AMERICAN NATIONAL 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
6、 established when, in the judgment of the ANSI Board of Standards Review, substantial 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 objection
7、s be considered, and that a concerted effort be made towards their resolution. The use 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 pr
8、oducts, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard.

22、oreword 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 process. In addition, it does not contain requirements nec
23、essary for conformance to the Standard. The Alliance for Telecommunication Industry Solutions (ATIS) serves the public through improved understanding between carriers, customers, and manufacturers. The Telecom Management and Operations Committee (TMOC) - formerly T1M1 -develops operations, administr
24、ation, maintenance and provisioning standards, and other documentation related to Operations Support System (OSS) and Network Element (NE) functions and interfaces for communications networks - with an emphasis on standards development related to U.S.A. communication networks in coordination with th
25、e development of international standards. 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 fo
26、r the same criterion, the recommendation represents a goal currently identifiable as having distinct compatibility or performance advantages. Suggestions for improvement of this document are welcome. They should be sent to the Alliance for Telecommunications Industry Solutions, TMOC Secretariat, 120

32、ent is intended for use as the North American standard for mapping measurements made with In-Service, Non-intrusive Measurement Devices (INMDs) to the parameters used in customer opinion models for voice services. This standard includes mathematical algorithms which perform this mapping and allow cu
33、stomer opinion ratings to be determined from INMD measurements. This will allow INMD measurements to be used to evaluate the performance of telecommunications connections and services and to detect speech level, noise, and echo anomalies on telecommunications connections. Although other impairments
34、affect voice transmission, only loss, noise, and echo are studied here. The algorithms specified here are applicable to metallic loop systems terminated in modern electronic telephones, as well as other equivalent network connections and terminal equipment. It is the intention of this standard to us
35、e and align with the relevant ITU-T Recommendation. This alignment effort consists of adopting ITU-T Recommendation P.562. 2 NORMATIVE REFERENCES The following standards contain provisions which, through reference in this text, constitute provisions of this American National Standard. At the time of
36、 publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this American National Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
