2.5 Topologies

Depending upon the number of ports on the AI, the AI can be

used as either a repeater, link or hub. The AI2 has only two

ports and, therefore, can be used as a repeater or link while the

AI3 has three ports and can be used as a hub.

2.5.1 Repeater

The repeater extends wiring segments of the same type of cable.

Coaxial cable or twisted-pair segments can be extended using

repeaters.
