What Is POTS (Plain Old Telephone Service)?

POTS (Plain Old Telephone Service), a service many of us know well, is a telephone system that provides analog voice transmission over twisted-pair copper wires. POTS also provides operator services and features such as call progress tones (for example, ringing signals), subscriber lookup, directory assistance, and long-distance calling. It was the telephone service that carried our voices to the other end of the line over copper wires, and it was installed in almost all of our homes, so most of us have used it. It was created to enable voice communication over copper cables spanning countries and continents, and its main purpose was to make communication easier.

However, as technology has developed, our communication needs have changed, and systems offering more possibilities have emerged. VoIP, for example, is a telephone system that offers many more communication services. That’s why POTS is no longer as common as it used to be. It is still used and still available in some homes, but businesses, especially those with many employees, generally do not choose POTS because it does not adequately meet their needs.

History of POTS (Plain Old Telephone Service)

To briefly summarize the history of POTS, the first telephone lines stretched across entire countries and hung on poles, but as technology advanced, most of the lines were moved underground. The service was originally known as Post Office Telephone Service, because in the early days, callers relied on post office operators to connect them to whoever they wanted to reach. Later, the service was taken over from the post offices and became known as Plain Old Telephone Service. Over time, the widespread availability of POTS also allowed new communication devices such as modems and fax machines to use it.

How Does It Work?

The basic POTS setup has remained almost the same for years. Because it was built on copper wiring, it was extremely difficult to develop further. Many upgrades have been made to bring the components of this phone system into the digital age, make it compatible with newer technology, and improve it, but the copper wiring has made this difficult. With Plain Old Telephone Service, the sound waves of the caller’s voice are converted by the telephone handset into electrical signals that travel over the network. For both parties to communicate smoothly, a dedicated circuit must be established between them.

As mentioned above, in POTS, audio signals are converted into electrical signals to be transmitted over copper cable, and hybrid converters are used for this conversion. However, for long-distance calls, the copper cables are connected to fiber optic cables, so the audio signals are transmitted as optical data. Fiber media converters are used to convert the electrical signals into optical signals.

What Are Its Important Components?

The POTS system is built on several important components. These components are:

• Speakers
• Hybrid Converters
• Microphones
• Ringer Unit
• Dial Keys
• Casing
• Hook Switches

Advantages and Disadvantages of Plain Old Telephone Service

Like every service, POTS has both advantages and disadvantages. It has shortcomings, but it also offers benefits that may be enough for your needs. Let’s examine these advantages and disadvantages together.

What Are the Advantages?

The POTS system offers several benefits, and these may match your needs. By examining these advantages, you can decide whether it is the right system for you.

POTS does not rely on the internet, so you can keep communicating even if your internet connection goes down during the day. POTS lines also provide fairly consistent connectivity, so your business does not experience irregular outages at any time of day, and you can continue to receive uninterrupted service. In addition, it is very useful for emergency calls: thanks to this fixed connection, emergency services can locate you instantly when you call them. Apart from this, it does not require any extra equipment to operate, and your employees can use it easily without any training.

What Are the Disadvantages?

Of course, as technology develops, our needs and demands change with it, and we lose interest in systems that do not improve. Since Plain Old Telephone Service is an old telephone system, it has many disadvantages today. Let’s look at what these disadvantages are.

The main disadvantage of POTS is cost. Beyond the installation itself, repairing the system when it breaks down can be very expensive. Long-distance calls are another cost: if your plan does not include long-distance calling, these calls can be very costly. In addition, a POTS phone is a fixed line that you cannot take with you, so if you decide to work remotely, using POTS will be inefficient. Moreover, modern phones offer features beyond calling, such as messaging and video chat, and POTS does not have these features.

Conclusion

As we mentioned above, POTS is an old technology that allows us to communicate over copper wires. Unfortunately, this system has not been developed further and has not kept up with technology. Therefore, it is no longer a preferred way to communicate. Instead, people prefer systems that offer multiple functions, better meet their needs, and keep up with technology. However, some companies still use and prefer POTS because it already meets their needs and they do not require additional functions. In this article, we covered the key things you should know about POTS so that you can choose the system that fits your needs.
