What’s The Difference Between PSTN and ISDN?

Have you ever wondered what makes your phone calls sound so clear, or why your internet connection can be super speedy? 

Well, it all comes down to the technology behind it. 

In this article, we’re going to dive into the world of PSTN vs ISDN and uncover the key differences between them. 

You see, PSTN and ISDN may sound like tech jargon, but understanding them can help you make better choices when it comes to communication. 

So, let’s break it down and discover the real deal behind the difference between PSTN and ISDN!

What is PSTN?

Public Switched Telephone Network (PSTN) is a communication system that has been used for over a century. PSTN is used to connect telephone calls between different locations.

In fact, the PSTN network has a vast network of copper wires and switching centers to connect people around the world.

When you make a call using a traditional landline phone, your voice is converted into analog signals. These signals then travel through the PSTN network to reach the other person’s phone. Public Switched Telephone Network systems use various technologies to ensure that the call is reliable, and your sound quality is clear.

However, with the advent of digital technologies, PSTN is becoming less popular. Furthermore, many countries are phasing it out in favor of more modern communication networks such as ISDN and VoIP. Nevertheless, Public Switched Telephone Network systems continue to play an essential role in connecting people worldwide. As such, many people still rely on it for their communication needs.

What is ISDN?

Integrated Services Digital Network (ISDN) is a digital communication network that was developed in the 1980s. It was designed as an upgrade to the traditional PSTN system.

The difference between PSTN and ISDN is that ISDN is able to provide users with faster data transmission and better call quality.

Moreover, ISDN uses digital signals to transmit data, which is more reliable. As such, it can handle multiple calls simultaneously. This makes it ideal for businesses that need to handle a large volume of calls.

Additionally, Integrated Services Digital Network also comes with a feature called “channel bonding”. This allows two or more ISDN lines to be combined to increase the data transmission rate. This acts as a significant advantage for businesses that need to transfer large amounts of data quickly.

For these reasons, Integrated Services Digital Network is considered a more modern and efficient communication network that offers several advantages over PSTN. It is mainly used in businesses and organizations that require a reliable and fast communication network.
