Summary: This use case addresses the messages exchanged between CIS and Smart Meter through the AMI HeadEnd 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.
