You know it’s going to happen, but have you considered what exposure or risks the ISDN / PSTN switch-off poses to your organisation?

Proactive planning now, will address any potential issues and help you minimise disruption

“Switch On to the Switch Off” survey

According to the “Switch On to the Switch Off” survey in March 2021, 83% of organisations indicated they had no visibility of when their services would be switched off and 46% have no idea that their existing analogue phone and ISDN services will be switched off completely by December 2025.

ISDN (Integrated Services Digital Network) is a telephone network that allows both voice and data services to be delivered over digital lines simultaneously, while PSTN (Public Switched Telephone Network) is the older analogue telephone network. These ageing infrastructures use underground copper telephone lines and old signalling methods which are planned to be completely switched off nationally by 2025.

The wide-reaching effects of the ISDN / PSTN switch off

Due to the number of telephone exchanges, this involves in the UK, this will be an ongoing programme affecting all main carriers, not just BT, with a significant number of the changes happening from 2022 onwards. 77% of organisations surveyed said they have not prepared for any disruption the switch off of these services may cause.

This change will not just affect voice calls, but security, well-being and any equipment reliant on these services the longer actions are delayed, the more problematic the situation may become, accentuated by several factors which could intensify the complexity of the switch-off, for example:

  • The number and location of sites involved
  • The number of suppliers involved
  • Availability and accuracy of records kept
  • Resource, expertise and legacy knowledge available in-house
  • Variation in applications, which may result in more bespoke solutions being needed
  • Long contract durations restricting options
  • Electrification for any new solutions needed and/or the availability of network coverage
  • Space / storage requirements
  • Budget planning to cover the cost of any changes needed
