AddSecure Publishes PSTN Switch-Off Readiness Guide
AddSecure has released a guide to help businesses prepare for the Public Switched Telephone Network (PSTN) switch-off in January 2027. The guidance is particularly aimed at installers.

AddSecure, a provider of digital security and alarm systems, has published a detailed guide to assist businesses in preparing for the transition away from the Public Switched Telephone Network (PSTN). The initiative aims to help companies, especially installers, migrate to new IP-based solutions before the deadline of January 2027.
Industry experts emphasize that the decommissioning of analog lines necessitates proactive measures to modernize existing systems. AddSecure recommends replacing PSTN and ISDN-reliant systems with at least DP3-level dual-path connectivity, which typically combines cellular and IP communication routes to ensure signal resilience.
The company suggests a phased approach, starting with auditing the customer base to identify all clients using outdated lines. Proactive customer engagement is crucial, involving clear communication about the risks and offering suitable upgrade solutions. Businesses are also advised to plan installation timelines, working backward from the January 2027 deadline.
AddSecure offers its own dual-path alarm signalling solutions designed to meet British Standards and ensure reliable communication with Alarm Receiving Centres (ARCs). The company encourages viewing this transition as an opportunity to enhance customer services with faster signal transmission and real-time monitoring, rather than solely a compliance exercise.
