In the new standard, there is no green, red, black or yellow wires, they have been replaced by white/blue, blue/white, white/orange, and orange/white.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. • Wire connectors can be removed to simplify wiring. • DO NOT overload wire connectors. Use ONLY one wire per hole. Function Tip 1 Ring 1 Tip 2 Ring 2 Old Color Standard Green Red Black Yellow New Color Standard White/Blue Blue/White White/Orange 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.
