Confusion about land line and Digital Voice

[oldles]

Also , no expert in any field, but have measured about 50volts +-  on a 'copper' ( not always ) landline , so the change to VOIP , I presume will result in the GPO 😁 cutting said voltage , ( big cost savings I guess ) The network will still use the pair( if your lucky ) of wires to reach my house for the time being, till they move to 5G or fiber. so powering the hub may be all is needed to keep the phone socket live. Am i wrong ?

@VeteranISPUser  I’ll do my best and give a reference, but this forum isn’t the easiest to navigate. Perhaps you could give me some advice on how to search comments to track down the one you are asking me to reference?

The term ‘landline’ has ( in my opinion foolishly ) been used by providers ( not just BT ) as a proxy for all telephony , similarly, BT’s proprietary IP phone system ‘Digital Voice’ seems to be used by others as a generic term for any and all providers IP telephony systems , so regrettably it’s now a confusing term landline isn’t just PSTN telephony over a copper pair .
A consumer with DV on FTTP ( for example ) has a ‘landline’ phone service, as does someone on DV but via FTTC , where at least there is still a copper pair involved….so pointing out that your ‘landline’ works during local power outages just means you don’t have DV ( or you do but have BBU/UPS )

There is no argument , a DV landline will not work in a power cut without mitigation , a PSTN landline will .

If , as you state , a forum member ( of standing ) stated ‘landlines’ without qualifying what type of landline service,  don’t work in a power cut , seems pretty unlikely , hence the request to provide a citation for it .

TBH , it’s something of a distraction from the original post anyway

Until there's a switch to full fibre then yes you only need to power the SmartHub2 to maintain a landline phone.

After full fibre the ONT will also need to be powered as well.

Obviously in both situations only handsets which are linked solely by DECT will work so no base stations will work unless also with battery backup. I guess a corded phone connected to the hub would also work.

It's amazing how these threads can wander of the topic a bit.

There is a Motorola phone which BT/EE market and this goes hand in hand with DV.  It's manufactured by Motorola and has an internal battery which should provide up to 8 hours service during a power cut and has a fallback service provided by an EE P&G SIM.  Although I'm not yet on DV myself I thought I'd get one before there's a rush on - that and the fact that I'm a gadget freak 😀.  The phone is as follows:-  BT FW500 Hybrid Back Up Phone and is available from the EE Phone shop for just under the £80 mark.  Food for thought maybe

@iniltous thanks for the response. The forum is to try to get accurate advice / opinions concerning landline and digital voice, hence my comment as i think it’s important to avoid confusing forum members who aren’t technologically savvy in all things concerning telecommunication. For that reason may i suggest that it’s not so much a distraction as a  side shoot but still a valid point to make since as you are at pains to point out the two terms seem to have been conflated?

@ChrisGee  The only person confusing people is you with your spurious unsubstantiated posts.

Landline has become a generic term for any form of fixed location telephony and encompasses legacy analogue, BT Digital Voice and third party VoIP systems.

Nowhere on this forum will you find that I have stated that a conventional hard wired  ANALOGUE landline will not work in a power cut. Why on earth would I comment on a system that has been in use for over a hundred years and is well understood. 

[ChrisGee]

It may be useful if you reproduce your comment which is the one i appear to have misread? That would be useful and give me an opportunity to correct my ‘spurious unsubstantiated’ post? 

[licquorice]

You're the one making the assertion, you must know as to which post you are referring. I have absolutely no idea which of the countless posts I have made you are referring to that you have misread.

To be fair to all and sundry, the 'landline' is not a telephone service. Twice now I have phone up BT to say that my landline has a problem and they start having a go saying that I told them my telephone wasn't working — they should know the difference, at least.

The 'landline' is the line that goes over/under land. It is as simple as that. So whether copper based ADSL, FTTC or Fibre to the Property (FTTP) where no copper is involved, they are still Land Lines.

The telephony service you receive is EITHER the old PSTN (Public Switched Telephone Network) OR VoIP (Voice over Internet Protocol) — either way, these are still LANDLINE services as they are provided exclusively over the line that goes over/under the land.

Simples.

This is opposed to telephony that goes over the air (OTA) such as VoIP over 4G (not provided by BT Digital Voice) or cellular services by mobile phone operators.

In this instance, LANDLINE is a correct term for Digital Voice or traditional phone services.

So 'if' someone said that the landline (in context of talking about Digital Voice) won't work in a power cut, then though not word for word exact perhaps, still conveys in context that the Digital Voice Telephone Service running over your LandLine will not work in a power cut.

You know this already. You have stated that you do. So you are trying to pick at people a bit really.
