THE UK PSTN SWITCH-OFF IN 2025. Ten myths about digital phone lines debunked

BT have recently confirmed that the switch-off of lines will now occur by January 31, 2027, rather than the original deadline of December 2025 – this includes the switch-off of Public Switched Telephone Network (PSTN) and Integrated Services Digital Network (ISDN). This delay is a significant development for customers, and we feel it is important that you understand what it means for your business.
At Trichromic we want to keep our customers informed about the latest developments in the UK’s full-fibre future. For those who are currently using analogue (PSTN) or ISDN lines for calls, alarms, fax machines, PDQ machines or, CCTV, these will need to be replaced with digital solutions at some point.

Why the Delay?

The delay is primarily due to the need to ensure a smoother transition for vulnerable customers and those with additional needs. The extra time allows for a more comprehensive approach to migrating these customers to digital landlines, ensuring they receive the necessary support and equipment to maintain their connectivity.
Specifically, the delay is a response to concerns raised by vulnerable individuals who rely on telecare devices, including personal alarms, which stopped working during the initial switch-off process. Nearly two million people in the UK currently use personal alarms which rely on landlines. Therefore, this revised timeline aims to address these concerns and provide a more stable transition for these critical services.
Additionally, the delay provides more time for BT to work with suppliers and partners to ensure a seamless transition for all customers. This includes:

1. Completing the necessary testing and validation of new digital landline solutions to ensure they meet the required standards and compatibility with existing systems.

2. Resolving any outstanding technical issues that may arise during the transition process.

3. Conducting thorough quality assurance checks to guarantee that all services are fully functional and meet customer expectations.

What does the switch-off delay mean for Trichromic customers?

While the switch-off delay is needed, Trichromic remains committed to helping all our customers to move to digital services as soon as is practical.
The delay is a short extension of 13 months, so we will continue working closely with you to ensure a smooth transition. We are committed to providing ongoing support and guidance from our team as we work together to migrate your services.

What’s next?

The big switch off will happen and we have 2 pieces of advice for our customers:

1. Digital services are available now and, as we have pointed out in previous posts, the service is better than the current (analogue) system.

2. Don’t wait. We anticipate a clamour of users wanting to move to a digital service as the deadline date approaches. You really don’t want to be left behind.

We will continue to keep you up to date on future developments with the PSTN switch-off and any changes that may affect your services. If you have any questions or concerns, please don’t hesitate to reach out to our team – we are here to support you every step of the way.
