3.4.4 State Diagrams
The following state diagrams describe all the action/reaction resulting from any
command or detected signal and resulting from the various operating modes.
The states, inputs and outputs are characterized as shown in the following example:
Figure 23
Example of a State with Outputs and Inputs
Each state has one or more exits to other states. These transitions depend on certain
conditions which are noted next to the transition lines. These conditions are the only
possibility to leave a state. If more conditions have to be fulfilled together, they are put
into parentheses with an AND operator (&). If more than one condition leads to the same
transition, they are put into parentheses with an OR operator (|). The meaning of a
condition may be inverted by the NOT operator (/). Only the described states and
transitions can exist.
Some conditions lead from each state to the same target state. To reduce the number of
lines and the complexity of the figures, a state named “ANY STATE” exists standing for
each state.
At some transitions, an internal timer is started. The time until the timer runs out, is noted
in curly brackets { } next to the transition line. If the end of the started time leads to a
transition from one state to another, this condition is indicated by TE (timer ended).
These actions are chosen to cope with all ISDN devices with IOM-2 standard interfaces.
The states and transitions have been prepared to prevent undefined situations. In any
case, the involved devices will enter defined conditions when the line is deactivated.
