It describes Cross-Connects from a DSL VC to a WAN VC.Since DSL VCs defined in the cmsubIface table have no Fwd-Mode object, operators must look to the Cross-Connected WANVC <strong>for</strong> the FwdMode, which the CE<strong>150</strong> uses <strong>for</strong> both the DSLVC and the WAN VC. In these cases, the DSL port has a Fwd-Mode=Per-VC, since each DSL VC has its own FwdMode.DSL Port VC EncapsulationsNetmodelDSL VCEncapsulations aWAN VCEncapsulationsFwdModeNotesCross-Connect None None VC-VC-payload payload transparent,including PPP-RFC2364.This is notreally a translation.FRF.5 FRF.5 FRF.5Cross-Connect RFC1490 RFC1483 FRF.8-1490-1483 FRF.8 translateNone VC-VC-payload payload transparent,including PPP-RFC2364FRF.5 FRF.5 FRF.5Cross-Connect RFC1973 RFC 1973 PPP-Transparent Like VC-VC-payload, butwith encapsulationsspecified and validatedRFC 2364-null PPP-Translation FRF.8 translateRFC 2364-LLC PPP-Translation FRF.8 translateNone VC-VC-payload payload transparenta. 1 For DSL VCs configured with a cmSubIfaceTable entry, the VC encapsulation is implied by the DSL port encapsulation.For DSL VCs configured with a cmIfaceTable entry, the VC encapsulation is specified directly by that cmIfaceTable entry.$SSHQGL[$2YHUYLHZRI'DWD(QFDSVXODWLRQ
