| A network's performance is closely related to good connections.
Therefore, the focus of this chapter is standards for networking media. These standards are developed and issued
by the Institute of Electrical and Electronic Engineers
(IEEE), the Underwriters Laboratories (UL), the Telecommunications Industry Association
(TIA) and the Electrical Industries Association (EIA). The latter two organizations
jointly issue a list of standards, and frequently you see them listed as the
TIA/EIA
standards. In addition to these groups and organizations, local, state, county, and
national government agencies issue specifications and requirements that can affect the
type of cable used in a LAN. In
this chapter, you will learn how to use appropriate and recommended
techniques for dressing and securing the cable. Included in this will
be the use of cable ties, cable support bars, wire management panels,
and releasable Velcro straps. You will learn that when RJ-45 jacks are used at the
telecommunications outlet in a horizontal cabling scheme, the wiring sequence is critical
for optimal network performance. A wiring closet serves as the center point of a star topology for the wiring and wiring equipment used for connecting devices in a network. With this in mind, you will learn how a wiring closet should be designed for wiring a data or voice network.
Lastly, you will learn about the equipment found in a
wiring closet can include patch panels, wiring hubs, bridges, switches, and routers.
| Note: In this
chapter, you may need to convert units of measurements. A
small utility to help you make the conversions is
available here.
