Understanding the PSTN switch-off

Understanding the PSTN switch-off

As the PSTN (Public Switched Telephone Network) reaches the end of its life, we’re urging all business and public sector customers to act now to go fully digital and safeguard their services. 
 
We’re asking customers to review their technology estates, test their devices, and switch to newer, more reliable networks by the end of 2025. 
 
The old, analogue network will be switched off for good by the end of January 2027.

  • Up to 10x faster broadband speeds

    IP technology transmits more data at faster speeds, eliminating buffering or interruptions when you have multiple devices connected.
  • Increased reliability and fewer faults

    The newer, digital technology provides five times fewer faults, as well as stable broadband speeds with full fibre delivering a more consistent connection.
  • Greater flexibility and scalability

    IP technology can handle a wider range of multimedia services, such as video conferencing and streaming, and can be easily integrated with other digital technologies and services.
