Bill, the problem is not that the cordless phone base interferes with ADSL, but that I'm now getting unacceptable sound quality on the cordless phone. My question was, Does a specialized filter exist for cordless phones that use 43-60 MHz range. It must not be old enough to use 1.7 MHz, as it has 10 channels.

It's the DMS-500, but I think that the official designation by Nortel is the NT-500. mjc Date: Tue, 23 Feb 2010 07:22:43 -0600 From: Neal McLain <nmclain@annsgarden.com> To: telecomdigestmoderator.remove-this@and-this-too.telecom-digest.org.

Here's a snippet from a Word document I received; I copied it into Notepad, then copied the Notepad version into this message. If Bill doesn't "correct" it for me, you'll see what slanty quotes do: [quote] Please “don’t be a no show.” [unquote] Neal McLain ***** Moderator's Note ***** I've tried to leave the quote intact, but I had to edit the message since someone forgot to put "[telecom]" in the subject line. In case the editor and/or the reader's news/mail client doesn't reproduce the quote accurately, or renders the "incorrect" characters "correctly", the offending characters have octal values of 223 and 224, which are respectively, 147 and 148 decimal. Those are, of course, the "open quote" and "close quote" characters from the Windows-1252 character set. ISO-8859-1 doesn't have an equivalent that I could find: it does, however, offer «chevron style quotes». C'est la guerre.

Actually, there is a suggestion that this particular laptop was a in- school model and not supposed to be removed from school grounds; which would allow the webcam to be activated. Anyway, if there is no picture there may not be a case. Here are links to a variety of news articles discussing the case, along with quotes from lawyers, and the latest news (as of Tues 2/23): >From the NY Times: There is a news report along with reader comments, which include some from Lower Merion families. I thought comments #25, #38, #44, #47, #48 were especially interesting.

See: http://www.philly.com/inquirer/home_top_stories/20100223_Rare_ban_in_laptop_lawsuit.html >From the Phila Inqr Sun 2/21/10: Several lawyers quoted in the article had doubts in the case: Christopher Wolf, a Washington lawyer who specializes in privacy issues, said answers to such questions - and the extent to which the district informed parents and students of the webcams' use - are critical in determining if school officials erred. "If, in fact, notice was given, and if the computer was reported lost or stolen, and if, consistent with the notice, the monitoring system was turned on," Wolf said, "it would be hard to see how that would violate the expectation of privacy." Jeffrey Lindy, a defense lawyer whose son is a Lower Merion senior, said he doubts a federal crime occurred. "I think the federal case is going to go away pretty quick; it would be a defense attorney's dream because there is certainly no intent to commit a crime here," Lindy said yesterday. "Now, of course, the parents weren't told. That's not illegal, just stupid."

This morning I was in 2 state buildings, [both] in San Bernardino, Calif, and on each floor they had pay phones, [which] were marked Verizon, but I believe that Verizon sold that part of the business. So it appears they must get some use: a couple of them /were/ in use. -- The only good spammer is a dead one!! Have you hunted one down today? (c) 2010 I Kill Spammers, Inc., A Rot in Hell. Co.

They can vehemently insist all they like, but the facts of the case are that an assistant principal called the student plantiff into her office and TOLD HIM that they saw improper behavior by remote activating his webcam. Nothing to do with theft prevention since she knew it was him. More details indicate that the thing that "she knew he did" was eating a candy that looked (to her) like pills. Demon M&Ms! They are completely hosed here. Careers will be over at the least, and if discovery uncovers pictures of undressed minors, it will mean lots of jail time. What were they thinking even creating the possibility of remote access? Concerns about laptop theft are not going to protect them, as they are soon to find out. All it takes is one bad person doing what they shouldn't with that capability (i.e. the Ass Principal), and there's no going back. > There were to be only used in case the laptops were reported stolen > or lost, so to identify the thief (and that is a legal use).

These are the same kind of school admins that consider aspirin to be a drug worthy of expulsion.
