Yes, it is.
No it isn't. The line into my house (and everyone else's house) is
copper, delivering an analogue voltage to an analogue handset.

Not here it isn't. The main voice line coming into the building is ISDN.

The fax line is analogue though (and is the one that carries the ADSL
broadband as well).
