Summary: This telephone wiring diagram with photos and instructions will show you the direct steps to correctly wiring a telephone jack.


Telephone Wiring Diagram for Home Telephone Jacks


Wiring a Telephone Jack
After installing the Cat 3 - 3 pair phone wire I am ready to install the wall jack. You will have a wide variety of telephone jacks to choose from but the wiring for a single line phone service will be standard.

Keep in mind that the colors of the telephone wiring in your home will be typically one of two types or insulation colors. Older telephone wiring was a basic Cat-3, 4 conductor or 2-pairs with red, green, black, yellow.



Newer homes can have anything from Cat-3, 3-pair on up to Cat-5e, with 4-pairs, with the insulation colors being a combination of solid and solid with white for each wiring pair. The wire pair colors are blue, orange, green and brown.

Most wall phone jacks come configured
for a 2-line cord even thought a 1-line phone will
work just fine. You are probably wondering why the extra pairs? Well they will be used if you ever decide to add another phone line or if for some reason the primary pair stops working, then one of the spare pairs can be used.
Two Lines from one Telephone Jack
This style of phone jack can be pre-wired for a 2-line phone service, giving you the opportunity to have a second phone number that can be used for a business line or a fax machine.

Make sure the wires are well under the screw terminals. If you plan to use a cordless phone its always a good idea to install your phone jack wiring beside an existing wall receptacle which will be available for a low voltage transformer which may be required.
