This Recommendation specifies the interoperability and compatibility for G.9954v2 stations. The requirements are written from the perspective of a compliant transmitter, although some minimum performance requirements are established for receivers. This Recommendation does not specify implementation. A G.9954v2 station at a minimum shall be capable of transmitting and receiving over phoneline or over coax. The structure of this Recommendation is as follows: Clause 6: PHY layer specification over phoneline – This clause specifies the G.9954v2 PHY layer specification over phoneline. Clause 7: PHY layer specification over coax – This clause specifies the G.9954v2 PHY layer specification over coax. Clause 8: Media access protocol specification – This clause specifies the G.9954v2 media access protocol. Clause 9: Compatibility specification – This clause describes the method by which backwards compatibility, coexistence and interoperability with G.9954 nodes is achieved in a mixed network of G.9954v2 and G.9954v1 nodes. Clause 10: Quality of service – This clause describes the G.9954v2 quality of service framework. Clause 11: Link-layer protocol specification – This clause specifies the required link layer control functionalities.
