1、 AMERICAN NATIONAL STANDARD FOR TELECOMMUNICATIONS ATIS-0300231.01.2003(R2007) Digital Subscriber Line (DSL) Layer 1 In-Service Digital Transmission Performance Monitoring ATIS is the leading technical planning and standards development organization committed to the rapid development of global, mark

2、et-driven standards for the information, entertainment and communications industry. More than 250 companies actively formulate standards in ATIS 20 Committees, covering issues including: IPTV, Service Oriented Networks, Home Networking, Energy Efficiency, IP-Based and Wireless Technologies, Quality

3、of Service, Billing and Operational Support. In addition, numerous Incubators, Focus and Exploratory Groups address emerging industry priorities including “Green”, IP Downloadable Security, Next Generation Carrier Interconnect, IPv6 and Convergence. ATIS is the North American Organizational Partner

4、for the 3rd Generation Partnership Project (3GPP), a member and major U.S. contributor to the International Telecommunication Union (ITU) Radio and Telecommunications Sectors, and a member of the Inter-American Telecommunication Commission (CITEL).

5、NAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial

6、 agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made towards their resolution. The us

7、e of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American Nation

8、al Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards In

9、stitute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require

10、that action be taken periodically to reaffirm, revise, or withdraw this standard.

11、l Standard for Telecommunications Digital Subscriber Line (DSL) Layer 1 In-Service Digital Transmission Performance Monitoring Secretariat Alliance for Telecommunications Industry Solutions Approved October 22, 2003 American National Standards Institute, Inc. Abstract This standard provides performa

12、nce monitoring functions and requirements applicable to DSL digital transmission lines. This standard provides functional requirements to support maintenance and is not meant to be an equipment specification. This standard is one of a set of standards for specific applications utilizing the common c

13、riteria as specified in T1.231-2003. ATIS-0300231.01.2003 ii Foreword The information contained in this Foreword is not part of this American National Standard (ANS) and has not been processed in accordance with ANSIs requirements for an ANS. As such, this Foreword may contain material that has not

14、been subjected to public review or a consensus process. In addition, it does not contain requirements necessary for conformance to the standard. This American National Standard is one of a series of maintenance operations standards developed by Technical Subcommittee T1M1 of Committee T1 - Telecommu

15、nications. Committee T1 standards serve the public through improved understanding between carriers, end-users, and manufacturers. This standard specifies a basic set of monitoring requirements, and provides criteria that are common to a set of standards, the T1.231 series, which define applications

16、for a specific level in the digital hierarchy. The documents, which are included in the T1.231 series (at the time that this document is approved), are listed below: T1.231-2003, Digital Hierarchy Layer 1 In-Service Transmission Performance Monitoring. T1.231.01-2003,DSL Layer 1 In-Service Transmiss

18、N Layer 1 In-Service Transmission Performance Monitoring. (This standard is not yet approved.) This particular standard will be useful to anyone engaged in the design, provisioning, or operation, of telecommunications equipment or services, utilizing DSL digital transmission technology. The standard

19、 establishes uniform and consistent performance monitoring functions and requirements applicable to Layer1 DSL digital transmission lines. This standard is intended to be a living document, subject to revision and updating as warranted by advances in digital transmission technology Compliance with t

20、he standard should provide uniform and consistent measurement parameters and techniques for DSL circuits, facilities, and networks. In some cases, location-oriented options are needed to ensure compatibility: this need for options is imposed by significant differences between network providers as we

21、ll as between network elements Requirements are designated by the word shall, while recommendations utilize the word should. Requirements specify the minimum acceptable functionality for effective performance monitoring in a network element; recommendations identify functionality that may enhance pe

22、rformance monitoring capabilities for some users. Suggestions for the improvement of this standard will be welcome and should be sent to the Alliance for Telecommunications Industry Solutions, 1200 G Street, NW, Suite 500, Washington, DC, 20005. This standard was processed and approved for submittal

23、 to ANSI by Accredited Standards Committee on Telecommunications, T1. Committee approval of the standard does not necessarily imply that all members voted for its approval. At the time it approved this standard, the T1 Committee had the following members: E.R. Hapeman, T1 Chair W.R. Zeuch, T1 Vice-C

44、rates. It is to be used in conjunction with the core document - T1.231-2003. This document is part of the T1.231 series, which supersedes and replaces T1.231-1997 in its entirety. This standard currently contains sections addressing requirements for ADSL and HDSL signals. The requirements in this do

45、cument supersede and replace Annex M of T1.413-1998 and Annex G of T1.418-2002. Requirements for other versions of DSL (such as VDSL and SHDSL) are for further study. 2 Normative References The following standards contain provisions, which through reference in this text constitute provisions of this
