POTS: Plain Old Telephone Service
Plain Old Telephone Service (POTS) is the standard, analog telephone service which remains the basic form of residential and small business telephone service nearly everywhere in the world. Plain Old Telephone Service was originally known as the Post Office Telephone Service in many countries. It has been available almost since the introduction of the telephone system in the late 19th century, mostly unchanged to the normal user since then despite the introduction of electronic telephone exchanges into the public switched telephone network since the middle of the 20th century.
