2025 PSTN and ISDN Switch Off

2025 PSTN and ISDN Switch Off

What is the PSTN and ISDN Switch Off?

The traditional telephony network, the Public Switch Telephone Network (PSTN), will reach the end of life in December 2025, meaning the network will be switched off and services will no longer be supported.

The PSTN also supports the Integrated Services Digital Network (ISDN) which is the network that supports broadband, allowing both voice and data services to be delivered over digital lines simultaneously. This will also be switched off, meaning you will need to look into alternative broadband services as well as voice.

What is affected by the switch off?

In addition to the telephony products affected by the withdrawal of the PSTN, a number of connectivity services will also be withdrawn, including Asymmetrical Digital Subscriber Lines (ADSL) and Fibre to the Cabinet (FTTC) broadband.

This is because the underlying line product is being withdrawn, therefore there is no underlying telephone service to support the broadband.

 Does this effect me?

If you are still using a traditional landline and or haven’t changed your broadband recently from FTTC/ADSL you are effected by this. If you are unsure ask your broadband provider or a recent bill. If it says FTTC or ADSL or you are paying per call you are on PSTN/ISDN and should look at moving in the near future.

If you do not move you will be looking a reduced service and paying more for the same service.
