2 Summary: Each has a secured optical port that can be interfaced and programmed with a computer equipped with Vendor Firmware Tool. A utility meter technician can connect the Vendor Firmware Tool to the Smart via the optical port and upload (apply) programming and firmware upgrades. Narrative: A Smart can have its firmware upgraded through the Smart s Optical port. The electrician will load new firmware through the Vendor Firmware / Program Tool software using a laptop computer equipped with an optical probe. The meter will acknowledge the successful competition or the failure. The AMI Head-End system will receive an acknowledgment of the program change upon completion or failure.

4 Actor(s): The list of the actors and the roles that are participating in this use case described in the table below. Name AMI Head-End Metrology Board ODS Vendor Firmware / Program Tool Role description The AMI Head-End is the back office system than controls the Advanced ing, which serves as a repository for data extracted from the meters and manages routing and schedules of the network. The board, internal to the Smart, on which the functions of the Smart are configured and performed. The is a plug-in board to the host meter that provides AMI communication. The Network Interface Card within the Smart has different elements (ESI & ). The provides communications with the ing System. The provides communications with the Home Area Network (HAN). Operational Data Storage for meter events, etc. A tool to develop meter programs. These programs are then loaded into the AMI Head-End. It also could be used in the field for direct meter updates Participating Business Functions: The participating business function, its acronym and what they provide in this use case are detailed in the table below. Acronym Business Function/Abstract Component Services or Information Provided Assumptions / Design Considerations: Standard International Electrotechnical Commission (IEC) Message Definition format will be followed to provide the Header, Request, Reply, and payload used when defining the messages for the design specifications. For the purpose of the use cases identified in this document these have been omitted as they are to be provided in the design specification for the In-Field Programming of Smart and Firmware use case.

5 Normal Sequence: The sequences of events, showing the order in which they ocurr during the typical progression of this use case are provided in the table below. The Sequence Diagram that graphically depicts the events is presented immediately following the table.

7 In-Field Programming of Smart and Firmware Sequence Diagram Integration Scenarios Adapters will use the Common Information Model (CIM) in Extensible Markup Language (XML) to send and receive messages and events. The following are the points of integration that must be tested for this use case. Other non-cim message interfaces may be testable in this use case.

8 Pre-conditions: None The following conditions that MUST be met before this use case can occur. Post-conditions: The following events or actions that may happen after or be caused by the completion of the normal use case events, as well as the exceptions or alternative sequences are: Smart has loaded the new firmware/program. AMI Head-End has the proper status of the new meter firmware/program and current program version. Exceptions / Alternate Sequences: There are no exceptions, unusual events or alternate sequences defined for this use case. Use Case Step Triggering Event Description Of Process Information To Be Exchanged Producer Receiver Message Type Message Type(s) Diagram: None An XML Schema Definition (XSD) diagram shows the normative and informative parts of the message. Not all of the International Electrotechnical Commission s (IEC) CIM message optional elements must or will be used in the use of IEC CIM for this specific use case.
