Summary

Recommendation ITU-T G.8112/Y.1371 specifies the interfaces for the multi-protocol label switching transport profile (MPLS-TP) layer network. The interfaces for the MPLS-TP layer network use various server layer networks, like the plesiochronous digital hierarchy (PDH), synchronous digital hierarchy (SDH), optical transport hierarchy (OTH) and the Ethernet MAC layer network (ETH).

Amendment 1 avoids redefining terms already defined in Recommendations ITU-T G.8001/Y.1354 and ITU‑T G.8101/Y.1355 by referencing these Recommendations.
