In practice, this scenario is done by creating two Service Configurations,
and using the same PVC for both.
6.1.1 Bandwidth Control
The bandwidth control in EDA is done in several layers:
1. The DSL layer by setting the overall bandwidth for the DSL connection
2. The ATM layer by setting the bandwidth for each PVC
3. The Ethernet layer by applying traffic policing
Figure 34 on page 44 illustrates an example of the bandwidth control
principle.
