Everyone will need to buy either new phones or else a converter (essentially
analogue/digital interface) to allow existing analogue phone to work.

Either way, power will be needed for these phones or converters, which means
that a landline phone cannot be relied on during power cuts. When we were
having up-down-up-down power cuts the other night, I was able to use an "old
fashioned" corded phone to phone the power distribution people.

The converter or new phone could include a rechargeable battery, perhaps of the same size as common non-rechargeables, acting as part of a mini-UPS. As an option, the phone could then optionally ring you, there or elsewhere, to tell you that the power had gone off/on ...

However, a switch-off of the analogue phone signal does not _require_ a switch-off of the DC power which is applied to the distant end of your telephone feed.

No, although as the UK moves gradually towards FTTP rather than ADSL or
FTTC, the ability to take DC power from the exchange or cabinet will be
removed.

Good idea to have a rechargeable battery as a short-term UPS - why didn't I
think of that?

BT used to supply a BBU (Battery back up unit) with their fibre network terminals but (a) I don't know how widely the analogue phone port (FVA) was used (b) this has been removed from the universal service obligation and now they don't.

Wont fibre to the cabinet at least become normal once digital has fully
taken over, the few people who dont
have broadband or transferred to one of the plans that use fibre for part
of the route from the exchange
will fairly small by then and be connected in that manner wether they like

With no copper connection it wont be possible to power phones by DC from

It's not clear whether you think that today, FTTC customers have no

But those green cabinets have a power supply (and a non-smart meter !!)
so they could still supply DC from there (in theory).

Perhaps we're powered by the cab, then, We've got FTTC and the old
analogue phone works just fine when there's no volts to the house.

No, the point is that there *is* copper all the way back to the
exchange, so the line voltage and analogue calls are provided from there
just like the old days, it's only the broadband that is delivered from
the cabinet (it is possible to have line cards in the cabinets, but
openreach don't do that)

Not a lot. This is already happening in Australia with the
VDSL2 service. All it means for the average home phone
user is that the landline phone is plugged into the modem
/router instead of the phone line and is a voip service.

The most obvious difference for the average home phone
user is that there is no longer a phone service during a mains
failure because the modem/router is no longer powered.
But that is no big deal because the mobile phone service
normally keeps working during a mains failure.

Some of the other broadband services like the FTTP service
has a backup battery in the modem/router which means
that the phone service continues during a mains failure
and with the VDSL2 service you are free to have your own
ups for the modem router if you want to go that route.

Thoughts?

I gave up on those, they just make my head hurt.

Whne the mains is present... I think most cabinets have batteries to
bridge short mains interuptions without the kit rebooting. They may
have enough capacity to keep the cabinet alive for 3 hours or so
which is (IIRC) about the time that the batteries in a FTTP box last.

One near me has a smart meter with dedicated analogue telephone line
connected to the meter. It also has a large SLA 48V backup battery
made of four 12V batteries I think.

Once everyone has been moved to VoIP there will be no need for
many exchanges so they will probably be sold. Around here, for example,
the fibre from each green cabinet goes to a different exchange to the
copper. So once the copper is no longer needed, one of those exchanges
is also redundant.

With the first two phones I had installed, all I had to do to use them
was to pick up the receiver.

These days I now have VOIP which is much cheaper but to make it work I
have to know how to install and configure my router and home network
wiring. I also have to understand how to configure the VOIP equipment
itself. I need a PC or maybe a mobile phone to do all this.

Were I to use BT or Vonage VOIP equipment which might be configured for
me, I would probably have to pay much more for phone calls.

My landline wired phones will work in a power cut. The power supply
company likes to send me text messages about power cuts. Thankfully my
mobile phone is able to receive these so long as the battery is charged.

Well a little while back it was supposed to be next year, If it means
everyone gets an internet connection, I'm all for it. And all that crappy
overhead naff cable carrying broadband can go away and the horrible
interference it causes will vanish. However knowing such things as I do, I
doubt its that simple.
One big issue for society, and has already been experienced in Sweden, is
can we keep the infrastructure of Voip up during disasters. In the case of
the twisted pair so to speak, BT had batteries at the exchanges, but since
this means there will be no exchanges and the system is no doubt powered in
the streets from normal mains, will it all go down leaving us all cut off?

