 126                      PVC and one or more ATM PVCs, or an ATM PVC and

 143
 144                      After a frAtmIwfConnIndex is assigned for the

 147                      connection between the frame relay PVC and an ATM
 148                      PVC. In the case of `point-to-multipoint'

 150                      frAtmIwfConnIndex value and MUST refer to the same
 151                      frame relay PVC or ATM PVC respectively.  An entry
 152                      can be created only when at least one pair of
 153                      frame relay and ATM PVCs exist.
