Beat the Big Switch Off - helping to get your customers ready

The BSIA is raising awareness to alarm installers and their customer base by creating an awareness campaign regarding the rolling out of the ALL-IP campaign as the deadline gets nearer. In May 2024 the original deadline of December 2025 was extended to 31 January 2027 to allow more time for Communications Providers (CPs) to safely migrate their vulnerable customers off the PSTN.

Although the industry has been promoting these changes since 2017, the BSIA believes there remains a significant number of PSTN-connected alarm systems in the UK that have not yet transitioned with the likelihood that many end-users may not even be aware that changes need to be made or appreciate the seriousness of the deadline. 

In order to get this message out, the BSIA has created an installer toolkit to use in preparing your customers for the changeover. We have also launched a campaign, 'Beat the Big Switch Off’, encouraging end users to beat the deadline of January 2027.

Beat the Big Switch Off is endorsed and supported by NSI and SSAIB.

"Openreach do not recommend the use of ATA ports for critical lifesaving lines. Ideally, newer technology products should be used where possible on this new network."
John Livermore, Openreach


Useful tools to help your customers

The toolkit includes a letter template and a FAQ flyer that we believe cover the concerns and queries which those still on PSTN lie may have, balancing useful information with the consequence if they do not transition within time.

We have also produced a useful glossary on understanding commonly used abbreviations, acronyms and their meaning.

Also, Openreach has created a handy FAQ, and the BSIA along with industry partners, have released some useful guidance and top tips to assist with the transition.

There is also a short ALL IP status survey for both installers and ARCs which has been designed to help the Association understand the full picture of the transition as we approach the crucial stages of the PSTN switch-off. 

The UK switch-off from the PSTN telephony network and migration to ALL-IP is now scheduled for 31 January 2025. From May 2024, there are 31 months until the final legacy network is switched off and 10 million lines still to be migrated by their Communications Provider (Telephone Company) to the new Digital fibre network. This will be done by each provider independently and when they are ready.

Openreach has built a Digital Services Test Lab in London for Special Service Providers (companies that provide alarms, Telecare Devices, Monitoring Devices, Chip and Pin etc) to check which of these will work in the new environment, (Digital rather than Analogue) and understand their reliability and which will need to be replaced.


Openreach has also welcomed users of this kind of equipment for testing and has already had a number of Local Authorities in the Lab to test their equipment and form their own strategy moving forward. To date, Openreach has had over 34 visits in the Lab and would be pleased to facilitate any hardware providers or users of telephony equipment, who would like to use these test facilities.

There are 690 Communications Providers in the UK and there is a representative sample of these in the Lab, with routers and lines from SKY, TalkTalk, Zen, Vodafone, BT Consumer and BT Enterprise. All testing is done by connecting the device to a router, either via WIFI, Ethernet cable or if trying to use VoIP, via Analogue Terminal Adapters (ATA) incorporated into the router itself.

If you would like to test your equipment in the Lab or advise your hardware suppliers to do so, you can contact Openreach and book an appointment. All details can be found on Openreach's digital services lab page


Prepared for IP Voice? Take Action Now

The BSIA is urging alarm installers to take action on their alarm signalling estates in advance of the UK’s transition to an IP voice-based telephony service.

David Wilkinson, Director of Technical Services, BSIA: “We have been keeping our industry sector up to date with the changes as they have developed, and given the recent announcements from Openreach, Ofcom and communication providers, our message has escalated to a ‘call to action’ asking installers to take proactive steps to mitigate the risks of systems that may fail to operate if left unchecked.”

In support of this, the BSIA has produced a position paper on IP Voice transition in the UK.

IP Voice testing

The transformation of the UK’s telephone service from analogue to digital voice is well underway with its target completion still set to be achieved by January 2027. The Openreach initial trials of the digital access network in Salisbury and Mildenhall are underway (Jan 2020 – Dec 2022) to pave the way for the ‘learning process’ ready for the full transformation to come. 

So whilst testing of alarm signalling equipment on these emerging digital services is important, it is vital that installers/maintainers of security systems assess their signalling systems ‘estate’ with respect to any risks that the change to digital voice may identify.
