AMRA/IEEE Standards Coordinating Committee 31 (SCC31) and each of its subcommittees and working groups receive charters to develop specific standards. Following are the specific areas on which each group focuses.

• SCC31 promotes the research and development of standards, guidelines and practices in the field of telemetry technology for meter reading, energy management and customer premise equipment. The field includes automatic meter reading and energy management through telemetry technologies (telephone, radio, power-line carrier, cable, etc.) primarily for gas, electric and water utilities.
  
  
• The Procedural Oversight Subcommittee develops and maintains procedures for the proper implementation and operation of the standards process.
  
  
• The User Liaison/Education Subcommittee provides the communication link between SCC31, its subcommittees and the membership of Utilimetrics.
  
  
• The Data/Database Structure Subcommittee's goal is to define database parameters for flexible systems that are easy to upgrade, enhance and redesign.
  
  
• The Security Subcommittee specifies the functional and performance requirements of a cryptographic system for use in residential-scale automated data systems.
  
  
• The Architecture Subcommittee identifies minimal functional specifications, selected optional functions, and communication and function relationships among the various devices in the system. It also considers migration strategy issues from existing to new architecture.
  
  
• The End Device/TIU Subcommittee develops standards related to the functional performance of the meter telemetry interface.
  
  
• The TIU/Communications Interface Subcommittee identifies the functional specifications between a TIU and various communication media.
  
  
• The Language Selection Working Group is responsible for selecting an acceptable application layer language or languages for end-to-end communications.
  
  
• The Glossary Working Group maintains a glossary that lists terms used in all U.S. and international standards and provides the document to new SCC31 subcommittees and working groups.
  
  
• The Physical Element/Storage Working Group, which is temporarily inactive, defines the interface between the signal-conditioning layer and the digital-conversation layer of the end device, and between the storage layer and the analysis layer of the end device.
  
  
• The TIU/End Device Interface Protocol Working Group specifies the functional requirements for an interface between a meter and a gateway to a wide-area network, as well as the minimal functional requirements of the gateway.
  
  
• The Radio Frequency/Power-Line Carrier Working Group specifies interfaces among compatible radio-frequency, power-line carrier and hybrid networks at all applicable levels of AMR and demand-side management.
  
  
• The Telephone Working Group defines interfaces for telephone networks that comply with IEEE 1390. The specifications will be guidelines for the construction of interoperable equipment.
