Whether it's because your teenage child wants a
phone in their room (and promised them one), you transformed one of
your rooms into a home office that needs a phone, or you just want
another phone in another room as a mere matter of convenience,
you'll need to install an additional telephone extension jack.
Some find such an installation somewhat complicated while others
don't. It will take some effort, but may be well worth it.
Here, what is covered is the installation of a surface-mounted phone
Caution: Because phone wires carry a small
amount of electrical current/voltage, before working on any phone,
make sure the phone is disconnected from the phone interface box
(that is usually located on an outside wall), and this includes disconnecting
its phone wire from the telephone jack.
Installing a telephone extension jack can be done in a few steps,
and here's how:
in the room you want your new telephone extension jack
installed, preferably along the same wall that already has a
telephone cable running against such a wall, tacked down with
fasteners like staples (or otherwise in the wall, requiring a
drywall keyhole saw to retrieve).
Tap into this
telephone cable at the area of the wall where the new telephone
extension jack will ultimately be installed: Using a pair
of pliers, let let loose about 1 foot of this telephone cable by
pulling out the fasteners, likely staples; be careful not to
pull harshly on such a cable as there are wires in there that
are easily susceptible to breakage. (If you are unable to
loosen about 1 foot of cable, you'll need to install a telephone
junction box for the installation of additional telephone cable,
which is not covered in these steps.)
this loosened cable where you intend to install the telephone
extension jack, using your long-nose multi-purpose tool.
the loosened cable, with both cut-ends of this cable still in your
sight, using the
long-noise multi-purpose tool again, strip each of the wires of
both such cut-ends of this cable of its insulation down to about a half an inch.
need to attach the above-mentioned bare wires of both such cut-ends
of this cable to the new telephone extension jack: Take each
pair of the same-colored wires (like green wires) and wrap them
around the terminal of the extension jack bearing the corresponding
color (green terminal). With these same-colored wires wrapped
around the same-colored terminal, immediately secure these wires to
the terminal by tightening the screw of the terminal with a
screwdriver. Repeat the same-wire, same-terminal connection
for each pair of wires until all pairs of wires are securely
connected (essentially green to green, red to red, yellow to yellow,
black to black).
Once you have
securely attached the color-coded pairs of wires to their
respective color-coded terminals of the phone extension jack,
next you will place the base of the phone extension jack at the
bottom of the wall where you want it to be installed/mounted:
Initially place the extension jack base against the wall where
you want it, mark the locations of the mounting screws of this
extension jack with a pencil and then remove the base from the
Then, use a
power drill, attached with the appropriate drill bit, to drill in
pilot holes through the previously made mounting-screw pencil markings.
Then, with the telephone extension jack base back into position,
flushed with the mounting holes read to be occupied by screws, take
a screwdriver and screw in all the screws through the extension jack
base and into the pilot holes, one by one.
Attach the cover of the phone extension jack to its now wall-secured
Next, using a
staple gun loaded with the appropriate staples, neatly and
securely attach the telephone cable along the bottom of the
wall, including specifically the incoming cable and outgoing
cable that stem from the newly installed telephone extension
phone cord of the phone into the newly installed telephone
extension jack. (At this time, all phone lines should be
re-connected, having been previously disconnected for safety
concerns.) Check the phone for the correct operability of
the new extension jack.
That's what it takes to install a telephone extension
