AMI – Observations Differences between systems Proprietary Communication Technology System logging and auditing Device registration – device dependant Collector Meter Substation metering Other (smart grid devices, etc) Network management interfaces Outage reporting Troubleshooting Monitoring performance System configuration and upgrades

AMI – Observations (Cont.) AMI communication vendors are not interoperable for maintenance and management Meter Collector/Access Point/Mesh Gate/Take out point/Cell Relay/Tower Gateway Base Station/ Base Station HAN ESP interface managed and implemented different between vendors

AMI-Network TF Proposal Define the devices and well defined points of interoperability within the AMI network for maintenance Define the benefits of interoperability between AMI network maintenance components to utilities Sharing backhauls Gas AMR meters Water AMR meters Hybrid AMI systems Point to Point and mesh and PLC

Proposed TF Scope Evaluate existing Maintenance Use Cases Define New Maintenance Use Cases Define System Functional Requirements for AMI meters to the AMI head end for maintenance/lifecycle purposes Identify areas within an AMI network that are viable for maintenance interoperability Scope is outside of OpenHAN and the Zigbee/Homeplug efforts Input from the Group???

Evaluate Existing Use Cases SCE use cases S1 AMI system recovers after power outage, communications or equipment failure U1 Utility installs, provisions and configures AMI system U2 Utility manages end-to-end life-cycle of the meter system U3 Utility upgrades AMI system to address future requirements Other Utility use cases AMI Vendor use cases

Define New Use Cases Focus on maintenance life cycle related activities for the meter thru the head end system Avoid HAN use cases with the exception of the AMI Communication interface with the ESP IP/3rd party gateways

Functional Requirements Create a SRS (system requirements specification) similar to OpenHAN’s efforts Derive requirements from the use case review Focus on the AMI head end to the meter from a network maintenance perspective Input from the group???
