The UK telecommunications landscape is set to transform with the PSTN switch-off. But what exactly does this switch-off entail for businesses and individuals alike? This blog addresses some of the most commonly asked questions around the PSTN switch-off, and what this could mean for you.
What is the PSTN/ISDN switch-off?
You may have heard about the UK’s phone network going digital, but what does that mean for you?
By 2027, the Public Switched Telephone Network (PSTN) also known as the analogue copper cable telephone network, will be switched off and replaced by a digital full-fibre network. The Integrated Services Digital Network (ISDN) will also stop working.
The PSTN switch-off affects everyone (including businesses and individuals) currently using traditional telephone landlines and anything that currently uses the old analogue phone network such as alarms, door entry systems, fax machines, and more. And customers will need to ensure their communications systems move to a digital, cloud-based phone system.
Why is the switch-off happening?
Did you know the PSTN, analogue copper cable telephone network has been in use since 1876? And ISDN though more modern, has been around since 1985.
While this legacy is impressive, it also underscores the pressing need for system upgrades. The shift towards digital systems is evident across all sectors, driven by increasing demands for modern phone services that traditional systems struggle to meet.
What is the PTSN switch-off deadline?
You may have seen reports about the switch-off being in 2025, which could conflict with others saying 2027.
To cut a long story short, the 2025 deadline has been extended to 2027, to ensure those who live in areas with poor internet connections and vulnerable people can safely make the switch ahead of time. You can find out more about the deadline change here.
How can I ensure I’m prepared?
Step 1: Find out what systems need upgrading
If you currently have a landline that uses the PSTN analogue system you will need to ensure you switch over to a VoIP-based (Voice over Internet Protocol) phone plan. Your ability to do this depends on your device, some may require an adapter where you plug your existing phone into your router or a new socket, whilst others may not be suitable and may need to be replaced. If you don’t want a VoIP phone plan, you can be transferred to a broadband-only plan.
Also consider whether there are other systems which are reliant on the analogue line, such as fax machines and alarms. If you’re unsure what systems may need switching, we advise you to get in touch with your provider.
Step 2: Ensure your internet is fit for purpose
As more devices move onto a digital network, an increased strain is likely to be placed on your broadband bandwidth, which could affect the clarity and effectiveness of calls. Make sure to consider whether you have enough internet capacity to handle the switch. If you’re unsure whether your service meets the requirements we advise you to get in touch with your provider.
