yeahhhh, that example I gave was really oxidized. It seemed as if the copper was oxidized and the steel under the copper coating was rusted through.

Oh, by the way, since you have 4 conductors in the JKT, you should splice and terminate all 4 of them when you do this installation, to create a 2-line jack (RJ14W).

You might need to use the second pair for a two-line phone, and if you make the splices now, you won't need to come back and open the jack again to make the connections.

Since the writing is old, I'm trying to get the most out it, and the best splice out of it, I'm my own customer,lol. I just thought that there were jacks that would off accommodate the older thicker write, but it seems like I'm starting to lean towards stripping the jacket from the pairs soo that they would be a little bit thinner to punch down. I'm hoping I can get att to rewire and condo association to pick up the tab, I'll even supply cat 5e in plenum if need be, as I have plenty off it, even though you guys consider it a waste or overkill for that purpose. I will definitely punch down the second pair into jack during this project.

I might be wrong but I think the jacket is what mainly keeps it in place after the punch down.

Yeah, insulation is fairly important in holding the wire in place when you use an Insulation Displacement Connector. Stripping the insulation off so you can terminate is a bad idea.

My advice would be to use (no surprise here) a screw terminal jack.

there seems to be a lot of that here recently ....

Cepega a faceplate with screw type terminals is the best product here. Not sure why you want to use a punch down jack so badly??? A screw on terminal will function just as well and will not require any goofy and rigged up looking splices just to accomodate a punch down jack of some kind. I doubt anyone here who hoes this for a living would resort to splicing a peice of cable instead of using a faceplate with terminals. :shrug:

It is actually very clearly stated in the BSP for 630 type jacks that they are not rated for use with JKT wire. You'd be wasting your time and resources in trying to avoid a screw-terminal jack. That is the only reliable means for terminating conductors in type JKT cable.

Stop it Ed! I didn't get issued a BSP. However, I do have both a GTE COEI and Station Installation manual. We had our own goofy jacks, wall plates, and handsets.

The only time we do that is when the wire is the wrong type, or can't be re-run, or is too short, AND we need to use a keystone jack with IDC.
