# Industry News: BT Urges UK CNI to Abandon Copper by 2025 for Resilience
## Summary
BT is strongly pressuring the UK's Critical National Infrastructure (CNI) sectors, including healthcare, energy, and government, to migrate away from the ageing analogue Public Switched Telephone Network (PSTN) copper infrastructure by the end of 2025. This urgent call is driven by a sharp 45% increase in reported PSTN resilience incidents in 2024, highlighting significant operational and security risks associated with outdated technology.
## Key Details
- Date: Announced around January 28, 2025 (based on article timestamp)
- Companies Involved: BT (leading the push), UK Critical National Infrastructure (CNI) sectors.
- Category: Infrastructure Modernization/Mandate for Digital Resilience
## The Story
BT, as a major provider, is advocating for an accelerated decommissioning of the legacy copper network used by CNI organizations. The PSTN is proving increasingly fragile and difficult to maintain, evidenced by a substantial rise in reported faults. Essential services relying on this infrastructure—such as water monitoring sensors, alarm systems (fire/lift), emergency road phone lines, and older payment terminals—are at risk. BT CEO for Business, Bas Burger, stressed that relying on this "fragile" network for essential public services is too great a risk and emphasized the need for a collaborative transition to modern, future-proofed connectivity well before the analogue network's scheduled closure.
## Business Impact
### For the Companies Involved (CNI Providers)
- **Operational Risk Mitigation:** Immediate reduction in the risk of outages or failures affecting physical operations due to copper line degradation.
- **Modernization Investment:** CNI sectors must allocate capital expenditure and resources for rapid migration projects, likely involving deploying IP-based or fiber solutions.
- **Compliance/Resilience Improvement:** Accelerated compliance readiness concerning national security standards for operational technology (OT) integration.
### For Competitors
- Competitors offering modern network solutions (e.g., fiber, 5G private networks, or advanced IP telephony systems) stand to benefit significantly from this state-backed call for modernization, potentially leading to increased sales cycles and revenue capture from BT’s customer base undergoing transitions.
### For Customers (End Users of CNI Services)
- **Improved Service Reliability:** The move to modern infrastructure should reduce communication failures impacting emergency services, monitoring, and utilities.
- **Potential Short-Term Disruption:** Migration activities for legacy systems may cause temporary service interruptions if not managed carefully.
### For the Market
- This signals a major infrastructure modernization effort in the UK, setting a firm, non-negotiable deadline for technology refresh across vital national services. It accelerates the retirement of legacy telecommunications hardware across the economy.
## Technical Implications
The transition necessitates replacing systems that rely on analogue signaling (like traditional alarms or some modems) with IP-based or modern digital communication protocols. This involves upgrading endpoints, communication gateways, and potentially integrating these services into broader IT/OT network management frameworks, increasing the digitalization footprint of OT environments.
## Strategic Analysis
- **Market Positioning:** BT is positioning itself as a proactive leader in national digital resilience, putting pressure on CNI bodies to act decisively.
- **Competitive Advantage:** For BT, successfully managing this large-scale transition for major clients solidifies their role as a strategic partner rather than just a utility provider.
- **Challenges:** The primary challenges are the sheer logistical complexity and cost of auditing and upgrading thousands of deeply embedded, often legacy, monitoring and safety devices across diverse CNI sectors before the 2025 deadline.
## Industry Reactions
- **Analyst Opinions:** Analysts likely view this as a necessary but overdue mandate, recognizing the inherent risks of relying on aging infrastructure for critical functions when advanced digital resilience is achievable.
- **Expert Commentary:** OT/ICS security experts would likely support the move as enhancing cybersecurity posture, as IP networks offer superior monitoring and security features compared to vulnerable analogue circuits.
- **Market Response:** Potential strain on suppliers of next-generation networking hardware and managed migration services.
## Future Outlook
- Expect increased scrutiny from regulators (like Ofcom or NCSC) to ensure that CNI sectors are meeting their migration deadlines.
- The next focus area will likely shift to securing the *new* digital pathways implemented, ensuring they adhere to zero-trust principles, especially where they interface with OT environments.
## For Security Professionals
This is a clear directive to prioritize the inventory and migration of all legacy telecommunication dependencies within your organization's CNI scope. Security teams must collaborate urgently with network operations to define the security parameters for new IP/digital services replacing the PSTN links, focusing specifically on industrial control systems (ICS) monitoring and remote access points that traditionally used analogue lines.
