1、 AMERICAN NATIONAL STANDARD FOR TELECOMMUNICATIONS ATIS-0900105.2015 Synchronous Optical Network (SONET) Basic Description including Multiplex Structure, Rates, and Formats As a leading technology and solutions development organization, the Alliance for Telecommunications Industry Solutions (ATIS) b
2、rings together the top global ICT companies to advance the industrys most pressing business priorities. ATIS nearly 200 member companies are currently working to address the All-IP transition, network functions virtualization, big data analytics, cloud services, device solutions, emergency services,
3、 M2M, cyber security, network evolution, quality of service, billing support, operations, and much more. These priorities follow a fast-track development lifecycle from design and innovation through standards, specifications, requirements, business use cases, software toolkits, open source solutions
4、, and interoperability testing. ATIS is accredited by the American National Standards Institute (ANSI). The organization is the North American Organizational Partner for the 3rd Generation Partnership Project (3GPP), a founding Partner of the oneM2M global initiative, a member of and major U.S. cont
5、ributor to the International Telecommunication Union (ITU), as well as a member of the Inter-American Telecommunication Commission (CITEL). For more information, visit www.atis.org. AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements for
6、 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 and materially affected interests. Substantial agreement means m
7、uch 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 American National Standards is completely voluntary; their existence does not in any respect preclu
8、de 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 National Standards Institute does not develop standards and will in no circumstances give an interpretation of
9、 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 Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appea
10、rs 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 that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American
11、 National Standards may receive current information on all standards by calling or writing the American National Standards Institute.

15、ecommendation. 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 criterion, the recommendation represents a goal currently identifiable as having distinct compatibilit
16、y or performance advantages. This standard has 2 annexes. One is normative and is part of the standard; that is, this annex includes requirements that are a part of the specifications of this standard. One is informative and is not considered part of this standard; that is, this annex does not inclu
17、de requirements for the interface, but provides information about the interface specified. This standard is technically consistent with work in ITU-T on the Network Node Interface (NNI) using synchronous multiplexing techniques, and is compatible with ITU-T Recommendations G.707, G.783, and G.784 Sy

They should be sent to the Alliance for Telecommunications Industry Solutions, COAST, 1200 G Street NW, Suite 500, Washington, DC 20005. At the time of consensus on this document, COAST, which was responsibl
19、e for its development, had the following leadership: K. Biholar, COAST Chair (Alcatel-Lucent) W.

34、ure, Rates, and Formats 1 1 Scope This document is the baseline of a series of standards that define a modular family of rates and formats available for use in interfaces generally referred to as SONET. This series of documents is identified by the ATIS-0900105 prefix. This document (ATIS-0900105) d
35、escribes a base rate and format along with a multiplexing scheme. Other characteristics described in this standard are: layering of overhead, definitions of function and position of overhead, frequency justification, scrambling, conditions for setting overhead values, and a standardized set of paylo
36、ad-carrying envelopes. As an aid to the reader, a mapping is provided between SONET and SDH terminology. Any differences between the SDH and SONET specifications at the time of approval of this standard that affect interworking are highlighted. The differences are relative to the SDH Recommendations
37、 under review in SG 15 at that time. Other ATIS-0900105.xx standards are listed in clause 2 and describe such items as payload mappings, protection switching, data communications interfaces, tandem connection, and physical layer specifications. 2 Normative References The following standards contain
