Data Sheet
2.3.5.1.1 State Transition Diagram
The state machine includes all information relevant to the user. The state diagram
notation is given in figure 41.
The informations contained in the state diagrams are:
– State name
– U
– C/I code received (commands) (see chapter 2.3.5.1.3)
– C/I code transmitted (indications) (see chapter 2.3.5.1.6)
– Transition criteria
The transition criteria is grouped into:
– C/I commands (see chapter 2.3.5.1.3)
– Received infos on U
– Reset (see chapter 2.3.5.1.5)

State Diagram Notation
The following example illustrates the use of a state diagram with an extract of the state
diagram. The state explained is “Deactivated”.
The state may be entered:
– from states “Power-Up”, “Pending Deactivation”, “Pending Activation”, “Loop3” and
The following informations are transmitted:
– INFO 0 (no signal) is sent on the U
– C/I message “DC” is issued on the IOM-2 interface.
The state may be left by either of the following methods:
– Leave for the state “Power up” after synchronous or asynchronous “TIM” code has
– Leave for state “Pending Activation” in case C/I = AR is received.
the unconditional states “Reset” and “Test Mode i” after the C/I command “DI” has
been received.
