What other lines and calls services are impacted by the 2025 closure?

The Public Switch Telephone Network currently supports WLR, ISDN2 and ISDN30, Local Loop Unbundling Shared Metallic Path Facilities (LLUSMPF), Narrowband Line Share and Classic Products. These products are commonly mentioned by providers when discussing the PSTN Withdrawal but most providers fail to mention the connectivity products which are using these services like Asymmetrical Digital Subscriber Lines (ADSL) Broadband and Fibre To The Cabinet (FTTC) Broadband which will be impacted the WLR End of Life project. This is because the underlying line product is being withdrawn, therefore there is no underlying WLR telephone service to support the broadband.
