plenum tye wraps are very expensive also, over a dollar US apiece.

are all the drives on the same system? bad cabling shouldn't crash drives unless it's on the power supply or grounding. Sounds like an interesting problem to resolve. Give a little more description of the problems/systems/location.

just for one time benchmark or short-term use don't forget the rental option. Probably $100 US or less a day. Most telcom supply houses have them.

most people will probably recommend you leave the 66 block in place and use it for cross connects. Makes for much easier changes and trouble shooting in the future. It would be very easy to take each cable and crimp the appropriate connector on it but using the 66 block give you more flexability...

those fiberglass splinters are nasty.

you will get about 8 db loss from the splitter itself. Go ahead and install it and see if it works. Then think about amps. You will probably only need it for a few drops anyway.

The package systems are simple, straight up plug and play. Thats just the computer, drive and software. A neat feature is the ability to only record when there is movement. Keeps you from using to much drive space.

For longer cable runs alot of power supplys have a higher voltage option 24vdc-28vdc. Many cameras work on ac and dc. Some of the power supply systems sold by security vendors are pretty slick in offering multiple voltage ac/dc options to each camera. It's not uncommon to have cameras from a few...

larger yer cable, longer it works. Lower number- bigger conductor will work better.

25 pair terminated properly doesn't need a service loop. You ever see the telco guys leave one ?

I agree with bobg1. There's obviously something majorly wrong with the conduit and even if you got the 25 pair out who knows if the conduit is usable. Before you get too much time and effort into the pipe investigate alternatives.

I agree with dex, loop timing would be the norm and might not fix your problem. Check your fault logs and try to isolate problem to particular trunk, line, phone or card.

this problem makes no sense at all. I can't believe all cell phones don't get thru with dtmf. I think you have to narrow down to which cell phones because to the network a cellphone is just a phone. If the call is picked up can you converse with the cell phone user so you just can't blame it on...

ThePhoneGURU pretty much said it all.

I'm assuming the correct way means maintaining wire twist all the way to the punch and headroom is high end bandwidth.

he should build some sort of wire supporting structure on his house and then extract the pole, with or without their permission.

if you are just cutting over the c.o. lines from one provider to another (typically with like #s) its a simple matter of swinging the 2-wire x-connects. You don't really have to know the phone system, just know what the wires you are moving do, ie c.o. lines. If theres a problem, move them back...

move your recording device to another line. If the hum is still there fix your equipment.

cat-6 will increase your material cost 50% minimum. It will give you more thru-put and speed but honestly I can't type that fast.
