The Great ISDN & PSTN Switch Off

Businesses and individuals who still rely on PSTN and ISDN should start planning for the switch off in 2025 and consider transitioning to Full Fibre and Next Gen Communication solutions​

What does this all mean for Business Telecoms?

Understanding the ISDN and PSTN Switch Off in the UK

The transition from traditional telecommunication systems to modern digital solutions is underway in the UK. Known as "The Big Switch Off," this initiative marks the phasing out of legacy ISDN and PSTN services. By 2025, these traditional services will be completely switched off, making way for Full Fibre products and Next-Gen Solutions.

Why the Switch?

ISDN (Integrated Services Digital Network) and PSTN (Public Switched Telephone Network) have been the backbone of the UK's telecommunication infrastructure for decades. However, with the rapid advancements in technology and the increasing demand for high-speed data and voice services, these systems have become outdated. The switch to digital is not just about keeping up with technology; it's about providing businesses and individuals with more reliable, flexible, and efficient communication tools.

What Does This Mean for Businesses?

While the switch-off might sound alarming, it's an opportunity for businesses to upgrade and future-proof their communication systems. Transitioning to Full Fibre broadband and other Next-Gen Solutions not only ensures continuity in services but also offers numerous benefits:

  • Higher Quality: Experience clearer voice calls and faster data transfer rates.

  • Flexibility: Use services like VoIP (Voice over Internet Protocol) to make calls from anywhere, anytime.

  • Cost-Efficiency: Digital solutions often come with cost savings in the long run.

  • Advanced Features: From video conferencing to integrated CRM systems, modern solutions offer a range of advanced features.
