Checking Unlabeled Wiring

If a label is missing or damaged, use a tone device and a telephone handset to match like wires.
You need the following tools:
Tone device
I
Telephone handset
I
Telephone cord with an 8-pin modular plug
I
4-pair patch cord
I
Diagonal pliers or wire strippers
I
To match like wires, follow the steps below.
1. Insert the telephone cord's 8-pin plug into an outlet on the floor area.
2. Using diagonal pliers or wire strippers, cut off the end of the telephone cord to expose the
pairs.
3. Choose a single pair and then untwist the wires.
4. Attach to each clip one wire from the pair you have chosen. The clips extend from the bottom
of the tone device.
5. Turn on the switch on the outside of the tone device.
6. You hear a high-pitched, alternating signal.
7. Take the telephone handset and a 4-pair patch cord to the cross-connect field between the
control unit and the telephone.
8. Go to the blue field on the cross-connect field and, starting at the top left corner, push the
patch cord onto the first connecting block.
9. Using the diagonal pliers or wire strippers, cut off the other end of the patch cord and expose
the pairs.
Do not cut out too much of the cord, because you need the length to test the top rows of the
cross-connect field.
10. Attach the handset's clips, which extend from the base, to the exposed wires of the patch cord.
