Section 3: Installing Extensions and Trunks
Install an RJ11/RJ45 socket for each extension. The socket should be within two metres of the
phone due to the length of the line cord supplied.
For each extension, run one-pair station cable to an RJ11 (or RJ45) socket.
Terminate the pair to pins 3 & 4 for the RJ11 socket (pins 4 & 5 of the RJ45 socket). Refer to
