The router supports Broadband Remote Access Server (B-RAS) applications, as shown
in Figure 2 on page 6. In this application, the router handles the aggregated output from
the digital subscriber line access multiplexers (DSLAMs). Directly connected to the
subscriber premises, the DSLAMs handle the copper termination and aggregate the traffic
into a higher-speed uplink. The output from the DSLAM is fed into the router through a
DS3 or OC3 link.
