Full Description

Scope

This standard details the criteria required for communication between a C12.21 Device and a C12.21 Client via a modem connected to the switched telephone network. The C12.21 Client could be a laptop or portable computer, a master station system, or some other electronic communications device. This standard does not specify the implementation requirements of the telephone switched network to the modem, nor does it include definitions for the establishment of the communication channel. This document provides details for an implementation of the Open Systems Interconnection (OSI) seven-layer model in accordance with ISO/IEC 7498-1. The protocol specified in this standard was designed to transport data in Table format. The Table definitions are in ANSI C12.19 and in Annex D of this document.This standard specifies the differences between ANSI C12.18-2006 and ANSI C12.19-1997 and the features and services required to describe a protocol specification for telephone modem communications.

Purpose

The utility industry has need for a standard that provides an operable "plug and play" environment for field metering devices. The purpose of this standard is to define the means to transport the Utility Industry End Device Data Tables via a telephone modem so that multisource environment and End Device interchangeability is possible.

Abstract

New IEEE Standard - Active.This standard provides multisource and "plug and play" environment for the millions of metering devices in the field now and in the future using the telephone modem communication interface. It solves the problems associated with single-source systems and with multisource systems based upon proprietary communications protocols. Electric, water, and gas utilities and corresponding vendors can realize cost savings that ultimately shall benefit the client consumers of the utilities.
