Landline & Alarm Line Switch Off 2025
(ISDN / PSTN)

Digital Phone Solutions

What's happening?

The Public Switch Telephone Network (PSTN) will close in December 2025.

By then, every phone line in the UK will have moved to a fully digital network that uses Internet Protocol (IP) across a fibre-based service. This won’t just affect voice services, it may also mean you need to upgrade your broadband.

 

Any equipment that currently uses the PSTN will stop working; alarms, EPOS machines, door entry systems, CCTV, faxes, and so on. The Integrated Services Digital Network (ISDN) will also stop working.

Why is this happening?

Our current network is old and difficult to maintain. As an essentially 20th century technology, the PSTN is increasingly out of kilter with the demands of 21st century communications.

Traditional phone usage is changing everywhere as people switch to mobile and internet communications. We all expect much more from modern phone services than the traditional technologies can deliver.

What does this mean for me?

At some point before 2025, you’ll need to move from PSTN to the latest IP technology.

To help make that possible, BT is busy rolling out the Full Fibre network (Fibre To The Premises or FTTP) in phases across the UK. BT will stop selling traditional phone lines in all exchange areas by September 2023.

  • What is Fibre Broadband
    It’s the next generation broadband technology that uses fibre optic cabling instead of copper. It enables much faster and more reliable connectivity for businesses. The three main types of business fibre broadband are fibre to the cabinet (FTTC), Fibre to the premises (FTTP) and a more dedicated solution called a leased line.
  • What is Full Fibre Broadband
    Full Fibre is fibre to the premises (FTTP). It’s a pure fibre connection from the exchange to your business. It offers higher broadband speeds to specific premises in areas that have been enabled for FTTP (speeds up to 900Mbps).
  • What are the differences between FTTC/ FTTP & Leased lines
    FTTC, or fibre to the cabinet, uses a combination of fibre optic and copper cables between your business premises and your local exchange. Fibre optic cable is installed to a green cabinet in the street, and from the cabinet to your business premises, standard copper cable is used to deliver the remainder of your broadband connection. FTTC offers faster and more reliable broadband than standard broadband, which only uses copper to connect your business premises to the exchange. FTTP, also known as Full Fibre, is fibre to the premises. It uses fibre optic cabling between your local exchange and your business premises. Because only fibre optic cabling is used, FTTP offers much faster and more reliable broadband than FTTC and is significantly better than broadband that uses copper alone. A leased line offers businesses a personal internet connection with dedicated bandwidth and significantly faster speeds than FTTP broadband (up to 10Gbps). It’s ideal for data hungry businesses and when internet access is business critical.
  • What kind of fibre can I get?
    Based on your address we’ll either supply you with fibre that comes to your property via a cabinet and copper or full fibre. We’ll work out what you can get at the time you place your order and display the appropriate packages and speeds available to you.
  • How fast can my Fibre go?
    Based on what way we need to get the fibre service to your property you will have an option to choose the highest speed possible. If you are Full Fibre, you could potentially have up to 900Mbps.
  • I need a dedicated Fibre line. What are my options?
    If you don't want to share the network with anyone else, and need faster connectivity, then our leased line service providing dedicated internet access might be for you.
  • I only need Broadband. Do I need a phone line too?
    Depending on what's available at your address you may still need to have a traditional phone line. This could be due to compatibility with 3rd party products, but also that you are not yet in a full fibre area. If you are still in an area where your fibre is delivered from a fibre cabinet, it's only possible to supply this over a phone line.
