Summary

Recommendation ITU-T J.196.3 describes the media access control (MAC) layer specification of second generation high performance network over coax (HiNoC) which provides 1 Gbit/s data transmission over coaxial networks. HiNoC consists of a HiNoC bridge (HB) and HiNoC modem (HM) as architectural functional entities and is layered as MAC layer and physical (PHY) layer. HiNoC 2.0 uses time division duplexing (TDD) to adjust the bandwidth for upstream and downstream feasibly. HiNoC 2.0 uses time division multiple access (TDMA) and optional orthogonal frequency‑division multiple access (OFDMA). The HiNoC 2.0 MAC (HiMAC) layer is composed of the convergence sublayer (CS), the common part sublayer (CPS) and the security sublayer (SS). This Recommendation contains descriptions for HiMAC frame types, functions and mechanisms of CS and CPS.
