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.
