In such a configuration,as the following graphic shows, the WAN interface and backbonecan be either Frame Relay or ATM. DSL VCs configured <strong>for</strong>VC-VC payload using the Cross-Connect netmodel generallyuse the Q922-1490 encapsulation type. This setting, used onlyon DSL VCs, specifies:• The DSL physical port encapsulation is Q.922, thusallowing Frame-Relay or FUNI VCs on it.• The encapsulation on every VC using that port is RFC-1490.Branch Office(IDSL Subscriber)Wiring ClosetWANCorporate HeadquartersClient:IPA: 192.168.10.2Gateway: 192.168.10.1Corporate LANRemote-Site LANSDSLModemBRI: 192.168.1.1Ethernet: 192.168.10.1PII: 1.4.2.22(Up to 6 PVCsPer DSL Port)PII: 1.2.1.900Set cmiface [1.4.2]netmodel=frameencapsulationtype=Q922PVC 900PublicNetwork(ATM or FR)UpstreamRouter192.168.1.2Set cmsubiface [1.4.2.22]destpii=1.4.1.900Set cmidslm [1.4.2]datarate=128VC-VC Payload Fowarding Model&KDSWHU$GYDQFHG&RQILJXUDWLRQ
