Network Topologies
Standalone Topology
A standalone topology uses only one bridging converter between the end-
nodes. Figure 8 illustrates a standalone topology that uses two
AT-GS2002/SP bridging converters to interconnect three remote
campuses. Campus 1 has an AT-9424T/SP switch which provides a
connection of up to 15 kilometers (9.3 miles), are connected to two
AT-GS2002/SP bridging converters via their 1000Base SFP ports. The
10/100/1000Base-T twisted pair port on the first bridging converter is
connected to one of the twisted pair ports in the AT-8524M switch at
Campus 2; and the 10/100/1000Base-T twisted pair port on the second
bridging converter is connected to one of the twisted pair ports in the
AT-8524M switch at Campus 3.
