Summary

Recommendation ITU-T J.195.2 specifies the physical (PHY) layer specification for high‑speed data transmission over coaxial cable as part of the high performance network over coax (HiNoC). The HiNoC architecture consists of a HiNoC bridge (HB) and HiNoC modems (HMs), and the HiNoC protocol stack includes the media access control (MAC) layer and PHY layer. HiNoC utilizes the unassigned spectrum of the "last 100-meter" coaxial network to provide more bandwidth and improve spectral efficiency. This document contains descriptions for the signal transmission mode of the PHY layer, including frame structure, channel coding and modulation techniques.
