Hello guys, not much of a difficult question but need a consice answer.

To my understanding if i want to connect a DSL line to my Cisco Router, i need to by a CISCO DSL WIC.

However, someone is telling me that you can connect the DSL line (ethernet) to the Router's ethernet port. Is this correct? If that's the case then why have CISCO DSL WICs?

All along i though i need to connect the DSL line to the CISCO DSL WIC then connect a switch to the ethernet port and then connect other routers through the serial ports for lab purposes for example.

Please confirm

Thanks

It depends upon the layer 2 hand-off that your ISP is providing.

If via ATM, you will need an ATM card.  If via ethernet, a dual port ethernet router will work.

Are we saying that if my ISP has an ATM, i need to connect my DSL modem ethernet port to an ATM card on the CISCO router to work?

DSL is typically handed off to the customer via ATM or Ethernet.  Find out what kind of connection your ISP will be providing to you.

If it's ATM, you will need an ATM card in your router.  The ATM card will connect to the ISP network.  The ethernet interface will connect to your local area network.   You will not connect any ethernet interface to an ATM ISP connection.

Should the ISP be handing you an Ethernet connection, you will need a dual port Ethernet router:  one ethernet port to connect to the ISP network and one Ethernet port to connect to the local area network.

An internet cable connection will require a cable modem at your end to talk to the cable network.  The output of the cable modem is ethernet (to the router).  The ISP should provide this device.

I believe that the DSL WIC for the Cisco router is an ATM card.  ATM can be setup either routed or bridged.  If you do not use the equipment to terminate the DSL line from your ISP, you will need to find out that additional information so that you can properly configure your router.
