The Big Switch Off

Significant changes that affect us all in some way are on the horizon for businesses as Openreach, a subsidiary of British Telecom, bids farewell to the Public Switched Telephone Network (PSTN) and introduces a ‘full-fibre’ network.

BT Group’s recent announcement about the delay of the 2025 PSTN switch-off to January 2027 is a significant development for businesses across the UK. Initially set for 2025, this extension provides an essential buffer for consumers and companies to seamlessly transition from analogue to digital landlines.

Why the Delay?

The revised timeline comes after BT Group introduced several enhancements to protect vulnerable customers and those with additional needs, such as telecare users. Ensuring these individuals are not left behind in the digital transition is a priority. This delay allows more time to implement safeguards and ensure that all necessary support structures are in place.

PSTN Switch Off: What This Means for Your Business

The upcoming PSTN Switch Off offers businesses a prime opportunity to transition smoothly to digital landlines. Here’s how to prepare:

  1. Review Your Technology Footprint: Identify all equipment still connected to the PSTN. Plan for upgrades to digital alternatives, including alarms, payment terminals, lifts, fax machines, and emergency lines.
  2. Engage Early with a New Provider: Start testing existing equipment for compatibility with digital lines. Tech IP offers free quoting services to help you prepare for a seamless transition. Early engagement ensures everything is ready ahead of the PSTN Switch Off.

The PSTN switch-off, driven by Openreach, is the shutdown of the Public Switched Telephone Network by January 2027.

The PSTN switch-off signifies the retirement of the traditional telephone network that has been in use for over a century. Openreach is moving towards a more advanced ‘full-fibre’ network, a change that impacts how businesses handle their communication infrastructure.

This shift is driven by the need for more efficient and modern communication technologies. The traditional PSTN, designed for analogue telephone calls, is coming to end-of-life.

The PSTN switch-off has implications for businesses relying on traditional phone lines. It means the end of Wholesale Line Rental (WLR) products, including ISDN and analogue lines. If your business is still using these services, it’s essential to adapt to the changes to ensure seamless communication.

What Does The Big Switch Off Means For Your Business?

Put simply, telephone lines with a telephone number that aren’t already VoIP and running over the internet, will no longer be supported by the UK networks from January 2027 onwards. This means if you use any of these lines you will need to switch.

Need some straight-talking facts about these upcoming changes and how they affect your business? You should take into consideration what will need to change by 2025 at the latest, and there is no harm at all in understanding the changes coming.
