Where the ERX System Fits In
Figure 1-5 and Figure 1-6 illustrate the position of the system as an edge
router in an end-to-end Internet network. Communications with the
system can take place over a variety of media. In Figure 1-5, the
customers are businesses using T1/T3 communication lines. In
Figure 1-6, the customers are using digital subscriber lines (DSLs) with a
DSL access multiplexer (DSLAM).
