This Recommendation specifies the physical layer management for ADSL and VDSL2 transmission
systems based on the usage of indicator bits and EOC messages defined in the G.992.x series of
ITU-T Recommendations and in ITU-T Rec. G.993.2, and the clear embedded operation channel
defined in this Recommendation.
It specifies Network Management elements content for configuration, fault and performance
management.
The mechanisms to provide 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 – transmission path level.
For interrelationships of this Recommendation with other G.99x-series ITU-T Recommendations,
see ITU-T Rec. G.995.1.
