PT] > Hmm... I just learned this a few days ago when I had to punch down a 25 pair cable... Basically, they're grouped in sets of 5 pairs. The pairs are colored blue, orange, green, brown, gray. Each set of 5 pairs has one pair of each color. The sets are colored white, red, yellow, black and purple (I think that's the order at least). Wires in a pair are first the first color dominant and then the second (they're all striped wires...) So, it goes like this... blue-white, white-blue (first color being the dominant one) orange-white, white-orange green-white, white-green brown-white, white-brown gray-white, white-gray and then blue-red, red-blue green-red, red-green... and so on through all 25 pairs. For 50,100,125... pairs, I was told this same thing was repeated for each 25 pairs and the whole thing was wrapped in still different colors. That scheme I don't know though.... --Mike Richichi, Student Telecom Support Specialist, Drew University, Madison, NJ, USA. MRICHICH@DRUNIVAC.BITNET
