Hollow-Core Fibre: The Route to a Faster Future?

As the UK's ageing copper landline network becomes increasingly unstable, Cambridge Management Consulting reports that BT is urging Critical National Infrastructure (CNI) providers to expedite their transition from analogue to digital voice. With the Public Switched Telephone Network (PSTN) nearing the end of its life, organisations face significant risks if they delay planning and execution for this essential upgrade. Recent data indicates that 60% of CNI providers in the UK still lack a strategic plan to migrate from the legacy analogue network. This statistic underscores an urgent need for action to safeguard essential public services, such as healthcare, water, energy, emergency services, and government operations. The transition is not merely a technological upgrade; it is a once-in-a-generation programme to future-proof communications and improve service reliability. The PSTN, our communications backbone for over a century, is becoming increasingly prone to faults and difficult to maintain, with recent reports showing a 45% increase in significant resilience incidents. The impact of this transition is wide-reaching, affecting critical systems such as telemetry monitoring sensors, emergency phone lines, telecare alarms in hospitals and care homes, CCTV, intruder and fire alarms and older EPOS machines.  As the below graphic shows, a broad spectrum of devices and services will be affected by the analogue switch off, including ISDN, ASDL and Fibre to the Cabinet (FTTC) broadband services. The majority of organisations are almost certainly in the dark when it comes to common knowledge of all of the devices affected, lacking the internal expertise and records to identify and audit complex, interrelated legacy systems.

Well Intended Guidance Leaves more Questions than Answers The UK Government Digital Services – part of the Department for Science, Innovation and Technology – has recently published guidance for how the public sector should adopt a multi-region approach to cloud technology. At first sight this appears encouraging. Any unnecessary constraints on hosting arrangements (or any other non-functional requirements) reduce the available market of providers, constrain competition, and therefore inevitably reduce value for money. If parts of Government, whether central, regional or local, have felt that everything must be hosted in the UK then it makes sense to produce guidance that clarifies this perception and helps to open their options up. But for guidance to be useful it should guide. It should make it easier for people to take actions that they previously would have discounted. The guidance in this case, which at 1420 words is almost as short as this article, probably leaves the reader with more questions than answers. It may reveal some unknowns, but without increasing certainty. The Guidance in a Nutshell A summary of the guidance is as follows: Look wider than UK: Many cloud solutions may not offer UK hosting, particularly new innovative solutions that haven’t scaled up yet. Irrespective, their staff are likely to be distributed around the world if the service is supported 24/7. There may also be other benefits in looking wider than UK hosting, such as enabling better business continuity and disaster recovery options if the vendor only has one UK site. Get legal advice: Before you even consider a non-UK option you need to seek advice from your own legal advisors and your Data Protection Officer (DPO). Ensure compliance with ICO guidance: Before you even consider a non-UK option you need to check and make sure that any international transfer of personal data will be compliant with the Information Commissioner’s Office (ICO) guidance, and you should get further guidance from your own legal advice and DPO. Do a full review of vendor security: Before you even consider a non-UK option you need to make sure the vendor and solution are compliant with your own security policies. In a nutshell, it says: 'you should consider options outside of the UK but only if you have checked everything is legal and secure'. This seems to be verging on a statement of the obvious; the real difficulty in going offshore is covering all of the legal, regulatory and security compliance aspects. Adequacy is a Moment in Time On point 3, the guidance points out data protection compliance is easier if the country in question is considered by the ICO to be adequate – having equivalent regulations for data protection to the UK. Sound advice. But even this is not that simple. For instance, the USA is not considered adequate unless it is under an extension of the EU-US Data Privacy Framework. This framework is dependent on an Executive Order that the Biden administration put in place, and it is entirely possible that it will be revoked by the current administration. If such an action was taken, or if for any other reason the EU decides that adequacy is no longer met (also not unlikely given Herr Schrems has achieved this twice already and has stated he plans to challenge the DPF), then the vendor will no longer be considered compliant. Consideration is Far Wider than Residency Security is far wider than data residency though. This is where point 4 both states the obvious and understates the complexity. Managing risk in the supply chain is inherently difficult. Cloud providers, and particularly SaaS solutions, aggravate this challenge by an order of magnitude. By their nature they are solutions designed for a broad and varied range of customers. This