Use the following information to determine the cable size (cable pairs) required for either 3-pair
or 4-pair circuits. Note the length and size on the floor plan to aid in the ordering and
installation of the station cables.
3-Pair Station Cable Circuits
To determine the size of station cables containing 3-pair circuits, multiply the number of 3-pair
circuits required at the satellite location by 3.5. Then, using the minimum size cable
requirement, round up the cable size requirement to the next highest available cable bundle size.
This will provide additional pairs for growth and compensate for every twenty-fifth pair in a
cable that is not used.
4-Pair Station Cable Circuits
To determine the size of station cables containing 4-pair circuits, find out how many
information outlets are served by the equipment room MDF or satellite location MDF. Multiply
the number of information outlets by 4. Then, using the minimum size cable requirement, round
up the cable size requirement to the next highest available cable bundle size.
NOTE:
This formula may not compensate for the unused 25th pair in all cases. If not, it must be
allowed for.
