Steps for Installing a Modular Telephone Jack

phone-jack-install-2.jpgInside of the old phone plate we are replacing. There is one set of wires (one solid blue, the other white with blue stripe) that is attached to the old plate. 

Green set and orange set of wires also are coming out of beige telephone cable (partially covered with lavender paint in the photo), but are not being used. 




Cut back the outer cable housing (beige in our photo) containing the colored wires, being sure not to cut the plastic casing on each individual wire. Determine which color code grid on the jack corresponds to your wiring using the chart on the package instructions. The wiring in our picture corresponds to the bottom row of colors. Push solid blue wire and white wire with blue stripe into their correct slots with your fingers. (Repeat these next steps for each set of wires you have.)

Push black bridge clip all the way down to prevent wires from coming out.

phone-jack-install-15.jpgThis type of plate is too wide and too deep to be covered by our standard telephone jack plates, so if needing to replace this style, we recommend purchasing the same type. Buy wall mounted phone jack covers.




phone-jack-install-16-daisy-chain.jpgThe type of wiring inside this box is called a daisy chain. Only one main cable is strung through this building. The cable comes in, is cut and attached to the telephone jack, then goes out of each box, so the phone jacks in other rooms are are all connected in one long chain. (Pairs of wires [two blues, two whites with blue stripes] are twisted together then placed under the screw to make the connection.) This type of arrangement won't work with a modular telephone jack, so our plates won't work.