means they will always involve compromise. If they tried to meet the most demanding requirements, they would price themselves out of the scale marketplace. If they went for the lowest common denominator, they would be unable to meet the requirements of the majority. An individual customer can rarely dictate a specific security requirement for themselves. They are also highly opaque. The vendor presents their service as a black box. The features delivered to the customer are defined, but much of the underlying design and the means the vendor uses to manage it in operation are hidden. This makes assessing the risk far more of a judgement call than when the design and delivery is conducted under your control. Depending on the supplier, and the leverage that the customer has over them, it may be possible to get some information and assurances; but the right questions need to be asked, and the answers need to be interpreted correctly. Third party certifications and audits, such as the ISO27000 series of standards or the SOC1, SOC2 and SOC3 reports, can also provide some additional assurances. But only the customer will be able to decide the extent to which they can mitigate the risk, and the confidence they have in the supplier to manage their own. This is a business decision informed by the specifics and nuances of the risks being considered. Summary It is important to minimise the non-functional requirements and keep an open mind about potential solutions and vendors. This includes looking wider than just the UK when national security requirements are not paramount. But this is not something that can be distilled onto a single sheet of A4 in any meaningful way. Yes, there are legal and regulatory issues that need to be reviewed. And geopolitical risk needs to be factored in, considering how you would respond to future external changes that are outside of the UK’s control. But from experience, the greatest challenge is getting comfortable that the vendor’s organisation and their solution have adequate security – this applies equally whether the solution is hosted in the UK or overseas. The SaaS world is opaque, and balances priorities across a broad and varied customer base. The public sector needs to increase its adoption of cloud and SaaS solutions to remain efficient and relevant, in the same way that the private sector has had to. But the route to responsible adoption is more nuanced, requiring candid conversations with suppliers, and ultimately an informed but subjective judgement by the customer’s leadership.

The Digital Communities All-Party Parliamentary Group (APPG) shared the ‘Care to connect: Public Switched Telephone Network (PSTN) Migration’ report with key parliamentarians on Monday at a launch meeting on Parliament Street. This report highlights key recommendations for managing the ongoing Public Switched Telephone Network (PSTN) migration, focusing on protecting vulnerable residents and ensuring effective solutions. Here are the major takeaways for local government and communication providers: Data-Sharing Agreements (DSAs) DSAs between communication providers (CPs), local authorities, and telecare providers are crucial for identifying vulnerable residents during the migration. Challenges include inconsistent responses from local authorities and fragmented approaches across CPs. The APPG recommends all local authorities and housing associations sign DSAs, regardless of progress in digital switchover, to promote uniformity and resident safety. Telecare Devices The sale of analogue telecare devices must end, as these can leave residents unsupported during the transition. The government, in collaboration with the TEC Services Association (TSA), should enforce higher standards (TEC Quality’s Quality Standards Framework) across the telecare industry to achieve robust digital migration practices. Financial support for local councils is critical to replace outdated telecare devices and prevent double costs. Battery Backup Solutions Existing guidance from Ofcom, requiring one-hour resilience for power cuts, is insufficient. The APPG recommends increasing power backup requirements to at least 4 hours in homes and 6 hours for fixed networks. Communication and energy providers must jointly create resilient power solutions, particularly for vulnerable residents reliant on telecare devices. A multi-sector priority service register should integrate communications and energy service protection for those at risk. Sunset of 2G and 3G Networks UK mobile network operators plan to stop supporting 2G and 3G networks by 2033, with some networks already switched off. There are cases where local authorities and residents have purchased telecare devices using 2G/3G SIM cards, as a lower-cost, interim solution — these devices will need to be replaced again, posing double replacement costs for local authorities and additional risks to residents. The government should stop the sale of analogue devices and accelerate efforts to prevent the redeployment of outdated telecare alarms. Summary We welcome these recommendations alongside the December 2023 PSTN Charter, the Telecare National Action Plan and the PSTN Non-voluntary Migration Checklist. The conclusions make it clear that coordination between local and central government, industry regulators (such as Ofcom and Ofgem), and communication providers (CPs), as well as significant investment in digital teams at a local level, are essential goals to ensure a safe and inclusive digital switchover for all vulnerable residents and telecare users.

