5、TANDARD 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 agre
6、ement 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

This standard is part of the ANSI Tl .105 series of standards that were cre- ated when ANSI T1.1051991 was broken up into its constituent parts. This s
22、tandard specifies interface rates, formats, and transport overhead for SONET signals that are less than the STS-1 signal rate. Specifically, the VT15 and VT Group interfaces are addressed for transport of VT15 and VT Group payloads, respectively, across an interface. Other documents included in the
23、ANSI T1.105 series (at the time that this document was approved) are listed below. ANSI Tl .105-l 995 Telecommunications - Synchronous optical network (SONET) basic description including multiplex structure, rates, and formats ANSI Tl .105.01-l 995, Telecommunications - Synchronous optical net- work

26、ifications ANSI Tl .105.09-l 996, Telecommunications - Synchronous optical net- work (SONET) timing and synchronization Compliance with this standard should provide interoperability between NEs operating at the same rates defined with this standard, but the standard does not guarantee the compatibil
27、ity under all operating conditions. In some cases, location-oriented options are needed to ensure compatibility; this need for options is imposed by significant differences between net- work providers as well as between network elements. ANSI guidelines specify two categories of requirements: mandat
28、ory and advisory. The mandatory requirements are designated by the word “shall” and the advisory criteria by the word “should.” Mandatory requirements generally apply to rate and format requirements by specifying absolute, acceptable minimum functionality in those areas; advisory requirements genera
29、lly refer to optional features. There are two annexes in this standard. Both are informative and are not considered part of the standard. Suggestions for improvement of this standard are welcome. They should be sent to the Alliance for Telecommunications Industry Solutions, Suite 500, 1200 G Street,
30、 NW, Washington, DC 20005. This standard was processed and approved for submittal to ANSI by Accredited Standards Committee on Telecommunications, Tl. Committee approval of the standard does not necessarily imply that all committee members voted for its approval. At the time it approved this standar
