I don't know if this is the right group to be asking this question in, but perhaps someone can help me out.
I have a rats nest of phone wires converging on something called a "66B4-B Jumper Block" down in my basement. I have phone jacks with
4-wire line at various locations in the basement, and I can only get one line to work although we have 2 lines in the house. I bought a little LED tester that plugs into the phone jack, and it checks for crossed wires, whether there's 2 lines present, and other things. I suspect that something is screwed up at the jumper block because it's just too easy to snag a wire there out in the open and pull it loose.
Rather than calling in the phone company, or spending $100 on something called a tone generator, is there any cheaper way to find out what's wrong with this line?
And if a tone generator kit is the only answer, can anyone tell me where I can get the bare minimum unit new or used? Or if someone knows of a web site that ttoally explains how to wire a Jumper block, I do have the line in question ID'd, I just don't know why it's not working as a 2-line system.
Thanks in advance for any/all help.
Mike
