The ADSL interface ofM1112 functions completely automatically and all configurationrelated to the ADSL connection is done at the access multiplexer in theoperator’s premises. The network operator can set the data rates as apart of the network management functionality provided by NokiaDSLAM.2.2.7 Point-to-Point Tunneling Protocol (PPTP)When PPTP local tunneling is used, a local network client initialises aPPTP-tunneled PPP connection (VPN) to Nokia M1112. The modemterminates the tunnel and all data from that terminated local PPTPtunnel will be forwarded to an assigned ATM VCC by using PPP overAAL5 encapsulation. Thus, each local PPTP tunnel requires anequivalent ATM VCC assigned to it restricting the total number oflocal PPTP hosts to 8.Local tunneling is used when there is a need to have one or morecomputers connected independently to different networks. Forexample, in remote work application, the rest of the family may beusing the common ISP services and one or two family members need togain access to their corporate networks. With local tunneling, theseremote workers may be connected to a different network than the restof the users.Local tunneling is activated using the PPTP client running, forexample, in Windows The destination IP address must be M1112LAN/VBRIDGE IP address depending on the configuration. PPPpackets within PPTP are mapped to the configured VCC. M1112 hasthree different ways to choose the ATM VCC that will be used fortunneling: Automatic, chooses the first free VCC Chooses the VCC number using C:number, where number is from1 to 8. C:number is typed after the M1112 IP address in PC’s PPTPclient Connect To window (see Figure 2-5). Chooses the VCC number using N:name, where name is theVCCx description. N:name is fed after the M1112 IP address. |
