ISDN & PSTN
Switch-off

Ready your business and realise the endless opportunities by going all-IP

If your business communications are still operating on a PSTN/ISDN network, then now is the time to upgrade to an all-IP solution. 

The Public Switch Telephone Network (PSTN) will close by December 2025. By then, every phone line in the UK will have moved to a fully digital network that uses Internet Protocol (IP) across a fibre-based service.

This won’t just affect voice services, it may also mean you need to upgrade your broadband. Any equipment that currently uses the PSTN will stop working: alarms, EPOS machines, door entry systems, CCTV, faxes, and so on.

By moving to an IP-based solution now, you will future proof your business and avoid any disruption to business-critical communications.

What is ISDN?

ISDN stands for Integrated service digital network. It's a digital line that runs over a traditional copper wire. The problem with ISDN and PSTNTN is that with  businesses and homes using growing amounts of data, the current infrastructure and bandwidth just isn't sufficient for the modern world. 

Why is it being
switched off?

The UK's current phone network is old and difficult to maintain. As an essentially 20th century technology, the PSTN is increasingly out of kilter with the demands of 21st century communications.

Traditional phone usage is changing everywhere as people switch to mobile and internet communications. We all expect much more from modern phone services than the traditional technologies can deliver.

What do I need to do?

Take the opportunity to consult a reliable communications  expert such as Garnell. We will work with your business to find the best solution for your requirements and fully project-manage the upgrade and solution thereafter
