No kidding. I used to pass the emails along to the end users. Not any more. After this last worm (MyDoom), I became fed up with having to explain to the users why they were receiving the emails. As the parent poster did, I just throw them away. Problem solved.
As for the people who allow their AV gateways to send back auto responses, they should be shot. Every time I receive one of those emails from postmaster@somewhere, I fire back a nasty email tell them to cut it out.
Typically the fire alarm circuits will go into some sort of alert mode if a loop is whacked. A contractor or two did that where I work during some of the construction. The alarm didn't go off, but the monitoring company called and notified us. Hell, if one of the two phone lines the alarm uses to dial out is cut, it uses the other line to notify the monitorin center.
This would have to be for big distribution lines. The 120/240 feeds to houses are made out of cable that simply has a jacket that withstand moisture/rotting/UV. Hell, even the 13.8 kV feed to where I work looks like it uses the same cable, albeit a little heavier. (I know because we dropped a phase a couple years ago, a weakness in the wire finally burnt itself out.)
I've always wanted something like this that "extended" a phone line.
Something like this: You plug this magic box into your phone line & broadband at home. Then then take magic box #2, give it a broadband connection anywhere in the world and it's magically a phone jack from your house. Does anything of this sort exist?
Wal*Mart sells something like this as well. I believe it's called the "cellular home base".
It was $49 or so.
It works on my Nokia 5165, but not my 6360.
Works pretty slick. Mine has a loud buzz in it though.
If the booths lack electrical power, just power them via an extra pair of copper that's already running to the booth. We've got a few ISDN phones in our building that need a third pair of copper just for this purpose. The power supply's in the phone room....
The phones do not work ad-hoc (phone to phone).
You must go through a cell site for call setup, handling, billing, etc etc etc....
If you still want to be annoying, buy a set of those cheap family radios to talk back and forth...
I'll second that. I grew up in Renville County, Minnesota (pop 16,000). It supposedly has some of the best farmland in the state. Nearly all of the economy is based on agriculture.
Anyways, using GPS tech. on tractors is nothing new in that area. I believe the soil service coops have been doing it for years. I also remember there being a class in high school that taught use of GPS technology on the farm, I think our school had received a grant for it.....
Sirius Radio will use the in the 2320.0 to 2332.5 MHz frequency band. XM Radio already uses the 2332.5 to 2345.0 MHz frequency
It takes 12.5Mhz of bandwidth in the S-band segment. 2332.5-2320.0 = 12.5
In-building short-haul fiber optic transceivers typically use LEDs [Light Emitting Diodes] to drive the fiber. This is almost akin to looking at your alarm clock.
It's still not a wise idea to look into the fiber, as you might not know what type of light it's carrying...
I'll second that.
Where I work, we use cat5 for both voice and data.
The only difference between the two are the colors of the cables and jacks. We usually can get away with plugging RJ11 (2 pair telco) wires
into RJ45 (4 pair ethernet) jacks, but on occasion pins 2 & 7 will get pushed down in the jack and pop up in the wrong position. This typically only happens when I use and RJ-11 splitter. BTW we are using Lucent/Avaya jacks.
So what I do instead, is recycle the old surface mount boxes and parts of old patch cables to create RJ-45 to RJ-11 assemblies on the cheap. Works well when I need multiple analog lines to an office that only has one RJ-45 for voice. I build a breakout cable on the patch panel end (normal ethernet config on one end and an RJ-45 end on each individual pair). This assembles the individual analog pair onto one cat5 cable. At the other end, I do the same but use the surface mount boxes. Sounds complicated but works slick.
The local telephone people don't understand it though...
Exactly. I use some command prompt stuff to backup the Win9x registry when I visit people's workstations. It's like rocket science to them.
"Wow, you're smart"
Just part of the job ma'am...

"FM" is a modulation technique, not a frequency range. See http://en.wikipedia.org/wiki/Frequency_modulation
Must be fun trying to stuff the birds into the card readers....
KVM switches anyone?
Electronical?? Must be a new word.... Sorry...I just snicker when I hear people say that.
Did you use a crossover cable to plug your switch in? Unless your admins lock the ports down by mac address, you shouldn't have problems..
I'll second that. Those antennas are the best I've seen for FM broadcast reception. They are also easy to modify to create a cheap 2-meter beam.

There's a drive-in theater 70 miles or so west of Minneapolis, MN. It's actually doing quite well. They have a cheesy website _HERE_

I'm sure the poster meant 146.64, which is in the 2 meter amateur band and is one of the frequencies set aside for repeater use.... Dave KB0WJP

I am the inventor of the question mark. Pay me royalties, or I'll see you in court.
I thought there were building/fire codes that exist where you cannot be locked into a building. Think Triangle Shirtwaist Fire

For phone, you could probably settle for Cat3 for cost reasons
Can a person even buy Category 3 cabling anymore?

People do that where I work as well. Subject line, blank email body, and Word attachment. They like the pretty clipart......
