Connect new phone line to ONT

Hi,

 Curious if you can help me out.  I have verizon Fios TV + Net + 1 landline.  There are four outlets in the house, 2 on first floor, and 2 on 2nd floor.  A few days ago Verizon came by to upgrade my net speed to 300/300 from 100/100.  In order to do that they had to connect a cat 5 cable into my Verizon Router along with the existing Coax connection.  Everything went well except that there now is a problem with the landline.  The 2 outlets on the first floor work fine, but the 2 outlets on the second floor do not work (no dial tone).   I went to the ONT box to check and see if any of the telephone wires (that run into the house) were loose but they were all connected to the block.   I did notice something strange. I only have one landline but the POTS L1 and L2 on the ONT are connected.  L1 is wired to the block on the left side (the side w the red/green tab), and L2 is wired to the block on the right side (the one w the black/yellow color tab).    Since I only have one telephone line, why are there two POTS connection on the ONT?   The wire that runs into my house behind the wall has 6 wires side (I was told by the tech that is a cat 5???)  The wire that runs out from the wall is connected to the block.  One pair (blue and white) is connected to the red/green color clip on the block, and another pair (orange and orangewhite(?)) is connected to the black/yellow color clip.

I want to see if I can fix it myself before calling verizon.

Thanks.

It isn't unusual for a Verizon technician to connect both of the POTS line jacks on the ONT to the terminal strip.

Despite both of the sides being connected, L1 is the only active jack.

All tip/ring pairs wiring going to the jacks throughout the house should connect to the terminals on the left side of the strip (the L1 side). If the existing in-house wiring is what is known as JK (aka Jake), the green/red wires may all go to the first floor while the black/yellow go to the second floor.

If the black/yellow wires currently go to the right side of the strip, try moving them to open positions on the left side of the strip and see if that resolves the issue.
