Preparing for the BT PSTN Switch-Off: A Guide for Businesses

The UK’s Public Switched Telephone Network (PSTN) has been the backbone of our phone system for decades. However, as technology evolves, so must our communication infrastructure. BT has announced plans to switch off the PSTN by January 31, 2027, replacing it with a fully digital network. In this article, we’ll explore what this means for businesses, what steps you should take, and the benefits of embracing the new digital services.

What’s Happening?

  1. The Transition: BT is moving all its customers from the old analogue PSTN to a fully digital network. This transition involves routing calls over IP (Internet Protocol) rather than traditional phone lines.
  2. Deadline: Openreach, the infrastructure provider, plans to stop the PSTN (and ISDN) service by 2027. By then, every phone line in the UK will be digital.
  3. Everyone Is Affected: This change impacts both businesses and homes. But it’s not just about phone services; it also affects non-voice services connected to PSTN or ISDN lines, such as alarms, EPOS machines, door entry systems, CCTV, and faxes.

Why the Switch?

  • Outdated Technology: The PSTN network is essentially a 20th-century technology. As communication demands increase, it struggles to keep up. We now need more than what traditional phone lines can deliver.
  • Embracing Digital: IP-based communication offers boundless possibilities for UK businesses.

Stop Sell

In September 2023, BT Openreach stopped accepting new orders for broadband or PSTN services that use the old copper network. This includes ADSL, FTTC, ISDN and WLR lines.

Instead, services will be based on FTTP or SOGEA, or, if these are not available, on Single Order Temporary Access Product (SOTAP) – the replacement for ADSL if FTTC (and thus SOGEA) or FTTP are not available.

What Businesses Should Do

  1. Review Your Systems: Identify all services connected to PSTN or ISDN lines. This includes alarm systems, EPOS terminals, and other non-voice devices.
  2. Transition to IP: Consider moving your communications to the C Use VoIP (Voice over IP) for calls and explore video conferencing options. IP systems offer scalability, flexibility, and advanced features.
  3. Alarm Systems: Many alarm systems rely on PSTN lines. Consult with your alarm provider to ensure compatibility with the new digital network. Upgrading to IP-based alarm systems may be necessary.

Benefits of Digital Services

  • Flexibility: With digital communication, you can make and take calls from any device, anywhere, using the same number.
  • Cost Savings: Combining phone service and internet access reduces costs. Plus, digital services are often more affordable.
  • Advanced Features: Enjoy call analytics, customisable hold messages, and seamless integration with other digital tools and business apps.

The BT PSTN switch-off is inevitable, but businesses can prepare by understanding the changes, reviewing their systems, and embracing the benefits of digital communication. Start planning today to ensure a smooth transition to the future of telephony.
