Color Code Chart
The six-position plug and jack commonly used for telephone line connections
may be used for RJ11, RJ14 or even RJ25, all of which are actually names of
interface standards that use this physical connector. The RJ11 standard
dictates a 2-wire connection, while RJ14 uses a 4-wire configuration, and
RJ25 uses all six wires. The RJ abbreviations, though, only pertain to the
wiring of the jack (hence the name “registered jack”); it is commonplace
but not strictly correct to refer to an unwired plug connector by any of
these names. Typically you’ll find the RJ-11 and RJ-14 on your Plain Old
Telephone Service (POTS) though your RJ25 typically is found in an
Integrated Services Digital Network (ISDN) Line. It is the communication
standards that lets telephone lines to carry digital, voice, video, and
network services.

Note

While the old solid color code was well established for pairs 1 and 2,
there are several conflicting conventions for pair 3. The colors shown above
were taken from a vendor of “silver satin” flat 8-conductor phone cable
that claims to be standard. Other 3 pair solid (old) bellwire cables may
substitute white for orange. At least one other vendor of flat 8-conductor
cable uses the sequence blue, orange, black, red, green, yellow, brown and
white/slate.
Holding the connector in your hand tab side down with the cable opening
toward you, the pins are numbered 1-6, left to right.
In modern structured wiring Cat5e or Cat6 is commonly used in homes and
buildings. The Cat 5e and Cat 6 data lines are often used for both voice or
data. The color codes above are the standard and defined within wiring
guides.
The CAT 3 Cable can also be used for the RJ-14 Pinout with the same color
code as the CAT5 and CAT6. The internal pairs to the pinout are trasmit and
recieve (1 and 1), while the 2 side pairs (2 and 2) are your power.
The RJ25 is going to be the standardized phone cable for your ISDN
(Integrated Services Digital Network) it allows phones such as the (STE) to
carry digital, voice, video, and network services. Though there is an RJ45
port connection, you can implement the RJ25 to push all information if the
Port has the proper configurations at the switch. For an RJ25 you’ll need
to use CAT5 or CAT6 since a CAT3 is only a 4 wire cable.
