It also depends on the kinda card you are using over there in your router for this connectivity.

If you are using normal WIC card you can refer the below link for configuring up the same.

if you are not aware of the card type then do give show version command and paste the output here.

If I am understanding your post correctly then the topology is: DSL network to DSL modem which is connected to proxy server, and proxy server connected to 2611 router. It seems to me that the likely problem is something in the setup of the proxy server. Is the proxy server set up to pass traffic from the DSL modem interface to the router interface?


If the proxy server is setup correctly to pass this traffic then I would look next at the possibility that the proxy server is not logging in on the DSL modem to establish that link as active. Does the DSL modem have an ID and a password that it expects from the device that is connecting to it? And is that ID and password correctly set up on the proxy server? From the proxy server are you able to ping the DSL modem?
