The message is sent to the AMI Head-End and routed to the appropriate smart meter. When the message is received at the NIC ESP, it is converted and sent on to the Meter Metrology Board where the reading is taken and sends the data back to the NIC ESP to the AMI Head-End. The AMI Head-End sends the information to the CIS for the Customer Service Representative (CSR) to read and to the Operational Data Store (ODS) where it is logged as a meter event.
