I will have someone guide me. Hopefully. I am talking with someone, but I want to learn as much as I can.

Is there a difference if the wiring is terminated 1-6 on the left, 7 to 12 on the right side? VS the way I describe it? I though that was what "grider" meant, I misunderstood.

I am having trouble understanding what the second second color sequence in a 25 pair cable:

Pair Primary (tip) Secondary (ring)
1 White/Blue Blue/White
2 White/Orange Orange/White
3 White/Green Green/White
4 White/Brown Brown/White
5 White/Slate Slate/White
6 Red/Blue Blue/Red
7 Red/Orange Orange/Red
8 Red/Green Green/Red
9 Red/Brown Brown/Red
10 Red/Slate Slate/Red
11 Black/Blue Blue/Black
12 Black/Orange Orange/Black
13 Black/Green Green/Black
14 Black/Brown Brown/Black
15 Black/Slate Slate/Black
16 Yellow/Blue Blue/Yellow
17 Yellow/Orange Orange/Yellow
18 Yellow/Green Green/Yellow
19 Yellow/Brown Brown/Yellow
20 Yellow/Slate Slate/Yellow
21 Violet/Blue Blue/Violet
22 Violet/Orange Orange/Violet
23 Violet/Green Green/Violet
24 Violet/Brown Brown/Violet
25 Violet/Slate Slate/Violet

What are they? Are they actual cables? How are the color code being use?

For terminating cabling on 66 block, do I need to worry about the 25 pairs color code?
