Recommendation ITU-T G.8012/Y.1308 specifies the Ethernet user-to-network interface (UNI) and the Ethernet network node interface (NNI).

This Recommendation specifies the Ethernet UNI and the Ethernet NNI, where the Ethernet UNI is formed by an Ethernet interface and the Ethernet NNI by an Ethernet interface or an Ethernet over transport interface.
