DESCRIPTION
"This object describes which mode of translation

mapping in the frame relay to ATM direction.
mode1(1) = The FECN field in the Q.922 core frame
shall be mapped to the ATM EFCI field
of every cell generated by the
segmentation process of the AAL5 PDU
containing the information of that
frame.
mode2(2) = The FECN field in the Q.922 core frame
shall not be mapped to the ATM EFCI
field of cells generated by the
segmentation process of the AAL5 PDU
containing the information of that
frame. The EFCI field is always set to
'congestion not experienced'.
In both of the modes above, if there is congestion
in the forward direction in the ATM layer within
the IWF, then the IWF can set the EFCI field to
'congestion experienced'."

DESCRIPTION
"This object contains the index value of the
FR/ATM cross-connect table entry used to link the
ATM VCL with a frame relay PVC.
Each row of the atmVclTable that is not cross-
connected with a frame relay PVC MUST return the
value zero when this object is read.
In the case of (frame relay) point to (ATM)
multipoint, multiple ATM VCLs will have the same
value of this object, and all their cross-
connections are identified by entries that are
indexed by the same value of
frAtmIwfVclCrossConnectIdentifier in the
frAtmIwfConnectionTable of this MIB module.
The value of this object is initialized by the
agent after the associated entries in the
frAtmIwfConnectionTable have been created."
