Industry-Standard Wiring Plans C-283
For smaller numbers of wires, such as wires for an individual telephone station or terminal, you may
use a second color code scheme. Table C-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.
