Does that mean a LEC is a party to crank calls? A customer using a tariffed service (which the LEC is required by law to provide) in a way that the tariff either proscribes or does not cover can hardly be blamed on a Common Carrier.

Typical parking lights are rated 8-15 Watts, hence take an Ampere or so, plus or minus 30%, and a set of four will drain about 4 Amps. Over 6 hours, that'd be roughly 25 AH, which is "nothing" to a 300 AH-rated battery. > ... (I believe the headlights consume much more power). Right: a headlamp's low beam filament will consume about 7 A (or at least the one I have fed by a metered automotive battery charger, to illuminate my back yard at night, does); a high beam filament, more (and if your high beam filament is on in parallel with your low beam, you must add the two current draws together, effectively doubling it). A couple of those, *along with* the parking lights, dash lights, and whatever else always comes on when headlights come on, will drain some roughly 20 A *or more* -- over 8 hours, that'd make 160 AH or more, or enough to put a perceptible dent in a 300 AH-rated battery. > ...

For example, so far as I know, most calling features are (were in the case of California) offered under LEC-initiated tariffs. I don't know which type of tariff the feature group trunk for PBXes is; regulator initiated or LEC initiated. I remember in my fighting days how Pacific Bell loved to hide behind tariffs of their creation, by stating, "Oh we must do what that tariff says because that is the law."

Opinions? > Amongst my clients and acquaintances who have contacts in other countries, Skype is very popular. Not just individuals, but small organizations that have offices in other countries. And most of these are not people I'd call "early adopters", some of them have needed a little help getting it set up, even though it's very easy to set up. Not so much as a PC-to-telephone link, but as a PC-to-PC videophone link. Because if both ends have Skype, it doesn't cost anything. Which of course does leave the question of the business model. I'm not sure that any of the people that I know pay Skype for calls to non-Skype telephones. Skype Access is an interesting business idea. It is a micropayment plan that uses your Skype account to pay for access to wifi networks. Apparently there's software that takes care of logging on for you (logging onto networks can be difficult, sometimes people report to me that they never did get logged on). While they seem to have signed up a number of wifi networks, some of which are operated by telcos, it seems like there are more and more free access points (in the US, not sure about other countries). Competing against "free" is very difficult. Dave Date: 20 Mar 2010 17:57:30 -0000 From: John Levine <johnl@iecc.com> To: telecomdigestmoderator.remove-this@and-this-too.telecom-digest.org.

You can get Skype wifi phones that look similar to normal cordless phones. I know people who use them as their primary phones.

Thus, >the LEC is a party to any spoofing. Except that the CO switch can be programmed to know what range of numbers is assigned to the PBX, and to substitute the main number if the CLID is out of range. Some telcos actually do that, some don't.

If that isn't "rugged", I can't define it. My analogy of a sprinter vs. a marathon runner explains it, I think. A car battery can put out a LOT of current for a small amount of time, but doesn't have a lot of capacity to do it for very long, and is easily damaged if you work it too hard. Batteries, especially lead acid, can be engineered to tailor them exactly for what they're used for. Car batteries are designed from the ground up to give the starter motor a big jolt, and not much else [*]. Deep cycle batteries can't deliver the same current, but what current they can produce they can do for a long time, and they don't get wrecked as easily when drained. * [*] Of course, the few other things are important too, but they don't pull much current by comparison to cranking the engine. >I'd like to set up a ham radio station for "Field day" in June, and >claim the extra credit available for battery operation, so that's one >question, i.e., would a car battery work to power a ~5 amp load for >twelve hours?

Not Verizon here -- "former SNET land" means AT&T, just like for you. Think it's really "not getting the SS7 data"? or just not bothering to pass it along? And yes, our cellular carrier, like yours, is not AT&T (unlike yours, though, it's T-Mobile, not Sprint).
