The importance of the NID and ground rod:
A Kansas farm wife called the local phone company to report her
telephone failed to ring when her friends called and that on the few
occasions, when it did ring, her dog always moaned right before the
phone rang.
A telephone repairman proceeded to the scene, curious to see this
psychic dog or senile lady.
He climbed a telephone pole, hooked in his test set, and dialed the
subscriber's house. The phone didn't ring right away, but then the dog
moaned and the telephone began to ring.
Climbing down from the pole, the telephone repairman found:
1. The dog was tied to the telephone system's ground wire with a steel
chain and collar.
2. The wire connection to the ground rod was loose.
3. The dog was receiving 90 volts of signaling current when the number
was called.
4. After a couple of jolts, the dog would start moaning and then urinate.
5. The wet ground woul d c omplete the circuit, thus causing the phone to
ring.
This demonstrates that some problems CAN be fixed by pissing and moaning.

FYI....
Telco NID's would have grounded surge protector installed in it... So as to
protect them from surges.
Most likely when you are connecting the ATA to house wiring, you are
disconnecting it from the NID, and as such removing the surge protections.
You can continue to connect the ATA to house wiring, as long as you install
the appropriate surge protection on the phone wiring side of the house..
(the key here is that ground rod used for grounding the phone line, should
also be bonded with the ground rod used for electrical ground... if not then
you create a problem, and take hits every time it rains in hot weather).

We have several cases where a customer has a phone in an out building
plus the house. When they were with verizon they just had a copper
line between the house and building.
When we first started installing the phones, we would just hook our
ATA to the house wiring and everything worked great. Until the summer
rolled around and we started losing our ATA's due to lightning
issues.
We are now only connecting building using fiber. We still want to
extend the phone line to the out building using the fiber. Is there
an inexpensive way to take POTS to IP back to POTS?
