Landline phones used to be the kings of communication in the past. As with all kings, to conquer the world, a new king comes and replaces the old king.

But fortunately, landline phones are not completely replaced as of now. It still has its place in the communication world, in places where VoIP doesn’t reach.

Plain Old Telephone Service, also known as Public Switched Telephone Network ☎️, uses landlines for handling phone calls that require copper wire connection. 

In this article, we will learn more in detail about how POTS has become a thing of the past and why you should consider a better solution like VoIP.

What is Plain Old Telephone Service (POTS)?

Plain Old Telephone Service (POTS) is a kind of phone service that uses analog telecommunication technology. POTS is also referred to as PSTN (Public Switched Telephone Network). Public telecommunication requires Infrastructure and services that are provided through the PSTN.

The PSTN is a collection of a circuit-switched network of telephones managed by national, regional, and local telephony companies around the world.

The full form of POTS is Plain Old Telephone Service and it was first introduced in 1876 at the World’s Fair. It was the beginning of a new area for communication systems.

Communication takes place between two parties via a pair of twisted copper wires. These copper cables are the transmission medium used for sending analog voice signals. 

The caller’s sound waves or voice messages are changed into electrical signals and passed through the network to the receiver.

Telephone lines, cellular networks, microwave transmission links, communications satellites, fiber optic cables,  and under-the-sea telephone cables are all interlinked via switching centers allowing many phones to communicate with one another.

PSTN, Plain old phone services, fixed-line phones, or simply landlines are all terms used for phones. PSTN phones are still widely utilized and regarded as a common mode of communication.

The PSTN, which began as a network of fixed-line analog telephone systems, is now almost totally digital in its network infrastructure which incorporates mobile and other networks in addition to fixed lines.

How does Plain Old Telephone Service System Work? 

The many aspects of the POTS network collaborate to carry out a series of processes in order to make a phone call.

However, the traditional telephone service creates a dedicated circuit between two points for the period of transmission.

Businesses are linked to central offices in the area through a simple telephone service. Long-distance offices or residents are connected to the central office.

The call is routed through one or more switching offices that operate locally, nationally, or worldwide to make connections and allow the parties to interact over the POTS line.

The old traditional telephone call, conducted over PSTN, used circuit-switching as a technique of communication. 

This is what typical traditional Old Plain Telephone Services work like. 

  • The PSTN networks are linked by central offices that serve as phone exchanges, each serving a specific geographic area.

  • When person A calls person B, the telephone network tries various circuits to discover an access channel. Before they can begin talking, they must first establish a link.

  • Once a channel has been selected, it ensures full bandwidth and stays connected for the rest of the communication session unless users disconnect.

  • You are basically renting the lines when you make a PSTN call. This is why making an international or long-distance phone call was so costly.

However, just like digital data packets, you can now obtain phone service distributed over the internet using VoIP technology.

The largest circuit-switched network is the plain old telephone system (POTS).

Pros of using POTS Line are:

  • Works even when power is cut off or Internet connection.
  • It is a more secure and dependable channel of communication.
  • Easy-to-use infrastructure 
  • Cost Less than VoIP

Cons of using POTS Line are:

  • Even if the two devices are not sharing data, the connection path will stay active which will be wasting memory.
  • It takes longer than packet-switching to make a connection between two hosts before data can be exchanged.
  • Limited Features
  • Maintenance is High

The landline phones are inflexible because they are fixed on your work desk with a copper wire connection.

5. Fewer features and services

As much as Plain Old Telephone Service (POTS Telephone Line) intends to provide the best features and services, they are still no match to the services of VoIP phone systems. On top of that, getting them is costly as well as time-consuming.  There may be a need to get additional hardware to add a feature.

POTS VS VoIP: Which is right for you?

Plain Old Telephone Service (POTS) phone line may appear to be the more expensive alternative compared to VoIP. However, It is more reliable in locations where cellular or internet service is poor or non-existent. A POTS landline phone system will come to your rescue if everything else fails.
