They use the network to dial out to ARCs when there are alarm signals to send and, once a customer switches to the new digital phone service, there will be no way for these solutions to perform their intended task, rendering them obsolete and the customer unprotected. So, why does this matter to alarm signalling? Because it’s not just telephones that rely on the PSTN, legacy alarm signalling solutions do too. As such, Openreach is withdrawing support and all connections will need to be fibre-to-the-cabinet (FTTC), Fibre to a point nearer the premises with copper used in the ‘last mile’, or fibre-to-the-premises (FTTP), a fibre connection all the way to the premises. However, the PSTN is reaching its end of life with the copper lines no longer sufficient to provide for the growing demand for faster connectivity and higher bandwidth. These have worked side-by-side with fibre offerings to provide telephone and internet services. traditional phone lines), which are used to carry the analogue signals for legacy voice communication. For decades, the PSTN has supported several wholesale products, such as the Wholesale Line Rental (WLR) suite (e.g. In other words, it provides the infrastructure that keeps everything connected and working. Openreach looks after the fibres, wires and cables that connect the country including the analogue phone network known as the PSTN. What is the PSTN switch-off and why is it important to installers? Therefore, in this article, we’ll take a step-back to fully explain what the PSTN switch-off means, how it will impact installers, what steps they can take to ensure the burden is alleviated through their ecosystem, and how they can truly add value to end-customers by keeping them safe and secure now and in the future.
They hold the keys to the UK’s safety and security and yet they are the party most burdened with the change. For the installers, however, changing solutions can mean new training, equipment, suppliers and so much more. That’s because they engage with an installer who handles it all for them – the process remains relatively straightforward.
While the devices themselves have evolved, the process of installing and getting them operational hasn’t hugely changed for the end-user. These devices are smarter and faster and, crucially, will continue to perform past the switch-off of the PSTN by 2025, unlike the many legacy solutions that are still in use. Today, we look at a new landscape, one that is compiled of all-IP solutions that provide always-on connections via IP and/or mobile connectivity. From bells-only systems and 999 diallers, to connected modems and devices that rely on the public switched telephone network (PSTN), the evolution of alarm signalling has seen many versions come and go.
