Follow these steps to connect subscriber wiring to the punch-down
block. Consult the following diagram while making connections.

Telephony Modem line that you are connecting.
2 Route the wire pair to reach the right side of the punch-down block.
3 Using the punch tool, punch the tip wire into the first of the two
connections for the line, and the ring wire into the second connec-
tion. It is not necessary to strip the wires before punching.

phone service (clips for line 1 are shown above).
