RJ-11 (Telephone) Cable
The RJ-11 cable is commonly used for telephone connection.
Wiring Conventions
For telephone connections, a cable requires one pair of wires. Each wire is identified by different colors. For
example, 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.

The RJ-11 pair of wires is wired so that pins 3 and 4 are connected to the Ring and Tip, which meets the
