In its role as the demarcation point (dividing line), the NID separates the telephone company's equipment from the customer's wiring and equipment. The telephone company owns the NID itself, and all wiring up to it. Anything past the NID is the customer's responsibility. To facilitate this, there is typically a test jack inside the NID.

If there is a problem on one phone and not the others, examine this phone's jack and line back to the junction box.

If you have a junction block or an entrance bridge, physically separate the telephone company's wiring from the block or bridge. Make sure none of the wires touch! This action will "open" the circuit and allow you to use a multimeter to test the continuity of your wiring. A wire that has "continuity" allows electricity to freely flow through it.
