Planning Module Placement

Planning Module Placement
In addition to the processor module and power supply module, the system
supports several types of line/trunk and extension modules. Deciding how to
place the modules in the carriers consists of the following tasks:
1. Calculating the systems line/trunk capacity according to module types
2. Calculating the systems extension capacity according to module types
3. Mapping out module placement on the Control Unit Diagram according to
specific guidelines
This section contains instructions for each of these tasks.
For information about calculating unit load requirements, see Appendix F, Unit
Load Calculation.
For detailed information about modules and their specifications (including line/
trunk and extension capacity), see the descriptions of hardware components in
the Pocket Reference.
Forms Needed
Equipment List (if available)
Form 1, System Planning
Capacity for Lines/Trunks
Line/trunk capacity is the number of lines/trunks that can be connected to the
control unit. This section contains instructions for calculating the systems capacity
for lines/trunks according to the systems module types.
Planning Form Instructions
1. In the table under the Line/Trunk Capacity section of Form 1, System
Planning, fill in the number of each type of line/trunk module on the
appropriate line of the Number of Modules column.
2. Add the column and record the result at the bottom of the column on the
System Totals line.
3. For each module type noted, multiply the value in the Number of Modules
column by the value in the Trunks Supported by Module column; write the
results on the appropriate row under Total Trunks by Module Type.
4. Add the column and record the total line/trunk capacity of the system at the
bottom of the column, on the System Totals line.
