Summary:

This use case addresses the messages exchanged between CIS and Smart Meter through the AMI Head-End and AMI Network when a meter connect/disconnect request is issued by CIS.

Narrative: Traditionally, utilities send a metering service person to connect or disconnect the meter. With an AMI system, the connect/disconnect can be performed remotely by switching the internall meter switch in the Smart Meter for any of the following possible reasons:

Remote Connect for Move-In Remote Connect for Reinstatement on Payment Remote Disconnect for Move-Out Remote Disconnect for Non-Payment Remote Disconnect for Emergency Load Control Unsolicited Connect / Disconnect Event

A remote disconnect is issued in the Customer Information System (CIS) by the Customer Service Representative (CSR) for a legitimate reason. The message is sent to the AMI Head-End and routed to the appropriate Smart Meter via the AMI Network. When the message is received at the NIC (part of the Smart Meter), it is converted and sent on to the Meter Metrology Board (part of the Smart Meter) where the board causes the Internal Meter Switch (part of the Smart Meter) to connect or disconnect (depending on the command) and sends a confirmation back to the Meter Metrology Board to the NIC to the AMI Head-End via the AMI Network. The AMI Head-End sends the confirmation to CIS and to the Operational Data Store (ODS) where it is logged as a meter event.

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.

Actor Interface Points

CIS • AMI Head-End

AMI Head-End • AMI Network • ODS

Pre-conditions:

The following conditions that MUST be met before this use case can occur.

• CIS must have a list of valid Meter IDs

• Meter to be connected/disconnected must be installed and registered with the AMI head-end system

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:

• If the Meter does not respond after the Remote Connect/Disconnect comand, further actions will be required from the CSR.

Exceptions / Alternate Sequences:

There are no exceptions, unusual events or alternate sequences defined for this use case.
