NEW TERMINOLOGY <br />AMI — Advanced Metering Infrastructure includes devices and systems that measure, collect and <br />analyze usage, and communicate with metering devices. The AMI system includes a TUNet ( Tantalus <br />Utility Network) interface where data is validated and passed through to other connected systems. The <br />AMI system allows for two way communications with metering endpoints. <br />MDMS — Meter Data Management System is a term used to refer to a metering data storage and analytic <br />system primarily used to store History of Interval data from the AMI head end system, which collects <br />usage and metering data from meter endpoints; the MDMS also includes the account number and <br />communication devices identification hardware. <br />Provisioning - Provisioning is the process by which enQuesta notifies MDMS and Front ends AMI system <br />of impending changes or discrepancies in metering data so as to maintain synchrony and prevent MDMS <br />from initiating unintended actions. For example, a Meter Exchange work order initiated in enQuesta <br />provisions MDMS to prevent MDMS from "overreacting" to the signal interruption that will occur <br />25H -98 Page 91 <br />
