PVC-group or interface can be
configured with different
service types.

the PVC.
transmit-priority value
By default, the transmission
priority is:
• 0 for UBR services.
• 5 for VBR-NRT services.
• 8 for VBR-RT services.
When you change the service
type for the PVC, the
transmission priority of the PVC
is restored to the default.
Configuring applications carried by ATM
As shown in Table 5, although ATM can carry multiple protocols, a specific encapsulation type might not
support ATM applications (such as IPoA, IPoEoA, PPPoA, and PPPoEoA).
