The switch off means that the existing copper wires and fibre-optic cables will still be in place, but they will be used to transmit digital signals instead of analogue signals. Over time, the analogue network will no longer be maintained, leading to degradation of its ability to transmit analogue signals. If something breaks in the analogue network, it will not be repaired.
Businesses heavily rely on PSTN and ISDN for various services, including landline phone systems, internal phone systems, fax services, alarm systems, gate entry systems, lift lines, CCTV systems, and some internet connections. After the switch off, these services will not be reliable or available.
To ensure a smooth transition, businesses affected by the switch off will be contacted by service providers to discuss necessary steps and identify alternative solutions that meet their specific needs while minimising disruption to operations. It is crucial to prepare for the switch off well ahead of the 2025 deadline.
Going digital offers several benefits, similar to the introduction of broadband. Early adopters will gain a competitive advantage, while those who lag behind may lose out. By embracing digital telephony early, businesses can avoid anticipated problems associated with the switch off, such as the inability to augment or upgrade existing PSTN and ISDN services, bottlenecks, lengthy waits during the switchover, and potential equipment shortages.
