Answer 1

Answer:

A telephone line or telephone circuit is a single-user circuit on a telephone communication system. This is the physical wire or other signaling medium connecting the user's telephone apparatus.

A landline telephone (also known as land line, land-line, main line, home phone, landline, fixed-line, and wireline) is a phone that uses a metal wire or optical fiber telephone line for transmission as distinguished from a mobile cellular line, which uses radio waves for transmission.

Today, copper telephone lines that support POTS (Plain Old Telephone Service) are an aging infrastructure that's getting more and more expensive to maintain. Major telephone providers like AT&T have already started phasing out their support of analog POTS lines – promising for a full phase-out by 2020.
