Withdrawal of WLR

Don’t panic. Be properly prepared

The Public Switched Telephone Network (PSTN) will reach the end of its life in
December 2025. After this date, any services supported on Wholesale Line Rental (WLR), including Single Analogue Lines, Multi-Lines, ISDN2 and ISDN30, will need to move to alternatives.
The big switch off will also impact LLU SMPF, SLU MPF, Narrowband Line Share and Classic Products.

Openreach and BT will withdraw the Wholesale Line Rental (WLR) service by 2025. It sounds an age, but it isn’t.

The PSTN is closing 2025 and WLR is being withdrawn. Are you ready?

BT & Openreach announced some time ago the intention to switch off the ISDN services from the Public Switched Telephone Network (PSTN) by 2025. They have also announced that they intend to switch off the whole PSTN service by 2025, with no new supply after 2023.

Although they’ve been the most reliable solutions to date, PSTN and ISDN are rapidly becoming out of date technology, and expensive to operate and maintain. Openreach plans to invest instead in fibre infrastructure rather than further invest in a new version of the PSTN (which is essentially Victorian technology)

This means that any individual or organisation still using these traditional voice services will need to have moved to newer SIP and IP voice solutions by then or, simply put, they won’t be able to use their phones.

Public Switched Telephone Network (PSTN) closure and what it means? 

Openreach is modernising the way they deliver telephone services to the UK. The PSTN is ageing and will reach the end of its life in December 2025. New digital technologies are talking its place, which means over 16 milion lines and channels will need to move to alternative products before the network is switched off. 

Moving to new technologies will open the door to exicting opportunities to develop more reliable and future proof prodcuts and services for decades to come.

Solutions? What are the alternatives?
