4.4.1–4.4.4: Table 26-1 identifies and defines common network cables.

Table 26-1. Common Network Cables

4.5.1: When you install the cabling for your network, it is important to follow cabling standards; these standards provide specifications for the installation and testing of cables. In addition, standards specify types of cables to use in specific environments, conductor materials, pinouts, wire sizes, shielding, cable lengths, connector types, and performance limits.

4.5.2: The following points define the standards for UTP cables:

• TIA/EIA defines the T568A and T568B wiring schemes for network cables. Be sure to use the same scheme for an entire installation project.

• A straight-through cable is wired with the same scheme on both ends, whereas a crossover cable is wired with T568A on one end and T568B on the other.
