This use case describes how data will travel through the AMI network. One scenario describes how the data will move from the AMI head-end to the smart meter. The second scenario describes how the data moves from the smart meter to the AMI head-end.
This use case handles the transfer of any data element from the AMI head-end to the smart meter. It is intended to be an intermediary use case, called and reused by many other use cases, The use case provides for scenarios such as meter to meter, relay to meter, and relay to relay to meter communications paths. It hides the complexity of the access point sending messages directly to a smart meter NIC and to a smart meter through a combination of relays and smart meters.
