Quote from: Alex G. Bell on June 27, 2017, 03:48:35 PMThe one strength that they do have is that they work without local power. AFAIK all VoIP solutions require the end user to provide power.
Quote from: unbeldi on June 27, 2017, 03:56:05 PMCertainly. But they become useless too with the vast majority of telephone sets sold today that operate with a wall wart (and have no batteries), and go dead just the same as an IP phone or ATA. Many cable Internet access providers supply cable modems or VoIP adapter with a battery backup. I got one in recent years that provided for 6 or 8 hours of backup power.

This is without considering rare events on the scale of Hurricane Sandy. I know people who were without power for weeks as a result of that. Living without heat, hot water or use of a stove you could still need to call for a medic or police.
Quote from: unbeldi on June 27, 2017, 04:03:32 PMThe optical network termination equipment installed in multi-dwelling structures, such as by VZ in apartment building in cities, usually have local batteries installed to keep them operating for some time.
Quote from: Alex G. Bell on June 27, 2017, 04:18:48 PMApparently not. The copper retirement notice I saw was sent to someone in a 64 unit 13 story urban building. If the ONT is going to be in the basement the customer would not need to provide access to a Vz installer nor keep a spare "D" cell handy.
Quote from: unbeldi on June 27, 2017, 04:17:05 PMWell, it is somewhat of a hypothetical benefit. Makes you feel good, or at least better. The people you most likely will call have dead iPhones by then.
Quote from: unbeldi on June 27, 2017, 04:17:05 PMThe meaningful activity would be to advocate for reliable power systems. Does it not seem inconceivable that mankind can send humans to Moon, and have robots operate on Mars for years and years, while being incapable of maintaining stable power in our cities ? Where is a sense of priority in that ?
Quote from: unbeldi on June 27, 2017, 04:27:51 PMCorrect, the ONT units in the basement are not individual units for each apartment, but serve multiple customers each. They should have some backup too. I think, but I am not sure, some can also be powered via the fiber optic cable. There are even optical power feeds where the termination device is powered by a high-power optical feed that is converted to electricity at the terminating end.
Quote from: unbeldi on June 27, 2017, 04:34:32 PMI think I misread your statement.I guess one has to examine what is installed in each situation. The replacement system is adapted to the existing wiring in the building. It may require installing local VDSL links for each customer from the basement.
QuoteWell, all of the telephones I own now, and will ever own, will not require any power besides that supplied over the telephone line.
