PSTN – Is Your Business Ready for the Big Switch-Off?

What is PSTN?

PSTN stands for Public Switched Telephone Network, the infrastructure behind the traditional telephone lines used in the UK. It is also used for fax machines, card processing machines and other technology. PSTN became the most reliable method of making voice calls and the main carrier for internet activity across the world.

What is the PSTN switch-off?

Openreach has announced that in 2025 the PSTN networks will be switched off following a gradual phase out. That means fixed line services such as analogue or ISDN lines will no longer be available and Openreach will cease taking ISDN orders.

2025 seems a long way off, but the national Stop Sell of phone lines as we know them, is 2023. From this point, businesses won’t be able to buy an existing type of phone line or copper-based broadband connection for new or renewed contracts. It is now important that businesses move to an alternative service to future-proof themselves.

Why is Openreach turning off the PSTN?

The PSTN utilises legacy infrastructure that is aging and becoming more difficult to maintain. In short, these legacy systems are now deemed out of date.

What will the replacement products be?

Voice over Internet Protocol (VoIP) solutions will replace traditional phone systems. For alternate data services, full fibre solutions and single order variants such as SOGEA and SOTAP will replace FTTC and ADSL connections.
