Perform the following tasks in a prescribed order before configuring a Frame Relay to ATM interworking 
permanent virtual channel (PVC):

Configure the controller on the Frame Relay port adapter.

Configure the T1 channel or E1 interface and channel group on the Frame Relay port adapter.

Configure Frame Relay encapsulation and Frame Relay LMI on the serial port corresponding to the 
channel group configured in Step 2.

Configure Frame Relay resource management tasks including Frame Relay connection traffic table rows.

Configure Frame Relay to ATM interworking VC tasks.

This section describes configuring Frame Relay to ATM network interworking PVCs. This type of 
connection establishes a bidirectional facility that transfers Frame Relay traffic between two Frame 
Relay users through an ATM network.

 shows an example of a Frame Relay to ATM network interworking PVC between Frame 

Relay User A and ATM User D through an ATM network.

To configure a Frame Relay to ATM network interworking PVC, perform the following steps, beginning 
in global configuration mode:
