Introduction This introduction is not par
7、t of IEEE Std 1702-2011, IEEE Standard for Telephone Modem Communication Protocol to Complement the Utility Industry End Device Data Tables. This standard provides an open-platform communications protocol for two-way communication with a metering device via a telephone modem. The protocol is written
8、 to conform to the Open Systems Interconnection (OSI) seven-layer stack. Long-time readers of ANSI C12.21-1999 will discover many editing changes to this version of the standard. The End Device/Telemetry Interface Unit Subcommittee 1701/1702 Working Group chose to improve the clarity of the text as
9、an aid to the reader while retaining the normative elements in the manner of previous publications. The 2006 revision to ANSI C12.21 was considered in the context of the so-called “protocol suite” of ANSI standards: ANSI C12.18 / MC1218 / IEEE Std 1701, ANSI C12.19 / MC1219 / IEEE Std 1377, ANSI C12
10、.21 / MC1221 / IEEE Std 1702, and ANSI C12.22 / MC1222 / IEEE Std 1703. Changes made were included only after assuring that existing devices implementing ANSI C12.18-1996 would continue to remain compatible with this version of the document. It is expected that the Logoff Service will become mandato
11、ry in the next revision of this standard. Implementers are strongly encouraged to support this service to comply with this change. Notice to users The body of this standard was developed jointly with ANSI C12.21 and MC1221. The joint agreement calls for the standards and regulatory organizations IEE
12、E, ANSI and MC to maintain the body of this standard in step as they publish versions and revisions of the standard. A number of editorial errors and error of omission where discovered since the publication of ANSI C12.21-2006, just before the acceptance of IEEE 1702. These errors are listed in Anne
13、x J Listing of Editorial Errors and Errors of Omission in ANSI C12.21-2006. All reported errors were identified in the body of this standard and highlighted to indicate that the text was in error and was corrected. Errors of omission were corrected in the body of this document and similarly highligh
14、ted. Laws and regulations Users of these documents should consult all applicable laws and regulations. Compliance with the provisions of this standard does not imply compliance to any applicable regulatory requirements. Implementers of the standard are responsible for observing or referring to the a
15、pplicable regulatory requirements. IEEE does not, by the publication of its standards, intend to urge action that is not in compliance with applicable laws, and these documents may not be construed as doing so.

Overview
39、1.1 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 devi
40、ce. 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-
41、layer model in accordance with ISO/IEC 7498-1.1The 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 t
42、he features and services required to describe a protocol specification for telephone modem communications. 1Information on references can be found in Clause 2.

43、right 2011 IEEE. All rights reserved. 1.2 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 telephon
44、e modem so that multisource environment and End Device interchangeability is possible. 2.