What Do Your Scope 3 Emissions Have to Do with Inflation? Scope 3 emissions cover everything outside your direct operations —the carbon footprint of your supply chain, purchased goods, logistics, business travel, and more. The higher your Scope 3 emissions, the more energy-intensive your supply chain is. And the more energy-intensive your supply chain, the more vulnerable you are to rising costs. Think of it this way: High Production Costs- If your suppliers are heavily dependent on fossil fuels, their production costs are rising fast Price Volatility- If your supply chain lacks efficiency and resilience, price volatility will hit you harder Locking in High Costs- If you’re not actively engaging with suppliers to reduce emissions, you’re locking in long-term cost increases that could have been avoided Without accurate Scope 3 data and a clear engagement strategy , businesses are leaving themselves open to higher prices, lower margins, and greater financial risk . Why Businesses Struggle with Scope 3 A major challenge is that Procurement and Sustainability teams often operate in silos: Procurement teams focus on cost and supplier relationships but often lack deep sustainability expertise Sustainability teams focus on compliance and decarbonisation but aren’t typically measured on financial performance This disconnect means emissions reduction is rarely treated as a financial opportunity —when in reality, cutting carbon from your supply chain is also one of the most effective ways to reduce exposure to cost inflation. The Businesses That Get This Right Will Lower their Costs Leading organisations are already taking action. They are: Gathering detailed Scope 3 emissions data to map out cost risks in their supply chain Engaging suppliers to drive efficiency, reduce emissions, and lower costs Building resilience by shifting towards lower-carbon, more cost-stable alternatives The result? Lower long-term costs, reduced financial risk, and a competitive edge over those stuck with inefficient supply chains. This is not just about sustainability compliance —it’s about smart financial decision-making. If You’re Not Taking Action, You’re Losing Money Every business will feel the impact of rising supply chain costs—but not every business will be prepared for them. If you don’t have accurate Scope 3 emissions data and an effective engagement strategy, you are: Paying more than you need to for essential goods and services Exposing your business to long-term cost inflation Missing out on opportunities to build a stronger, more resilient supply chain The sooner you act, the better the outcome for your bottom line and the planet.

Peter Drucker wrote in his book The Practice of Management (1954) that ‘it is the customer who determines what a business is’. This sentiment still firmly holds true today, as consumers increasingly expect personalised shopping experiences from aspirational businesses that desire to have a positive impact on the community, country, or world in some way. Across this series of articles, Daniel Fitzsimmons explores the role of customer-centricity as a mechanism to support the delivery of superior customer experience and business profitability. In the first two articles in this Customer Centricity series, Daniel has established the foundations of what makes a truly customer-centric organisation, and how a business can be tailored towards ensured customer satisfaction. In the final article in the series, he takes this further to discuss how technological innovation can amplify these goals. Digital Transformation – Technology Acceptance Model (TAM) Technology is typically the most common interaction point for customers engaging with products, and is especially critical to the service industry. The banking industry has pioneered the digitalisation of services (Dube and Helkkula, 2015), with digital payment services and blockchain solutions. In a fiercely competitive environment, the creation of superior value requires increased insight into how customers experience value (Medberg and Heinonen, 2014). Value can be typically defined as the ‘consumers’ overall assessment of the utility of a product based on perceptions of what is received and what is given’ (Zeithma, 1988). This concept can be extended to a value definition in the following forms: Total Monetary Value – The amount a customer is prepared to pay for a product Perceived Use Value – Defined by a customer’s perception (utility) Exchange Value – Realised when the product is sold Value can be enhanced through digital capabilities, marking technology solutions, and digital marketing strategies to support user acceptance. Securing User Acceptance One compelling approach to understanding how users may engage with a new technology is the TAM model. The TAM model suggests that Perceived Usefulness (PU) and Perceived Ease of USE (PEOU), define how a user will interact with a new product or service, i.e. if the product usefulness and ease of use can be communication, barriers to adoption can be mitigated. When developing new customer solutions, mobilisation of the TAM model is the engagement of consumers in product development, and inclusion of then construct of ‘user intent’ to inform product ideation. Venkatesh et al. formulated the unified theory of acceptance and use of