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.

Table 12: RJ-11 Pinout Information
The RJ-11 pair of wires is wired so that pins 3 and 4 are connected to the Ring and Tip, which meets
the following requirements:
EIA/TIA-IS 968
CS-03 Issue 8, Part III requirements.
Warning: The RJ-11 cable should comply with UL 1863 and CSA C22.2 No 233 standards.
