Data Sheet
2.3.4.1.1
The state machine includes all information relevant to the user. The state diagram
notation is given in figure 36.
The informations contained in the state diagrams are:
– State name
– Signal received from the line interface (INFO) (see chapter 2.3.4.1.4)
– Signal transmitted to the line interface (INFO) (see chapter 2.3.4.1.7)
– C/I code received (commands) (see chapter 2.3.4.1.3)
– C/I code transmitted (indications) (see chapter 2.3.4.1.6)
– Transition criteria
The transition criteria is grouped into:
– C/I commands (see chapter 2.3.4.1.3)
– Signals received from the line interface (INFOs) (see chapter 2.3.4.1.4)
– Reset (see chapter 2.3.4.1.5)
Figure 36
State Diagram Notation
As can be seen from the transition criteria, combinations of multiple conditions are
possible as well. A “ ” stands for a logical AND combination. And a “+” indicates a logical
OR combination.
The sections following the state diagram contain detailed information about all states and
signals used.
Figure 37 shows the state transition diagram of the SCOUT-DX state machine.
Figure 38 shows this for the state Loop 3.
