The big switch off
Ready for the big switch off?
Back in 2017, Openreach announced the shutdown of the old analogue phone network, PSTN and ISDN.
That means any services running on traditional copper phone lines, including some broadband connections, will stop working unless upgraded.
Whether you’re already planning your switch or just getting started, our experts are here to help. We’ll walk you through your options and how to future-proof your network.

PSTN Charter
Nasstar fully supports the PSTN Charter and is committed to protecting vulnerable end users throughout the transition to digital landlines.
By following Ofcom guidance and providing reliable upgrade solutions, we aim to ensure a safe and responsible PSTN switchover.
This approach guarantees that end users who rely on telecare or alarm systems are not transitioned without appropriate support and compatible technology.
Learn more about the Government’s PSTN Charter and how it protects vulnerable customers.
Critical National Infrastructure Charter
Nasstar supports the PSTN Critical National Infrastructure (CNI) Charter by prioritising circuits used by essential services and working closely with customers who rely on legacy PSTN or ISDN connectivity.
We identify dependencies, plan transitions in advance, and ensure that services are not disconnected without explicit consent and prior notice.
Through dedicated support, equipment testing, and collaboration with asset owners and vendors, we help maintain the resilience and continuity of critical services throughout the PSTN transition.
