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.
Did you know that the PSTN and ISDN will be switched off by January 2027?
The Public Switched Telephone Network (PSTN) and Integrated Services Digital Network (ISDN) are being switched off, marking a major transition in telecommunication technology. As traditional phone lines phase out, businesses need to prepare for the shift to newer, more efficient digital solutions. This change impacts all industries, and early preparation is essential to avoid service disruptions.

Guide: The PSTN and ISDN switch-off
Trust in both the team and the service was vital as we transitioned away from legacy networks, and it gave us the confidence that we could continue servicing our customers to the best standards.

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.
How to navigate the PSTN switch-off
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.
