ATM-to-Frame Relay Network Interworking Connections
An ATM-to-Frame Relay (ATFR) 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 21-14 in the sequence in which they occur
during the execution of the addcon command.

Part A
Network interworking connection from CPE Frame Relay port
to CPE Frame Relay port across an ATM Network with the
interworking function performed by both ends of the network.
Part B
Network interworking connection from CPE Frame Relay port
to CPE ATM port across an ATM network, where the network
performs an interworking function only at the Frame Relay end
of the network. The CPE receiving and transmitting ATM cells at
its ATM port is responsible for exercising the applicable service
specific convergence sublayer, in this case, (FR-SSCS).