technology (UTAUT). This model was found to outperform other models (Adjusted R square of 69 percent), and is worthy of further investigation in terms of its ability to predict user acceptance of new technology solutions. Experimentation Technology should function as an enabling mechanism to support experimentation in the creation of products and services, and increased alignment with prospective customers. Experimentation, which from an engineering perspective represents ‘continuous improvement’, allows businesses to see what does and doesn’t resonate with target personas, iterating towards a value proposition that will drive superior customer engagement and subsequently an increased % of the customer wallet. Booking.com runs more than 1,000 tests simultaneously to fine tune its offering specific to a user profile, behaviours, and characteristics. Experimentation and the subsequent data generated provides a meaningful base from which to make decisions, thereby negating ‘strong opinions or the HiPPO mentality, which is often pervasive in organisations. For experimentation to be successful, leadership needs to create a culture of curiosity in the business, supported by organisational design and the psychological safety to try and fail. Digital continuity provides an exciting opportunity to enhance the customer voice in product development. Real time data availability provides instant insight into consumer preference, which can be used to support product development and increasingly personalised product offers. Through the experimentation cycle, digital prototypes can be rolled out quickly to support the product innovation cycle. For experimentation to be successful, customer requirements should be integrated into business operations to create an industry-aligned value proposition (Ohmae, 1988). Conclusion Throughout this three-part series, I have demonstrated the importance of customer-centricity as a critical way to ensure success. In this article specifically, I have covered how to leverage technology – a power that is already prevalent and constantly evolving – to best support this venture. Building upon the TAM model, technology can be used to facilitate enhanced customer satisfaction, consequently spurring innovation and growth.

In my discussions with building owners and occupiers about property technology, the conversation often centres on leveraging new technologies and existing data to enhance compliance, reduce costs and carbon emissions, and improve workplace experience. Many people in the property sector share a common concern around the quality of data currently held on their buildings. This gap in record-keeping could pose significant challenges as the UK's Public Switched Telephone Network (PSTN) is retired in early 2027.  PSTN is the analogue telephone network that carries voice and data over copper wires. This legacy infrastructure is becoming increasingly costly and difficult to maintain, and it is unable to handle the data demands of modern telecommunications. As a result, BT and other UK phone companies intend to withdraw PSTN services by the end of January 2027. Although records may not show it, many buildings rely on PSTN lines for critical services such as lift emergency calls, fire alarms, security systems, door entry monitoring and building management systems. Once PSTN is decommissioned, these services will cease to function without warning, potentially leading to safety compliance and security risks. To mitigate these risks, building owners should proactively assess their exposure before PSTN services are discontinued. Identifying and replacing existing PSTN connections with future-proofed, and potentially more cost-effective, digital solutions is essential for business continuity. Building occupiers should also seek assurances from their landlords regarding these transitions. At the Connected Britain Conference last year, the Minister of State for Data Protection and Telecoms, Sir Chris Bryant MP, highlighted the vital importance of digital infrastructure and cited the PSTN switch-off as a significant concern. BT recommends that its business customers act before the end of 2025. The transition to digital alternatives including testing and commissioning could take 6-9 months. A critical first step is to carry out an audit to identify systems that rely on PSTN. This audit should identify all devices connected to the PSTN, their locations, their functions, and upgrade options. I have been urging property owners and operators to develop and implement a programme of discovery and rectification as a priority. Without early and rigorous planning, the risks to safety, business continuity, and occupier experience are high. Also, as the switch-off date approaches, the costs of this work are very likely to increase significantly. Cambridge Management Consulting has a team of PSTN experts, who can identify existing PSTN-based systems, procure replacement solutions and migrate your services, as well as identifying and implementing cost reduction strategies that become possible through the transition to digital solutions. We can also ensure your organisation avoids the risks to compliance, security and occupier experience when PSTN services are withdrawn as well as reaping the long-term benefits of going digital.
