Information outlet locations
The customer or marketing representative must provide floor plans showing the information outlet
locations and types (flush- or surface-mounted) required. The floor plans must also show a complete
overview of all conduit and cabling facilities in the building.
Site, satellite, and adapter locations
Use the following information when determining site, satellite, or adapter locations.
•
Keep the number of locations to a minimum.
•
To minimize the station wiring distances, centrally locate the sites/satellites, or adapters among
the information outlets.
•
Site/satellite locations must be easily accessible and contain AC-powered receptacles.
One 258A/BR2580A adapter is required for each 25-pair station cable containing 4-pair station circuits.
One 356A adapter is required for each 25-pair station cable containing 3-pair station circuits. Hardware
requirements are the same as for the equipment room.
Sizing 4-pair station cables
Use the scale of the floor plan to determine the approximate length of the station cables required per the
standard SYSTIMAX wiring concepts.
Sizing 25-pair and multiple 25-pair station cables
Use the scale of the floor plan to determine the approximate length of each 25-pair station cable. The
cables must be selected and properly sized to make maximum use of the hardware at the equipment room
or satellite location.
Use 25-pair B25A cables to connect adapters directly to the MDF or satellite location. Staggered-finger
cables, equipped with factory-installed 25-pair connectors at both ends, should be used when multiple 25-
pair cables are used between the equipment room or satellite location and the adapters. B25A cables are
required at the equipment room or satellite location to connect the staggered-finger cables to the 110-type
terminal blocks.
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.
