There's more to the PSTN switch-off than meets the eye

What is the PSTN switch-off? The impending PSTN (Public Switched Telephone Network) switch-off isn’t just about replacing traditional lines. It’s a seismic shift that impacts far more than most realise – and if you’re not prepared, it could cost your business dearly. Most companies are aware that traditional analogue lines and ISDN systems for calls and broadband are being phased out by January 2027. But what many don’t see is the vast ripple effect of this transition – touching everything from lifts to life-critical systems, cash machines, and even traffic lights. What does the PSTN switch-off mean in simple terms? When it comes to the PSTN switch-off, it’s easy to think that it is just about phone lines. But the truth is, it’s much more complex. Here is what’s at stake: Life-saving systems: fire alarms, major medical and safety devices, emergency alarms in care homes, emergency pendants, telemetry services monitoring boiler rooms, dams, sluice gates, and substations. Public infrastructure: traffic lights, bus stops, speed cameras, and traffic management systems. Business-critical devices: PDQ and payment terminals, ATMS, CCTV, video surveillance, door entry, security systems, and remote access points. Transport & emergency services: roadside AA/RAC recovery alerts and devices, and emergency phone lines in hazardous environments. Telecommunications & internet: leased lines, private networking facilities, dial-up lines, broadband DSL services, and international leased lines. Community & public services: emergency teams and vehicles, payphones, modems, industrial control, public alerts, and more. If every one of these vital systems suddenly loses connectivity – chaos, downtime, and danger could follow. The possible business impact of the PSTN switch-off could be financial losses, public safety risks and erosion of customer trust. The PSTN switch-off is a vital business resilience issue – the time to act is now Unlike many providers who may focus on the obvious, we see what others miss. Our team dives beneath the surface, examining your entire network ecosystem to identify what’s at risk when the PSTN switches off.

Check out our iceberg infographic to see a quick glance of the PSTN switch-off picture. The switch-off is just the tip of the iceberg.

What will happen to businesses when landlines go digital?

Preparing your business for the WLR switch-off and ensuring a smooth transition Most businesses currently rely on traditional analogue lines, ISDN, or broadband connected through Wholesale Line Rental (WLR) – the infrastructure powering your calls, data, security systems, and more.

The countdown is on - Openreach’s deadline to shut down traditional analogue phone lines, ISDN, broadband, and other vital WLR-connected services is January 2027 (or even sooner). If you’re not fully prepared, your business could face serious disruption: Your phones may stop ringing, cutting off essential customer contact Lifts and critical facilities could cease functioning Broadband and internet services might go offline unexpectedly Your customers’ access to your services could be lost What exactly are your WLR lines powering? Many businesses don’t realise just how much relies on their existing WLR lines and traditional networks.

Is your retail business ready for the PSTN switch-off?

PSTN switch-off for retail organisations A groundbreaking change in UK business communications is happening, and it’s heading straight for retail stores like yours! The PSTN (Public Switched Telephone Network) switch-off – the planned phase-out of traditional phone lines – is the most significant technological shift in the UK in three decades. Are you prepared to adapt? Here’s everything retail businesses need to know to stay connected, without disruption to daily operations, and futureproof their organisation. What is the PSTN switch-off and why should retailers care? Since 2023, BT and other UK telecom providers have been ceasing the sale of legacy communication services like conventional phone lines, ISDN, and analogue lines.

For retail stores and other enterprises, the biggest change in UK telecoms history impacts everything from your EPoS systems and card payment machines to emergency alarms, lifts, door entry systems, and beyond. Many of these critical systems still rely on legacy analogue or ISDN connections, which will be no longer supported. And here’s the thing: it’s easy to overlook how many devices depend on old PSTN lines. But disruption to these systems could seriously impact your day-to-day retail operations. Why is the PSTN switch-off a critical change for retail organisations? Traditional PSTN lines and ISDN connections are being phased out, replaced by fibre-based ‘all IP’ technology.
