What Does POTS Stand for in Telecom?

POTS, which stands for Plain Old Telephone Service, is a term used to describe the traditional analog telephone service. This type of phone service is exactly what it sounds like—a simple telephone connection with a basic set of features commonly found in homes and businesses.

Features of Plain Old Telephone Service (POTS)

POTS is the oldest and most basic type of telephone service. It includes the following features:

  • Dial tone: Dial tone is the sound heard when a landline phone is picked up. This sound indicates that the phone is ready to be used.
  • Voice mail: Voice mail allows users to leave voice messages that are stored in the network until the receiver picks them up.
  • Call waiting: This feature allows the user to receive multiple calls on one line. When the phone is already in use, an incoming call will be put on hold until the current call ends.
  • Caller ID: Caller ID is a feature that allows users to see the name and phone number of the caller before picking up the call.
  • Analog lines: An analog line is a type of copper wire connection that supports plain old telephone services.

Advantages of Plain Old Telephone Service (POTS)

Despite its age and simplicity, there are still many advantages to using POTS.

  • Reliable: POTS is extremely reliable and has been around for decades, which means it is much less likely to experience service interruptions than newer, more advanced telephone services.
  • Compatibility: POTS technology is widely compatible with a variety of telephone systems. This makes it easy to integrate with existing systems and move to newer ones.
  • Cheap: POTS is usually the cheapest of the telephone services available, with monthly fees much lower than other services such as VoIP.
