This Foundation Recommendation specifies basic characteristics of next generation home networking transceivers capable of operating over premises wiring including inside telephone wiring, coaxial cable, and power line wiring, and combinations of these, at data rates up to 1 gigabit/second. The specification includes a description of the home network architecture and reference models along with major aspects of the transceiver physical layer specification. A future version of this Recommendation will include the data link layer and regional Annexes to complete the transceiver specification.

The title of ITU-T G.9960 was changed by SG15 on 1 December 2010 from "Next generation home networking transceivers" to "Unified high-speed wire-line based home networking transceivers – System architecture and PHY layer specification"
