What is POTS? Origins of the Plain Old Telephone Service


POTS or Plain Old Telephone Service is a term that refers to the traditional landline phone system that many of us are familiar with.


Put simply, POTS is an analog voice transmission system that relies on copper twisted pair wires to connect callers. This system originates with the invention of the telephone by Alexander Graham Bell back in 1876, though there have been some upgrades since then.


Originally, the copper telephone lines were suspended overhead on poles or across rooftops. As technology advanced, though, it became more common to bury these lines underground. These traditional copper telephone lines are what we refer to as copper landlines or POTS lines.
