Meter Data Management system
A meter data management (MDM) system collects and stores meter data from a head-end system and processes that meter data into information that can be used by other utility applications including billing, customer information systems, and outage management systems.
A head-end system (HES) is hardware and software that receives the stream of meter data brought back to the utility through the AMI. Head-end systems may perform a limited amount of data validation before either making the data available for other systems to request or pushing the data out to other systems.
Device Language Message Specification
Device Language Message Specification (DLMS) is the suite of standards developed and maintained by the DLMS User Association (DLMS UA) and has been adopted by the IEC TC13 WG14 into the IEC 62056 series of standards.
Companion Specification for Energy Metering
Companion Specification for Energy Metering (COSEM) includes a set of specifications that defines the transport and application layers of the DLMS protocol. The IEC 62056 standards are the international standard versions of the DLMS/COSEM specification.
Wide Area Network
A wide area network (WAN) is a telecommunications network that extends over a large geographic area for the primary purpose of computer networking. Wide area networks are often established with leased telecommunication circuits.
Home area network
A home area network (HAN) is a network contained within a user’s home that connects a person’s digital devices, from multiple computers and their peripheral devices to telephones, VCRs, televisions, video games, home security systems, smart appliances, fax machines and other digital devices that are wired into the network.
Controllable local system
Controllable local system (CLS) management systems encapsulate SMGW-specific requirements and provide interfaces for DSMgrs that offer a direct communication channel to control boxes.
Local Metrological Networks
A Local Metrological Network (LMN) is a local measuring device network that forms the interface to smart meters.
Advanced Metering Infrastructure
Advanced metering infrastructure (AMI) refers to the infrastructure with two-way communications for metering and associated systems allowing the delivery of a wide variety of services and applications for both the generators, transmission and distribution system operators and the customers.
Key Management System
A key management system (KMS) is an integrated approach for generating, distributing and managing cryptographic keys for devices and applications.
Hand-Held Units (HHU) are devices used for automated meter readings.
