PPPoverEthernet vs. PPPoverATM

[linux_abbestia@virgilio.it]

I'm about to turn to ADSL connection to Internet and I'm taking in consideration
all the choises the Provider offer. I was surprised in seening they offer
an ADSL service not only using the PPP-over-Eth protocol, but also with
the PPP-over-ATM. So my question is: if I choose the second system, is debian
support it? what is the best configuration (I think I will use the following
hardware: ADSL modem + Cisco 25xx router through Ethernet cable connection)?
Thanx in advance!

GNU/Debian Linux RULES anyhow!
