BT has urged the UK’s Critical National Infrastructure (CNI) providers to accelerate plans to transition away from the ageing Public Switched Telephone Network (PSTN), warning that the outdated system poses growing risks to essential services
Increasingly fragile and difficult to maintain, the PSTN saw a 45% rise in major resilience incidents last year, according to Ofcom’s Connected Nations report.
BT warns that delays in migrating to digital connectivity could disrupt critical systems such as fire alarms, lift phones, and even water monitoring sensors.
Industries like energy and water are leading the way in the transition away from the PSTN, with 80% and 64%, respectively, of BT’s customers in these sectors having already put a transition plan in place.
However, 60% of the operator’s CNI customers have yet to develop a transition plan.
“With the ageing copper landline network becoming increasingly fragile, it’s simply too risky to run the UK’s essential public services on outdated networks. BT is committed to moving these services onto future-proofed modern connectivity well ahead of the closure of the analogue copper network – but we can’t do it alone,” said BT CEO Bas Burger in a press release.
“We’re urging all Critical National Infrastructure providers to act now to help protect their services and reap the long-term benefits of going digital. Waiting until the analogue switch-off is too late. We’re working with customers to review their technology estate, test their critical devices and switch to more reliable connectivity by the end of 2025,” he continued.
To support the shift, BT’s specialists are helping organisations review technology, test device compatibility, and migrate to digital systems. The government has also introduced the PSTN Critical National Infrastructure Charter, to make sure of safeguards for essential services during the transition.
The move to digital networks offers a range of benefits. Faster broadband speeds, better security, and features like scam prevention and integrated calling across devices.
