What You Need to Know

Openreach has now begun to issue ‘Stop/Sell’ notices on legacy copper products where the local exchange has reached 75% fibre coverage (broadband). These notices provide an advanced 12-month warning that legacy services will no longer be available from those affected exchanges where alternative fibre solutions can now be provided at such geographical locations.

The result of these changes is that the WLR/PSTN services which have supported TNS’ Broadband communications solutions to ATM or POS devices will no longer be available to support new customers’ requirements post Stop/Sell notices taking effect at a serving exchange. Customers will need to migrate to a fibre based product which will be available based on location and service type by the underlying service provider.

By December 2025, all customer premises operated by POS vendors, ATM operators and deployers will need to have been migrated or in the process of migration to fibre based services which no longer rely on the copper network between the affected customer premises and the Openreach serving exchange as the associated WLR services will have been withdrawn. This means that access or other previously copper-based services will need to be provided using a fibre based service, and the operation of the affected POS and ATM devices at such customer premises. will need to be supported over an alternate IP/broadband solution.

Understand More About What Openreach Stop/Sell Means?

The implementation of a Stop/Sell notification on a local exchange does not mean the existing WLR/PSTN services at existing customer premises will be ceased, it means that no new WLR/PSTN based products will be available for new orders at such premises from that Stop/Sell date on an exchange basis.

Openreach will support WLR/PSTN connectivity up to the end of December 2025. However, if a fault occurs on an existing PSTN/WLR service, it may not be repaired if a replacement fibre or IP service is available at the affected customer premises. The longevity of WLR is expected to cover a three-year period from the Stop/Sell activation date on a given exchange.

Therefore, it is essential that customer premises (and affected devices) using PSTN/WLR service components are migrated to an IP-based solution before that date.

Between now and the end of 2025 communication providers utilising the Openreach access products will ‘encourage’ as many customers as possible to migrate away from WLR access services. In locations where a fibre alternative to WLR/PSTN is available, service providers will seek to migrate customers to IP-based products (using fibre) which could impact any renewal of any existing service contracts. The replacement fibre or IP services for WLR/PSTN access are based on SOGEA-FTTC (Single Order Generic Ethernet-Fibre to the Cabinet) or GEA-FTTP (Generic Ethernet Access-Fibre to the Premises).

Considerations When Moving from WLR/PSTN to IP

Where any new premises have access to a GEA-FTTP service, this will be the only service that can be ordered at such premises.

  • If premises have GEA-FTTP service available to order, then such premises are immediately impacted and the only available option is a GEA-FTTP solution at those premises.
  • If premises do not have GEA-FTTP service available, the following alternative services will be available based on the following priority:
    • SOTAP (where no fibre is available)
    • MPF & WLR (only available until September 2023)
  • Consideration needs to be given to any router or other equipment (which is supplied as part of the existing service) and whether it is capable of supporting fibre-based services. If the equipment is not be able to be reconfigured, the premises will require replacement equipment in order to support the new service.

What Do You Need to Do Now?

  • Review your installed base to identify those premises that are of strategic importance to your business.
  • Prioritize those locations and the associated PSTN/WLR services that will be withdrawn as Stop/Sell notices are issued.
  • Consider other services that support your business which may also be impacted by the Stop/Sell notices.

  • Any service supported via a WLR/PSTN access services
  • Alarm-based services
  • CCTV-based services
  • Public Internet Based Access
  • PSTN telephone service
  • Are other services, such as POS Terminals, attached to their lines?
  • Contracted services with other suppliers, in particular do you have contracts for affected PSTN/WLR services with multiple providers?
  • Will the affected premises need to keep their current PSTN number(s)?

How is TNS Supporting the Migration to IP?

TNS is committed to assure the seamless migration in the UK to IP-based broadband services and is attending WLR withdrawal related UK forums. These include Openreach’s Industry Working Groups on how they are implementing the changes and Ofcom’s “All IP Steering Group” which covers any associated regulations, standards and communications.

TNS provides insight regarding POS and ATM sector (and the associated communications products which that sector deploys) to both the Ofcom Steering Group and the UK standards group, NICC. This means that TNS has highlighted to Ofcom and NICC that the services which POS and ATM deployers are currently using are legacy products so that the UK communications industry are advised of the impact of the PSTN/WLR changes to the POS/ATM sector.

  • TNS will provide updates during reviews with its customers as to the impact of Stop/Sell on its customer base. This will primarily relate to sharing of information regarding Openreach exchanges closure, impact to new business and options for customers to be apprised of regarding their business.
  • TNS will notify customers through its reviews when Openreach publish their Stop/Sell notices impacting local exchanges. These notices provide a year’s advance warning of when copper products will no longer be available to implement at existing/new premises to facilitate the connection into individual exchanges.
  • TNS will work with the UK telecoms industry to gain information on services affected by exchange Stop/Sell notices.
  • TNS has already tested the replacement products of SOGEA-FTTC and FTTP against its network and delivery process.
  • TNS will produce advice regarding the risks relating to the current WLR services and where we see trends developing as the Stop/Sell program is undertaken. This may include end of sale, end of support and sunset notices from Openreach and/or TNS.
  • TNS will continue to support customers with information so they can advise their business of the affecting changes.
  • At this time, TNS is unable to advise of a like-for-like migration path given that Openreach have not communicated when existing ADSL broadband services will be withdrawn. However, Openreach have stated that WLR will be fully withdrawn from sale in September 2023.
  • TNS will work with customers toward finding the appropriate alternative connectivity solution from TNS’ robust catalogue of services, including:
    • Broadband (FTTP, SOGFAST, SOGEA, SOTAP) as the primary connection
    • Broadband (FTTP, SOGFAST, SOGEA, SOTAP) as the primary connection with wireless backup
    • Wireless as the primary connection
    • Wireless as the primary connection with a wireless backup
