ATFR Connections
An ATFR (ATM to Frame Relay) connection is a frame relay to ATM connection and 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 ATFR connection are shown in Figure 7-5 in the sequence in which they occur
during the execution of the addcon command.
