Please log in for more thread options home. I have looked and looked and all I can find are over-complicated wiring diagrams that I do not understand. Please help me. First of all, I am not using Cat5 cable, just regular phone cable (I do not know what it is called). Each phone jack has 3 pairs of wires connected to it, but I'm only gonna use 1 pair right?. All the cables to the jacks and the demarc are already in place, I just need to connect them at the 66 block. I have all the tools I need. The 66 block supports up to 50 pairs (just like this one: http://www.fourpair.com/ccp51/media/images/product_detail/66Blockwebsm.jpg). Holding the 66 block upright and going from left to right, there are 4 places to punch down wires. The left 2 are connected to each other and the right 2 are connected to each other like this: 1. aa bb 2. cc dd 3. ee ff 4. gg hh 5. ii jj 6. kk ll 7. mm nn 8. oo pp ......... For the uplink to the demarc, there is 1 pair of wires. From the top of the 66 block, I ran one of these wires down the far left column and the other down the far right column, punching down the first 8. I then took one of the phone jack lines, used the blue and blue-white wires to punch down to the 2 center connections on the top row. I have a dial tone for the jack, but...... I get shocked when I touch the left and right connections on the 66 block at the same time. I must be doing something wrong. Also, I'm not using any of the bridge clips that came with the 66 block, so that also leads me to believe I'm doing something wrong, but the phone jack that is connected is indeed working along with my DSL. Can someone please explain how to wire this correctly? I just want my POTS lines to work without shocking me. I do not care to about using VOIP, Cat5, adding additional lines, etc. TIA, Jack | ||||||||||||||||||||||

The idea behind wiring blocks is to provide a permanent termination for installed wiring. You will want to punch down all 3 pairs of each of the 8 cables you have going to the jacks. The order for the first cable will be: white/blue to bb blue/white to dd white/orange to ff orange/white to hh white/green to jj green/white to ll Repeat the wire color sequence starting with nn for the second cable. Be neat. One side of your our incoming line will loop from aa to mm and on to all the left side connectors for the white/blue pair, The other side of the incoming line will loop from cc to oo and on to all the left side connectors to the blue/white pair. You will then use jumper clips to connect aa to bb, cc to dd and on down the block until you have installed 16 jumpers connecting the 8 phones. These clips make troubleshooting easier by allowing you to disconnect individual jacks. | ||||||||||||||||||||||

Thanks for the reply! I'm very sorry, but I still do not understand. I think I understand a little better though, but I still have a few questions. First of all, what is the difference between white/blue and blue/white, etc? Secondly, you said "The order for the first cable will be...white/blue to bb". In my representation above, "bb" represents 2 places to punch down. Are you saying punch the same wire in 2 places? Thirdly, if the incoming lines loop from aa to mm and from cc to oo, it seems a waste of time to punch down the jack lines in between. There's nothing to bridge them to. Lastly, if what you say is correct, then my 50-pair 66 block can only support 8 jacks? Is that true (for my case, where there is a 3-pair cable per jack)? Thanks again, Jack | ||||||||||||||||||||||

"If you look at the top 2 wires closely you will notice that one wire is mostly white with a regular band of blue. This is the Tip. The second wire is mostly blue with an regular band of white. This is the ring. Ok so the bands are kind of hard to see. But when seen in longer lengths and twisted, you can make out the colors easier. The wires are twisted to prevent the signal on one pair of wires from "leaking" into the others." > Secondly, you said "The order for the first cable

Since you will be using bridging clips you will only be punching wires on the outside positions. The inside positions are where the clips go. See en.wikipedia.org/wiki/66_block On the left side you will flip your punchdown tool to the non-cut side and loop the incoming line to all the leftmost positions matching the blue pair. Complete the circuit with clips. > Thirdly, if the incoming lines loop from aa to mm and

Like I said in the last post "The idea behind wiring blocks is to provide a permanent termination for installed wiring." Just because you are not using the other two pairs now that does not mean that they will never be used. The practice is to terminate all installed wiring to the block. > Lastly, if what you say is correct,
