Extended-label ATM interfaces are virtual interfaces that are created on first reference like tunnel interfaces. They are similar to ATM interfaces except that they only support TC-ATM encapsulation.

What kind of interface have you inserted into the router.

I have installed HWIC-1ADSL Card.

But its not detecting.

Im having following version.

Cisco IOS Software, 2800 Software (C2800NM-ADVIPSERVICESK9-M), Version 12.4(7a),


I want to know that above version will support for ATM Interface or not.


Im confused about IOS Version becoz im have IOS 12.4(7a), cisco suggest minimum IOS is 12.4(4)T.

Which is the latest one.

Kindly update me what to do next.
