The UK analogue PSTN (Public Switched Telephone Network) and ISDN copper infrastructure is being permanently switched off. Every traditional line in homes and businesses must migrate to IP-based digital solutions.
What is actually affected?
It's not just office desktop phones! Many organisations overlook critical equipment attached to analogue lines:
- Lift emergency alarm units
- Building red-care fire & intruder alarms
- Door entry intercom systems
- Traditional chip & pin card payment machines
- Franking machines and legacy telemetry meters
