The PSTN & ISDN switch-off
As the January 2027 deadline for the PSTN and ISDN switch-off approaches, businesses in the security and alarm signalling space must prepare for a total shift toward digital connectivity.
What is the PSTN switch-off?
The PSTN (Public Switched Telephone Network) and ISDN (Integrated Services Digital Network) switch off is probably one of the biggest shake ups to UK communications in decades. BT Openreach is phasing out the old copper-based telephone network by January 2027. This means that every home and business in the UK will need to move from traditional landline services and switch to digital. This will affect many things, including broadband, alarms, telecare devices, CCTV, and payment terminals. As traditional phone lines phase out, businesses need to prepare for the shift to newer, more efficient digital solutions and early preparation is essential to avoid any service disruptions. The transition doesn’t need to be stressful though with the right provider by your side.

The impact of the PSTN and ISDN switch-off
Legacy networks including the PSTN and ISDN have long been critical for transmitting alarm signals, controlling access systems, and monitoring vital infrastructure. As these networks are phased out in favour of digital alternatives, the security sector must prepare to ensure uninterrupted service.

Why it's essential to upgrade your PSTN systems
Many vital security systems have yet to move away from PSTN-based signalling. This delay places services such as fire and lift alarms in a precarious position where they may simply stop functioning. To mitigate this, it’s essential that homes and businesses move to digital paths to ensure continuous monitoring. Without these upgrades, customers risk ‘silent failures,’ where a system appears active, but is incapable of alerting emergency services.

Legal and financial penalties
Missing the PSTN deadline risks both legal penalties and invalidated insurance. As dual-path systems lose their backup connection, they may no longer meet the certification standards that are required for coverage. To remain protected and compliant, companies must migrate to digital signalling before their existing hardware becomes a liability.
