Project documentation (in Russian)
Current work, as work , using SWITCH-technolody, implements the model of
push-button telephone and the automatic telephone station (ATS)
Differences with the program  are:
implemented new telephone's functions - the posibility to accept calls and to
enter the telephone number after the receiver was lifted out;
new method of cooperation of automatas, which implements telephone and ATS.
This method was called "postponed automata call". In differences with
method, described in , it allows:
to move out the reenterability of automata's functions;
to realize the parallel work of automatas in the different threads;
to process external events, arriving from parallel threads, after their
preliminarily saving in the queue
Method keep graph notation, proposed in  and using in the work .
Postponed automata call have following features:
Project implemented on Java language.
inner and outer automata states are not differs;
all events moves to the queue for each automata and process consecutive;
automatas self calling is possible.
Project was tested using automatically generated log-files and automatas graph's
