4-port OC-3c/STM-1 ATM Line Card Overview
The 4-port OC-3c/STM-1 ATM line card interfaces with the switch fabric of the Cisco 12000 Series
Router. It provides four 155-Mbps OC-3c/STM-1c duplex SC single-mode or multimode SONET/SDH
connections. This connection is concatenated, which provides for increased efficiency by eliminating the
need to partition the bandwidth.
Figure 2 shows the single-mode, intermediate-range 4-port OC-3c/STM-1 ATM line card.

4-port OC-12c/STM-4c ATM Line Card Overview
The 4-port OC-12c/STM-4c ATM line card provides the Cisco 12000 Series Router with four 622-Mbps
ATM interfaces. The card interfaces to the router’s switch fabric and provides four OC-12c/STM-4c SC
connectors for duplex single-mode or multimode SONET/SDH connections.
Figure 3 illustrates the single-mode, intermediate-range 4-port OC-12c/STM-4c ATM line card. There
are four ports, numbered 0 to 3, on each line card. Each port has a set of status LEDs. Each SONET
connection is concatenated, which provides for increased efficiency by eliminating the need to partition
the bandwidth.
