Insert the 8-pin of the telephone core into an oulet on the floor
area.
Using diagonal pliers or wire strippers, cut off the end of the telephone
cord to expose the pairs.
Choose a single pair and untwist the wires.
Extending from the bottom of the tone device are two clips. Attach one
wire from the pair you have chosen to each clip.
Turn on the switch on the outside of the tone device. You will hear a
high-pitched, alternating signal.
Take the telephone handset and a 4-pair patch cord to the
cross-connect field between the control unit and the telphone.
Go to the blue field on the cross-connect field and, starting at the top
left corner, push the patch cord onto the first connection block.
