Copper landline "old and outdated".

Whilst you may not be familiar with the context of the term ‘landline’ for telephony equipment, it is a term that has literally been used for decades.

There’s frankly little point of continuing the conversation. You’ve been provided with an explanation. You either accept the change, or you don’t. It’s called progress whether you choose to accept it or not.

"You misunderstood what the communication said , it’s the PSTN (telephone) equipment within the telephone exchange that is old and outdated and being retired"

Actually it's BT that is causing this confusion.
In its communications (both email and mailings) telling people that they're going to be migrated to DV they say that is because they need to retire the "old and updated copper cables".
They don't say that all that is being retired (for the significant number of its customers still on FTTC) is the PTSN equipment at the exchange.
That is why so many people assume that migration to DV will also be accompanied by getting a full fibre service

Thank you Chrisjp, that's a helpful and polite explanation, unlike the previous post.

I think the expression dates from the first world war when communication in the trenches was based on a telephone  “land” based “line” as radio was comparatively new and uncommon.

But you are right, it should refer to a cable not a communications system.

My personal favourite is ethernet.  Everybody today seems to think that is a cable type.  Nope.  It’s the name of a transmission format and ethernet can be passed over may cable types, including twisted pair, coaxial and fibre optic.  So what exactly is an “ethernet cable”?

Misuse of terminology is rife in home IT these days, so I’m not surprised confusion arises.

Nowhere in the communication is the word 'copper' mentioned.

Unfortunately the term 'landline' means many things to many people. Equally unfortunately, correct terminology also baffles many people, ergo you can't win.

Equally, this forum is littered with posts in threads where folks just refuse to accept what is being said and they then turn the whole thing into an argument. You can’t win.

The bottom line is your landline phone service will be changing to a VOIP system which BT call Digital Voice.

Your only choice with BT in regards to that is to accept that or do without a BT landline phone service. 

Assuming you do not want to just use a mobile phone service you can of course arrange your own landline phone service through an other provider but I doubt you will find one that will be using anything other than a VOIP service.
