CO/PBX Line Cutdown Sheet Configuration (Figure 3-12, Figure 3-13)

Due to the flexibility of the system's universal blade slot configuration, standard cutdown sheets for CO/PBX
line cabling do not apply.
✎
Note: The order in which the trunk blades are installed determines the assigned line circuit number.
For example, if four 4COIU's are installed in the Controlling/Base chassis in the following order, the following
numbering plan would be in effect:
To determine trunk assignments for the system cutdown, the installer must identify the following in order:
●
Order of installation
●
Chassis (Controlling/Base, Expansion)
●
Slot used
●
Blade type (4COIU, 4COIU with 4COIDB, 4TLIU, etc.)
●
RJ61 connector
To determine where any group of lines are installed, note the order of install, chassis, and slot.
On the following page is the line cutdown sheet (Figure 3-12). Make as many copies as you need. Be sure to
keep careful records of your installation. Refer to the sample line cutdown sheet (Figure 3-13) if you need help
