Indicates if the EMS is able to keep the current EMS data synchronized with the current NE data and generate all appropriate notifications.  The EMS sets this attribute to false to indicate that it requires resynchronization with NE data and that it is not able to generate the appropriate notifications (such as OCs/ODs/AVCs) while doing so.
The EMS sets this attribute back to true when the resynchronization is completed and when notifications can start being generated as appropriate.
Changes in the value of this attribute lead to a State Change notification.
