PSTN Network Switch Off In 2025

The first stage Openreach propose to facilitate the retirement of their public switched telephone network (PSTN) is to issue 'Stop Sell' dates for specific telephone exchanges. Once a 'Stop Sell' date has passed, communication providers (CP's) will be unable to order any copper based products if a fibre solution is available at the customer's premises. Accepted fibre solutions include FTTP and SOGEA/SOGFast.

Impacted product and services that will be unavailable beyond a 'Stop Sell' date include WLR3 analogue, ISDN 2, ISDN 30, LLU SMPF, SLU SMPF, Narrowband Line Share and Classic products.

Openreach have identified 581 specific 'FTTP Priority Exchanges' that will be the first to receive 'Stop Sell' notices, see below.

Openreach have not identified the Treharris Exchange as a 'FTTP Priority Exchange' and the 'Stop Sell' date will be September 2023.
