UPDATE: The PSTN and ISDN 2025 Switch Off - What You Need to Know

At MES Systems, we understand the importance of staying informed about the latest developments that can affect your security and communication systems. A few years ago, we wrote a blog post discussing the upcoming PSTN and ISDN 2025 switch off. As the switch-off date draws closer, we wanted to provide you with an update and address the recent surge in inquiries we've been receiving regarding this topic.

To ensure a smooth transition for our valued customers, we've gathered the most relevant information and have introduced new services to adapt to the changing landscape of communication technology.

Understanding the PSTN and ISDN Switch Off
The Public Switched Telephone Network (PSTN) and Integrated Services Digital Network (ISDN) have served as critical communication infrastructures for decades. However, with advancements in internet-based technologies, the decision to phase out these traditional networks was made. By 2025, most of the country will be affected by the switch off, as they transition to All IP.

Upgrade Options for Monitored Alarm Systems
For customers with monitored alarm systems, we have a range of upgrade options that utilise internet and mobile telephone networks to connect with the alarm receiving centre. This ensures that your security remains robust and reliable during and after the switch off. Explore our remote monitoring options.

Upgrade Options for Non-Monitored Alarm Systems
Depending on various factors, such as the type of system you have, your ISP, the location of your main alarm panel and the location of your master telephone socket, we may be able to assist in getting your old panel connected to your broadband router. Learn more about our intruder alarms here.
