MDF/IDF DESIGN: DEFINITY GENERIC 2 WITH UNIVERSAL MODULES
7-19
●
Divide the terminations of the distribution cables among the zones in 100-pair increments.
(described earlier in this chapter under
Recommended Frames for Terminal Blocks)
may be used for a
zoned MDF that is terminating up to 10 modules.
Table
7-6, Module Allocation per Zone with Type-1
Frame,
shows the number of modules allocated per zone when you design an MDF with a type-1 frame.
Each type-1 frame can accommodate 3000 jumper pairs per side. Figure 7-10,
Zone Arrangement of
Type-1 Frame —
Plan View,
and figure 7-11,
Zone Arrangement of Type-1 Frame — Front View, Zone
2.
show a type-1 frame used in a zone arrangement.
NOTE:
Type-1 frames are not recommended for greater than 10 modules.
