For the purpose of compatible interconnection of data processing equipment via a local area network (LAN) with the use of the HFC access method, this standard: 1) Gives a general description of the cable-tv LAN/MAN architecture. 2) Specifies the PDU formats (for downstream and upstream traffic. 3) Specifies the medium access control (MAC) protocol and data exchange sequence of the HeadEnd controller to station. 4) Specifies the medium access control protocols including finite-state machines and state tables that are specific to a downstream data flow.
