ITU-T G.783 (2006)/Amd.3 (02/2012) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technolog

12、ies (ICTs). The ITU Telecommunication 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 Telecommun

13、ication Standardization Assembly (WTSA), 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 o

14、f information technology which fall 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 operati

15、ng agency. Compliance with this Recommendation 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“

16、or some other obligatory language such 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 practi

17、ce or implementation of this Recommendation 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 developm

18、ent process. As of the date of approval of this Recommendation, ITU had 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 str

20、acteristics of synchronous digital hierarchy (SDH) equipment functional blocks Amendment 3 1) Scope This amendment contains modified text to be added to complete Recommendation ITU-T G.783 in respect of clarifying the jitter specification regarding transport over the optical transport network (OTN).

21、 2) Changes to Recommendation ITU-T G.783 (2006) 2.1) Clause 2 Add the following new references to clause 2. ITU-T G.798 Recommendation ITU-T G.798 (2010), Characteristics of optical transport network hierarchy equipment functional blocks. Replace reference 27 from Recommendation ITU-T G.783 (2006)

22、Amd. 1 (05/2008) with the following: ITU-T G.8251 Recommendation ITU-T G.8251 (2010), The control of jitter and wander within the optical transport network (OTN). 2.2) Clause 9.3.1.1 Add the following note under the title of clause 9.3.1.1. NOTE In the case where SDH RSN signals are transported over

23、 the OTN, the regenerator generation limits as given in this clause of Recommendation ITU-T G.783 do not apply. Instead, the specifications of ITU-T G.8251 are to be used. Here the jitter and wander transfer requirements for ODCp given in Annex A of ITU-T G.8251 ensure that the jitter due to the map

24、ping and de-mapping of client signals into and out of OPUk, possibly multiple times, will be acceptable and will satisfy the respective network limits of the SDH clients. The ODCp jitter generation requirements given in Annex A of ITU-T G.8251 ensure that any additional jitter produced by the ODCp w
