Openreach has issued a strong call to businesses in the UK, urging them to transition swiftly to digital networks as the deadline for the Public Switched Telephone Network (PSTN) switch-off approaches. Slated for January 2027, this shift is critical as legacy systems near decommissioning. Companies still using outdated PSTN infrastructure may face threats to their operations and revenue streams.
Outdated systems, like payment terminals, security alarms, ISDN systems, and landline phones, may soon stop working. This could lead to substantial disruptions. James Lilley, Director of All IP at Openreach, emphasizes, “The nationwide transition to an All-IP network is a huge undertaking, and ensuring vulnerable users are protected has been a priority. Now that we are confident we have addressed those needs, it’s time for businesses to act.”
Businesses are encouraged to follow three essential steps: Review, Test, and Switch. Starting with a review of their current systems can help identify equipment still using PSTN. Free testing is available at Openreach’s labs to ensure compatibility with All IP networks. Transitioning to a digital solution as soon as possible is crucial. Resources and support are available through Openreach to assist businesses during this transition period.
The looming deadline indicates the urgency of the situation. Some Communication Service Providers (CSPs) are planning earlier switch-off dates, such as December 2025. Delaying the transition could result in increased costs, security vulnerabilities, and missed opportunities for growth. Openreach is adamant that businesses must act now to harness the advantages of advanced communication technologies that are vital for future success.
Through efforts like these, Openreach is modifying 18 million premises with new Full Fibre broadband infrastructure, aiming to cover 25 million homes and businesses by the end of 2026, with aspirations to reach 30 million by the decade’s end. This initiative is part of their broader commitment to significantly reducing emissions and modernizing their operations by switching to zero-emission vehicles by 2031.
