the link above configures the router to access internet.
I wonder if this router is connected to T1 line or to a ADSL router.(it seems like it's a connection to T1 line)
I have seen configurations where they use Dialer interface, I believe that 's when they connect the router to a ADSL in order to provide internet for users in the LAN.
My Goal is to ask an expert out there to paste the configurations used in both case.
Case1--Connecting LAN --->Cisco Router--->ADSL
Case2--Connecting LAN---->Cisco Router--->T1
