This Recommendation specifies the physical layer management for ADSL and VDSL2 transmission systems based on the usage of indicator bits and embedded operations channel (EOC) messages defined in the ITU-T G.992.x series of ITU-T Recommendations and in [ITU-T G.993.2]@ and the clear embedded operations channel defined in this Recommendation. It specifies network management elements content for configuration@ fault and performance management. The mechanisms to provide operations@ administration and maintenance (OAM) functions and to generate OAM flows F1@ F2 and F3 will depend on the transport mechanism of the physical layer transmission system as well as on the supervision functions contained within the physical layer termination functions of equipment. This Recommendation only specifies flow F3 ?C transmission path level. For interrelationships of this Recommendation with other G.99x-series ITU-T Recommendations@ see [ITU-T G.995.1].
