- TIP is green, RING is red. This is the wire pair in the middle of
- the modular plug. Wire pairs start with the two wires in the middle
- of the plug and go out towards the edge, so on a 6-wire mudular
- plug, the pairs would be 3-4, 2-5 and 1-6. On a standard residential
- installation, yellow is ground and black is transformer +. The trans-
- former was used to light the dials of Trimline and Princess phones.
- Newer lighted-dial phones use a low-current LED which draws its
- power directly from the phone lines. Blue and white depends on your
- application. Is this the information you wanted?
