BT’s analogue network in the UK, the Public Switched Telephone Network (PSTN), is shutting down after decades of service. BT plans to complete the closure by 2025. 

When an alarm is triggered at a remote site, or something unusual is detected by CCTV, a signal is sent via the PSTN phone line to a 24/7 monitored alarm receiving centre. These alert systems will need to be upgraded before the copper PSTN network is to be switched off.

Although 2025 seems so far away, it’s better to prepare for it now to avoid the risk of being stuck with an outdated security system that will be useless one day, and seemingly with no notice.
