Figure 30. BRS Super-Class Demonstration with BRS Super-Class
The reason voice quality remains good with IP traffic is because the BRS
Super-Class transfers voice traffic as urgent, and transfers other data only when
there is no voice traffic. Voice traffic can keep the constant bandwidth that is
necessary to keep voice quality as shown in Figure 31.

This is a sample of the new CREATE-SUPER-CLASS command. This new command
does not require you to define a percentage of bandwidth in reserve.
