When I got up this morning, my phones have no dial tone.

The first thing I did was look for a phone off the hook.
Then I went out to the NID, and plugged a phone into it. Works fine.
So the problem is somewhere in the wiring.

I checked the wiring at the terminals. Everything is good, solid
connections.

I went around to every jack in the house and plugged in a phone.
Nothing.

I'm at a loss. I expected to find a loose wire in the NID, but now I
don't know how to proceed.

Don't forget that there are a lot more things than phones plugged into
the phone line these days. Modems, burglar alarms, separate bells or
lights, special electronic boxes (I have one that does redial, hold,
and memory dial for the whole house with one box.)

If there is a monitored alarm system installed in
the home there will be a special jack "RJ-31X"
that the alarm panel plugs into. This jack has a
pair going in and a pair going out. When the alarm
panel is unplugged from the RJ-31X, the pairs are
hooked together. Since alarm systems are designed
to seize the phone line, the jack is there in case
the alarm malfunctions. You unplug the alarm and
jack switches the phones back on. For some very
good information on modern home phone wiring, take
a look at this web site:
