Bonjour, having been without Internet for a few days and without anything, I wanted to know if there is a way to test a phone line with a multimeter or something else?

Hello
If the line is NOT unbundled, a "normal" telephone will work and with a multimeter there will be a voltage of around 48 volts
If the line is unbundled then there is nothing on the wires .............

Hi,
you mean totally unbundled, in partial, we still have telephony on it.
But indeed, it concerns fewer and fewer people.
On the other hand,
depending on the DSLAM model,
some send 48V to "wet" the lines and facilitate remote testing.
Other naked ADSL lines (so totally unbundled too) leave the 48V on the line for testing as well.
There is so much excess 48V in the cabinets that it doesn't cost much to add it back to the lines even if it's unnecessary.
In short,
the rules are sometimes a little more blurred than the general rule you explained.

Yes, I know that in total unbundling, it's never clear for the tone; the only clear thing is that there is no more tone in total unbundling, it works "like before" in partial unbundling.
