This document is identified by three numbers, MC1218-2009, ANSI C12.18-2006 and IEEE 1701-200X. The standard details the criteria required for communications with a Utility End Device by another device via an optical port. The other device could be a hand held reader, a laptop or portable computer, a master station system, or some other electronic communications device. It shall provide the optical port lower layers communication protocol for the Utility metering Industry including specifically… read more Water, Gas, and Electric. The Standard provides details for a complete implementation of an OSI 7-layer model in accordance with ISO/IEC 7498-1. The protocol specified in this document was designed to transport data in Table format. The Table definitions are in ANSI C12.19 (MC1219, IEEE 1377) Utility Industry End Device Data Tables. read less

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.

In the "Protocol Specification for ANSI Type 2 Optical Port" Standard (ANSI C12.18/MC12.18/IEEE 1701), a point-to-point protocol was developed to transport table data over an optical connection. The ANSI C12.18 / MC12.18/IEEE 1701 protocol include an application language called Protocol Specification for Electric Metering (PSEM) that allows applications to read and write Tables. The "Protocol Specification for Telephone Modem Communication" (ANSI C12.21/MC12.18/IEEE 1702) was then developed to… read more allow devices to use PSEM to transport Tables over telephone modems. This standard extends the concepts of ANSI C12.18/MC12.18/IEEE 1701, ANSI C12.21/MC12.18/IEEE 1702, and ANSI C12.19/MC12.19/ IEEE 1377 standards to allow transport of Table data over any reliable networking communications system. Note that in this use of the word, "reliable" means that for every message sent, the sender receives a response at its option: either a positive acknowledgment or an error message. That is, messages cannot fail silently in a reliable network (see discussion of Reliable Stream Transport Service in IPPA [B1]).2 In addition, this standard describes an optionally exposed point-to-point interface between a C12.22 Device and a C12.22 Communications Module designed to attach to "any" network. The terms "C12.22 XXXX" (e.g., C12.22 Device) were introduced by ANSI C12.22-2008. These terms can be interchangeably replaced with the terms "IEEE 1703 XXXX"; i.e., the IEEE 1703 Device is the same as the ANSI C12.22 Device and the IEEE 1703 Communication Module is the same as the C12.22 thiCommunication Module. However, since this standard was originally developed under the auspice of ANSI C12 SC17 WG1, the document terminology is based on C12.22 terms. Furthermore,s standard defines a methodology to capture, translate, and transmit one-way device messages (blurts). read less

This document is a non-industry-specific recommended practice for voltage-sag ride-through performance and compliance testing for all electrical and electronic equipment connected to low-voltage power systems (with nominal/rated voltage less than 1000 V) that can experience malfunction or shutdown as a result of reductions in supply voltage lasting less than one minute. The recommended practice includes defining minimum voltage-sag immunity requirements based on actual voltage-sag data. A… read more clause dedicated to the detailed analysis of voltage sags experienced by end users provides insight into real-world voltage sags. Testing procedures and requirements for test equipment are clearly defined within this document to reflect the electrical environment, including single-phase, two-phase, and three-phase, balanced and unbalanced voltage sags. The recommended practice also defines requirements for certification and test reporting, including characterization of voltage-sag ride-through equipment. read less
