5、ANDARD 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 agree
6、ment 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 use of A

Abstract This standard provides loss plan requireme
20、nts for digital networks, including Digital End Offices, taking into account different network configurations and elements, and their associated transmission characteristics. ATIS-0100508.2003 ii Foreword The information contained in this Foreword is not part of this American National Standard (ANS)
21、 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 necessary for conformance to the standard. This document is ent
22、itled Loss Plan for Digital Networks. This standard provides transmission recommendations for connections between network interfaces (NIs) that are all digital (NI-to-NI), or that are all digital from digital end office-to-digital end office) with digital or analog access lines from appropriate end-
23、user terminals or interconnecting networks. Footnotes are not officially part of this standard. This standard contains annexes that are for information only and are not considered part of the Standard. Future control of this document will reside with Accredited Standards Committee Telecommunications
24、, T1. This control of additions to the specification - such as protocol evolution, new applications, and operational requirements - will permit compatibility among U.S. networks. Such additions will be incorporated in an orderly manner with due consideration to the ITU-T layered model principles, co
25、nventions, and functional boundaries. Suggestions for improvement of this standard will be welcome. These should be sent to the Alliance for Telecommunications Industry Solutions, T1 Secretariat, 1200 G Street, NW, Suite 500, Washington DC 20005. This standard was processed and approved for submitta
26、l to ANSI by the Accredited Standards Committee Telecommunications, T1. Committee approval of this standard does not necessarily imply that all committee members voted for its approval.
