The End of an Era: The PSTN Switch Off and the Rise of Digital Telephony

In a world where technology advances at a breathtaking pace, even the most steadfast institutions must eventually yield to progress. One such institution, the Public Switched Telephone Network (PSTN), has long been the backbone of telecommunications. However, as we march further into the digital age, the time has come to bid farewell to this venerable system.

The PSTN, born out of the earliest days of telecommunication, has served us faithfully for over a century. Its inception marked a revolution in communication, enabling people to connect across vast distances in ways previously unimaginable. From Alexander Graham Bell’s first telephone call to the seamless global networks we rely on today, the PSTN has been there every step of the way.

Yet, as with all things, the PSTN has reached the end of its lifecycle. The infrastructure that once represented the pinnacle of communication technology now struggles to keep pace with the demands of a rapidly evolving digital landscape. Analog systems are inherently limited in their capacity and flexibility, unable to support the data-intensive services and functionalities that modern users expect.

The decision to retire the PSTN was not made lightly. It marks the end of an era and requires careful planning to ensure a smooth transition for businesses and consumers alike. However, the benefits of this transition are undeniable. By moving away from outdated infrastructure and embracing digital alternatives, we unlock a world of possibilities for innovation and progress.

Digital telephony, built upon Internet Protocol (IP) networks, offers a wealth of advantages over traditional analog systems.

Stop Sell September

Whilst there’s a chance of sounding repetitive, it’s essential to highlight the forthcoming PSTN stop sell. The PSTN, or Public Switched Telephone Network, has served as the backbone of our telephone and broadband connections in the UK for many years. However, its days are numbered, and a transition away from it is on the horizon. Although the complete switch-off won’t occur until 2025, significant changes are just around the corner and these will affect you at the office and at home.

It’s all change

The initial phase of the PSTN switch-off involves the stop sell of services that rely on the network. This means traditional analogue telephone services (landlines) and broadband services like ADSL and FTTC will no longer be available.

You might think, “We’ve heard this all before,” and you’d be right. However, as the PSTN stop sell date approaches, it’s essential to grasp the implications.

No New Sales

For those seeking a new broadband or telephone connection, whether you’re changing providers, renewing your contract, or relocating, you’ll no longer be able to purchase any service that utilises the copper telephone network. This includes standard broadband and fibre to the cabinet options, as well as landline telephone connections.

No Changes

Even if you’re already using copper-based broadband or telephone services, making changes to your existing plan will become impossible. That means no speed upgrades or switching to a different provider. Furthermore, repairs on the copper network will decrease, potentially leaving you without service in case of a significant fault.

What else could be affected?

If you’re relying on services tied to the PSTN, such as connected alarms and CCTV, be prepared for potential disruptions. These services will need to be transitioned to the new all-digital network infrastructure.

Thankfully, service providers like Deep Blue have been diligently working to make the transition from copper services as seamless as possible. Our advanced connections utilise the UK’s fibre network and will keep you connected long after the PSTN is retired. Additionally, you’ll have access to a new form of telephony known as Digital Voice, which leverages VoIP (Voice over Internet Protocol) technology for internet-based phone calls.

If you haven’t received information about upgrading your services or want to explore your options further, call our team on 0333 240 9100 and explore Deep Blue’s broadband and Digital Voice pages. Embracing the transition now will ensure you continue to enjoy reliable and up-to-date communication services.

This is especially true of telecoms, where users demand faster, more reliable, and future-proof services. That’s why Deep Blue are working hard to move our customers onto full fibre and SoGEA broadband.

The PSTN switch off

Openreach has been planning to switch off its legacy network, including the PSTN and ISDN, for some time now. The switch-off is currently scheduled for December 2025, and this means that businesses need to start preparing for the change sooner rather than later.

At Deep Blue, we believe that the switch-off presents an opportunity for businesses to future-proof and get the most from their telecoms. That’s why we’ve been encouraging our customers to make the switch to full fibre and SOGEA services. These services not only offer faster speeds and greater reliability, but are increasingly more cost effective than their legacy counter parts.

What are we doing to assist our customers?

We’ve already moved a number of our customers onto these services, and the feedback has been overwhelmingly positive; with improved performance and reliability, as well as cost savings. They’ve also appreciated the peace of mind that comes with knowing that they have made the move ahead of the rush as we approach the big switch off.

For those still on ADSL and FTTC we are in the process of contacting sites that can move to start the upgrade process. The next batch of upgrades is booked for the end of May and emails for those we hope to move in June will be going out shortly.

Do you need to do anything?

You do not need to do anything as we will contact you to arrange the migration process, however, if you don’t want to wait and would like to request a move sooner then you can contact a member of the team at theteam@deepbluetelecom.co.uk or on 0333 240 9100.

In Summary

The switch-off of the PSTN and ISDN networks presents a great opportunity for businesses. Full fibre and SOGEA services offer faster speeds, greater reliability, and future-proofing, they can also lead to significant cost savings. At Deep Blue, we’ve already moved a number of our customers onto these services, and we believe that they are the way forward for businesses looking to stay ahead of the curve.

Switching to VoIP: Benefits and Challenges of the PSTN Switch Off

The UK is currently in the process of phasing out the Public Switched Telephone Network (PSTN), which is a network of interconnected telephone lines and switches that has been in use for over a century. The PSTN switch off is part of the wider transition to digital communication technologies, such as Voice over Internet Protocol (VoIP).

The switch off of the PSTN is being driven by several factors, including the high cost of maintaining the ageing infrastructure, the growing popularity of mobile and internet-based communication, and the need for more efficient and cost-effective telecommunications systems.

Ofcom, the UK’s communications regulator, has set a deadline of 2025 for the complete switch off of the PSTN network. This means that traditional phone lines that rely on copper wires and fixed-line telephony will eventually be replaced by internet-based alternatives.

The switch off of the PSTN networks is expected to bring a number of benefits, including improved call quality, faster data transmission speeds, and a more reliable and efficient telecommunications system. However, it may also create challenges for some users who rely on traditional phone lines, particularly in rural and remote areas where internet connectivity may not be readily available.

To address these challenges, the UK government is working to improve the country’s digital infrastructure and ensure that all areas have access to reliable and high-speed internet connectivity. This includes initiatives such as the Universal Service Obligation (USO), which aims to provide every household in the UK with a minimum broadband speed of 10Mbps.

Overall, the switch off of PSTN in the UK represents a significant shift towards more modern and efficient communication technologies, but it also highlights the need for continued investment in digital infrastructure to ensure that everyone can benefit from these advances.
