Summary

Recommendation ITU-T G.8012/Y.1308 specifies the Ethernet user-to-network interface (UNI) and the Ethernet network node interface (NNI). First, a set of physical Ethernet interfaces is defined for the Ethernet UNI and the Ethernet NNI. Further on, an Ethernet over transport interface is defined for the Ethernet NNI. The Ethernet over transport NNI uses the optical transport hierarchy (OTH) server layer network.

This edition of the Recommendation supersedes Recommendation ITU-T G.8012.1/Y.1308.1 (2012), and together with Recommendation ITU-T G.8021/Y.1341, supersedes Recommendation ITU-T G.8021.1/Y.1341.1 (2012).

This edition also removes items formerly considered for further study and incorporates terms formerly defined in Recommendations ITU-T G.8001/Y.1354 (04/2016) and ITU-T G.8101/Y.1355 (11/2016).
