Object Lifecycle Analysis

Each object in FTM has a lifecycle defined by a finite state machine (FSM) model. Table 1 shows the FSMs that are used to manage the lifecycle of the FTM objects for the ACH Services reference application.

Table 1. ACH Services Reference Application Finite State Machines Used
FSM	Type	Object
Generic : Inbound Physical Transmission	PT	Control total origination
Inbound Control Total Transaction	Transaction	Control total origination

The generic finite state machines handle most of the objects used by the ACH Services reference application. An FSM is needed for each of the objects shown in Table 2.
