What does the acronym 'POTS' stand for?

The acronym 'POTS' stands for "Plain Old Telephone Service." This term refers to the traditional analog telephone service that has been in use for many decades. POTS is characterized by its use of twisted copper wire to transmit voice communications, and it provides basic telephone functionality without advanced features found in newer technologies.

Understanding POTS is crucial for those in the cabling and telecommunications field, as it represents the foundational technology upon which more modern telecommunication systems have been built. Knowledge of POTS is important for recognizing the evolution of telephone services and familiarizing oneself with legacy systems that may still be in operation alongside more advanced digital services.
