SummaryThis amendment is the first amendment to the integrated ITU‑T Rec. G.992.3 approved in January 2005. It specifies the following additions: 1) Additions to clause 7 and Annex K for new optional valid S and D values in the PMS-TC framer configuration. This allows the achievement of higher net data rates while satisfying a configured minimum impulse noise protection (INP_min); 2) Addition to 8.13.2.4 for warm handshake. This defines default values for some configuration parameters, when not explicitly exchanged in the G.994.1 (handshake) phase of initialization; 3) Additions to Annex K to include new INP_min values. This allows a finer granularity for configuration of the minimum impulse noise protection (INP_min) and allows an optimization of related net data rates; 4) Additions to the PTM‑TC Annex K.3 to support 64/65-octet packet encapsulation (as defined in new Annex N) in addition to HDLC packet encapsulation; 5) A new Annex N defining the 64/65-octet packet encapsulation. The 64/65-octet encapsulation is defined by the IEEE 802.3 Ethernet standard and is now also included in the ITU-T DSL Recommendations; 6) A new Appendix VI defining the packet layer to physical layer logical interface. Revision marks are relative to the latest prepublished integrated version of ITU-T Rec. G.992.3. |
