Used to be there were public utility regulations and FCC, I think regulations that required 8 hour minimum for POTS.

When that code was written, the issue would have been PBX’s, but it would apply to ATA’s as well. I used to tell people get a POTS line for that and the telco has you covered. If they don’t listen to me it’s not my fault. I wouldn’t provide the backup power for it because then it would fall on me to maintain the batteries to keep them compliant. They need to handle that themselves. I’m referring to the building code in my own city, and i don’t know if that’s their own rule or something adopted from ICC. It’s a sensible rule regardless, and property owners should be doing that even if it isnt a rule in their locality.

But unless they have a whole home generator, their Internet stops working if their Internet equipment (router, modem, ONT, radio, gateway, etc.) doesn’t have power. Have any of you found a UPS that fits this use case? Everybody wants to sell you an 800 VA battery backup with 30 minutes of runtime. It’s the old paradigm of powering your desktop computer long enough to save your work and shut it down. What we need is something that delivers 1/10 that much power for 10 times that long. Yes, I realize a big part of the problem is the inefficiency of DC/AC conversion especially at low power levels. And there have occasionally been DC battery backups for network equipment, usually for a specific model of CPE. But we are often faced with a radio that wants 24-30 or 48-56 VDC, and a WiFi router that wants 5 or 12 VDC. If this was for our own use, I could build something with some DIN rail electronics and a battery, but it wouldn’t be UL approved or appropriate for a customer to use in their home. People these days get alerted on their phone because their doorbell camera is offline, and they call their ISP rather than check for power outages. If they had a UPS for their Internet equipment, they would get an alert that their POWER was off. Ideally it would run for 8 hours which seems to be a typical restoral time for power companies. But I guess even with a couple hours they would at least know why their security camera is offline. And if they are home they continue doing stuff online for awhile and start planning where to go for public WiFi if the power outage lasts longer than their battery runtime. -- AF mailing list [email protected] <mailto:[email protected]> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
