The Openreach FTTC cabs usually have monitoring on the equipment, batteries and I believe also when the doors are open.

As to how they respond to the metrics and alarms from their monitoring is another question.

The loss of power will raise an alert in the NOC and they will arrange a power trained tech to investigate the cause , which could batteries or associated hardware . This will usually be within 2 hours of the failure.

This is the problem I have at the moment in both Central London and Rural Oxfordshire. In London we have a choice of (i) FTTC (fails around 45mins after power goes, based on last local power cut), (ii) Virgin Media (fails immediately on power cut), (iii) G.Network FTTP- fibre goes to a cabinet with limited battery back-up. How long iit can stay up not known. (iv) 4G Mobile (nominal 2 hour battery back-up). I used to have an ADSL line to the local TE, which has maintained power, but that was switched by the ISP to FTTC a couple of years ago. In Oxfordshire there is (i) ADSL, which I keep, although data rate is low, as the exchange has maintained power and has been fine for the power cuts experienced so far. (ii) FTTC (same limit as London), (iii) FTTP from Gigaclear (same limit as London) (iv) 4G Mobile (nominal 2 hour back-up), (v) Wireless Broadband (no back-up). So no solution that will operate for longer than a couple of hours in an area power cut unless Openreach decide to put in FTTP, which given what has already been deployed is unlikely before copper is removed.

From experience they seem to be somewhat indifferent. I know of two FTTC cabs which have faulty batteries and no sign of fixes:

#1 A rural location has an immediate failure as a modem on a UPS looses sync as soon as the power fails. Given the location has no mobile coverage on any network having access to communications is rather important. First spotted during storm Arwen, there were subsequently four full day planned power outages for the network to be upgraded during spring/summer 2022 and a couple more long weather-related outages December 2022.

#2 Small city suburbs, the power is usually pretty reliable but there have been a few long brownouts / complete dopouts of several seconds over the last year. Again a modem on a UPS looses sync, it seems to take somewhere between one and two minutes to reestablish connectivity with the DSLAM rebooting, DSL training and PPPoE starting.

As others have said there doesn't seem to be any mechanism to report this.

Id suggest reporting it as a damage issue.

In the event of power cuts, will xDSL lines still provide signal to the router?

Assuming the property has a battery backup, and the router is powered up.
With POTS we knew the line was 'always on' for voice calls.

But will ADSL or FTTC connections work?

Forgive me here but as a domestic user even SME, why are you so reliant on the internet? Same goes for the black mirror devices that rely on 5 soon to be 6g ? My generation relied on neither and we thrived

Fairly soonish (OK end 2025) everyone will be reliant for internet to even make phone calls.

Internet connectivity really is the 4th utility of the modern age.

Interesting you making above statement while tapping on a electronic keyboard which back in the day would have been alien to most people but is very normal now. 😎

Different times, but I kind of agree, I see people that are on their phones all the time, certainly the younger generation, even in the pub yesterday, I used mine twice, just to find out some info about something we were talking about, so a smartphone is great for that.

If my broadband went down, I would do something else or read, sure if it was down for a day or so it would be annoying, because as I said above different times. People miss so much when they have their head stuck in their phones.

I appreciate that this thread is focused on domestic uses, but the same infrastructure supports business users, who have alarms and telemetry which currently are carried on internet, backed-up by GSM and special protocols over copper. The withdrawal of copper is a major concern in areas where Openreach FTTP is not available.
