ISDN Switchoff: The Details

BT have announced that they are ending support for ISDN and PSTN networks from 2025, although it is expected the transition will start in 2018.

What is ISDN and PSTN?

ISDN stands for Integrated Services Digital Network. This is a set of communication standards which enabled the simulataneous digital transmission of voice, video, data over the infrastructure and circuits of the traditional Public Switched Telephone Network (PSTN). ISDN displaced the traditionally copper fixed-line analogue telephone networks.

ISDN was an improvement over PSTN when it first arrived, as it allowed simultaneous phone calls over the same line. However, it is now soon to be displaced with new IP based telephony systems that use an IP or Internet connection to enable communication throughout an organisation, different sites, or even different countries.

There are currently an estimated 3.2 million ISDN channels in the UK. The vast majority of which are owned by BT. These will all have to be replaced or upgraded to IP based telephony systems in the coming years. While a quarter of businesses are unaware of the upcoming switchover, it's estimated that 96% of businesses who have made the change to IP-based telephony systems have benefitted from cost savings.
