In this example, a call comes in to Catalyst 4224 1 on the BRI port. The DID
information allows the Catalyst 4224 to route the call based on the called number.
If the called number is 2xxx, the call is routed to Catalyst 4224 2000; if the called
number is 3xxx, the call is routed to Catalyst 4224 3000.
Figure 5-1 illustrates the topology of this connection example.
