Here in Belgium we have something similar.
It's called
raw copper.
ADSL without a fixed telephone line?
There IS 48volt on the wire (at least here in Belgium), but there is no dialtone when you connect a telephone to it.
The thing is, the raw copper pair is more expensive (11.8 euro's) than requesting a cheap phone line (to be called on, not to place calls from) from the national telco (Belgacom). They only charge 7 euro's for that.
