Many phone companies have updated their color standards due to
the use of Cat 5 cable for most phone line installs, and keep
residential and business installs in line with each other. In the new
standard, there is no green, red, black or yellow wires, they have
been replaced by white/blue, blue/white, white/orange, and
orange/white. If the wire is primarily orange with white stripes
then that color is orange/white. Refer to the table below. The NID
labels will most likely have the old coloring scheme on them, and
most telephone wiring components you can purchase will still
reflect the original colors.
Function Old Color Standard New Color Standard
Tip 1 Green White/Blue
Ring 1 Red Blue/White
Tip 2 Black White/Orange
Ring 2 Yellow Orange/White
NOTES:
• The voltmeter measurement between the Tip and Ring should
be between 48 and 53 Vdc.
• Never run data wires and high voltage wires in the same
conduit. The high voltage wires may interfere with the data
wires and cause the system to malfunction.
• Reversed polarity will not damage the unit, however, some
telephones will not function properly.
Notes about wire connectors
(terminal blocks):
• Wire connectors can be
removed to simplify wiring.
• DO NOT overload wire
connectors. Use ONLY one
wire per hole.
