Summary:
|
Recommendation ITU-T G.9960 belongs to the family of ITU-T G.996x Recommendations. Recommendation ITU-T G.9960 specifies the system architecture and physical (PHY) layer for wireline-based home networking transceivers which are capable of operating over premises' wiring, including inside telephone wiring, coaxial cable, and power-line wiring. It complements the data link layer (DLL) specification in Recommendation ITU-T G.9961, and the power spectral density (PSD) specification in Recommendation ITU-T G.9964.
Amendment 1 includes the extension of the Recommendation to operate on an extended bandwidth over coaxial and phoneline mediums, multi-level coding and RCM schemes.
Amendment 2 includes a new Annex R on the use of reverse power feeding techniques for G.hn over coaxial media, and adds a field to the PHY frame header of the MAP to better control PSD levels in complex networks such as those for Smart Grid applications.
