What is the PSTN Switch-Off?
The PSTN switch-off marks the UK’s transition to an all-digital communication infrastructure, with analogue phone services set to be fully phased out by 2027. As part of this upgrade, traditional telephone sockets are being replaced with Smart Routers to better support today’s consumers, their smart devices and apps.
So far, over 7 million phone lines have been upgraded, with another 7 million still to be completed. By January 2027, the transition will be complete, impacting millions of premises and requiring upgrades to maintain service continuity. CSL is here to guide you through every step, offering solutions to ensure uninterrupted, compliant connectivity.
