The clock is ticking on the UK’s Public Switched Telephone Network (PSTN) as preparations for its shutdown gain momentum for the closure in 2025. As of April 2021, 297 exchanges have now been issued with a Stop/Sell notice with notices of other tranches to be subsequently released. In this blog we look at what this means to you and what should you consider.
The most significant impact of the PSTN shutdown for most will be that any services supported on any Wholesale Line Rental (WLR) product will need to migrate to new fibre products. The withdrawal of the PSTN will also impact single analogue lines, multi-lines, ISDN2 and ISDN30, local loop unbundling SMPF (sub loop unbundling metallic path facility), narrowband line share and classic products.
Broadband customers that have ADSL supported by single analogue lines will need to move to a new product such as SOGEA (Single Order Generic Ethernet Access) which is a fibre-to-the-cabinet or a fibre-to-the-premise (FTTP) product.
For merchants using TNS Dial for transmission of their payment transactions to their acquirer(s), there are two potential options to connect via IP to their associated terminal(s):
Typically, the only option is to connect the terminal to the router via the Analogue Telephone Adapter (ATA). This allows a local analogue connection to the router. Then all transactions will still be sent over the IP network from the router (via the carrier’s network) onto the merchant’s acquirer. This solution is not an optimum solution as the merchant could possibly see a degradation of service which will have an adverse effect on sending transactions to the acquirer for authorisation.
Customers using TNSLink for payment transactions and ATM communications should explore the following:
Following these steps should allow you to prepare for and approach the switch off strategically so that you can make decisions at the most beneficial time. Don’t let the 2025 deadline lull you into a false sense of security, the change is happening now and it’s moving promptly on schedule. Every new Stop/Sell notice gives an advance 12-month warning that WLR services will no longer be available from that exchange after that date. This year more than 170 exchanges will pass their Stop/Sell dates.
