Determining Block Quantities
The following computations show how the field requirements are converted into terminal blocks.
1. Green Field
A. Number of Cable pairs terminated =
B. Number of cross-connect blocks required =
2. Yellow Field
A. Auxiliary cabinet terminations:
12 cables
2 cabinets x

B. CC cabinet termination:
12 cables
1 cabinet x
cabinet
C. Total pairs
D. Blocks needed:
