correct me if im wrong. But im trying to make a diagram of the physical layout of a LAN to a WAN..

I believe if you have a T1/T3 or higher it looks like this..

Node
Router
Modem----CSU/DSU ---T1/T3 WAN
ISP


Cable network looks like...

Node
Router
Modem
Cable WAN
ISP

Let me know if this is correct..

    The CSU/DSU is all that is required when using a T1/T3
    I don't claim to be an expert, but I sure would like to become one someday.
