6.2 RJ-11 (Telephone) Cable
The RJ-11 cable is commonly used for telephone connection.
Caution: Do not plug a phone jack connector into an RJ-45 port.
Wiring Conventions
For telephone connections, a cable requires one pair of wires. Each wire is identified by
different colours. For instance, one wire might be red and the other, red with white stripes.
Also, an RJ-11 connector must be attached to both ends of the cable.
Each wire pair must be attached to the RJ-11 connectors in a specific orientation. The
following figure illustrates how the pins on the RJ-11 connector are numbered. Be sure to
hold the connectors in the same orientation when attaching the wires to the pins.
