition criteria
– Timers
Figure 45 shows how to interpret the state diagrams.
