I changed two old phone jacks today and they both work. I have three other phone jacks in my house and one of the three stopped working as soon as I changed the two.

My kitchen phone jack was changed a year ago, and this is the one that I opened up and looked at before I changed two upstairs jacks today. These three are all wired the same and they all work. They all have two tan cables that each contain 4 wires: blue, white/blue stripe, white, orange. The kitchen jack had the two blue wires connected to the red terminal and the two white/blue stripe connected to the green terminal. I copied this configuration in the two upstairs jacks that I changed today. All three work great.

Another main floor jack works fine, but one jack stopped working today. I open it up thinking that maybe I should try to change the jack and I found that it only contains one cable with 4 wires: two white, a blue, and an orange. A blue and a white are connected to the jack and a white and the orange are not connected. This jack with only one set of 4 wires is the one that stopped working today when I changed the two upstairs jacks today. This is the jack that is actually used every day in my house, and now it's the only one that doesn't work. I didn't change it when I saw that it was different.

All of the jacks worked before I changed the two upstairs jacks today. I changed them because they were broken and hanging, unscrewed from the wall, but they worked. Now they look good and work great, but the most important jack in the house has no dial tone.

My phone service is a cable package with cable T.V. cable internet, and phone service packaged together. I looked all over the house, inside and out, and I couldn't find a NID or any other kind of access device.

Any suggestion? I can't put the old broken jacks back upstairs because I had to cut the wires off it, they didn't unscrew. They were really old.

Blue/white and white/blue or white is usually line 1, Orange/white and white/orange or white is usually line 2.
If these are solid white it is easy to get swapped with another pair. Maybe try other white?
White or White/blue connects to the Green on jack, and the Blue or Blue/white connect to the red on Jack.
Red and green on jack is all that is needed for a single line phone.
