The UK PSTN network is being permanently switched off. Most councils and school estates know this in principle. What many don’t realise is how much of their estate may still be quietly dependent on analogue copper infrastructure - even where services have previously been “upgraded to fibre.”
If you manage multiple schools, council buildings, care sites, depots or community centres, this is where the real risk sits.
When people hear “PSTN switch-off”, they think office phones. In reality, analogue dependency often sits behind:
• Fire alarm signalling
• Intruder alarms
• Lift emergency lines
• Door entry systems
• Careline & telecare units
• CCTV backhaul
• Legacy fax or admin systems
• Certain broadband circuits
In large estates, some of these may have been installed 10–20 years ago and never reviewed.
If no one has conducted a structured dependency audit across your sites, there is a strong chance you have exposure.
Many sites believe they are “on fibre.” But what does that actually mean? There is a critical difference between:
• Fibre runs to the street cabinet
• The final connection to the building is still copper
• Often historically paired with a PSTN line
Even if the voice line has ceased, some services still rely on legacy copper infrastructure.
Single Order Generic Ethernet Access removes the need for a traditional PSTN voice line - but it still uses the copper pair for the final connection.
For some sites, SOGEA is a sensible interim solution.
For others - particularly high-dependency environments like schools and council HQs - it may simply be delaying a move to full fibre.
• Fibre runs directly into the building
• No copper dependency
• Future-ready infrastructure
This is fundamentally different.
Dedicated Ethernet leased lines provide:
• Symmetrical speeds
• Service level agreements
• Greater resilience
• No PSTN reliance
• Business-grade uptime
For larger schools, central offices, civic buildings or data-heavy environments, this often makes strategic sense.
Across multi-site estates we commonly find:
• Mixed connectivity types across buildings
• Different contract end dates
• Unknown legacy alarm dependencies
• Incomplete documentation
• “It works so leave it” assumptions
When multiplied across 20, 50 or 200 sites, the operational risk compounds quickly. And public sector estates cannot afford disruption.
At Connection Worx, we bring 18+ years in UK telecoms infrastructure - particularly within complex multi-site environments.
We can help councils and schools:
• Map every circuit across the estate
• Identify PSTN and copper dependencies
• Clarify FTTC vs FTTP vs SOGEA vs leased line
• Highlight contract renewal risks
• Create a staged migration roadmap
• Avoid panic upgrades at the last minute
Our approach is simple:
Review first.Identify risk. Build a phased plan. Strengthen resilience.
No pressure. No unnecessary spend. Just clarity.
As you know, resilience in public services isn’t optional. Your digital network is as critical as your physical infrastructure. If you manage a council estate or school portfolio and haven’t had a structured PSTN and connectivity review in the last 24 months, it’s worth having a conversation.
A short estate-level review now could prevent significant operational disruption later.
Let’s make sure your networks are as resilient as the communities you serve.
