A plain POTS set is almost unfairly cheap to keep alive. On-hook, it is basically a supervised loop drawing almost nothing at the subscriber end; off- hook it is tens of milliamps from a central battery plant that was built, maintained, and regulated around that job. An ONT plus router is a different animal. Even if the ONT idles well below its adapter rating, it is still active electronics at every customer site. If the service needs voice, routing, WiFi, or an ATA alive during an outage, then the backup problem has moved from one hardened central office to a pile of little boxes in houses, closets, and garages. That is why the old system felt magic. It was not the copper. It was the engineering assumption that the network had to power the endpoint and keep doing so when the customer's mains failed. Fiber can be made reliable too, but only if the same requirement is written down and paid for instead of being waved away as an optional battery accessory. -- TheLastSysop <thelastsysop@dev.null> "I survived the great rm -rf / rehearsal and all I got was this .signature."

On hook, on an old phone I think it is a capacitor in series with a bell ringer coil; there should be a 48 DC nominal volts and no current. To ring, the exchange sends an AC voltage of around 60 volts. Being AC it passes the capacitor. On a modern POTs terminal, there are active electronics, so there may be a small current draw while on hook -- Cheers, Carlos. ES🇪🇸, EU🇪🇺;

But, overall, that's How It Works. Simple yet functional.

The original engineering assumption was the central plant had to power the end points. And that was made, at the time, not because anyone thought about "emergency services calls" (such a concept simply did not exist before there was a widespread telephone network installed). The original design parameter of "central office powers the end points" was made because the phone network was being installed during the same time frame that mains electricity was first being installed as well. There was no guarantee that homes being wired for phones would have mains power yet, therefore the need for the phones to be powered from the central plant. > Fiber can be made reliable too, but only if the same requirement is > written down and paid for instead of being waved away as an optional > battery accessory. Yep, it would add expense. And the companies would cry-baby enough that they would end up wanting to charge $500/month or more for what they now charge $65/month if they were forced to make it equally as reliable.

The wart's labels are what it is rated to output without lighting your house on fire. If you measure the actual draw of the connected devices, you'll often find it is much less than the wart's max 2..3 amps. Often substantially less. In any case, that is also fixable. Run the power conductors at a higher voltage (48v -- the POE voltage) or even whatever your mains voltage is (220 in Spain?). Then the current in the big cable is much reduced, even with every end point 'running' and drawing power. It can be done, but it is also very much a not likely to be done thing as well. Of course this would likely mean fewer "end points" on each arm from the local switch, as no matter how high one runs the voltage on the power pair, there is a limit of how many demarc's it can power at once. Alternately, each "fiber line" could include a pair of power conductors to power that one end-point (again likely running a higher voltage to cover for resistive losses in the long wires). But also, just an 'imagined possibility'. No regulator today would think of trying to impose any such requirement anyway.

No regulator today would >think of trying to impose any such requirement anyway. For a home setup the useful first step is to measure the real load, not size from the wall-wart label. A cheap plug-in wattmeter on the AC side, or an inline DC meter if the router/ONT uses a barrel connector, will usually show a much smaller steady draw than the adapter's maximum rating. If the goal is keeping voice or basic connectivity alive through short power cuts, a small DC UPS or a modest AC UPS sized from that measured load is a lot simpler than trying to make the access network provide line power. Then check whether the ONT, router and any ATA/DECT base all need backup; missing one box in that chain is the usual surprise. -- TheLastSysop <thelastsysop@dev.null> "I survived the great rm -rf / rehearsal and all I got was this .signature."

Yeah, there's not enough energy in two AAA cells to power a modern router for longer than very brief intervals, unless that same router is very minimal power draw itself.. > <https://www.amazon.es/-/en/APC-Back-UPS-Connect-CP12036LI-Controladores/dp/B0CJ5D89Z9> > > <https://www.amazon.es/-/en/Internal-Battery-Lightweight-Protects-Overloads/dp/B07DPTF9VW> > > <https://www.amazon.es/-/en/Salicru-658BB000009-SPS-net2/dp/B0DHL4XRBW/> > > <https://www.amazon.es/-/en/Shanqiu-Router-Surveillance-Camera-Output/dp/B0FF9QS7LK/> Interesting, I'd not encountered these style "UPS" boxes yet.

It would be a tree network of DC cables going out from a central node. Two thick cables going out, perhaps 48V DC, then branching at each home (and fuses). At least part of the network would be thick cables. Which means, some people would try to steal them. -- Cheers, Carlos. ES🇪🇸, EU🇪🇺;

Oh yes, I had an inspection of 'my' substation - 3 phase 11KV in, 240v
100A out to my property. I am the only person connected.
Thieves had attempted to force the doors in order to steal the whole
transformer.
Any crowbar thrown across the lines will cause the 11kV circuits to trip
and stay tripped.

The lead acid is the older variety and the D cell is the newer one. I had to buy the older kind on eBay as they are not really available anymore. Neither is sufficient, you can get 8-24 hours of standby power with these kinds, but that's woefully inadequate in an extended outage, and both are now a significant cost that consumers are now expected to bear.

Verizon's FIOS/fiber successors (at least on the Verizon -> Frontier -> Ziply path) no longer provide for any battery backup. The new ziply ONTs have nothing for any duration longer than maybe a second (likely at most a fraction of a second). A customer can add a UPS to power the ONT, but it's anyone's guess whether Ziply now maintains power to even any neighborhood concentration equipment or "central office" facilities. -- Robert Riches spamtrap42@jacob21819.net (Yes, that is one of my email addresses.)

One practical thing is to treat the ONT, router, and any switch you actually need as one small critical load and measure that load before buying the UPS. A lot of the little network boxes draw less than their wall warts imply, so a modest UPS can run them longer than expected if it is not also carrying a PC, monitor, printer, etc. I would also do a planned pull-the-plug test while nothing important depends on it. If the ONT and router stay up but the provider's upstream plant drops, then more battery on the customer side will not buy much. If it stays online, then the UPS runtime number is actually worth optimizing. -- TheLastSysop <thelastsysop@dev.null> "I survived the great rm -rf / rehearsal and all I got was this .signature."
