FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (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 Telecommunication 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 of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE the expression "Administration" is used for conciseness to indicate both a In this Recommendation, telecommunication administration and a recognized operating 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" 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 practice 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 development 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 strongly urged to consult the TSB patent database at http://www.itu.int/ITU-T/ipr/.

删除[Bert Klaps]: OTM-nr/OTM-0 删除[Bert Klaps]: (see [ITU- T G.959.1]) Modify the text of clause 12.2.1.2 to reflect that the OCh_TT_Sk function is only present behind an OTM-n interface and not behind an OTM-nr or OTM-0 interface: Optical signal post-conditioning: Post-conditioning of the single wavelength signal might be required. The specific conditioning processes depend on the OTM-n interface type and are outside the scope of this Recommendation. The processes OA, DAc, DAa and PMDC, as defined in clause 8.11.2, are possible. Clause 12.2.2.1, OChr trail termination source function (OChr_TT_So) 2.4 Modify the text of clause 12.2.2.1 to reflect that the OChr_TT_So function is present behind an OTM- 0 or OTM-nr interface: Optical signal pre-conditioning: Pre-conditioning of the single wavelength optical signal might be required. The specific conditioning processes depend on the OTM-nr/OTM-0 interface type (see [ITU- T G.959.1]). The processes OA, DAc, DAa and PMDC, as defined in clause 8.11.2, are possible. Clause 12.2.2.2, OChr trail termination sink function (OChr_TT_Sk) 2.5 Modify the text of clause 12.2.2.2 to reflect that the OChr_TT_Sk function is present behind an OTM-0 or OTM-nr interface: Optical signal post-conditioning: Post-conditioning of the single wavelength signal might be required. The specific conditioning processes depend on the OTM-nr/OTM-0 interface type (see [ITU- T G.959.1]). The processes OA, DAc, DAa and PMDC, as defined in clause 8.11.2, are possible. Clause 14.2.1.2, ODUkP trail termination sink function (ODUkP_TT_Sk) 2.6 Add the following note to clarify the reported pN_delay value: Performance monitoring … pN_delay  nN_delay (  number of frames between the DMValue toggle event and the received DMp signal value toggle event) NOTE 5 – This count is triggered by the ODUkP_TT_Sk_MI_DMValue toggle event, which is equal to the ODUkP_TT_So_MI_DMValue toggle event. NOTE 6 – This value is a snapshot value. NOTE 7 – This value is invalid if a STAT field indicating AIS, OCI, LCK, LTC, or BDI is received during the measurement.
