Caution: Regulations regarding the connection of equipment to telephone networks vary from country to country. Check with your local telephone network supplier before using existing telephone wiring.

An Ethernet twisted-pair link segment requires two pairs of wires—Category 3, 4 or 5 for 10 Mbps connections and Category 5 for 100 Mbps connections. Each wire pair is identi- fied by two different colors. For example, one wire might be brown and the other, brown with white stripes.

Caution: Each wire pair must be attached to the RJ-45 connec- tors in a specific orientation. (See “Twisted-Pair Cabling Guidelines” in Chapter 3 for an explanation.)

Each twisted-pair link segment must have an RJ-45 connector attached to both ends. According to the IEEE specifications, pins 1 and 2 are used for transmitting data, and pins 3 and 6 for receiving data.
