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 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 the in-premises wiring.

Additionally, this Recommendation provides for spectrum notching for compatibility with amateur radio services.
