Recommendation ITU-T G.798 specifies both the components and the methodology that should be used in order to specify the optical transport network (OTN) functionality of network elements; it does not specify individual optical transport network equipment.
Amendment 1 contains text modifications and additions for:
-moving the ODUkP to Ethernet MAC layer and Ethernet Reconciliation sublayer adaptation functions from ITU-T G.8021 to ITU-T G.798.
-supporting the adaptation of ODUkP to Ethernet Coding sublayer for 25 Gb/s, 200 Gb/s and 400 Gb/s Ethernet signals.
- alignment with ITU-T G.8023.
- replacing Appendix VIII to align with ITU-T G.872 and ITU-T G.873.1
Amendment 2 contains text modifications and additions for:
-OTSi to OTU4 adaptation function with SC FEC.
-OTSi to FlexO-1-SC adaptation function.
-alignment with ITU-T G.709.1.
Amendment 3 contains text modifications and additions for:
-supporting 25 Gb/s and 50 Gb/s OTN interfaces.
-supporting 200 Gb/s and 400 Gb/s FlexO interfaces.
-supporting the adaptation of ODUkP to Ethernet Coding sublayer for 50 Gb/s Ethernet signals.
-supporting the adaptation of ODUkP to SDI/1.5G SDI signals.
-alignment with ITU-T G.709.1 and ITU-T G.709.3.
