Once I heard a phone man name all twenty five pairs in >a cable and their associated partner.....purple and gray/??? and ???..... >then we get into the slates (stripes)...can anyone reading this name all >twenty five pairs (fifty wires) and the 'proper' color combinations? PT] It's really pretty simple: There are 5 color groups white,red,black,yellow,violet In each group there are 5 pairs blue, orange, green, brown, slate For each pair, the wire that is mostly the color of the group goes first. For example the 1st pair is White/Blue then Blue/White. Here's the list: white/blue blue/white white/orange orange/white white/green green/white white/brown brown/white white/slate slate/white red/blue blue/red red/orange orange/red red/green green/red red/brown brown/red red/slate slate/red black... yellow... violet... That will give you 25 pairs (50 wires). To get more than that, for instance in a 1200 pair cable. Each set of 25 (colored as above) is wrapped with a colored ribbon. The 1st 25 pairs get a blue ribbon wrapped around them. The 2nd get an orange, the 3rd get a green ... and so on. I've never installed a cable with more than 100 pairs, so I don't know how the coding goes after 125 pairs. I'd assume it's fairly straightforward.
