ITU-T G.997.1 PDF

This Recommendation specifies the physical layer management for asymmetric digital subscriber line (ADSL) and very high speed digital subscriber line 2 (VDSL2) transmission systems based on the usage of indicator bits and embedded operations channel (EOC) messages specified in the ITU-T G.992.x series of Recommendations and in [ITU-T G.993.2], and the clear EOC specified in this Recommendation.

This Recommendation 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, 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 specifies only flow F3 – transmission path level.

For interrelationships of this Recommendation with other Recommendations of the ITU-T G.99x-series, see [ITU-T G.995.1].
