Abstract Recommendation ITU-T G.9961 belongs to the family of ITU-T G.996x Recommendations. Recommendation ITU-T G.9961 specifies the data link layer (DLL) for wireline-based home networking transceivers capable of operating over premises wiring including inside telephone wiring, coaxial cable, and power-line wiring. It complements the system architecture and physical (PHY) layer specification in Recommendation ITU-T G.9960, and the power spectral density (PSD) specification in Recommendation ITU-T G.9964. Amendment 1 includes a new physical layer specification. This new physical layer provides new modulation mechanisms (e.g., multi level coding) and robust communication mode (RCM) and allows the system to be operated over an extended bandwidth for coaxial and phoneline mediums. Corrigendum 2 adds missing management message OPCODES for the Metrics Acquisition Protocol.
