2.6.1 MDF Connections Overview

Observe the following before you start:
• Refer to Chapter 5 on page 75

2.6.2 MDF (Main Distribution Frame)

An MDF is usually installed between subscribers' equipment and the telephone
company (CO) in a basement or telephone room. The MDF is the point of
termination for the outside telephone company lines coming into a building and
the telephone wiring in the building.
Figure 37 MDF (Main Distribution Frame) Wiring
• Connect wiring to end-user equipment to the lower ports of an MDF and connect
wiring from the telephone company to the upper ports of an MDF (see the
previous figure).
• Some MDFs have surge protection circuitry built in between the two banks;
thus, do not connect telephone wires from the telephone company directly to
your IES.
• Use a punch-down tool to seat telephone lines into MDF blocks.
