15.5 Action/Event
Action/event is the name of the table's events that are the possible triggers for the entire
protocol state machine. Those can be selected from the list of events in the CASSetup.h
file (e.g., EV_DISCONNECT_INCOMING).
At the beginning of the state, there can be up to 4 special unconditional action/events
called FUNCTION. They events are functions that are unconditionally performed when the
table reaches the state. These actions are labeled FUNCTION0 to FUNCTION3.
The following is the list of available protocols table actions (events to the state machine):
1. User Command Oriented:
•
EV_PLACE_CALL - When using acPSTNPlaceCall().
•
EV_ANSWER - When using acPSTNAnswerCall().
•
EV_DISCONNECT_OUTGOING - When using the function
acPSTNDisconnectCall() and the call is outgoing.
•
EV_DISCONNECT_INCOMING - When using the function
acPSTNDisconnectCall() and the call is incoming.

EV_RELEASE_CALL - When using acPSTNReleaseCall()
•
EV_USER_BLOCK_COMND - When using acCASBlockChannel(), this event

start the timer to get the Off event (refer to the
EV_METERING_TIMER_PULSE_OFF below.).
•
EV_METERING_TIMER_PULSE_OFF - event after timer (SET_PULSE_TIMER
