23、0 ETSI TS 103 097 1 does not use the finite state machine concept. As consequence, the test purposes use a generic “Initial State“ that corresponds to a state where the IUT is ready for starting the test execution. Furthermore, the IUT shall be left in this “Initial State“, when the test is complete

24、d. Being in the “Initial State“ refers to the starting point of the initial device configuration. There are no pending actions, no instantiated buffers or variables, which could disturb the execution of a test. 5.1.4 Sources of TP definitions All TPs have been specified according to ETSI TS 103 097
