For an X.25 PVC between a Passport 4400 unit and a FRAD, an entry in the PVC definition table could be as follows:
LCN 1 on physical port 159 (packet layer IfIndex 161) is bound to LCN 1 on virtual port packet layer IfIndex 51. The devices attached to the physical port of the Passport unit and to the FRAD should expect the designated LCNs to be used as PVCs. The following are two illustrations showing the setup of the PVC.
