I Need Help With Installation

That's a protector for a single line. So what do you mean by line two and what connectors were you sent?

Well my broadband light red and I looked into it and found that line 2 is down. Here is the picture of the connector

If that is indeed your connection(s) line 2 would be on the orange/white  pair as line 1 is the blue/white pair from the outside drop.

As your showing line 1 inside wiring is on red/green, old quad wiring … line 2 should be on the yellow/black of the quad.

Unless you were originally a customer self install for lower speed internet such as 12 or below… I suspect there may be a NID on the outside with cat5e cabling for the inside wiring to the gateway location.

May want to check the colors of the wiring at the wall plate where the gateway resides.

Did line two ever work? Those are just scotch locks for splicing the lines together. You said line two is down which makes me think it did work. You've got another box somewhere.

Line 2 never worked.

OK let's get all this straight, by line two are phone lines and are you talking standard DSL with the filters on line one. First thing to do is go outside where there may be an NID (you can google testing phone line from NID) and if so see if line two is working out there. If it is see which color wires are on it. You need a starting point where it's working. 

Alright, thanks.
