Introduction
There’s been a lot of chatter about the impending switch-off of the Public Switched Telephone Network (PSTN) in the UK, slated for 2025. In this article, we’ll break down what this actually means in everyday terms and delve into how it will impact you, the reader.
What is the PSTN?
The PSTN is essentially the old analogue phone line network that’s been with us since Alexander Graham Bell first shouted “Mr. Watson, come here, I want to see you”. It’s the traditional infrastructure that has been used for voice communications and broadband services.
In simple terms: PSTN is the system that has historically made our landline telephones work.
What is the PSTN Switch-off?
In 2025, BT (British Telecom), which runs the UK’s telephone infrastructure, plans to retire the PSTN. The company is migrating to an entirely digital network, namely, the Internet Protocol (IP) network.
In simple terms: The old landline system is being switched off, and everything is moving online.
Why is this happening?
The PSTN is old, very old. It’s expensive to maintain, has limited capabilities and doesn’t align with the digital direction our world is heading. The transition to IP-based systems is in line with the global trend towards digitisation.
In simple terms: The old system is outdated, costly, and not up to speed with today’s tech needs.
What does this mean for the average person?
Telephone Services
With the switch-off, all voice calls will transition to a digital service known as Voice over Internet Protocol (VoIP). To put it simply, instead of your voice travelling over traditional phone lines, it will now be sent digitally over the internet.
In simple terms: Your calls will now be made over the internet, rather like a WhatsApp call or a Skype call.
Broadband Services
Currently, many broadband services, particularly in rural areas, are delivered over the PSTN. After the switch-off, all broadband services will have to be delivered over fibre (or alternatives like 5G), offering faster and more reliable connections.
In simple terms: Your internet might become faster and more reliable after this switch.
How will this impact you?
Cost Implications
With the transition to VoIP, you’ll need a strong, steady internet connection for your calls. While many of us already have this, for some, particularly in rural areas, this might mean having to upgrade their internet package, potentially at an additional cost.
In simple terms: You might need to pay a bit more for a better internet connection.
Equipment Updates
Some older telephone handsets might not work with VoIP services. If this is the case, you’ll need to purchase a new phone that’s compatible.
In simple terms: You might need a new phone.
Emergencies and Power Outages
Traditional phones are powered by the telephone line, so they work even during power cuts. With VoIP, if the power goes out, so does your home phone service unless you have a backup power solution.
In simple terms: Your landline won’t work during a power cut.
Conclusion
The PSTN switch-off is a big leap forward towards a digital future. While the transition will bring challenges, it also presents opportunities for more reliable, faster, and advanced services. The key is to stay informed and prepare for the changes ahead.
