I was unreasonably jealous of my friends with their keypad phones, but my family kept the old rotary until eventually they gave it back (remember, they were rentals) and got a cordless Cyberbird posted:phones used to work during power outages? my millenial rear end learned something today. yes, they were powered through the line. the little power they needed anyway, like for ringing the bell on an incoming call they even survived the Italian blackout of 2003, when someone (well, a tree) literally tripped on a wire and accidentally the whole country e: I'm not old, I swear.

Well this is tangentially related to POTS stuff Back in the day when I was kid there were still these things called payphones, and your local telco started rolling out these really fancy smartcard based payphones. And by smart cards we're talking about cards with something like 256 bits of storage, with some bits read-only and rest of them write-only. Basically card would have some 200 bits that all were initially zeroed, and when you wrote 1 there, you couldn't zero them again. Every time charging pulse came through the line, it would set up one more bit to 1. Payphone would check how many zeroes were left in memory and as long if it was > 0, you could keep on calling. And probably because this write-only memory was implemented with fuses of some kind, these cards required multiple voltages, one +5V for reading the card and then higher voltage for programming the card. so guess what happened if you put some non-conducting tape over C6 pin that provides programming voltage to the card?

australian payphones used to be coin-operated but then at some point they introduced prepaid phone cards and over time most payphones stopped taking coins. then some time later they phased out the old magstripe phone cards for newer smartcard ones (i'd heard stories of people hacking the magnetic ones to get unlimited credit lol) but by then mobile phones were becoming common so they were like "oh gently caress" and just brought back coin op again. then payphones started disappearing but not vanishing completely (you still see them at train stations, shopping districts etc) and as ~coxy said now they're also setting them up as wifi hotspots which is a p. good idea tbh (though if lte plans ever get better in this monopolistic shithole even that would become redundant i guess) also the hotspots suck because they only let people with a telstra home internet plan use them, there's no other way to pay to use them without signing up for a bunch of other crap. though even that is potentially starting to look appealing since after the best isp was acquired by the second best a few years ago they've now both just been bought out by literally the shittest

Stubb Dogg posted:Well this is tangentially related to POTS stuff then there were bt phonecards, which were even more low-tech. they looked like this:  those squares with numbers were the actual store of value on the card. a "laser" (actually just an ir diode with a lens) would scan across it, the boxes were ir-translucent but the rest of the card wasn't. when a unit was used the diode would turn up to 11 and melt the lacquer and make the plastic ir-opaque, removing the value from that part of the card and leaving you with a visible sign (like a scratch) of how much credit was used on the card. it was surprisingly secure (although it tended to false-positive, any kind of damage on the face of the card would render it useless) until an someone discovered a particular brand of nail varnish, if applied at just the right thickness, kept the ir-translucent properties and was made opaque by the erase function, but could then be removed with nail polish remover and reapplied, giving you all your credit back also there was another scam where you could use a hairdryer to melt the laqcuer on the front of the card to hide the scratches made by the erase function and sell on the "new" phonecard you "found" for a decent discount off the face value. every school kid in london knew that one, and probably every tourist in london in the eighties at some point bought a phonecard off some fresh-faced cherub after finding all the coin payphones were mysteriously out of order, perfectly capturing the entrepreneurial spirt of thatcher's britain

back in the mid 80s when the feds broke up ma-bell there was initially no way for a third-party long distance company, especially the small ones, to interface directly with your phone service. instead you got a card with an access code and what you did was dial a local access number, punch in the code and then dial your target number. since this code had to be manually entered every time it was usually only a 6 or 7 digit number. even after the breakup, long-distance calling was still ridiculously expensive (calling coast-to-coast in the us could cost up to $1 a minute). anyone who was into BBS-ing at the time probably has a story involving a $500 phone bill. to get around this you would run a program that would generate random calling card numbers, try using the generated number to call a service like compuserve and if it got a carrier it would save that number. since the access codes were only 6 or 7 digits and these companies often had thousands of subscribers, it usually didn't take long to find a couple of working numbers. then you could call long-distance BBSes for a month without your parents murdering you or having your phone service shut off due to inability to pay. the small long-distance companies that were often the targets of these number generators couldn't really do anything about it since they had no access to phone company records and couldn't trace the origins of these calls. some people started getting busted around 1990, but the problem didn't really go away until they started auto-connecting long-distance calls directly to the long-distance companies.

that reminds me of the early stages of  telco deregulation when i was a kid. for a while the monopoly became an duopoly. to make a cheaper long distance call with optus (still using telstra's network at the time) all you had to do was prefix the number with 1. that was weird

to be honest I've never been through a power outage long enough that it would drain the comcast gateway's battery for phone service, even before my parents had switched from regular landline to comcast landline.
