    Abstract - (Show below) - (Hide below)

    Gives the requirements for a local area network that utilizes the slotted ring access method, and that operates at 10 Mbits/second data rate. Defines the terms used in this part of ISO 8802, specifies the coding of bits and structure of slots and mini-packets, describes in general terms, the components of a configured slotted ring local area network in detail, the functional requirements for ring cable, ring connector sockets and ring continuity plugs; and the constraints on the size of, and the combination of components in, a configured SR-LAN. Some clauses specify in detail the functional requirements for the following components: free standing repeaters, nodes, monitors, logging stations and slave power supplies. Also gives details of Clause 11.
