:$13RUW(QFDSVXODWLRQVCurrently, WAN ports do not have cmIface entries or explicitconfiguration. Since the hardware for each WAN port supportsonly one encapsulation, the encapsulation is implied by thehardware.Frame-based WAN interfaces (such as DS3-Frame and Quad-T1) imply a WAN port encapsulation of Q.922 (Frame Relay).ATM WAN interfaces (such as DS3-ATM) imply a WAN port encapsulationof ATM. In the future, frame-based WANs may supportnon-Q.922 encapsulations and you will then have toexplicitly configure the WAN port encapsulations.:$19&(QFDSVXODWLRQVWAN VCs (Frame Relay and ATM) support the following encapsulations.For 1483 or 1490 encapsulation, the netmodel determineswhether the frame-type is IP PDU or MAC PDU.WAN VC EncapsulationsWAN VCEncapsulationValid Netmodels Frame-based VC Format ATM VC FormatNone None, Cross-Connect Q.922 address + payload AAL5 payloadRFC1483 VWAN, IP, CVPN, HDIA, Q.922 address + 1483 AAL5 + 1483Cross-Connect(MAC or IP)RFC1490 VWAN, IP, CVPN, HDIA Q.922 address + 1490 AAL5 + 1490(MAC or IP)RFC1973 Cross-Connect Q.922 address + RFC1973RFC2364-null Cross-Connect none PPP payload + AAL5 trailerRFC2364-LLC Cross-Connect none LLC header + PPP payload +AAL5 trailerFRF.5 Cross-Connect AAL5 + FRF.5(WKHUQHW3RUW(QFDSVXODWLRQVSince industry standards unambiguously define a single encapsulationfor each protocol, the CE150 only accepts Encapsulation=None.7UDQVODWLRQVFor the Cross-Connect netmodel, the CE150 does not terminateprotocols, but may convert headers. For non-VC DSL port encapsulations,there is only one logical interface per DSL port.For DSL port encapsulations of Q.922, RFC1973, or ATM, eachDSL VC may be a separate logical interface.&RSSHU(GJH,QVWDOODWLRQDQG2SHUDWLQJ*XLGH
