5.To determine the number of extensions assigned for each module type, multiply the value in the Physical Jacks by Module Type column by the value in the Extensions Assigned column and write the results in the appropriate row in the Total Extensions Assigned column.

NOTE:

Since the system assigns an additional four extensions to each

008 OPT module, you must first calculate the Extensions Assigned by multiplying the number of 008 OPT modules (noted in the Number of Modules column) by 4 and then add this subtotal to the number noted in the Physical Jacks by Module Type column.

6.Add the column and record the result at the bottom of the column (System Totals).

Control Unit Diagram—Module Placement 2

This section describes how to use the Control Unit Diagram on Form 1 (page 2) to map the placement of the modules according to certain guidelines. Figure 2–1 on page -6 provides an example of a Control Unit Diagram for a system with 32 lines/trunks and 52 extensions. In addition, this section describes how to identify each jack on each module with respect to type (line/trunk or extension) and its associated logical ID. Each physical jack on the control unit is numbered sequentially from bottom to top and left to right with logical IDs as follows:

■Extension jacks are numbered from 1 to 200.

■Line/trunk jacks are numbered from 1 to 80.

This sequence of logical IDs is the basis for connecting components to the control unit, as well as for the assignment of extension numbers and line/trunk numbers.
