Traffic is translated by a protocol converter that provides communication betweendissimilar Frame Relay and ATM equipment. Figure 36 illustrates this concept.Figure 36Frame Relay-to-ATM Service Interworking (FRF.8)Frame Relayend stationFrame RelayPVCFRF.8interworkingfunctionATMPVCATMend station41439FRF.8 describes a one-to-one mapping between a Frame Relay and an ATM PVC.The FRF.8 standard is defined by the Frame Relay Forum Document Number FRF.8: Frame Relay/ATMPVC Network Service Interworking Implementation Agreement. For more information about whichsections of this implementation agreement are supported, see the appendix “Frame Relay-ATMInterworking Supported Standards” in this book.NoteOn Cisco 7200 series routers, Frame Relay-ATM interworking does not support congestion managementbit mapping.5
