On a single home landline:

My landline phone quit working this weekend. I knew I'd not get repair
service until Monday. I opened the connection box outside and found a
broken wire. Then another one broke while I was working in there.
So I took off all the wires, restripped them all, and started over with
"fresh" wires.
The source wires are both black. and I had them off the main connection
box outside. I did not label them (probably should have).

How do you know which source wire should go to the red and which should
go to the green (on the house wires)?
I put these colored ones to the same screws that they were originally,
but I could have reversed the black (source) wires....

Or dont it matter?????

The phones do work, and so does my internet, so either I guessed right,
or it works either way !

It used to be that touchtone phones wouldn't dial if you reversed red
and green, but they fixed that 20 or 30 years ago. I think the fix
was retroactive, that is, it made old phones work backwards too.

How many phone lines do you have in your house? Any other phone
company lines?

If only one line, you only need two wires.

My friend in a NJ suburb of NYC bought a house built in the 20's or
40's or so, and it only had 3 phone wires coming into it. Even though
only 2 are needed, TPC always installs more than needed. Perhaps 3
seemed like a lot when the house was built.
