5、onal 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 agreement has been reached by directly a

Consensus requires that all views and objections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is compl

20、.2001 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 been subjected to public review or a consensus proce

Accredited Standards Committee T1, Telecommunications serves the public through improved understanding between carriers, customers, and manufacturers. Technical Subcommittee T1E1 of Committee T1 develops tel
22、ecommunications standards and technical reports related to various digital subscriber line technologies. This standard is intended to be a living document, subject to revision and updating as warranted by advances in network and equipment technology. This standard specifies the requirements for Sing
23、le-Pair High-Speed Digital Subscriber Line (SHDSL) transceivers for use in the United States. This standard specifies ITU-T Recommendation G.991.2, Single-Pair High-Speed Digital Subscriber Line (SHDSL) Transceivers as a normative reference and identifies the requirements in ITU-T G.991.2 that are d
24、ifferent in the United States. ANSI guidelines specify two categories of requirements: mandatory and recommendation. The mandatory requirements are designated by the word shall and recommendations by the word should. Where both a mandatory requirement and a recommendation are specified for the same
25、criterion, the recommendation represents a goal currently identifiable as having distinct compatibility or performance advantages. Suggestions for improvement of this standard are welcome. They should be sent to the Alliance for Telecommunications Industry Solutions, T1 Secretariat, 1200 G Street NW
26、, Suite 500, Washington, DC 20005. This standard was processed and approved for submittal 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,
