  • Page 56: Overview

    This chapter discusses 10BaseT, introduces terms used in discussing network configurations, summarizes configuration guidelines for the 10Base media types supported by the AsantéHub 1012, and discusses wiring standards and site requirements for a 10BaseT network. About 10BaseT 10BaseT is a communications standard for twisted-pair Ethernet, defined by the Institute of Electrical and Electronic Engineers (IEEE).

  • Page 57: How 10Baset Uses Existing Telephone Wiring

    Chapter 3 How 10BaseT Uses Existing Telephone Wiring Buildings are usually wired for telephones in a star topology: wires run from one or more central locations, called wiring closets, to wall jacks in each office. A small building may have only one wiring closet; large buildings often have multiple wiring closets which are interconnected.

  • Page 58: Determine Application Needs

    Network Planning For small installations, the network manager’s duties may only require a few hours a week. For larger installations, the network manager’s position may be a full-time job. Determine Application Needs Think about how people on the network plan to use it. Will they be printing, exchanging mail, or transferring files steadily, or occasionally throughout the day? Will some users regularly access a multi-user database, transfer large graphics or CAD files, or launch applications from a server?

    Chapter 3 Common Network Configurations Single-Hub Star Network The simplest AsantéHub network consists of a single hub with attached devices (nodes). This configuration yields thirteen device ports, using the rear panel RJ- 45 IN port in addition to the twelve front-panel device ports. Only twisted-pair wiring is used.

  • Page 62: Backbone Network

    Network Planning • Reliability compared to the backbone network; if there is an accidental break in the wire, only service on the affected branch will be interrupted . Figure 3-3. Tree Network Backbone Network A backbone network suspends hubs from a linear length of cable, either thin or thick Ethernet cable.

  • Page 63: Figure 3-4. Thin Ethernet Backbone Network

    Chapter 3 • Simple topology, because all of the hubs are connected in a single line (the linear, or bus, configuration) • Better noise immunity because coaxial cable (either thick or thin) is shielded, vs. unshielded twisted-pair • Physical strength; coaxial cable is stronger than unshielded twisted-pair.
