This Recommendation describes the management requirements and the information model for network elements (NEs) that contain optical media layer functions defined by ITU-T equipment Recommendations based on the ITU-T G.807 architecture, e.g., [ITU-T G.798].

The management requirements are based on [ITU-T G.7710], and the information model (IM) is based on ITU-T G.7711 object classes. Being based on the common IM in [ITU-T G.7711], the information model for the optical media layer can provide consistent operation, administration, maintenance and provisioning of transport networks.

The management of the optical media layer is independent of the digital clients carried across the media network.

This first version of ITU-T G.876 provides only the optical media layer management requirements and information models for the optical transport network (OTN). Other optical media network layer uses can be added in future versions of this Recommendation.
