How to prepare for BT's transition to fully digital communicationsBy December 2025, the traditional analogue phone network (the Public Switched Telephone Network, or PSTN) will reach the end of its life and newer digital technologies will take its place. This means that over 16 million lines and channels will be upgraded to alternative products over the next six years within the UK. In our latest blog post, managing director Gordon Christie discusses the scheduled changes to telephony and broadband services and the impact that this could have on you and your business. What services are affected? “In short, anything that is currently using a copper line. Essentially, every single Openreach service that is currently utilising copper lines will be affected. “The most apparent services are analogue telephone lines (PSTN) and digital ISDN lines but it doesn’t stop there. It’s not just about telephone services, any service that uses this infrastructure will also be impacted. This includes:
- Analogue voice telephone services and any service that use these lines including Dial-up devices.
- ISDN 2e and ISDN 30e lines which are mainly used by phone systems.
- EPOS machines, door entry systems, CCTV
- Broadband services that run over an analogue telephone line e.g. ADSL and also FTTC Fibre Broadband
