I don't see how technically a doctor could do that.

With a smartphone, use a VOIP application that allows customization of outbound caller ID. For example, I have Skype on my iPhone, and I have it set up to send my Google Voice number as the caller ID. Most systems that allow this do require some kind of verification that the supplied number is "controlled" by the caller. I think when I set up Skype, it gave me a verification code online and then called the number and asked me to enter the code. So it doesn't allow random spoofing, but the scenario of transmitting an office number instead of the cellphone number is possible with VOIP.

The exception was a pair-gain provision such as the Bell Systems SLC 96, which was used in rural areas and in areas of rapid residential construction. I believe the terminating SLC 96 box had to have local power. Anyone know differently? I imagine SLC 96s are long gone for residential suburban areas but they likely still exist in some rural areas.

Oh yes, SLC's need power. >I imagine SLC 96s are long gone for residential suburban areas >but they likely still exist in some rural areas. I was just in Aptos/Watsonville CA region, and there are SLC-96's on every other corner. The giveway is the line of shiny T1 repeater cans feeding same. I'd be far happier if they were SLC-FO's as then I could get Hi-Cap from them. But that's not to say the SLC powers the T1 feeding it. I assume that if the T span was long enough, it would be powered from both ends.

And, in addition to any technical or political (e.g. they're calling from outside the U.S.) hurdles that may make catching them difficult, for years the content of this very forum had led me to believe that there is little or no budget and less motivation for agencies to put in the work required to track down the culprits. Maybe the fine will encourage some agency to invest the time, but somehow I don't see this having any more effect than, say, the CAN-SPAM act had on all the junk mail we receive...

Bedini is one among the panoply of "Perpetual Motion Machine" theories that have been well and truly busted, more than once. TANSTAAFL, you need to get the energy from somewhere. Now you could set up your "Free Power" demonstration right under an overhead high tension transmission line, or a building right next to a high powered broadcast transmission tower and "magically" get energy out of the aether by tapping the EMF fields with your system acting as a simple antenna, but that's pure deception. Several of Tesla's original inventions were like that - transmission of energy without wires or physical connection, or tapping an external source, not creating it out of nothing. (You can walk around under an AM Broadcast antenna holding a fluorescent light bulb that's glowing in the RF field, especially at a 50KW Clear Channel blowtorch like KFI. Or up on Mount Wilson where all the TV transmitters serving Los Angeles County are, they've historically run obscene power levels up in the multi-megawatt range on the Video and another MW on the Audio - even after the digital conversion they have stayed high to ensure their reach through a geographically large market. That energy isn't "Free", it's just* someone else *getting stuck with the power bill.) It would be relatively simple to put reliable permanent automatic-start emergency power at all Telco, CellCo and CATV remote sites, but it has to be mandated by the regulatory agencies. The added cost puts one carrier at a serious competitive disadvantage versus the others that won't have all the capital sunk and the ongoing maintenance expenses, so they aren't going to do it voluntarily. Even though they'll be the only carriers still working through the next major disaster, that's very hard to sell to customers looking at the bottom-line price. It would be simple to build an armored curb-side pedestal combining a small generator plant, a gas meter if Natural Gas is available (unlimited run time if the gas distribution system stays up), and an automatic transfer switch & excercise controller. And nearby you bury a small double-wall fuel tank (gasoline, diesel, propane, their choice) in a standard concrete vault for a local fuel source - pop the outer lid and crane out the tank for service or inspection, and the vault is tertiary containment. (Much harder for a wayward car to run it over when it's buried.) Right now, the companies all say they'll bring out portable generators in an emergency. But they don't have anywhere near enough units to go around stored locally, and using service trucks equipped with generators parked at the sites takes them off necessary repair duties. They won't be able to deploy portable generators quickly with most highways roads and bridges impassible after a major earthquake or blizzard, especially if the central cache is stored out of state. (I've heard that's Verizon's emergency plan.) Arranging air-freight will take time, and as the Berlin Airlift showed there is a hard limit as to how much can be transported in by air if that's your only open route - plus humanitarian aid always has first priority. The Fire Department USAR Team and their gear will bump your generators every time, and by the time they get on a plane a week later the roads are open again. And as someone already pointed out, they don't make chains stout enough to lock up an unattended portable generator in some areas - or they'll cut the generator chassis and leave the chain... Heck, some of the permanent pedestal mounted ones may get stolen unless the pedestals are alarmed and a LEO can respond to the alarm in time. --<< Bruce >>-- [Attachment of type text/html removed.]
