Installing Telephones and Adjuncts

Checking Poorly Labeled Wiring

If you do not understand the labeling system used or a label is missing or damaged, use a tone device and a telephone handset to match like cables.

Hardware

tone device

telephone handset

telephone cord with an 8-pin modular plug

4-pair patch cord

Tools

diagonal pliers or wire strippers

Procedure

1. Insert the 8-pin of the telephone core into an oulet 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 untwist the wires.

4.Extending from the bottom of the tone device are two clips. Attach one wire from the pair you have chosen to each clip.

5.Turn on the switch on the outside of the tone device. You will hear a high-pitched, alternating signal.

6.Take the telephone handset and a 4-pair patch cord to the cross-connect field between the control unit and the telphone.

7.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.
