The color scheme is easy to understand if one is familiar with their primary and secondary colors from both the old and new systems. It's still all the same with the exception of violet, which makes sense why they chose that color because it's not represented in either scheme, and it would be confusing as hell to use the same color twice. I did not know the order of 25 pair until I watched this and saw how relevant it is to both systems. Great video guys.
Definitely start from the bottom and work your way up. Then the wire is already out of the way to lay down the next pair. Teaches you to master the code. I also always separate by primary colors first, violet of course! Let the tool do the work when your terminate and keep that tip sharp. :)
I go to ATC in Virginia Beach VA and we learned this a couple months ago but I'm taking my OSHA Certification test either next week or the week after so this is a great recap if its on there!
He should have twisted the end of the cable to keep them from unwinding. Also you ALWAYS start from the bottom up. That way you don't have the ones on top getting in the way.
I'm wiring up a pipe organ which makes heavy use of these telco cables to power 12 vdc relays and valves, but the number of terminals never matches the available cables which is a pain. the 50 pair cable works but lots of extra wires left over. The connections don't use "pairs" but there's usually 61 valves or 73 valves each needing a wire. So I've started at one end of the windchest where the largest pipes are, note C-1 and those valves get the white/blue wire, and the next pipe C#-2 gets the blue/white wire since they are next to one another and less untwisting of the pairs needed. I need to connect mechanical relays to these with a junction box, I decided on two 50 pair "66" blocks with 6 rows across each, installed side by side to have enough terminals for the wires for one chest, but since there's 61 relays x 2 I actually need a couple of 25 pair blocks as well for the one chest, and two more 50 pair and two more 25 pair for the other chest. I am using custom 32 pair connectorized cables with AMP plugs. It will be a lot quicker and easier than making a pin board and soldering wires to brass pins! You should see how they wired up these 1930 era pipe organs using hundreds of green cloth covered wires throughout, the keyboards were a work of art with the wiring with each key having 3 wires, they installed the wires in so even, straight rows in a fan pattern. Unfortunately it all had to be replaced with modern telco wires due to age.
If you know how to punch down ethernet cables for telephone, this is super easy to remember. The only thing that changes is the addition of four new primary colors and the fifth secondary color which is slate.
Your end result looks ok, but it's much easier to fan the cable in from bottom to top, of course starting with slate/violet conductor on the bottom pin and ending with white/blue on the top pin. That way you are not always having to move the previous pair out of your way to lace in the next pair.
I was hanging over a camera and working around the equipment while I was demonstrating punch down on a 66 block. You're right neatness does count, but sometimes you bring the cable in from the top. Sometimes it comes in from the bottom.
Proper installation separate1 group at time per ma bell training tech. Let other pairs hang down out of way. Some ppl start at bottom. Tried it once very awkward.
How would I do this with individual cat5e cables from each office going back to our wiring closet so Qwest can bring in the lines and connect to them. Should I use a 110 block and if so how is that done.
If it has four 25 pair groups (binders), it has a total of 100 pairs, not 100 "wires". Its called a 100 pair cable. Each binder will be wrapped in a colored thread to define the binder. white through yellow. in the case of a 100 pr. cable.

Bought a pair of 66-blocks, some mushrooms, and bridge clips from you guys because of the high quality videos on here. Great prices too!

Excellent video, very well done and great explainations.
Thank you for making this video. I am taking a Telecommunications and Data Cabling class and I have to do this for a project. thanks again.
@jollypop2008 No, that is a 66 blade.
Very good. Thanks for the video.
FANTASTIC VIDEO
Thank you for sharing.

sir aim a new for the telecom tech. i want to learn how to pucth from primary mdf to secondary mdf and how to put a jumper wire ?thanks for helping me
nice. so deep ROCK ON
isn't it called Tip and Ring colors, not primary and seconday?
***** No, i've always heard it as primary and secondary
Tip and Ring is the Bell System Standard.
Can these be used for Gig Eth use?
for ethernet use 110 blocks
If U go from the bottom up ,,, Its much more easy...
Always learn your code backward. then its not in your way...
My networking teacher has 4 25 pair cable, i think..... it has 100 wires. 4 sets of 25 pairs.

Why Run Backwards Young Virgin. Bl O G Br S.
Yes that is the color code. Did I miss speak on the video ??? "Young" ? 40 years in cabling. "Young"🙂 thank you!
