DESCRIPTION
"This object counts the number of frames discarded
by the IWF because, while operating in Translation

frame payload header according to the mapping
rules. (i.e., payload header not recognized by the
IWF).
Frame relay frames are received in the frame relay
to ATM direction of the PVC.
When operating in Transparent Mode, the IWF MUST
return noSuchInstance."

DESCRIPTION
"This object contains an appropriate value to be
used for frAtmIwfConnectionDescriptorIndex when
creating entries in the
