FRF.5 Frame Relay-ATM Network Interworking
This section compares the networking standards defined in Frame Relay Forum document number FRF.5, Frame Relay/ATM PVC Network Interworking Implementation Agreement, with those defined for the Cisco FRF.5 Frame Relay-to-ATM Network Interworking feature.
The following sections and subsections in this implementation agreement are supported as follows:
4.1 Frame Formatting and Delimiting: Only the default (2 octet) address field is supported.
4.3 Connection Multiplexing: Mapping one-to-one connections between a Frame Relay data-link connection identifier (DLCI) and Frame Relay service specific convergence sublayer (SSCS) DLCI is done using the default DLCI value of 1022. Mapping many-to-one connections from Frame Relay DLCI to Frame Relay-SSCS DLCI and vice versa is user-configured (and it must be agreed upon between the two ATM end systems).
18.104.22.168 Frame Relay to B-ISDN Direction: Backward congestion indication is not supported.
5.1 Traffic Management: There is no direct mapping between Frame Relay and ATM traffic parameters; these parameters are configured independently.
5.2 PVC Management: PVC management is not supported.
5.3 Description of Upper Layer User Protocol Encapsulation Methods: This section applies only to terminal equipment and is not supported.
5.4.1 Operations for the Common Part of the AAL Type 5: The error counters mentioned in this section are reset at startup, and are counted until they are reset.

FRF.8 Frame Relay-ATM Service Interworking
This section compares the networking standards defined in Frame Relay Forum Document Number FRF.8, Frame Relay/ATM PVC Service Interworking Implementation Agreement, with those defined for the Cisco FRF.8 Frame Relay-to-ATM Service Interworking feature.
The following sections and subsections in the FRF.8 agreement are supported as follows:
5.1 Traffic Management: There is no direct mapping between the Frame Relay and ATM traffic parameters; these parameters are configured independently.
5.2 Frame Relay PVC Management Procedures: Procedures for the asynchronous status message defined in Q.933 annex A are not supported.
22.214.171.124 Fragmentation and Reassembly: Fragmentation and reassembly are not supported.
5.4 Address Resolution: The IP and IPX protocols are supported.
6.0 Operations for the Common Part of the AAL Type 5: The error counters mentioned in this section are reset at startup, and are counted until they are reset.
