2.5.2 Link
A link converts one type of cabling segment into another. Using
two AIs in a link application, either a coaxial or twisted-pair
segment can be converted into a fiber segment.

2.5.3 Hub
With a three port AI, the hub (or star topology) configuration
can be implemented. AI3s can also be cascaded in order to
create a distributed star topology.

2.6 Connecting Cables to the AI
The AI provides either two or three ports preconfigured for
either coaxial, twisted-pair or fiber optic cable. More
information on designing an ARCNET cabling system can be
found in CC’s publication “ARCNET Tutorial Product Guide.”
Attach the coaxial, twisted-pair or fiber optic cables to the
devices that are being networked in the ARCNET LAN (refer
to Appendix A to verify that maximum cabling distance
specifications are not exceeded).
