The PSTN Switch Off: A New Era of Digital Communication

by Eleasha Hylton-Rowe | July 4, 2024

Understanding the PSTN Switch Off

The Public Switched Telephone Network (PSTN) has been the backbone of global telecommunication since the late 1800s. This traditional circuit-switched telephone network has facilitated reliable voice communications worldwide for over a century. However, the technology landscape is rapidly evolving, and the PSTN is becoming obsolete. The switch off from PSTN to digital networks like Voice over Internet Protocol (VoIP) marks a significant technological shift, aiming to modernise and enhance communication systems.

How PSTN Lines Work

PSTN operates through a complex infrastructure that includes telephone lines, fibre optic cables, switching centres, cellular networks, satellites, and cable systems. This network allows landline telephone calls to be made globally. However, as technology evolves, the need for faster, more efficient, and higher-capacity communication systems is driving the move to digital alternatives.

BT Group’s PSTN Switch Off Extension

BT Group has extended the PSTN switch off deadline to the end of January 2027. This extension ensures that vulnerable customers, including telecare users, have ample time to transition without disruption. This move accommodates those heavily reliant on existing systems while updating to more reliable digital services. Early engagement in the migration process is crucial for a smooth transition.

Don’t wait—ensure your communication systems are ready for the future. The shift to digital networks is crucial for maintaining efficient and secure operations. To find out more about the PSTN Switch Off and how APS can help, click HERE.
