If you have more than three AT-FS705E FC or AT-FS706E FC switches that

you want to connect together, then you might use an 100Base Ethernet switch

that has multiple fiber optic ports to act as a backbone switch. This switch will

function as the connection focal point for all the AT-FS705E FC and AT-

FS706E FC switches in your network. This is often referred to as a collapsed

backbone. An example of this topology is illustrated in Figure 6. Five

AT-FS705 Ethernet Switches have been interconnected using an AT-8216FXL

Fast Ethernet Switch.
