Summary

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.
