Suse 9.2 mini install ISO - How to use FTP install with DSL

I downloaded the Suse 9.2 mini install ISO. I have a DSL connection. In order for me to do an FTP install, I need to establish ( log in ) to my DSL provider, so that I can then select the FTP option to do the install. Is this possible? Can I manually make my DSL connection after booting from the ISO CD ?
