Seriously? I'm suggesting the outlay of more than a year's full college tuition is nothing but cruel punishment, both of the 17-year-old being incarcerated and, even more unjustly, of the tax-paying public who are footing the bill. I apologize for having been too opaquely curt in my first response. Cheers, -- tlvp -- Avant de repondre, jeter la poubelle, SVP.

Yes, of course. Are you saying that middle class suburban teens are saying "oh, the worst that will happen is that I'll spend a year in jail"? >will deter others unfamiliar with his case from doing what he did? >Seriously? I don't understand what point you're making here. What's the relative deterrent effect of a one year sentence that others haven't heard of and a 50 year sentence they haven't heard of? I certainly hope that texting teen went to jail shows up in the drivers' ed curriculum. R's, John

(use "AC volts" setting, try the probes in both > combinations) The telco guy came before I did all that. He measured the ringing & non-ringing voltage as DC! He claimed twenty-mumble years on the job, had never been asked to deal with ring voltage, insisted that the only meaningful measurement was DC voltage. 52 VDC at the demarc (NIJ? Outdoor thingy between my wires and theirs) and at the cabinet 5 miles away. Slightly higher when ringing. Dismissed my measurement of 18 VAC when ringing as not meaningful. He went away content that there was no problem leaving me confused. Happens that phones rang as they should when he was here. That's all contrary to what y'all have told me here (measure AC ring voltage at, should be 40V to 90V). Did I draw a complete dummy tech? It's not as if a 20+ year guy has never seen a 2500 set or a phone that has a "real" ringer. There are folks here with old rotary-dial sets. Oh, well, I'll follow your directions, Robert, and file results for future reference. Grumble...mutter... Tnx, -- Mike Spencer Nova Scotia, Canada

Borrow a "Genuine Bell Canada" phone, and plug it in at the demarc. Don't use your own phone: you need a "Known Good" instrument for this test. If the problem persists, it's their trouble. If not, it's yours. ("Genuine Bell" is important: phones from other manufacturers often have non-standard ringers that the techs won't trust. When you can point to a label that shows it is/was their instrument, they'll be less likely to blame the phone.) 2. If the test shows a problem in the telco network, I suggest you A. Send a letter to the Nova Scotia PSC, and ask any neighbors who have had the same problem to co-sign it: Public Service Commission 1800 Argyle Street, 5th Floor PO Box 943 Halifax, Nova Scotia B3J 2V9 B. Contact your MP, and complain at length about poor service. It's important to use longhand when you write, because politicians place great weight on hand-written letters. HTH.
