The total number of blocks required to construct the MDF is 86.

The construction of the MDF is based on the block counts made above and on the factors listed below.
Note that in some installations, such as this one, the arrangement of the frames may increase or decrease

number of frames needed, despite the block count.

Location of the MDF. The size of the equipment room governs the location of the MDF. This
installation needs 25 ft of wall space close enough to the equipment to use either wall-mounted or
self-supporting frames.

Terminal-block mounting.  For an installation of this size, the terminal blocks can only be mounted

on frames. Choose one of the two types of frames to be used and whether the frames should be

wall-mounted or self-supporting.

— Wall-mounted frames.   Figure 10-1, 7-Module System Wall-Mounted on Type-1 Frames,  shows a

possible arrangement for a type-1 wall-mounted configuration requiring 12 frames. Although it
has significant room for the white field, it has little room for expansion of the purple field.
Expansion would require the use of very long jumpers and would exceed the jumper capacity of
frames. This configuration is not recommended.
