Figure 1-1 shows a typical ATM-to-LAN topology. Two Catalyst 2900 series switches are
connected to other ATM-supported devices through the ATM modules. The link between
the LightStream 1010 ATM switch and the other devices provides 155 Mbps of bandwidth
over a 2-kilometer MM fiber-optic cable, 15-kilometer medium-reach SM fiber-optic cable,
40-kilometer long-reach SM fiber-optic cable, or 100-meter UTP cable.
