PSTN - Public Switched Telephone Network

[cjenkz22]

i hear "By 2025, the existing analogue technology (the PSTN - Public Switched Telephone Network) which has supported phone and broadband services for decades will be switched off and replaced with newer digital technology."

Does Sky use/rent BT phones lines? 

i currently have broadband and talk , my internet is connected to a old phone socked with a ADSL filter , will i need to upgrade my package?

Thanks.

For people with adsl openreach are introducing sotap which allows copper to the exchange to use internet calls. If you are on vdsl superfast openreach already  have sogea so if you already have the sr203 broadband up the only difference will be your existing phone plugs into the back of your router

Sky uses the Openreach network, and Openreach Ltd is a division of BT Group.

All ISPs need to replace their legacy routers with models that support internet telephony: for Sky that's several million Q Hubs (plus all earlier units) and they will be doing so over the next twenty months.  Some very antique broadband subscriptions may also have to be updated, but the underlying FTTC, G.fast and FTTP broadband technologies are all already capable of carrying the necessary data traffic.

Note that the current target for PSTN switch off is December 2025 rather than 'by 2025': that appears to be an unfortunate error on a BT web page.

When I switched  to full fibre broadband  in January of this year, the open reach engineer  told me  that all the old phone will be switched off  by December  2025, and switched to fibre  optic cables

As off september last all new broadband vdsl customers havd already been taken off the ptsn and moved to sogea. All fttp have already been using internet calls . The only thing is generally all settings for broadband shield and talk shield have to be started up again

Note that's not the same process.  Copper lines will be carrying digital data to some addresses for many years beyond PSTN switch off.

Thanks for your answers.

Since the previous posts, the deadline for PSTN switch-off has been revised to January 31st 2027 and the BT web page linked above has been amended accordingly.
