2025 ISDN & PSTN Switch Off

The world of telecommunications is undergoing a significant transformation. The traditional methods of communication, such as the Public Switched Telephone Network (PSTN) and the Integrated Services Digital Network (ISDN), which have been the backbone of business communication for decades, are becoming obsolete.


Why Switch Off ISDN & PSTN?


The PSTN and ISDN, introduced in the late 1800s and 1986 respectively, were once revolutionary technologies that transformed the communication industry. However, with the rapid advancements in digital communication technologies, these networks have become more of a hindrance than an aid to businesses.


The ISDN & PSTN switch off, scheduled for December 2025, marks the end of these outdated networks. Openreach has been gradually switching off these networks across the UK and encouraging businesses to migrate to newer technologies to avoid any disruption in their services. The replacement of copper with fibre optic cables is being done in phases, with all copper lines expected to be switched off by December 2025.


The Impact of the ISDN Switch Off


The switch-off will affect legacy technologies such as the Asymmetric Digital Subscriber Line (ADSL) and Fibre to the Cabinet (FTTC) broadband, which rely on the now-dated ISDN and PSTN infrastructures. As a result, businesses are urged to adopt newer technologies like VoIP or devices with an IP mode.


According to a report by The House of Commons Library, there are currently about 2.4 million businesses in the UK still operating on the outdated ISDN and PSTN. These businesses need to start their technology migration plans as soon as possible to avoid any delays or interruptions in their operations.


The switch-off of ISDN and PSTN is a significant step forward in the growth of business communications. It represents a shift from traditional methods to more advanced, internet-based technologies. This transformation will not only enhance the speed and reliability of business communication but also open up new opportunities for innovation and growth.
