Translation Mode
The Translation Mode variable defines the encapsulation mechanism that will be required to convert the ATM cells
(encapsulated per RFC2684) to the Frame Relay packets (encapsulated per RFC1490) and back. This is required
because ATM and Frame Relay encapsulate packets in different formats as defined by their respective RFC. There
are two options available for the Translation Mode setting within the Model 3086FR as defined below:
• Translate : When the connection channel is set to translate, the IWF converts between Frame Relay encap-
sulated frame and the ATM encapsulated cells. This conversion is performed by inspecting each frame/cell
and determining the PID (Protocol Identification) field within the packet. (Using this information, the
frame/cell is routed through an encapsulation conversion utility that creates the encapsulation required for
the destination network.) The Model 3086FR supports all 22 protocol types as defined by the FRF.8.1
