7. MDF/lDF DESIGN: DEFINITY GENERIC 2 WITH UNIVERSAL MODULES
This chapter recommends the terminal blocks and frames best suited for constructing a main distribution
frame (MDF) for the DEFINITY™ Generic 2 Communications System (hereafter abbreviated to
DEFINITY Generic 2 or Generic 2) with universal modules, presents the guidelines for their design,
presents some guidelines for the intermediate distribution frame (IDF) design, and briefly discusses

presents some guidelines for the intermediate distribution frame (IDF) design, and briefly discusses
labeling for the MDFs and IDFs.
This chapter also presents some general guidelines, cross-connect hardware recommendations, and frame
recommendations for designing IDFs. They are simplified because IDFs, unlike the MDF, vary greatly,
and only the most general design guidelines can be applied.

The 110A comes in several models that are called terminal blocks. Each terminal block is composed of
a wiring block and a unique combination of connecting blocks. A wiring block is where the equipment,
distribution, or central office (CO) cables terminate. The connecting block, which snaps onto the front
of the wiring block, is where the jumper wires are attached to establish a path from the pairs in one
cable to the pairs in another cable.

In order to simplify the design of wiring installations, only two terminal blocks — the 110AB1-300 and
the 110AB1-100 — are recommended for Generic 2 with universal modules. Generally, the 300-pair
terminal block is preferred for the MDF. The IDF can be designed
