A table of Join Window time periods. Management Application creates an entry in the table to add a Join Window period and its recurrence pattern. If csiJoinWindowConfigOperationMode is 'auto', all devices joined during Join Window are automatically upgraded. If csiJoinWindowConfigOperationMode is 'manual', new devices joined during Join Window are put on hold as indicated in csiDeviceStatus. They are not offered upgrade information unless the operator manually instructs the director to do so. In rare occasions, when entries overlap in time, the devices joining during any of the Join Window period are allowed to be upgraded or put on hold.
