(The line sequence arrangement of the large logarithmic cable of the telephone is very practical for colleagues who engage in integrated wiring. I found this with great difficulty on the Internet. I would like to share with you some of the extracts as follows: Basically, 25 pairs are used as the basic unit, and the cable has five basic colors. The order is white, red, black, yellow, and purple. Each basic color also includes five colors in the order of blue, orange, green, brown, and gray, that is, all line pairs 1 to 25 are sorted as white-blue, white-orange, white-green, white-brown, and white-gray; red Blue, red-orange, red-green, red-brown, red-gray;...Purple-blue, purple-orange, purple-green, purple-brown, purple-gray...)
