ITU-T Recommendations

Recommendation ITU-T G.997.1 specifies the physical layer management for asymmetric digital subscriber line (ADSL) and very high speed digital subscriber line 2 (VDSL2) transmission systems. It specifies means of communication on a transport transmission channel defined in the physical layer Recommendations ITU-T G.992.1, ITU-T G.992.2, ITU-T G.992.3, ITU-T G.992.4, ITU‑T G.992.5 and ITU-T G.993.2. It specifies network elements (NE) content and syntax for configuration, fault and performance management.

The revision of this Recommendation includes the management information base (MIB) elements for the physical layer management of Recommendation ITU‑T G.993.2 and additional MIB elements for the physical layer management of Recommendations ITU‑T G.992.3 and ITU-T G.992.5.

The 2016 edition of this Recommendation integrates ITU-T G.997.1 (2012) and all its amendments and corrigenda; it did not add any new technical material.

Amendment 1 includes:

– Management parameters for the support of G.993.5 Annex B (Vectored Long Reach VDSL) and ITU-T G.993.2 Annex D (Unvectored Long Reach VDSL)

– Management parameters for the support of G.993.5 Annex A (Mitigating strong FEXT)

– Add missing parameter INM_INPEQ_FORMAT for the support of INM in ITU-T G.993.2.