I think Germany are ahead of us, so we shall see.

The plan though is to sell off the exchanges and remove the cabling for
recycling. The fact is that the router will still need power as will the
street infrastructure, be it coaxial cable or fibre.

Virgin have decided not to fix new wiring into faulty phone installations,
where possible just move the subscriber to a new unused circuit. I imagine
they will be going down the same route. One problem I have had with land
lines using voip is that a tone dialling memory device held against the
microphone is nowhere near as reliable as on a directly connected phone.

didn't I think of that?

I had one for a few years. When I moved in, the phone line had been
re-allocated to another house and there were no spare cores in the
multicore to the telegraph pole. I therefore ended up with a DACs unit
on the wall to multiplex my phone onto a line shared with another house.
It had its own battery to power it, that recharged from the phone line
when it was not in use. It also had a mains charger, in case unusually
heavy usage drained the battery faster than the line could recharge it.

Of course the problem with rechargeables is that you only notice that
they have died when you need them!

It does with both FTTP and FTTC because with those there
is no way to provide that power anymore. While the wires
are still there with FTTC, the micronode is in fact powered
by the consumer. And even with FTTN, the node doesnt
have the capacity to supply power to the consumer anymore.

In theory at least ours will all be gone 18 months after
the broadband service has become available to them.
They have to change to have the landline service over
the broadband service or decide they are happy with
a mobile service alone. I say in theory because in
practice there are still a few dinosaur services that
still need the copper back to the exchange like
some of the older traffic light systems etc, but
they are still pulling the plug on the old POTS
services for households. So no copper between
the cabinet and the exchange anymore.

and be connected in that manner wether they like
it or not. With no copper connection it wont be
possible to power phones by DC from the exchange.

Yep. And our RIMs and CMUXes have had only
fibre back to the exchange for decades now.
And once all the POTS and adsl service they
provide have been cut over to the FTTP or FTTC
they will all be gone too.

fashioned" corded phone to phone the power distribution people.

The converter or new phone could include a rechargeable battery, perhaps
of the same size as common non-rechargeables, acting as part of a
mini-UPS. As an option, the phone could then optionally ring you, there
or elsewhere, to tell you that the power had gone off/on ...

However, a switch-off of the analogue phone signal does not _require_ a
switch-off of the DC power which is applied to the distant end of your
telephone feed.

Don’t get anything like that here.

LOL.

At glacial speed.

Unless the power cut drops the local cell down of course.

Doesn’t here.

Thoughts?

With the first two phones I had installed, all I had to do to use them
was to pick up the receiver.

These days I now have VOIP which is much cheaper but to make it work I
have to know how to install and configure my router and home network
wiring. I also have to understand how to configure the VOIP equipment
itself. I need a PC or maybe a mobile phone to do all this.

Were I to use BT or Vonage VOIP equipment which might be configured for
me, I would probably have to pay much more for phone calls.

My landline wired phones will work in a power cut. The power supply
company likes to send me text messages about power cuts. Thankfully my
mobile phone is able to receive these so long as the battery is charged.

Mobiles yes but not proper VOIP calls. Unless you are trying to use
VOIP over an iffy mobile data link rather than a stable
ADSL/VDSL/FTTP connection but even then it's just drop outsrather
than the mangled donald duck noises that mobiles produce.

Never ever get any mangled donald duck noises
with my mobile and I use it for all calls now.

Everyone will need to buy either new phones or else a converter
(essentially
analogue/digital interface) to allow existing analogue phone to work.

Either way, power will be needed for these phones or converters,
which means
that a landline phone cannot be relied on during power cuts. When we

No, although as the UK moves gradually towards FTTP rather than ADSL or
FTTC, the ability to take DC power from the exchange or cabinet will be
removed.

The FTTP "cable" typically installed, is actually a hybrid cable with a
main fibre section, but it also includes a thin copper pair bonded to it.

Good idea to have a rechargeable battery as a short-term UPS - why
didn't I think of that?

The PON termination kit, with the fibre modem, and PSU etc includes a
battery backup as standard.

Of course not, senile auto-contradictor! If it did, you couldn't
