MDF/lDF DESIGN: SYSTEM 85 AND DEFINITY GENERIC 2 WITH TRADITIONAL MODULES
In addition to the preceding guidelines, observe these rules when designing zones:
●   
Mount the hardware on frames. For one-zone installations, wall-mounted frames may be used. For
two-zone installations, double-sided, self-supporting frames must be used.
●    
Divide the distribution cables (in 100-pair increments) as equally between zones as possible.  For
example, assume that an installation has two zones and a 300-pair distribution cable. You would
terminate 100 pairs at one zone and 200 pairs at the other.
●   
Do not add extra cable pairs to a distribution cable to achieve an equal number of terminations at all
zones. That is, do not add 100 pairs to the 300-pair cable in order to terminate 200 pairs at both
zones.
●   
Do not spread the equipment ports at the MDF.
2-13, Closet Cross-Connects Using Type-1 Frames, illustrates IDF cross-connections of distribution
cables originating from two different zones in the equipment room. Make sure that you label the IDF
cross-connections as follows:
●  
IO number for an extension
● 
Equipment line location (ELL) number for that extension
● 
Module number for that ELL
