Frame Relay-to-ATM Transparent Service Interworking Connections
A Frame Relay-to-ATM Transparent Service Interworking (ATFT) connection is configured as a
VBR connection with a number of the ATM and Frame Relay connection parameters being mapped
between each side of the connection..
The parameters for an ATFT connection are shown in Figure 21-16 in the sequence in which they occur
during the execution of the addcon command.
