For example, in most of Silicon Valley the magic number is 760 although at least one town (can't remember which) uses 890 More trivia: Most CO's have various service numbers that the linemen can dial (from your instrument) to check your level, etc. If your exchange is 656, for example, you might find that dialing 656-0020 gets you a pulsing 1004 Hz. tone. It will have been at 0 db at the CO; any less is the loss in your line. There are also numbers that give you a terminated line (good for balancing bridges) and a sweep tone. No, it is *not* illegal for you to dial any of these; they exist so that people who know what they're doing can make adjustments to (for example) audio conferencing equipment. (and, of course, primarily for the telco service people) Anyway, try numbers of the form XXX-00YZ where XXX is your exchange, Y is some digit 1-9 (usually low), and Z selects the particular test function (so usually Z can only be 0-3).

Add it to your .signature and you too can help overflow the NSA's ability to scan all traffic going in or out of the USA looking for "significant" words. (This is not a joke, sadly.)
