Demarcation point
The demarcation point is the point of interconnection between the
telephone company facilities and your building.
Location: It is usually a box located inside the building, within 15 feet
of the incoming phone wiring. In newer houses, it may be located near
the fuse box.
Wiring: The box will contain at least four posts used to branch the
incoming wiring to the internal phone wiring. The RED post should
have all the RED wires attached to it, the GREEN should have all the
GREEN wires attached etc.
This demarcation point shows two loops. Each loop has two lines
(four wires). Depending on how the jack is wired, the phone can be
plugged into Line 1, Line 2, or both.
