Chapter 3.
Network Planning
This chapter discusses a range of topics that are important in network planning.
The topics are arranged approximately in the order they should be considered or
performed. Even if the Quick Start meets your immediate needs, you can read
this chapter to get an overview of the details involved in planning a network.
Every network offers unique constraints and requirements. If you plan to install a
small network with a few devices in one room, you may find this chapter has all
the information you need. If you plan to implement a large network with
hundreds of devices, this chapter may serve only as a starting point. You may
consider investing in a consultant to help you design your network.
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). This standard (IEEE
802.3) defines how Ethernet components interact with each other on Local Area
Networks (LANs) constructed of unshielded twisted-pair telephone wire.
Twisted-pair wiring provides reliable communication between network devices
located up to 100 meters (328 feet) from the communications hub.
10BaseT, the latest development in Ethernet communications, represents a
tremendous leap in networking technology. 10BaseT is economical because it
uses regular twisted-pair telephone wire. It is easy to install because it uses
cabling similar to that used in a standard telephone system which is installed in
most buildings.
Unlike thick and thin networks, in which devices are connected in a linear or
"bus" configuration, 10BaseT networks are arranged in a star configuration, in
which network devices are connected at a central hub, like the spokes of a
wheel. The star configuration is more reliable because each "spoke" operates
independently of other network components. When multiple hubs are used, the
network is called a tree, or hierarchical star, and has the same advantages.
