¿µ¹® ³»¿ë¿ä¾à The standard defines the atomic functions that are part of the two synchronization layers, the synchronization distribution (SD) layer and the network synchronization (NS) layer. It also defines some atomic functions, part of the transport layer, which are related to synchronization. These functions describe the synchronization of SDH, Ethernet, and OTN NEs and how these NEs are involved in Network Synchronization. The amendment standard provides the following updates:
- Modification of OTN interface description and addition of FlexE and MTN interfaces in Clause 5
- Addition of FlexO, FlexE and MTNS to SD layer adaptation functions in Clause 8
- Addition of FlexO, FlexE and MTNS layer clock adaptation functions in Clause 9
- Addition of Annex B describing SyncPhy data sets for physical layer clocks
- Addition of ¡°Appendix VII Use cases of mixing SSM and eSSM¡±
- Change Title from ¡°Synchronization layer functions¡± to ¡°Synchronization layer functions for frequency synchronization based on the physical layer¡±
- Correction of Figure I.6 in Appendix I
