Is a fax implicitly an analog transmission? Or is there a digital data stream somewhere beneath the layer sending the photo that could be used like a modem?

If you've ever used a fax machine, you'll notice the classic dial-up handshake noises. Faxes are modems and vice-versa: any PC with a modem could send and receive faxes. It was a commonly advertised feature back in the day.
