As soon as either side goes "off hook" it automatically "rings" to the other
side. Imagine a big pipe that runs directly from you to them. You don't
have to "tell" the other end of the pipe where to go, its already there.
You just take the cap off one end, yell down the pipe, and the other side
hears you and takes its cap off and you can then look at each other and talk
to each other through this pipe. You're "connected".

True but its convenient to think of it as a "modem".

Yes but the "modem" in this case is a terminal adapter.
If you get Courier I-Modems you can put them in Leased Line Mode. From the
computer's point of view the Courier is just another modem and you have a
perfectly ordinary serial port that you can write and read data from. Just
like any other modem or serial device.
