• The UK's PSTN network will switch off in 2025 [telecom]

    From Bill Horne@21:1/5 to All on Sat May 21 15:13:42 2022
    What's happening?

    We're moving all our customers from the old analogue public switched
    telephone network (PSTN) to a fully digital network. We've already
    started. We plan to have moved everyone over before Openreach stop the
    PSTN (and ISDN) service in 2025. By then, every phone line in the UK
    will be digital, routing calls over IP (Internet Protocol) rather than
    the traditional PSTN.

    When you say 'everyone...'?

    Yes, we mean everyone. Business and home. And it's not just your phone
    services you need to think about. It's everything else that currently
    uses the old phone network, all your non-voice services connected to
    PSTN or ISDN lines. Things like alarms, EPOS machines, door entry
    systems, CCTV, and faxes.

    Sounds a bit drastic. Why are you doing it?

    PSTN has been the backbone of the UK's phone network for decades. But
    we've all seen the dramatic changes in technology over the past few
    years, especially recently. It's all around us: smartphones, apps, the
    cloud, Zoom, Internet of Things, and so on.

    What you probably don't notice so much is the infrastructure that
    makes everything work. The telephone lines strung across the streets,
    the web of copper cables buried beneath your feet, some of which have
    been down there since the 19th century.

    It's now time to leap forward from PSTN to embrace the boundless
    possibilities of digital.

    I learned what "Planned Obsolescence" means back in college. It took
    until this moment to realize that the planning included me.

    That is not an argument, the same lines will still be used for ADSL and
    VDSL.

    There is just one problem: There are disadvantages.

    VoIP is more complex and needs a modem and router at home that needs to
    be powered all the time. This is not a good solution for fire alarm
    systems, elevator phones etc.
