Layer examples for TR-512 v1.3.1	Xiang	For TR-512.A.5 v1.3.1 Circuit Switched examples Circuit Switched (L1 & L2) Examples TR-512.A.5_v1.3.1_xy01_OnfCoreIm-Appendix-CircuitSwitchedExamples-L2-L3-gd was presented Comments: Need cover notes Suggested to look at Figure 57 in SD1-18. This shows the Tributary side port on the left and the line side on the right. Notice the reversal of the stack order on the left as it moves from the optical section extracting the Digital Signal and then re-multiplexing into the OCh Also to look at Figure 13 (case B) & Figure 15 (CTP type F) in SD1-18 Follow the color convention in the Key diagram in TR-512.1 Add text to explain the figures Keep the Trapezoids same size Need to add to TR-512.4 to show termination of a FC on an LTP with encapsulated forwarding function For TR-512.A.6 v1.3.1 Packet Switched examples (not discussed) TR-512.A.6_v1.3.1_xy02_OnfCoreIm-Appendix-PacketSwitchedExamples-L2-L3-gd onf2017.202.04.XY_LayerExamples20171023
G.8052.1 and IEEE 802 Ethernet OAM	Kam	The following was prepared for the call but not discussed due to running out of time. It is deferred for Thursday slot IM-F Touch Point Consideration for the ITU-T G.8052.1 and IEEE 802 OAM models The G.8052 MepSource, MepSink, MepBidirectional, ETH_TTPSource/Sink, and ETH_CTPSource/Sink be the touch point classes from the G.8052.1 side with the IEEE classes The CFM “component” and “mep” classes be used as the touch point classes from the IEEE CFM model with the G.8052.1 model. Possible approaches for linking the touch point classes Spec approach: The G.8052.1 Mep and ETH TTP/CTP decorate/specify the IEEE MEP and Component classes, as illustrated below Subclassing approach: The G.8052.1 Mep and ETH TTP/CTP are subclassed from IEEE MEP and Component as illustrated below. Referencing approach: The G.8052.1 Mep and ETH TTP/CTP point to the IEEE MEP and Component for the needed properties as illustrated below
Re-engineering of IEEE 802 OAM YANG	Bernd	This topic was not discussed due to running out of time. It is deferred for Thursday slot IM-F
