Figure 9 MDF Wiring
• Connect wiring from end-user equipment to the lower ports of an MDF using a telephone
wire. 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 the IES-708-22A.
• Use a punch-down tool to seat telephone lines between MDF blocks.
3.2.4.3 Typical MDF Scenario
You want to install the IES-708-22A in an environment where there are no previously installed
MDFs. There is no phone service and you want to install the IES-708-22A for data-access
only. No connections from the CO lines are necessary.
You may connect using an MDF or attach RJ-11 connectors to the non-IES-708-22A end of
the Telco-50 cable and then connect to DSL modems directly.
