The PSTN switch-off: don’t get cut off

The PSTN switch-off: don’t get cut off

As the 2025 deadline for the PSTN (Public Switched Telephone Network) and ISDN (Integrated Services Digital Network) switch-off approaches, water utilities, emergency services, local authorities and others are being forced to consider alternative options for transmitting voice and other data.


So how can industry prepare and maximise resiliency – and what are the options available?

Krucial’s latest e-book dives deep into the impact of the switch-off on industry and the reason a hybrid communications solution could be the answer – including use cases to demonstrate how that would work in practice. Our free webinar will also seek to answer questions about what this means for businesses moving forward – including expert analysis from guest panellists.

PSTN has been the basis for the UK phone network for decades, so innovation and fresh thinking will be required for those looking to digitize operations post-PSTN.

Resiliency is also crucial to any replacement for emergency services reliant on a robust infrastructure to communicate with crews immediately, regardless of conditions.

For those living in cellular-denied areas, any solution must still work even in the event of a power cut. BT is planning to go to a ‘digital voice’ (which will go down in the event of a power cut) and full fibre service to digitize the infrastructure, but in many areas that remain unavailable (and expensive to install).


Krucial CONNECT is the resilient alternative your business needs.
