How many CAT5 ?

[millero]

Really?

I was taught that all conduit passing through a wall was required to have the void space filled with firestop.
Maybe thats just for schools....

carry on.

that may be for schools and it may be for other places too, but ive only had to do it when i'm going through a firewall (we dont have firewalls between every room).

Just a tip, when trying to use pull string on long runs you can use a shop vac to suction string from one end to other.

you can buy little foam things called a "rat" to attach to the string to suck through the pipe. they come in all different sizes.

Yessir

The rat is cool...........

Phones only use one pair and ethernet only uses two pairs. You don't need a separate cable for everything, if you get in a pinch.

THat's why I was asking, 2 Phones and the internet off 1 peice of Cat5. You could save on pipe size and footage of wire that way.

You only have to firestop when penetrating a fire/smoke rated assembly, i.e. wall, ceiling, etc.

We have 1 hr ceilings throughout the whole job, (2) 4 hr masonry fire walls, and lots of other 1 hr fire/smoke walls.

Of course it's not a bad idea to do it even where it is not required by code.


As for how many you can run, it's been covered. I think, a good rule of thumb would be not to fill the conduit more than 1/2 - 3/4 full, but I'm not an electrician.

Don't forget many phone systems are moving to VoIP so you should plan on having an IP connection for each stand-alone phone and one for each computer with a phone next to it.

Most of the newer IP phones have an extra port on the back of the phone to connect your Computer to so instead of using 2 lines only one is necessary.........

if the installer doesnt understand vlan's, he will need 2 wires.

dont ever do that with the network cabling.

lollollol......

Look at what I said. I said an IP port was needed for a stand-alone phone. And one for each computer with a phone next to it.

Even without QOS, most business networks can handle VoIP on a shared data network.

just because it works, doesnt make it correct. voice should be separate from data.

Why not? If you only have a limited amount of wire, it only makes sense to use what you have. On short runs, you won't have enough crosstalk to effect data or voice, even with analog phones. Splitting up a cable and using a few unused pairs is a lot more cost efficient than ripping out and pulling more copper. Why not use the superfluous pairs if you have good performance?

Do all of you work for cable companies?

serious.

You're right.

Please enlighten me as to why?

I have done it and our engineers have tested as well, there is problem with it. We have several thousand houses in our fiber neighborhoods and ALL have their internet run in on a phone line with split pairs. Ethernet cables for internet only are only useing two pairs(green and Orange) in house with dialtone the blue handles the DT and the green and orange pairs handle the data, with the brown as a spare.

Yeap, I do. I work for a local private Communications company we handle Phone, Tv and internet.

No I work for a school district currently,worked for 2 others as well and ran/installed cabling/fiber-optics for 1 college............

If you only knew how many people that affect my job that don't comprehend this.
