I want to know the answer to the following question:
What does POTS stand for?
All the background I'm provided with is that "The use of audio modems in the transmission line allow for the use of POTS, or the Plain Old Telephone System, in some low-speed applications, such as videotelephony, because they convert the digital pulses to/from analog waves in the audio spectrum range.". Is that enough to answer the question?
