In that case if you have a  mobile phone...just use that and save a lot of hassle?

PAYG with no data

Might be time to review your mobile options ,   

if that important to stay connected Lebara  are doing 15GB 6months at £1.34pm 
lower data even cheaper. 3GB 6month at 24p/m

This would do the job - https://www.amazon.co.uk/Eaton-3S-Mini-black-white/dp/B092TG9M7C/ref=sr_1_8?keywords=router+ups+power+supply+uk&qid=1665919899&qu=eyJxc2MiOiIyLjkyIiwicXNhIjoiMS4wMCIsInFzcCI6IjAuMDAifQ==&sr=8-8

Not sure how long it would power a router for, it says 36W but not sure how that relates to run time.

Think you would need a bigger UPS to run router for any length of time. I get frequent power cuts and have a very old Eaton Ellipse 1000VA UPS, runs router and modem for about 4 hours during a power cut. Actually have 2 UPS, so when one runs out, can use the other, and/or use to charge laptop/phone if a very lengthy power cut.

Ok so mobile idea to use or as a hot spot is a non starter.

If you are competent with electricity even as a DIYer to make safely: ( and that might be doubted given your questions)

12v battery fed through a suitably sized fuse should work for a while till discharged. Time will depend upon current drawn by the router and the battery useable capacity.

Care needs to be taken with battery connections to ensure correct polarity supplied to the router PLUS to ensure the battery is not short circuited as that can result in a massive current flow burns or fire and destruction of the connection  cable or other short circuit method. The assumption here is you use a sealed car type battery, a gel type battery or similar (for cost and sufficient capacity reasons). From fully charged a 40Ah battery would give you 20 hours of use at 1amp router current and cost maybe £60 upwards plus enclosure connectors etc.

Use cable & connectors etc that are suitable for the current required by the router and no heavier and fuse physically close to the battery at the same level and use a switch as well.

If you are not competent and can not buy a backup supply or a smart mobile with data then for safety reasons give it a miss and enjoy peace and quiet and a natural moment or more.

Thanks for your very succinct and comprehensive answer, much appreciated. I am competent elec/DIY The main point of my question was to get opinions on whether the cabinet/exchange would still be functioning.. However I had overlooked the need for a fuse, so thanks again.

All BT roadside cabinets have UPS that run for 4 hours
They are the checked 6 monthly
