Configuring Frame Relay to ATM Virtual Connections
Characteristics and Types of Virtual Connections
The characteristics of the Frame Relay to ATM interworking VC, established when the VC is created,
include the following:
Frame Relay to ATM interworking parameters
Committed information rate (CIR), committed burst size (Bc), excess burst size (Be), peak
information rate (PIR) (that is, access rate [AR]) for Frame Relay
Peak and average transmission rates for ATM
Service category
Cell sequencing integrity
ATM adaption Layer 5 (AAL5) for terminating interworking PVC
These switching features can be turned off with the interface configuration commands.
Note For information about ATM VCCs, see Chapter 7, “Configuring Virtual Connections.”
Note You can configure a maximum of 2000 virtual connections on a CDS3 or CE1 Frame Relay port adapter.
Table20-4 lists the type s of supported virtual connections.
