scope:
This Recommendation specifies the system architecture and functionality for all components of the physical (PHY) layer of home network transceivers designed for the transmission of data over premises' wiring, including inside telephone wiring, coaxial cable, power-line wiring, plastic optical fibres, and any combinations of these.
Specifically, this Recommendation defines:
• the home network architecture and reference models
• the physical layer specification (PCS, PMA and PMD).
These transceivers are intended to be compatible with other devices sharing in-premises wiring.
Additionally, this Recommendation provides for spectrum notching for compatibility with amateur radio services.
Corrigendum 1 aligns the reserved bits allocations within ITU-T G.99xx Recommendations
Amendment 1 includes the extension of the Recommendation to operate with non-band limited operational frequency bands (OFBs) over coaxial and phoneline mediums.
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 medium access plan (MAP) to better control power spectral density (PSD) levels in complex networks such as those for smart grid applications.
Corrigendum 2 corrects the duration of MSG, BMSG and BACK frames, corrects a test vector in clause G.4.1, and reserves PROBE frame and BACK PHY-frame type field values for use by ITU-T G.9963.
