You are right about that. In order to fax a document, for example, you have to use the telephone cable from the jack on the wall to the back of the fax machine or a do all printer that also has a FAX feature inside. A DSL modem also uses the telephone line, sometimes as explained here.

But I don't know about cable modems. In this case I imagine that no telephone line is used, but a cable. Also, if the internet service is provided through the telephone line, the modem has to be connected to the telephone jack on the wall.

If you use nDSL you're bound to have at least one phone jack somewhere in your house/flat/shack/whatever, unless you're clever enough to figure out how to hard-wire the transceiver directly to the line (echoes of Ma Bell!).

Just saying.

We have a house phone, but it doesn't plug into a jack. We have a device from Verizon that plugs into an electrical outlet, and the phone plugs into the device with standard phone wires. It's not cell service, and it's not the internet. It's kind of a mystery to me.
Probably broadband-over-power-lines/IEEE 1901; yuck-o, folks.

I covered up the exterior of the RJ11 analog holes in my home built in the 1980s each with a piece of tape, as I have plugged unused electrical outlets with child proof safety protector plastic plugs. Especially for exterior walls, one less source for small bugs to get in, plus keeping out of season cold or hot air out, with every little bit helping on HVAC electric bills.

Been landlineless and cell phone only since the last decade, as not need two phone bills plus spam calls which hits landllines more so than cell phones. Unless running the screen all the time, typically have two days of juice on recent smartphone, plus bought a Mogix battery charger with 10000 mah of juice from Amazon ($20-30) years ago which easily fits into a pants pocket. If I keep the Mogix charged, the cell phone tower backup generator would run out of juice before my phone ever would.

No reason to have them anymore. New construction they just use Cat5. You can just hook your phone up to that.

Cat-5/6 also makes excellent multiline telephone cable, especially for that old 4-line NSAT&T Dimension PBX in the hall closet.
