You don't need a BIX2a at all.

Just X-connect from your incoming pairs to the station wiring.

Let's say your incoming 4 pairs are terminated on a BIX1A or 1A4 and this is the top block (for arguments sake). The rest of the blocks are all station wiring blocks.

Just loop your lines from the first 4 pairs on the top block to the lower blocks and keep looping. This is NOT my recommended way of doing it, but it is the simple way for you to understand.

For that matter, the INCOMING cable doesn't have to terminate on a BIX4A either, it can terminate on a regular BIX1A. You don't even have to loop it to the rest of the block. Depends on what you're trying to accomplish.

You also shouldn't need a BIX punch down tool to terminate jacks, unless of course you're using Nordx jacks.

Above all else.....make sure your bix blocks are identified with the proper designation strips, and each wire is identified accordingly.

and if you are looping your cross connect between spots on the bix make sure the lines on the circle on your tool are perpendicular to the tool and not paralel, that way the tool wont cut the wires

By all means.....USE THE RIGHT TOOL. (Bix16a)

You might want to pay Jay to go over and set this up for you. He'll have what you need and do the job right. (The tool alone is $75 +/-)

OK! Now I get it ...

Thanks to these explainations and to this particular link , I finally understood where the jacks connect to (it WAS obvious, but my brain wasn't catching for some odd reason).

So you basically said to punch in the x-connect wire on the same position as the incoming line on the BIX1A and then loop on the first modular jack block (BIX36D for example). Then at the end of this block, just keep looping on the 2nd BIX36D, so on and so forth, until I have x-connected all the desired modular jacks.

Now since this is NOT the way you would recommend, and since I think I'm starting to pick up on the concept now, what would be YOUR way of feeding 20 drops with 1 incoming line from the demarc?

I'm not entirely sure why you would use a 36D in your situation. If you're planning on crimping mod plugs on the end of any cables you're going about it the wrong way. Probably the most important thing to keep in mind is that your station cabling is all terminated on the back of the BIX rails. I usually describe this as the permanent cabling, which includes whatever cable you bring from the demarc. The front of the BIX rails is where you use jumper wire to cross-connect your lines from the demarc to the station cables. In this way you can think of the front of the BIX rails as being for temporary connections.

Looping a single line to 20 locations can be done several ways. If you understand the basic concepts, you can figure out how to use a 1A or 5A rail and a bit of jumper wire to give yourself one rail with the same line on 20 positions.

Alright, final attempt... I think I really got it now.

Just noticed on the diagrams that the demarc line ended up on the back side once you flip the BIX rail after cutting the wire... which makes sense now as I though the back side was never used on these diagrams.

Bottom line, I terminate the demarc on the back side of a 1A rail, then terminate all my 20 station lines (2 wires required only for regular voice lines) on the back side of 5A rail. Then using x-connect wires, I distribute the demarc (front of the 1A) by looping 20 times in the front of the station wires (5A rail).

And if I follow the same logic, I could distribute another pair from the same demarc on a 2nd 5A rail for the station lines of the second "house unit".

I know you said I could use just 1 rail, but since I'll need lines for the second house unit as well, I figured I might structure it a little better by using several rails.


...
Please tell me I got it right this time

Pretty much have it now.

Just to point out that when you X-conn from the D-Marc to the 1st Bix 5, on the back of the block, you'll see 5 "groups" of 5 pairs. Connect your jumper to ONE pin of each group. That will give you all 25 pairs to X-conn from.

Do the same for each line. Then go from those blocks to the station blocks....ONE pair from the 5a to each Station jack. Don't loop them. The reason is if if you want to change one jack later from say line 1 to line 3, you pull the jumper and swing it to the other BIX5a block.

:read: As I stated B/4....LABEL THOSE BLOCKS, not only for you NOW, but the next 20 or so techs that will follow you later on.
