IGX Questions

[Ngo Van Dzung]

Hi All, In my company we using IGX 8410 to setup a private framerelay network. I have 2 IGX 8410 connect together using Network Trunk Module and over leased line. In each IGX we are using Universal Frame Relay Module (UFM) to connect to the routers. I know that if the Router is near by IGX we can connect drirect from router to V35 port in UFM - U Back Card by V35 Cable. But now I have one router which is far from IGX (about 2 km) so I want connect from router to V35 port in IGX over leased line. I don't know what equipment I will need for this connection, may be NTU? If any one have experiences in Wan Switch, please help me.   Cheeres!
