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 AAM.
• Use a punch-down tool to seat telephone lines between MDF blocks.
3.1.6 Telco-50 Cables
Telco-50 cables are used for data and voice applications with MDFs (Main Distribution
Frame), patch panels and distribution boxes. They can also be used as extension cables. Telco-
50 cables are made up of 25 twisted-pair copper wires.
Connect a Telco-50 connector to one end of the cable (see the hardware specifications
appendix for pin assignments) and connect the other end directly to an MDF; alternatively
attach RJ-11 connectors and connect directly to DSL modem(s).
