Greetings

I am doing both the data and voice wiring for a client who has just moved into a new building. I have never done voice wiring before, but i cant imagine its any harder than Ethernet.

ANYWAYS, the situation is this. I'm doing the wiring for the phones, another company is doing the phone system itself. They will be taking care of things in the server closet where the PBX will be. All i must do is run lines to each office from that room. I'm not messing with a 66block or anything crazy like that.

I have not found any good guides on this topic. I must be looking in the wrong place.

The CAT6 has already been purchased, it's what i'd like to use. Also picked up the appropriate amount of RJ-12 110 Type 90 Keystone Jacks. I belove these are correct.

Am i on the right track? I'm trying to learn as much i can on the topic as well as get the job done.

Thank you in advance.

Yep, you're not looking in the right places, try Leviton. Now, here's the problem. You're not "messing with a 66 block" so how do you propose to test your installation? You're going to terminate one end and leave the other one just hanging?

My abosolute rant is you do the whole infrastructure or leave it unwired.

Cat6 for Voice? :bang: :bang: Glad it's not my money someone is spending.

I suggest you contact the company installing the telephone system & see what they expect for wiring, jacks, termination.

Is the SV8100 running VOIP stations or TDM (digital) phones.

If it's just TDM then CAT6 is a total waste of time and money.

Like MooreTel said, contact the PBX installers and see what they expect to have in place.

If you're terminating it all on patch panels and they are using TDM phones then they'll need to break the PBX out on a patch panel as well and someone will have to supply patch cords, better make sure they are CAT6!

I'm assuming you aren't punching down the phone room side into anything. If you aren't, make the entrance into the phone room neat, and allow lots of cable for the phone guy to route nicely into his blocks. Remember that he will come in from the BOTTOM of the jacks, so if the cable is currently coming into the room from the ceiling (which is fine), give him plenty of cable to run into the jacks. If he's willing, have him look at one or two runs before you run the rest.

Make sure he sees what you did with the RJ-12 jacks so that he punches down the wires to match on the punch down blocks.

If you are punching them down to a patch panel or something, then I'd probably put RJ45s on both ends so they could be used as network jacks if needed - after all Cat 6 would handle that fine.

I do agree with everyone else - having a split responsibility job like this will get the phone guy off the hook if anything doesn't work, even if it is his fault (do you have the equipment to test his punchdowns - so it's his word against yours). Be prepared to pay him to fix your work (even someone that does this all the time would have one or two bad punches on a job).

I'm a CG too - I won't run wiring at all unless I run both ends, am in compliance with local laws (you may have to be licensed or have it inspected), and have the ability to test the wire after it is run. Otherwise I will always have a nagging feeling in my head that the thing doesn't work because I screwed up the wiring. It's a nice feeling to know the wiring is not the problem - which you get if you test it (or, better yet, certify it).

I also think cat 6 going into RJ-12s is a waste of money and time. Cat 6, with the number of twists it has, is a lot harder to punch jacks onto than Cat 3 is. Time is money too. And the cat 6 isn't going to sound any better on the telephone than Cat 3. My advice would be to buy some boxes of Cat 3 for the phones and keep the expensive Cat 6 cable around for the inevitable additional ethernet drop that someone will need. Why waste the good stuff on telephone? That said, it will work for voice circuits just fine - but it's like paying for overnight shipping when you don't need the shipment to arrive for another month.

First, what is this RJ45 stuff. You mean 8p8C jacks and plugs right? RJ's are wiring standards not connector types.

Second, I agree, find out what the system installers want - it will save a bunch of people work.

Third, Cat 6 cabling - Unless you are specifying gigabit switching to the desktop - is just wasting the customers money. As it is, over moderate runs, Cat5e will handle gigabit speeds too. In addition, Cat6 uses a larger gauge wire, so you need to terminate it with more expensive jacks, and use better patch cables. Other than the annoying twists, it should punch into a 66-block. If you are going to punch it on a 5e panel or 110 bridge, you will have a 'fun' time since the wire is thicker and so is the insulation.

Cat 5e and 6 both have the same distance limits for gigabit. Cat 6 has greater bandwidth though, so future technology might work better on it (I don't know if 6 can do 10 gig or not, but 5e can't).

I'm kind of new in the industry...shy under a quarter century...however, I have heard of, but never seen, an RJ-12. :shrug:

Remember, there are standards for a reason.

First go find out what kind of phone system is going in and what the telecom installers require and then come back here so we can help.
