Frame Relay Network Interworking (FRF.5)
Frame Relay Networking Interworking (FRF.5) is a conversion mechanism by which Frame Relay networks
can communicate with ATM networks and the conversion is not visible to the Frame Relay side of the net
-
work. On the ATM side of the network, the ATM device must support the Frame Relay Service Specific Con-
vergence Sublayer (FR-SSCS). The Patton Electronics Model 3086 support all of the required Inter-Working
Functions that are required to supply a Frame Relay Network Interworking function.
The Frame Relay Network Interworking functions are defined by the Frame Relay Forum specification “Frame
Relay/ATM PVC Network Interworking Implementation Agreement FRF.5”
FRN Configuration Options
The Frame Relay Network Interworking functions on the Patton Electronics Model 3086 are defined by both
ports and channels. Ports are used to define the lower level Interworking Functions. First a port must be cre
-
ated that defines such items as the ATM VPI/VCI and the type of mapping that will be used to make the con-
nection. Once the port is created, channels can be attached to the ports that will allow data channels to pass
from the Frame Relay interface to the ATM interface. Channel configuration variables options include the
Frame Relay DLCI that will be used to communicate with the Frame Relay Network.
