Removal of Current Copper Network Affecting PSTN Communications Devices


Deleted member 24354

A recently received update from BT discusses the removal of current copper networks on an exchange basis for new IP solutions. These changes are due to start on a phased implementation from September 2020, and the latest estimates conclude this will be an ongoing project until the end of 2025.

The British Security Industry Association (BSIA) have issued a formal press release on this matter which can be read at In addition to this, the BSIA have issued a brochure outlining the changes, its importance, and the impact it will have onthe security industry which can be viewed on the Pyronix website at

When a premises communication lines are upgraded, it has the potential to cause problems on PSTN communication modems installed in control panels. These were designed to operate on the current copper cabled grids. It cannot be guaranteed that current operations will operate on the new digital networks.

Given alarm systems are often used for police calling and/or insurance policy conditions, it is important that installers assess their estate of installed security systems to ensure that they will continue in working order.

It is strongly recommend against utilising PSTN modems as a communication or signalling solution on all future installations.

It is recommend where possible, upgrading current security systems in the field to IP based communications such as Wi-Fi, LAN and GPRS solutions.
