Appendix A Industry-Standard Wiring Plans
For smaller numbers of wires, such as wires for an individual telephone station or terminal, you may use
a second color-code scheme. Table A-2 lists this color code and the usual correspondence with the
paired-wire color code. The alternate color code is included because sometimes the station wire uses the
first three pairs of the standard color code (white-blue, blue-white, and so on), while other times it uses
the six alternate colored wires.
