Hardening outside phone line for alarm system

I would suggest leaving the existing wiring exposed.

Add a conduit from box to house to carry the real, "live" phone wires. A burglar may be smart enough to cut the phone line first, but it won't be the actual phone line.

If the line's cut, how's it gonna call?

Around here the "box" is high up on a "telphone pole" (well it carries hydro-- electricity to those south of the border-- as well). Ie, there is no ground level box. You have to run the phone line either down the telephone pole, which is the telephone company's property and they really do not like you fooling with it-- or down the house.

]Another problem with leased line security is most telco's don't want to ]provide the dedicated copper pairs any more. They can make far more ]profitable use of that single pair as part of the dial-up system. Finally, ]new outside plant lines are gradually switching over to fiber optic which ]does not support inexpensive line security devices.

Except that now they can actually use that copper pair for far far higher data transmission rates-- eg ADSL modems, etc. Thus one could imagine putting an ADSL type signal on the line to the phone company-- or if the user uses ADSL via the user's ISP-- and monitoring that for disruption.

Most homes have two lines (ie two sets of twisted pair) coming in anyway

I'm trying to figure out how Mexicans use water "hydro" for electricity.

Quite right. As more people start using ADSL and even SDSL, perhaps the alarm industry will begin to take advantage of its capabilities.

It's called a "dam"

Damn. That's funny.

Not sure what part of the above you are referring to, but in much of the Northeast telephone wires come in on "telephone poles" and the wire goes aerially to the drop on the side of the house...

Up here in Canada, we refer to "hydro" as the electrical plant

ie: "How much was our hydro bill this month...."

.......or...........

"where does the hydro come in the house...."

And our power supplier is called Ottawa Hydro

So what do you call water, electricity?

Hydro and electricity don't mix.....

How do they get the water in those little wires? What do yous guys call that blue water in the crapper? Besides a good acid trip.... LOL

co-worker got woke a week ago by his neibor, someone had cut the neibors phoneline an attempted to break in to a window. The husband was away on business, I guess they may have though both were gone. Luckly she had a cell phone and called 911 when she heard a noise outside.

That's easy. Disguise your NID by relocating it or burrying it in a dry spot. Now setup a dummy NID with a very obvious phone line wire going to it. Wire that dummy phone line to a zone on your alarm.

Burglar cuts what he thinks is a phone line and the alarm goes off. Cheaper than radio or cellphone backup.

(An alternative is to wire the dummy phone line to 220V so the burglar gets dead if he cuts it. Just make sure it's not a lineman for the phone company.)
