The ConnectionConfigurationSetStateMachineType and the corresponding set of Methods (see ConnectionConfigurationSetType) and Events (subtypes of the ConnectionConfigurationSetEventType) are illustrated in Figure 39.
Figure 39 – ConnectionConfigurationSetStateMachineType illustration
Methods and Events illustrated in Figure 39 are defined in subsequent clauses. The ConnectionConfigurationSetStateMachineType is formally defined in Table 87. StateType and TransitionType only exist in the type system; thus, they do not have a modelling rule.

Ready – A ConnectionConfigurationSet in this State may be processed by the ConnectionManager.
Processing – A ConnectionConfigurationSet in this State indicates that it is currently being processed by the ConnectionManager (i.e., Connections are being established). Internals of the processing executed in this State are described in 6.7.5.3.
Error – A ConnectionConfigurationSet in this State indicates an error has occurred during Processing.
ReadyToProcessing – This transition shall be initiated by the ProcessConnectionConfigurationSets Method Call. In addition, this state transition may also be initiated by vendor-specific means. While being in State Processing, the ConnectionManager establishes or closes the Connections contained in the ConnectionConfigurationSet; for details, see 6.7.5.3.
ProcessingToReady – This transition shall be initiated if the ConnectionManager succeeds in processing all of the Connections contained in the ConnectionConfigurationSet.
ProcessingToError – This transition shall be initiated if the ConnectionManager fails the processing of any Connection contained in the ConnectionConfigurationSet.
Information about the success or failure of the establishment of specific Connections is provided by the ProcessingResult Property in ConnectionConfigurationType.
ErrorToProcessing – This transition shall be initiated by the ProcessConnectionConfigurationSets Method Call. In addition, this state transition may also be initiated by vendor-specific means.
