The PSTN and ISDN switch-off: what it means for you
Traditional phone lines aren't just for making voice calls. There are also various products and services called special services that use these lines, such as alarms, EPOS machines, door entry systems, CCTV, fax machines, and more.
If your broadband relies on a traditional phone line, you may also need to upgrade this too.
The Integrated Services Digital Network (ISDN) will also stop working when the PTSN switch-off happens.
