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.
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 twenty-fifth pair in all
cases. If not, it must be allowed for.
Voice and Data Terminals
The system can connect to all DTE terminals and have RS-232 (or EIA-232) or
DCP interfaces. Tab le 2 -4
lists some of the terminals that can connect to the
system. Contact your Lucent Technologies representative for more information.
