ITU-T X.85/Y.1321 (2001)/Amd.2 (01/2009) i Recommendation ITU-T X.85/Y.1321 IP over SDH using LAPS Amendment 2 Additional SAPI values for encapsulated protocols Summary Amendment 2 to Recommendation ITU-T X.85/Y.1321 adds a set of new SAPI values for LAPS to Table A.1, to identify
9、 the encapsulated protocols. Most of the values contained in the new table come from IETF-assigned PPP DLL Protocol Numbers due to the LAPS compatibility with PPP/HDLC. Source Amendment 2 to Recommendation ITU-T X.85/Y.1321 (2001) was approved on 13 January 2009 by ITU-T Study Group 15 (2009-2012) u
10、nder Recommendation ITU-T A.8 procedures. ii Rec. ITU-T X.85/Y.1321 (2001)/Amd.2 (01/2009) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunicatio
11、n Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WT
12、SA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall
13、within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Reco
14、mmendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such
15、 as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommend
16、ation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approva
17、l of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB pat
