There are so many lines in the telephone communication cable, how can you tell the difference?
You should be a new employee in the communications department. I'll tell you how to tell the difference. The cable is divided into 5 main colors and 5 sub colors. The main colors are white, red, black, yellow and purple. The secondary colors are blue, orange, green, and ash. Each main color is assigned a pair of 5 pairs, that is, the number of the 5 phones. All finished 25 to 100 on the cable, if it should be distinguished by color brings. The 25 pairs are wrapped in a ribbon. Ribbons are also colored. What colors are they?. I took the thickest cable, 600 pairs. It's not difficult to distinguish. It feels easy. As long as the color is good, OK.
