In my country, to connect to the internet one must have both an

The same applies here in Switzerland. Sometimes the infrastructure
provider and the ISP are one and the same. (Swisscom and Bluewin for
instance).

To connect, one uses an L2TP 'dialer' to 'dial into' the
infrastructure provider. Of course, there is no Linux dialer so
Linux users are either using an old, unmaintained script from a
defunct ISP or using a router (most consumer grade routers can dial
L2TP connections).

A couple of years ago I did some experiments with an ADSL plugin card
- I'm pretty certain I used plain PPP/expect scripts for logging in
and all that.


Yes, the outdated scripts used PPP but when connecting via a router
one uses L2TP. The ISP supports both.

That must be infrastructure specific and not really a CPE hardware
issue. Our ADSL connection also uses a router, but the tunneling is
with PPPoE or PPPoA. L2TP and PPPoX must be fairly closely related, I
would think.
