Instruction manual

Control Unit
■ Group all 100D and 400EM modules together according to type,
whenever possible, to save time in system programming.
Each physical jack on the control unit is numbered sequentially from left to right
and bottom to top:
■ Station jacks are numbered from 1 to 144.
■ Line jacks are numbered from 1 to 80.
This sequence of numbers is called the "logical ID." It is the basis for how you
connect components to the control unit, as well as how the system assigns
station extension numbers and line numbers.
Notes:
■ Each 100D module is assigned 24 logical IDs even though the module has
only one physical line jack.
■ The 008 OPT module is assigned 12 logical IDs even though the module has
only eight physical station jacks.
■ Power failure transfer (PFT) jacks are not assigned logical IDs.
Planning Form Instructions
Mark the module placement on the "Control Unit Diagram" on the back of
Form 1.
1. Write the type of module to be installed at the top of each slot. Use the
lables listed in Table 2-1 (008 MLX, 408, etc.)
2. Write the type of jack (S= Station, L = Line) and the associated logical ID
for each line and station jack on each module.
Notes:
■
The "Unit Load" and "Auxiliary Power" blocks above the diagram are
reserved for occasions when equipment changes or maintenance require
the installation technician to manually compute the values. See System
Reference for details on computing unit loads.
■ Logical ID labels for each line and ststion jack are provided with the
system. When the control unit is assembled, the labels are attached to the
modules.
Figure 2-2 shows a completed “Control Unit Diagram" for a system with a large
processor module with 32 lines and 52 stations.
