Binders:

B/W 1-25
O/W 26-50
G/W 51-75
Br/W 76-100

And on and on.

FWIW Telco cable is built in 25 pair groups or binders. Any cable over 25 pairs will have binders which are the 25 pairs twisted and then wrapped in a multi-colored colored string (old days) or two colored plastic binders.

For example a pair in a 25 pair cable consisting of a black wire with blue stripe mated with a blue wire with a black stripe is pair 11. Now lets go to a cable with over twenty five pairs and lets say the same pair was in a binder/group wrapped with a brown/white string it would be pair 86. Make sense?
