Summary

Recommendation ITU-T J.198.3 defines the medium access control (MAC) layer specification of third generation high performance network over coax (HiNoC 3.0), which provides 10 Gbit/s data transmission over coaxial networks in the cable industry. HiNoC consists of HiNoC bridge (HB) and HiNoC modem (HM) in terms of architectural functional entities, and is layered into medium access control (MAC) layer and physical (PHY) layer.

HiNoC 3.0 MAC layer selects the time division duplexing (TDD) mode to adjust the bandwidth for upstream and downstream feasibly. HiNoC 3.0 MAC layer adopts time division multiple access (TDMA) and optional orthogonal frequency division multiple access (OFDMA). HiNoC 3.0 MAC layer supports the channel bonding mechanism. The HiNoC 3.0 MAC layer is composed of the convergence sublayer (CS), the common part sublayer (CPS) and the optional security sublayer (SS).

This Recommendation contains descriptions for HiNoC 3.0 MAC frame types, functions and mechanisms of CS and CPS.
