The countdown is on to the PSTN Switch-off where the UK’s ISDN and PSTN networks will be switched off permanently and many legacy technologies will no longer work.
Can you beat the clock in our 90 second game and identify all of the areas of your business that could be affected? Play the game now to find out!
In 2025, UK’s ISDN and PSTN networks will be switched off permanently and many legacy technologies will no longer work.
The aim of the game is to find and select as many day-to-day objects as you can which will be affected by the upcoming PSTN Switch-off.
Navigating
Starting from the top floor, click on only the objects that you believe will be impacted by the PSTN Switch-off, as you make your way down each floor.
The end
The game concludes when you hit the ‘Submit’ button at the bottom of the office block, or when the timer reaches 2025, whichever occurs first.
Results
You will then be presented with your results, and have the chance to find out more detail about the objects that you correctly identified, and those that you missed.
Instructions
Click all the objects on each floor that you think will be affected by the PSTN Switch-off. On each selection, the timer stops and an explainer pop-up appears. Click continue to restart the timer.
And when you have found them all scroll down to the next floor.
