¿µ¹®³»¿ë¿ä¾à This standard describes the functional architecture of the optical transport network (OTN) using the modelling methodology described in Recommendations ITU-T G.800, ITU-T G.805 and ITU-T G.807. The OTN functionality is described from a network level viewpoint, taking into account, the characteristic information of clients of OTN, client/server layer associations, networking topology, layer network functionality, and optical media network structure. This standard describes the media portion of the network in terms of media constructs, media elements and optical signal maintenance entities. This amendment adds a description of the OTU25 and OTU50 interfaces, and enhances the description of flexible OTN interfaces.
